Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants… Bonne découverte!
La guerre contre Bitcoin
Bitcoin est peut-être le meilleur outil de liberté économique de cette génération, et peut-être depuis plusieurs générations. Malheureusement, Bitcoin a été furieusement étouffé par une guerre civile brutale depuis environ cinq ans maintenant; menée par des ingénieurs sociaux professionnels de certaines des entreprises les plus puissantes des médias sociaux. Leur talent dans l'art et la science de la manipulation a permis aux "Bitcoiners" de se battre largement entre eux plutôt que de chercher à créer des modèles commerciaux innovants basés sur les données qui pourraient révolutionner l'économie mondiale via Bitcoin.
À la suite de la guerre civile de Bitcoin, trois versions concurrentes de Bitcoin ont vu le jour (BTC, BCH et BitcoinSV ), mais il en est de même pour environ 3000 autres projets et jetons de « crypto-monnaie » se faisant passer pour des entreprises légitimes, souvent jusqu'à un "exit scam" presque garanti, le fait de disparaitre du jour au lendemain avec tout l'argent des utilisateurs. Le principal bienfaiteur de la guerre civile Bitcoin a été Ethereum: une cryptomonnaie qui fonctionne comme une machine à états mondiale et permet un déploiement facile de tokens et de contrats intelligents. Mais le protocole Ethereum ne peut pas évoluer, et parmi les milliers de projets lancés, seule une poignée pourrait même être présentés comme pouvant devenir des entreprises légitimes. La plupart des autres sont des stratagèmes de Ponzi ou des émissions d'actions illégales enrichissant les développeurs et escroquant les investisseurs amateurs.
C'est dans ce contexte que les défenseurs de BTC et de BCH, les porte-parole d'Ethereum et les altcoiners (nom donné pour englober toutes les autres cryptomonnaies) de tous bords s'alignent pour attaquer sans cesse le protocole Bitcoin préservé uniquement par le réseau BSV. Une industrie composée presque entièrement de criminels, de fraudes et d'arnaqueurs s'est unie contre BSV citant - et c'est là l'ironie! - une prétendue fraude et arnaque présumée qui serait l'existence même de BSV.
Nous devons nous demander pourquoi ?
Quel est le différenciateur clé de BSV?
Pourquoi tous les arnaqueurs se sont-ils unis contre lui?
Je suis fermement convaincu que pour la plupart, la motivation est la peur de la capacité de BSV à absorber l'économie mondiale et tous les autres projets «crypto» qui vont avec. Pour les autres, ou ceux qui ne comprennent pas le pouvoir du Bitcoin, ils sont entraînés dans une guerre civile et culturelle qui les dépasse. Il est essentiel de comprendre les pouvoirs en jeu et leurs implications pour Bitcoin et l'économie mondiale.
Une histoire brève de Bitcoin
Bitcoin a été lancé avec un "livre blanc" sur la liste de diffusion de cryptographie en 2008. Le pseudonyme « Satoshi Nakamoto » a déclaré une solution au problème de la double dépense. Or il s'agit là du problème de tous les systèmes de paiement électronique précédents, et c'était le seul facteur limitant l'adoption d'une monnaie digitale fonctionnelle. Mais qu'est-ce que le problème de la double dépense ? Pour faire simple, il était impossible de prouver exactement qui possédait quelles unités d'argent sur des registres distribués, de sorte que les utilisateurs ne pouvaient pas avoir confiance dans le système, et ces projets mourraient assez vite. Bitcoin a résolu ce problème avec un concept appelé la « preuve de travail ». Il pose la question: qui a utilisé le plus de puissance de calcul pour résoudre des énigmes arbitraires ? ceci afin de rendre compte de l'état du registre d'une manière qui coûte de l'argent, de sorte qu'il y ait une incitation économique à tenir un compte honnête des avoirs de chacun des participants. Ce processus est souvent appelé « exploitation minière » car les nœuds honnêtes qui maintiennent l'état du registre sont récompensés pour leur travail avec des nouveaux Bitcoins toutes les dix minutes - un peu à la même manière d'un mineur d'or qui est récompensé par de l'or en échange de son travail.
Étant donné que Bitcoin n'avait aucune valeur lors de son lancement, il était extrêmement facile à miner et également gratuit d'envoyer des tonnes de transactions. En théorie, il s'agissait d'un vecteur d'attaque par déni de service (DoS). Une attaque DoS ou DDoS se produit lorsque les nœuds d'un réseau sont inondés de plus de données qu'ils ne peuvent en gérer et qu'ils se mettent donc à planter. Sur le jeune réseau Bitcoin, un crash comme celui-ci aurait été considéré comme un échec du réseau. Pour empêcher cela, un plafond de 1 Mo de données par chaque dix minutes de transactions a été codé en dur dans le logiciel - semant la première graine de la guerre civile Bitcoin. De 2009 à 2017, cette limite de 1 Mo sur le total des transactions était l'aspect technique le plus controversé du bitcoin et le déclencheur de la plus grande guerre civile virtuelle de l'univers de la cryptomonnaie.
Pourquoi est-ce aussi important?
Une seule transaction basique Bitcoin est relativement petite du point de vue des données, donc 1 Mo toutes les dix minutes donne environ trois à sept transactions par seconde avant que le réseau ne devienne trop encombré. Satoshi Nakamoto le créateur, a plaidé pour un nombre de transactions du niveau de Visa et bien plus, ainsi que son successeur direct en tant que développeur principal du projet, Gavin Andresen. Certains des premiers Bitcoiners influents comme Mike Hearn et Jeff Garzik ont ​​également plaidé pour plus de données par bloc pour permettre à Bitcoin de se développer et de rester le meilleur système de paiement électronique. Ils étaient pour des «gros blocs» contrairement au camp des «petits blocs» qui préconisaient une permanence de la limitation de 1 Mo des blocs.
Le camp des "petits blocs" estiment que Bitcoin n'est pas un réseau de paiement, mais plutôt qu'il s'apparente davantage à une banque décentralisée conçue pour stocker des Bitcoins qui ne bougent jamais: une sorte de coffre-fort d'or numérique. Ils voulaient que la limite de taille des blocs de 1 Mo reste permanente sous les auspices de chaque personne exécutant un «nœud complet» sans avoir à payer trop d'espace sur le disque dur. Cela signifierait qu'en période de congestion, les frais de transaction deviendraient absurdement élevés, mais cela n'aurait pas d'importance car le bitcoin ne devrait pas être utilisé pour des envois sauf en grosses quantités de toute façon, selon eux. En décembre 2017 les frais de BTC ont ainsi atteint les $50 par transaction. L'autre problème est que s'il est bon marché de rejoindre la gouvernance de Bitcoin, alors le réseau est facile à attaquer par Sybil, et je dirais que BTC est régi par des sybilles à ce jour.
Le camp des "gros-blocs" estime que tout le monde sur terre devrait être en mesure d'échanger et de faire ses affaires sur Bitcoin pour des frais infimes, de l'ordre d'un centième ou millième de centime par transaction, afin d'apporter à la population mondiale la liberté monétaire, y compris aux pays les plus pauvres qui sont gardés en dehors du système actuel car considérés comme pas assez profitables pour des entreprises comme Visa.
Les "petits-blocs" pensent que tout le monde devrait être en mesure de gérer soi-même le registre mondial chez soi, mais que seules certaines personnes très riches devraient pouvoir effectuer des transactions, ce qui est le cas quand les frais sont à $50 par transaction comme en 2017.
Après des années de querelles, en 2017, Bitcoin s'est scindé en deux chaînes distinctes, et en 2018, il s'est à nouveau divisé.
Alors quelle est la différence entre ces trois versions ?
BTC est actuellement la version qui a le prix le plus élevé, avec la plus petite taille de bloc et la plus grande puissance de calcul. On peut dire que BTC à gagné la guerre médiatique. Malheureusement, il est régi par des développeurs et des sybilles qui contrôlent le consensus grâce à une utilisation intelligente de logiciels malveillants appelés «soft-fork» qui leur permet de saper les règles du Bitcoin. Ils utilisent ce pouvoir pour changer les règles des transactions en mentant aux nœuds et en leur disant de les valider quand même. Toute la culture BTC consiste à acheter du BTC afin de le conserver jusqu'à un moment dans le futur où il serait revendu à un prix exorbitant. Le but est de spéculer au maximum. Les paiements avec BTC, particulièrement les petits paiements, ou les transactions de toute nature non-monétaires, sont méprisés.
BCH est un réseau basé sur Bitcoin qui pense que les blocs devraient être à peine légèrement plus grands, mais ils ont également des développeurs en charge des règles, tout comme BTC, et ils pensent que Bitcoin devrait être utilisé uniquement pour le commerce de détail, mais rien de plus. Le réseau change de règles tous les six mois. Les transactions non commerciales sont en général méprisées. Un nouveau scindement de BCH est prévu pour novembre 2020 suite à des conflits internes et l'incapacité à avoir un système de gouvernance dans un projet où les règles changent en permanence.
BSV est la version restaurée du protocole Bitcoin original avec tous les paramètres ouverts afin que les nœuds honnêtes puissent s'engager dans un consensus conformément au livre blanc de Bitcoin - par la preuve de travail ! Le protocole est gravé dans la pierre afin que les développeurs de logiciels ne puissent pas bricoler les règles. Cela permet aux entreprises de planifier des décennies d'utilisation du réseau et d'investir en toute confiance. Il s'agit d'apporter une réelle innovation technologique au monde plutôt que de spéculer. En tant que seul réseau bitcoin totalement sans besoin d'autorisation, le commerce de toute nature est encouragé sur BSV. Tout, allant des réseaux sociaux aux expériences de science des données météorologiques ou aux tests de disponibilité du réseau, est encouragé. Paiements de détail, tokenisation, ou tout autre type de contrat intelligent est simple à déployer sans limitations. Bitcoin SV n'a aucune limite dans son protocole sauf l'esprit humain, l'innovation et l'esprit d'entreprise. Il vise également une adoption mondiale notamment par les pays pauvres afin d'apporter la liberté monétaire et l'inclusion à l'économie mondiale de ceux que les grandes entreprises actuelles comme Visa dédaignent comme pas assez profitables pour leur accorder leur services.
Et c'est la racine de la haine envers BSV.
Les "petits-blocs" ont investi toute leur réputation et leurs moyens de subsistance sur la notion que le bitcoin est incapable de s'adapter. Pendant des années, des experts présumés ont convaincu de nombreuses personnes que les limites de taille de bloc de 2 Mo, 8 Mo ou 22 Mo casseraient littéralement Bitcoin. Ils ont furieusement mis en jeux leur réputation sur ces fausses notions. Et ensuite, BSV a eu de nombreux blocs de plus de 100 Mo. En fait, il y en a même eu quelques-uns de plus de 300 Mo! prouvant que les petits-blocs se trompaient depuis le début sur les limites du réseau. Mais cette prise de conscience est une menace pour l'hégémonie de l'histoire médiatique qui a été crée sur Bitcoin. Depuis 2015, lorsque le Dr Craig Wright est apparu sur les lieux pour expliquer que le bitcoin avait en réalité ZERO limitations, il a créé un tollé massif parmi l'intelligentsia des petits-blocs. Les leaders d'opinion de l'époque étaient payés pour prendre la parole lors de conférences où ils expliquaient à tort que Bitcoin n'était rien d'autre qu'une réserve de valeur rare sans autre utilité, et surtout pas à usage des plus pauvres. Le Dr Wright parlait de l'échelle illimitée du réseau, de son exhaustivité de Turing, de l'objectif d'inclure enfin les plus pauvres dans l'économie mondiale, et d'autres notions inconcevables (à l'époque) sur Bitcoin. Sa passion et ses connaissances se sont heurtées à des calomnies et des railleries. Ils se sont concentrés sur l'attaque de son personnage au lieu de discuter de Bitcoin!
C'est devenu l'une des principales méthodes d'attaque des petits-blocs. Lorsque de gros-blocs parlent des capacités de Bitcoin, ils sont ridiculisés en tant qu'escrocs et le sujet est toujours dirigé très loin de la discussion technique, car les petits-blocs savent bien qu'ils sortiraient perdants. Ils fouillent les dossiers personnels et cherchent des moyens de faire taire les gens du camp des grands-blocs de Bitcoin par des attaques personnelles - de la même manière que les guerriers de la justice sociale s'engagent dans la culture d'annulation contre leurs ennemis politiques.
Qui est le Dr Craig Wright et que fait-il?
Craig Wright est le scientifique en chef d'une société de recherche sur Bitcoin au Royaume-Uni appelée nChain : une société de 150 à 200 informaticiens. Craig dirige l'équipe qui étudie les possibilités de Bitcoin et de ses applications dans le monde. Il est l'un des experts en criminalité numérique les plus reconnus au monde avec les certifications SANS et GIAC ainsi que les titres GSE CISSP, CISA, CISM, CCE, GCFA, GLEG, GREM et GSPA. En outre, il est un polymathe multidisciplinaire de troisième cycle: un doctorat en informatique, économie et théologie et titulaire d'une maîtrise en statistique et en droit commercial international.
En 2015, il a également été exposé par une publication conjointe de WIRED et Gizmodo en tant que Satoshi Nakamoto, le créateur de Bitcoin. Quelques jours après cette révélation, les gens qui le soutenaient ont vu leurs clés d'accès au code de Bitcoin révoquées, et de nombreux autres ont été instantanément bannis. Craig a été mis sous enquête par le bureau des impôts australien pour ce qu'il considérait être une erreur de comptabilisation probable de ses bitcoins. Les retombées ont été agressives et rapides, avec une gigantesque armée de petits-blocs, organisée sur Reddit et d'autres forums, et nouvellement financés par l'argent de la startup pro petits-blocs appelée «Blockstream». Leur message était clair: Bitcoin doit garder de petits blocs. Le Bitcoin ne peut pas évoluer et doit rester réservé aux riches, et toute personne proche de Craig Wright sera harcelée pour se conformer à une armée de comptes Twitter anonymes et sans visage.
Voici un schéma qui retrace les financements de Blockstream et révèle comment le groupe Bilderberg, la banque centrale américaine (FED) et Mastercard on pris le contrôle du réseau BTC via Blockstream afin de le soumettre à leur propre profit: https://imgur.com/eFApDVE
Au cours des années suivantes, Ira Kleiman, frère du défunt Dave Kleiman, a poursuivi Craig Wright en justice pour sa part du prétendu «Partenariat Satoshi Nakamoto», affirmant que son frère Dave était plus impliqué qu'il ne l'était réellement, et l'affaire est en cours actuellement, jusqu'à courant 2021. Ira Kleiman pense que Craig est Satoshi et il a investi une fortune incalculable dans cette attaque et a obtenu l'argent d'investisseurs extérieurs pour poursuivre sa poursuite. Il est clair que les bailleurs de fonds d'Ira pensent que Craig est également Satoshi.
Les critiques qualifient souvent la révélation publique et le procès public de Wright de ternir énormément sa réputation, mais il convient de noter que les deux sont arrivés à Wright malgré sa volonté et qu'il ne souhaitait clairement pas être pris dans l'une ou l'autre situation.
Au lieu de cela, Craig est un défenseur passionné de la vision d'un Bitcoin avec de gros blocs, appelant à la professionnalisation, à la légalisation et à l'utilisation mondiale de Bitcoin pour une utilisation à tous les niveaux du commerce. La réponse à la passion de Craig et à ses affirmations a été d'attaquer sa réputation et d'endosser Internet avec le surnom de «Faketoshi». Lorsque de simples brimades ont échoué contre le Dr Wright, des attaques ont été intensifiées pour remettre en question ses divers diplômes, des pétitions aux universités pour enquêter sur lui pour plagiat dans divers travaux, y compris des thèses de doctorat, etc. Wright a même revendiqué des menaces contre la vie des membres de sa famille et il y a plus qu'une preuve que, selon Ian Grigg, une des légendes de la cryptographie: «des gens sont morts pour Bitcoin, croyez moi, des gens sont morts».
Les attaques en cours
Cela ne peut être assez souligné: la communauté des petits-blocs est construite autour de tactiques d'ingénierie sociale professionnelles. Gregory Maxwell, co-fondateur de la société Blockstream, a été formé à la pratique de l'ingénierie sociale et l'a utilisé de manière si subversive comme un outil de propagande pendant son mandat en tant que modérateur rémunéré de Wikipedia, qu'il a finalement été démis de ses fonctions avec les journaux d'administration citant une litanie d'infractions, notamment:
«Gmaxwell s'est engagé dans la création de faux comptes en masse…» - Alhutch 00:05, 23 janvier 2006 (UTC)
«Menaces, insultes grossières, usurpations d'identité d'un administrateur», -Husnock 03:18, 25 janvier 2006 (UTC)
«Son comportement est scandaleux. Franchement, il est hors de contrôle à ce stade. Son comportement d'intimidation doit cesser.» - FearÉIREANN 19:36, 22 janvier 2006 (UTC)
«Sa liste de contributions est hors de propos. C'est du vandalisme. C'est un comportement auquel je m'attendrais d'un éditeur en furie, et franchement, c'est ce qu'est Gmaxwell.» - Splashtalk 20h00, 22 janvier 2006 (UTC)
«Prétend être un administrateur, menaçant de bloquer les personnes qui ne sont pas d'accord avec lui, fait régulièrement des attaques personnelles» - SlimVirgin (talk) 12h22, 22 janvier 2006 (UTC)
Il passe beaucoup de temps sur Reddit et d'autres forums à semer la peur sur les dangers des gros blocs, et il a été surpris en train de faire semblant d'être plusieurs comptes à la fois en train d'avoir de très longues discussions techniques sur Reddit destinées à submerger les nouveaux arrivants avec ce qui ressemble à un débat intellectuel contre une version de Bitcoin libéré de ses limites.
Qui d'autre est attaqué?
L'autre cible commune de la machine de guerre médiatique anti-BSV est Calvin Ayre: un milliardaire à la tête de l'empire du groupe Ayre. Calvin est un entrepreneur canadien et antiguais qui a lancé un incubateur Internet à Vancouver au tout début du boom Internet. Fils d'un éleveur, Ayre est surtout connu en dehors de l'économie Bitcoin pour la création et la professionnalisation de l'industrie du jeu sur Internet. Plus particulièrement, sous la marque Bodog, Ayre a aidé à moderniser les lois financières américaines obsolètes en poussant les limites dans les marchés gris qui existent où les dollars américains sont utilisés à travers les frontières pour s'engager dans un commerce juridiquement compliqué comme le jeu d'argent. Son travail dans ce domaine lui a valu une petite fortune et un passage sur la liste des «plus recherchés» du gouvernement des USA pour blanchiment d'argent. C'est un point sur lequel les petits-blocs aiment se concentrer, mais ils le sortent complètement de son contexte. Calvin a finalement plaidé coupable à une accusation mais a été le fer de lance de la modernisation des lois américaines qui existent aujourd'hui sur les marchés. Il est respecté pour son travail dans l'industrie du jeu, des médias et de la philanthropie. Calvin est le bienvenu aux États-Unis malgré la critique souvent citée selon laquelle il serait une sorte de hors-la-loi.
Calvin Ayre
Dans l'économie Bitcoin, Ayre est une figure de proue dans la gestion de nœuds Bitcoin honnêtes depuis plusieurs années sous les marques CoinGeek et TAAL, et il est un investisseur dans nChain ainsi que plusieurs startups de l'espace BSV. Bien qu'il soit probablement le plus gros investisseur à ce jour, il n'est pas le monopole que les petits-blocs laisseraient croire. Il est important de comprendre que des segments entiers de l'écosystème BSV existent complètement en dehors de son influence.
Twetch, par exemple, est une entreprise indépendante appartenant à l'écosystème BSV, célèbre pour ses attaques contre les médias sociaux centralisés qui abusent de la censure. Ils sont même connus pour se moquer des entreprises qui acceptent l'argent d'Ayre, en plaisantant que Calvin possède tout sauf Twetch. Bien sûr, ce n'est pas vrai. Un autre excellent exemple est l'investisseur / entrepreneur indépendant Jack Liu : ancien dirigeant de Circle et OKEX. Liu possède la marque de hackathons CambrianSV ainsi que des propriétés précieuses dans l'espace BSV telles que RelayX, Streamanity, Output Capital, FloatSV et Dimely.
Les autres acteurs clés sont MatterPool Mining et leur écosystème Mattercloud: une joint-venture entre des acteurs indépendants de l'écosystème BSV, avec des connexions directes aux protocoles BoostPOW et 21e8 et des relations avec des développeurs BSV indépendants.
Bien sûr, il existe également des marques précieuses financées par Ayre. Il s'agit notamment de la propriété partielle via l'investissement dans HandCash, Centi, TonicPow et Planaria Corp de Unwriter.
Une autre mesure importante à prendre en compte est la distribution de la puissance de hachage (autre nom pour la puissance de calcul du résau). Alors qu'au tout début de BSV, les entreprises appartenant à Ayre représentaient une quantité importante de hachage sur bitcoin, afin d'assurer sa survie, BSV est aujourd'hui en grande partie exploité par des mineurs concurrents de Ayre tels que Binance, F2Pool, OKEX et ViaBTC - dont aucun n'est «ami» de BSV ou d'Ayre, mais beaucoup se déclarent les ennemis. Ces mineurs soulignent bien la nature ouverte et sans permission de BSV qui permet à quiconque de participer, notamment à ses ennemis!
Ayre est un acteur important, mais en aucun cas un contrôleur de la direction de la blockchain ou des entreprises indépendantes dans l'économie BSV.
Mais pourquoi Craig poursuit-il des gens en justice ?
Tout d'abord, et c'est crucial, le procès le plus important de Craig est l'affaire Kleiman. Les autres cas existent uniquement à cause de la diffamation publique du Dr Wright. Le hashtag #CraigWrightIsAFraud circule largement, poussé en grande partie par un mélange de personnages anonymes sur Twitter. Plus particulièrement Magnus Granath AKA «Hodlonaut» a été averti qu'une accusation publique de fraude courait à son encontre. La carrière du Dr Wright est en informatique et en criminalistique numérique, donc le déclarer publiquement une fraude sans preuve cause un préjudice financier au Dr Wright dans son domaine d'expertise commerciale. Puisque «Hodlnaut» a refusé de cesser, on lui a envoyer une requête pour être vu au tribunal afin de pouvoir apporter les preuves de ses accusations. Cela a causé le célèbre podcasteur de petits-blocs Peter McCormack à mendier d'être poursuivi aussi - en augmentant la rhétorique diffamatoire contre le Dr Wright. À la demande de McCormack, il a lui aussi été attaqué en justice pour être vu au tribunal. Le Dr Wright à depuis abandonné tous ses procès pour diffamation à l'exception de celui contre McCormack qu'il souhaite continuer pour faire exemple.
Cela a aussi engendré la campagne #DelistBSV menée en grande partie par «CZ», le PDG charismatique de Binance-Exchange. Divers autres échanges comme Shapeshift et Kraken ont publié des sondages twitter demandant s'ils devaient emboîter le pas, et des petits-blocs bien organisés ont voté en masse pour retirer BSV de leurs échanges - citant la toxicité du Dr Wright pour avoir intenté des poursuites en diffamation contre Hodlonaut et McCormack. Finalement, BSV a été retiré de Binance, ShapeShift et Kraken. Il a également été noté publiquement par Coinbase et Gemini qu'ils ne soutiendraient pas cette version de bitcoin à la suite de ce drame public. Il faut noter qu'après 2 ans, Binance a retourné sa veste et est aujourd'hui devenu un des principaux mineurs de BSV.
Au fur et à mesure que les choses progressaient, le fondateur de bitcoin .com, Roger Ver, a également réalisé une vidéo publique déclarant Wright comme arnaqueur. C'était après avoir travaillé sournoisement avec les développeurs Bitcoin ABC pour coder des points de contrôle dans le logiciel ABC de Bitcoin Cash, divisant de manière permanente le réseau Bitcoin pour la deuxième et dernière fois - un acte auquel le Dr Wright s'était opposé et pour lequel Roger est également poursuivi par d'autres parties privées en Floride. Roger Ver a été averti que s'il continuait, des poursuites juridiques similaires se présenteraient à sa porte pour avoir diffamé le Dr Wright, mais il à décidé de poursuivre les accusations publiques jusqu'à ce qu'il soit également entendu devant le tribunal pour fournir une preuve de la fraude de Wright, sous peine de sanctions pour diffamation publique. Aucune preuve n'a jamais été fournit, mais le Dr Wright a depuis abandonné ses poursuites contre Roger Ver pour se concentrer sur son procès avec Kleiman et celui avec McCormack ainsi que son travail sur Bitcoin.
Et maintenant que se passe-t-il ?
Nous avons établi l'histoire du Bitcoin, de sa guerre civile, des attaques publiques contre Wright, Ayre et BSV. Au moment d'écrire ces lignes, nous pouvons revenir sur les attaques contre Thomas Lee, Tim Draper et Jimmy Wales pour avoir eu une proximité avec BSV. Malgré la pression sociale, le rapport technique Fundstrat de Lee a rendu un examen élogieux du protocole fixe et de l'évolutivité infinie de BSV. Lee et son équipe étaient heureux de prendre la parole lors des événements précédents de CoinGeek, même après le tollé public.
Pour la conférence CoinGeek 2020 à New York, McCormack, Hodlonaut, « Arthur Van Pelt » et d'autres acteurs tels que le Dan Held de Kraken et une cacophonie de trolls anonymes sur Twitter ont mis à profit leur expérience de la culture d'annulation à la bolchevique pour faire pression sur l'orateur Gary Vaynerchuk ainsi que d'autres orateurs prévus pour cette conférence, afin de les forcer à annuler leur participation. Cette attaque sociale contre BSV, Dr. Wright, Ayre et les autres entreprises qui utilisent le réseau BSV pourrait être un gigantesque cas de fraude à la consommation. Ils trompent activement les gens en leur faisant croire que le protocole fixe et l'évolutivité infinie de Bitcoin BSV sont en quelque sorte dangereux, alors qu'en fait, le protocole et le réseau sont imperméables à toutes les attaques, à l'exception de leur ingénierie sociale.
Bitcoin SV s'est développé professionnellement avec un portefeuille de brevets de protection de niveau mondial. Il est utilisé par des entreprises indépendantes afin d'apporter des innovations technologiques et possède un groupe décentralisé de nœuds honnêtes qui se font concurrence. Le réseau est fixe, sécurisé et en croissance grâce aux investissements de petites entreprises et de gestionnaires de capitaux. Les transactions sont instantanées avec des frais de 0.0002€ par transaction en moyenne, explosant tous les records de compétitivité de l'écosystème et permettant aux plus pauvres de la planète d'enfin accéder à l'économie digitale mondiale. Les mensonges sont basés sur une campagne massive de dénigrement perpétrée par les communautés d'autres cryptomonnaies qui craignent l'adoption mondiale de BSV comme outil de commerce et ce que cela signifiera pour eux. L'histoire ne sera pas gentille avec ces manipulateurs et leurs réseaux qui sont financés par les fraudes probables des échanges de crypto-monnaies off-shore, le (très probablement) frauduleux Tether Stablecoin, et l'économie des arnaques de "pump-and-dump" qui sous-tend 95% du volume de négociation de l'ensemble de l'économie cryptomonnaie actuelle.
C'est une guerre civile. Il y aura toujours des victimes, mais alors que BTC et BCH se concentrent sur les ragots et les affaires illicites, BSV veut que le monde entier soit plus libre, plus souverain et plus capable de coopérer sur le registre mondial de la vérité afin que les entrepreneurs du monde puissent s'engager à créer des entreprises ou de simples nano-services sont rendus possibles uniquement par Bitcoin. Bitcoin est un test d'intelligence. Au fil du temps, les personnes intelligentes pourront voir à travers le brouillard de distorsion de la réalité créé pour confondre les innocents et reconnaître cela pour ce que c'est, une attaque coordonnée pour tenter de supprimer une technologie qui à un potentiel unique dans l'histoire, et qui les rendrait obsolètes.

Cryptarbitrage’s Deribit Spreadsheets Calculation Tools

Perpetuals, Futures, and Options can present quite a steep learning curve, fear not though as we have an incredible collection of Google Sheets and Excel Spreadsheets to help both the basic as well as most advanced users! We can also strongly recommend reading our Educational and Market Research articles as many traders find them to be invaluable resources.

One of our talented Community Managers, Cryptarbitrage, has created and maintains to the best of his ability a series of tools to both help Deribit users learn more about BTC & ETH Perpetuals, Futures, and Options as well support more advanced traders increasing technical needs.
A short introduction by Cryptarbitrage:
"Although I was aware of options beforehand I only started properly researching them in early 2018 after I discovered the Bitcoin options on Deribit. I do not need much encouragement to build a spreadsheet for something so quickly set about created an Excel sheet that would show me the profit and loss of any options position I entered.
This was a great way to learn all the profit and loss formulas for each type of option as well as how different option combinations interacted with each other. As soon as this sheet was complete I was building positions I still didn’t even know the proper names for so was very much learning by doing. It was immediately obvious to me though that options were the type of instruments I wanted to trade.
After a few months and once I’d done some more reading and was more confident I actually knew what I was talking about I began creating shareable versions in google sheets and sharing them with the Deribit community."

MCS | Shall we find financial freedom through Bitcoin Derivatives Trading?

MCS | Shall we find financial freedom through Bitcoin Derivatives Trading?
\This post has been written by Hedgehog, an MCS influencer and one of Korea's famous cryptocurrency key opinion leaders.*

https://preview.redd.it/652sev9bnjf51.png?width=1080&format=png&auto=webp&s=44eb34377752668e30cb5d6f156fe3ea5d091b89

#Be_a_Trader!

Greetings from MCS, the derivatives trading platform where traders ALWAYS come first.

The global gold price continues to rise. The gold price ended at $2049.30, up 1.4% ($28.30) per ounce for December delivery on the New York Mercantile Exchange on the 5th local time. For the first time in history, the gold price hit the $2,000 per ounce mark and settled to the $2,050 mark in a day. It is an unprecedented rise in gold price with an increase during 4 consecutive trading days and hit record highs 7 times in the last 8 trading days.
The cryptocurrency market also showed strong increases last night. As of 20:00 UTC, the bitcoin price was 11693.51 dollars, up 3.96% from the previous day, and Ethereum and Litecoin rose 3.17% and 3.29%, respectively. Also, Bitcoin dominance recorded 60.8%.
With the rise of international gold prices, traders around the world are naturally watching the bitcoin price. Today, we will share how you can realize profits through the trading of bitcoin derivatives, the perpetual contracts.

💡 "Bitcoin Derivatives Perpetual Contract Trading is a Trade of Contracts."
Understanding contract trading is the most difficult part for existing stock traders and traders who trade cryptocurrency spots when trading perpetual contracts. Let's take a closer look at the example of trading stocks and bitcoin derivatives below.

https://preview.redd.it/6xuv85sdnjf51.png?width=1280&format=png&auto=webp&s=81c2362ea79efd3f38ec0aef9b277b301c140b47
In the case of stocks, the money required to buy a stock of $5,000, you pay $5,000. If you buy one share of the stock for $5,000 and then sell the stock when the stock reaches $6,000, you realize a profit of $1,000.

https://preview.redd.it/v1nmsgqenjf51.png?width=1280&format=png&auto=webp&s=e8b763b72c527a8e422baa3f4c9e7c44b4245a91
As mentioned above, contracts are traded in the case of perpetual contracts. However, the value of each contract is roughly the same for each derivatives exchange. With MCS's BTC/USDT perpetual contracts as an example, 1 contract is worth 1 USDT.

💡 "1 Contract = 1 USDT? How do I trade that with Bitcoin?"
Assuming the price of bitcoin is 10,000 USDT, how many contracts can I buy on the BTC/USDT perpetual contracts with 1 BTC? As each bitcoin is worth 10,000 USDT, 10,000 contracts worth 1 USDT can be bought or sold.
So the question here, if the price of bitcoin is 20,000 USDT and I have 1 BTC, how many BTC/USDT perpetual contracts can I buy from MCS?
It would be 20,000 contracts. The easy way to figure this out is with this formula. "present value / contract value of bitcoin". In this formula, if the present value of bitcoin = 20,000 USDT and the contract value = 1 USDT, if substituted, it becomes 20,000/1 = 20,000 contracts.

💡 "Now I understand the concept of contracts, so how do I make profits??"
Bitcoin perpetual contracts have a long position that predicts the price increase and a short position predicting the price decrease. This revenue calculation part is well explained in the help center of MCS.

🎯 "You don't have to be excellent to start, but you have to start to be great." - Les Brown
If you are a trader who wants to realize economic freedom through cryptocurrency trading, I recommend the trading perpetual contracts on MCS. Firsts are always difficult and feels unfamiliar. However if you adapt and build up your know-how, it is like acquiring a new weapon that others do not have. If there are traders being lazy in learning due to the difficulty, MCS provides online customer support 24/7, so if you do not understand something, please get help from the MCS support team.

This is it from the margin trader Hedgehog.
*Bitcoin derivatives trading is a high-risk, high-return investment, so it is recommended to fully understand all related matters before trading.

Traders ALWAYS come first on MCS.
Thank you.

I've created bitmex BTC profit calculator with notifications.

I was struggling with multiple annoying calculators, ideas, different formulas and excel sheets... I needed something faster and easier, so yesterday morning I created this simple profit calculator for bitcoin.
Currently you can calculate multiple versions of profit for limit/market orders, you can also create notifications (plus button on bottom) that will popup when target is reached.You can also generate link via query params, so later I will make user script for it, that way people will be able to run it from trading platform, if such functionality will be needed/helpful.
Like lot of things I have made it for myself, however I decided that it may be useful for some of you.
Also I hope it will be not so annoying like rest of such apps.I hope I do not violate rules sharing it.
(no ads, no BS, only calculator + notifications)

A Glance at the Heart: Proof-of-Authority Technology in the UMI Network

A Glance at the Heart: Proof-of-Authority Technology in the UMI Network

https://preview.redd.it/vhvj6v093df51.jpg?width=1024&format=pjpg&auto=webp&s=00c0c223d9758edec8ed49a8cb9024f96d3ee343
Greetings from the UMI Team! Our Whitepaper describes in detail the key pros and cons of the two mechanisms which the great majority of other cryptocurrencies are based on:
Proof-of-Work (PoW) — mining technology. Used in Bitcoin, Ethereum, Litecoin, Monero, etc.
Proof-of-Stake (PoS) and its derivatives — forging technology. Used in Nxt, PeerCoin, NEO, PRIZM, etc.
As a result of a careful analysis of PoW and PoS, which are designed to fight against centralization, there came a conclusion that they both fail to perform their main mission and, in the long run, they lead to the network centralization and poor performance. For this reason, we took a different approach. We use Proof-of-Authority (PoA) algorithm coupled with master nodes, which can ensure the UMI network with decentralization and maximum speed.
The Whitepaper allows you to understand the obvious things. This article will give you a clear and detailed explanation of the technology implemented in the UMI network. Let's glance at the heart of the network right now.
Proof-of-Authority: How and Why It Emerged
It's been over a decade since the first transaction in the Bitcoin network. Over this time, the blockchain technology has undergone some qualitative changes. It's down to the fact that the cryptocurrency world seeing the emerging Proof-of-Work defects in the Bitcoin network year after year has actively searched for ways to eliminate them.
PoW decentralization and reliability has an underside of low capacity and scalability problem that prevents the network from rectifying this shortcoming. Moreover, with the growing popularity of Bitcoin, greed of miners who benefit from high fees resulting from the low network throughput has become a serious problem. Miners have also started to create pools making the network more and more centralized. The “human factor” that purposefully slowed down the network and undermined its security could never be eliminated. All this essentially limits the potential for using PoW-based cryptocurrencies on a bigger scale.
Since PoW upgrade ideas came to nothing, crypto community activists have suggested cardinally new solutions and started to develop other protocols. This is how the Proof-of-Stake technology emerged. However, it proved to be excellent in theory rather than in practice. Overall, PoS-based cryptocurrencies do demonstrate a higher capacity, but the difference is not as striking. Moreover, PoS could not fully solve the scalability issue.
In the hope that it could cope with the disaster plaguing all cryptocurrencies, the community came up with brand new algorithms based on alternative operating principles. One of them is the Proof-of-Authority technology. It was meant to be an effective alternative with a high capacity and a solution to the scalability problem. The idea of using PoA in cryptocurrencies was offered by Gavin Wood — a high-profile blockchain programmer and Ethereum co-founder.
Proof-of-Authority Major Features
PoA's major difference from PoW and PoS lies in the elimination of miner or forger races. Network users do not fight for the right to be the first to create a block and receive an award, as it happens with cryptocurrencies based on other technologies. In this case blockchain's operating principle is substantially different — Proof-of-Authority uses the “reputation system” and only allows trusted nodes to create blocks.
It solves the scalability problem allowing to considerably increase capacity and handle transactions almost instantly without wasting time on unnecessary calculations made by miners and forgers. Moreover, trusted nodes must meet the strict capacity requirements. This is one the main reasons why we have selected PoA since this is the only technology allowing to fully use super-fast nodes.
Due to these features, the Proof-of-Authority algorithm is seen as one of the most effective and promising options for bringing blockchain to various business sectors. For instance, its model perfectly fits the logistics and supply chain management sectors. As an outstanding example, PoA is effectively used by the Microsoft Azure cloud platform to offer various tools for bringing blockchain solutions to businesses.
How the UMI Network Gets Rid of the Defects and Incorporates the Benefits of Proof-of-Authority Method
Any system has both drawbacks and advantages — so does PoA. According to the original PoA model, each trusted node can create a block, while it is technically impossible for ordinary users to interfere with the system operation. This makes PoA-based cryptocurrencies a lot more centralized than those based on PoW or PoS. This has always been the main reason for criticizing the PoA technology.
We understood that only a completely decentralized product could translate our vision of a "hard-to-hit", secure and transparent monetary instrument into reality. Therefore, we started with upgrading its basic operating principle in order to create a product that will incorporate all the best features while eliminating the defects. What we’ve got is a decentralized PoA method. We will try to explain at the elementary level:
- We've divided the nodes in the UMI network into two types: master nodes and validator nodes.
- Only master nodes have the right to create blocks and confirm transactions. Among master node holders there's the UMI team and their trusted partners from across the world. Moreover, we deliberately keep some of our partners — those who hold master nodes — in secret in order to secure ourselves against potential negative influence, manipulation, and threats from third parties. This way we ensure maximum coherent and reliable system operation.
- However, since the core idea behind a decentralized cryptocurrency rules out any kind of trust, the blockchain is secured to prevent master nodes from harming the network in the event of sabotage or collusion. It might happen to Bitcoin or other PoW- or PoS-based cryptocurrencies if, for example, several large mining pools unite and perform a 51% attack. But it can’t happen to UMI. First, the worst that bad faith master node holders can do is to negligibly slow down the network. But the UMI network will automatically respond to it by banning such nodes. Thus, master nodes will prevent any partner from doing intentional harm to the network. Moreover, it will not be able to do this, even if most other partners support it. Nothing — not even quantum computers — will help hackers. Read our post "UMI Blockchain Six-Level Security" for more details.
- A validator node can be launched by any participant. Validator nodes maintain the network by verifying the correctness of blocks and excluding the possibility of fakes. In doing so they increase the overall network security and help master nodes carry out their functions. More importantly, those who hold validator nodes control those who hold master nodes and confirm that the latter don't violate anything and comply with the rules. You can find more details about validator nodes in the article we mentioned above.
- Finally, the network allows all interested users to launch light nodes (SPV), which enables viewing and sending transactions without having to download the blockchain and maintain the network. With light nodes, any network user can make sure if the system is operating properly and doesn't have to download the blockchain to do this.
- In addition, we are developing the ability to protect the network in case 100% of the master nodes (10,000 master nodes in total) are "disabled" for some reason. Even this is virtually impossible, we've thought ahead and in the worst-case scenario, the system will automatically move to PoS. By doing so, it will be able to continue processing transactions. We're going to tell you about this in our next publications.
Thus, the UMI network uses an upgraded version of this technology which possesses all its advantages with drawbacks eliminated. This model is truly decentralized and maximum secured.
Another major drawback of PoA-based cryptos is no possibility to grant incentives to users. PoA doesn't imply forging or mining which allow users to earn cryptocurrency while generating new coins. No reward for maintaining the network is the main reason why the crypto community is not interested in PoA. This is, of course, unfair. With this in mind, the UMI team has found the best solution — the unique staking smart-contract. It allows you to increase the number of your coins up to 40% per month even with no mining or forging meaning the human factor cannot have a negative impact on the decentralization and network performance.
New-Generation Proof-of-Authority
The UMI network uses an upgraded version of PoA technology which possesses all its advantages with drawbacks virtually eliminated. This makes UMI a decentralized, easily scalable, and yet the most secure, productive, profitable and fair cryptocurrency, working for the sake of all people.
The widespread use of UMI can change most aspects of society in different areas, including production, commerce, logistics, and all financial arrangements. We are just beginning this journey and thrilled to have you with us. Let's change the world together!
Best regards, UMI Team!

Plus que quelques mois avant notre FIRE

Bonjour à tous,
Je suis ravi de découvrir un sub francophone sur le FIRE !
Pour différentes raisons, autant structurelles que culturelles à mon avis, j’ai l’impression que nous ne sommes pas encore nombreux les Français à courir après cette indépendance. 🙂
Il y a quelques années mon épouse et moi avions décidé que nous procéderions à un changement radical de vie dès que nous pourrions financièrement nous le permettre. En toute honnêteté, nous n’avions à ce moment là pas encore entendu parler du mouvement FIRE et nous l’avons découvert il y a seulement deux ans. Je précise que nous avons tous les deux 45 ans et un enfant qui va entamer des études supérieures.
Nos objectifs étaient alors relativement simples : pouvoir abandonner nos carrières respectives (qui nous ont pleinement satisfaite, nous ne sommes pas du tout malheureux sur ce plan), et d’une manière plus générale n'avoir plus aucune dépendance vis à vis d’un quelconque employeur, pour retrouver une maîtrise totale de notre temps et pouvoir le consacrer à des projets beaucoup plus personnels. Parmi nos projets personnels, certains ont le potentiel de générer des revenus, mais nous souhaitions ne pas avoir de pression financière pour les réaliser et tout revenu généré serait pris comme un bonus.
Sauf erreur de calcul de notre part dans le Google Sheet qui héberge notre projet depuis quelques années, nous ne sommes maintenant plus qu’à quelques mois de notre FIRE. 2020 sera, sauf erreur ou accident, l’année de notre indépendance financière.
Notre stratégie se base sur des fondamentaux : 1) la constitution d’un capital, 2) une stratégie d’investissement pre-FIRE et une autre post-FIRE, 3) une diminution future du coût de notre vie sans sacrifice de notre niveau de vie actuel.
Nous sommes sur le point de terminer 1) par la constitution d’un capital de 800 K€ (une partie de ce capital finira de se concrétiser par des plus-values immobilières d’ici 2 à 3 ans, mais nous n’avons pas besoin d’attendre cela pour FIRE). C’est un capital construit de zéro et qui a été alimenté principalement par un salaire unique (mais élevé), par une belle opération en Bitcoin, et par une politique de défiscalisation immobilière qui nous a permis d’une part de mettre de l’argent de côté de manière plus agressive et d’autre part de faire des plus-values immobilières.
Concernant le point 2) nous sommes toujours en train de construire notre stratégie d’investissement car la structure de notre patrimoine va devoir considérablement évoluer pour la prochaine étape de notre projet. Nous avons encore quelques mois pour faire les premiers arbitrages.
Pour le point 3) nous avons déjà choisi notre solution depuis quelques années : l’expatriation dans un pays de l’Union Européenne avec lequel nous sommes très familiers et qui nous permettra de conserver notre niveau de vie actuel (qui est vraiment tout à fait standard) tout en réduisant nos besoins financiers de moitié. Nos besoins locaux oscilleront autour de 2 000 € / mois (ils sont actuellement d’un peu plus de 4 000 €). Et pour être un peu original, ce n’est pas le Portugal. 😉
Pour reprendre une terminologie FIRE, j'ai l'impression que cela nous situe quelque part entre lean FIRE et fat FIRE car nous ne sacrifions rien à ce qui fait notre bonheur matériel, mais nous n'avons pas non plus d'appétit pour le luxe. Notre définition personnelle du bonheur est juste de savoir que notre journée nous appartient, de profiter d'une pièce de vie cozy avec une cheminée pour lire au coin du feu (nous n'aimons pas les climats chauds), de beaux paysages à portée de nos jambes, pas de voisins et une bonne connexion Internet.
Nous avons un capital aujourd’hui très axé sur l’immobilier et nous allons le faire évoluer vers quelque chose de plus mixte avec une plus grande proportion exposée aux marchés actions ou trackers. Et même si la réalité pourra nous donner tort, nous sommes partis du principe que nous ne toucherons aucune retraite, tout en ayant cotisé plus de vingt ans en tant que salarié (et donc potentiellement à perte).
Nous ne sommes pas encore au bout du chemin, mais nous ne voyons plus beaucoup d’obstacles sur la route et nous sommes plus motivés que jamais !
Voilà pour notre témoignage. N’hésitez pas si vous avez des questions, ou si vous souhaitez challenger notre stratégie car nous n’avons bien sûr aucune certitude sur nos choix. Notre futur est aujourd’hui encore contenu dans un tableur, et nous savons tous que Excel et Google Sheets sont les plus puissants logiciels de réalité virtuelle au monde. 😉

License to Kill – Bond(s) explained

The below is the text from my latest blog post about bonds, if you want to see the original with pretty pictures, charts, graphs etc then click on this link.
Ok, the title is an obvious dad joke, but as it happens it still fits in with my naming convention for posts so happy days! On to more serious stuff.
The most common proposed asset allocation for people pursuing FIRE seems to involve having absolutely as much invested in equities (or to a lesser extent property) as possible, and reducing every other asset class to as little as possible. Which is certainly one way of doing things, and given the great performance of shares and property over the last 20 years or more there is an argument to be made for doing things this way.
It’s certainly not the only way of doing things though, and I will be trying to show why there is a case to be made for investing some money in other asset classes, in particular Fixed Income aka Bonds.
So what are bonds?
Bonds are a type of debt that is issued by governments, semi-government organisations, and corporations, so basically you’re lending them money. In Australia we also have what are called hybrid securities, but they’ve got some big enough differences that I’ll talk about them in a future post (probably).
Bonds are also one of those fun areas where there is an exception to every rule, so although what I’ve written below is broadly accurate there is always going to be some type of bond or a specific issue that breaks one of the rules.
So please don’t be an internet hero and “well ackshually” me about premium redemption/issue bonds, soft calls, hard calls, investor puts, floaters, PIK notes and all the rest of it because broadly speaking it isn’t going to make much difference for the purposes of explaining bonds. Basically play nice readers!
Talk numbers to me…
Bonds are all about math. As I’m sure regular readers of this blog can imagine this makes me very happy, and probably explains in part why I spent a large part of my career working in an area where understanding bonds was crucial, although to make things more interesting we added on a bunch of other stuff like equity options, credit derivatives, FX etc.
The main numbers to think about are the price you paid for the bond, the coupon on the bond, the yield on the bond, the time to maturity, and the maturity value of the bond. From those main numbers we also derive a bunch of other numbers I’ll talk about later.
Bonds are normally issued at a price of 100, with a fixed coupon (interest payment based on the maturity value of the bond) and a fixed maturity value at a known maturity date. So that’s 4 of the numbers covered already, happy days!
A lot of the time though you’re not going to be buying that bond when it is issued, you’ve buying it when it’s already trading in which case chances are pretty good you didn’t pay 100 for the bond. Buying it along the way doesn’t affect the coupon or the redemption amount at maturity or when it matures.
What it does affect though is the yield. There are a bunch of different yield measures but I’m going to go with yield to maturity, ie what yield (return) will you get if you hold the bond to maturity.
It’s not a perfect analogy, but one way to think about bonds is that they’re like a term deposit where the amount that you can buy it for moves around. If you buy a bond for $10,000 that is going to mature in a year and it has a 2% coupon and redeems for $10,200 (redemption price plus coupon payment), then your yield (2%) is the same as your coupon (2%).
But if interest rates have changed and so the price of the bond has changed and you buy that bond for $9,900 or $10,100, then your yield will be different from your coupon, either 3% or 1% respectively. Hopefully that makes sense? BTW I’ve rounded the numbers here to try and keep it nice and simple.
Most bonds pay interest on a semi annual basis (I used an annual payment in the example above to make things easier) so to figure out how much interest you get when it gets paid it’ll be the coupon divided by two.
Hopefully all of that makes sense, if not let me know in the comments.
Issuers of Bonds
As I said above the main issuers of bonds are governments, semi government organisations, and corporations.
Debt issued by governments is generally the safest type, because so long as they control the printing press then they can always print more money to pay you back. The Eurozone is a bit of an exception to this (understatement of the year) but in most of the other major sovereign bond markets like the US, Australian, the UK etc it’s true.
Emerging markets are a bit different because they often issue debt in USD, which means that if things go pear shaped then they can’t just print more money to pay off bondholders.
There can also be issues with getting your money back from sovereigns if they have too much debt, such as when they either don’t control the printing press (Greece) or the bond is issued in a different currency (Argentina) but for the most part if you lend money to a developed country in their own currency then you can pretty reliably count on getting your money back.
There are also bonds issued by semi government organisations like the World Bank, European Bank for Reconstruction and Development etc, these are slightly less safe for the most part but you’re still not taking on much risk of not getting your money back.
Debt issued by corporations is riskier, partly because businesses obviously can’t just print more money to pay you back, and because corporations can and do go bust. Sure it doesn’t seem likely that Telstra or Woolworths or the big banks are going to blow up any time soon, but there are plenty of other bond issuers out there with much more fragile finances.
As you would expect the more risk you are taking on the more return you want in order to be compensation for doing so. This is because unlike a term deposit the value of your capital isn’t protected. If you put $10,000 into a term deposit for a year with an interest rate of 2%, then you know that in a year’s time you will get back that $10,000 plus $200 in interest.
If for some reason the bank you invested that money through goes bust, the government will make you whole (up to the value of $250,000 per entity per approved deposit institution.
If you invest in a corporate bond and the company goes bust, well you’re probably not going to get all or maybe any of your money back. The good news is that you’re more likely to get money back than equity holders, but if the debts of the company are a lot more than the assets then you’re going to be in trouble.
There’s a clear framework for what happens if a company goes bust and who gets paid first and in how much etc, the short version of this is that equity holders are absolutely last in line but depending on what type of bonds you own you may not be a meaningful better position either.
And unlike a stock, when you own a bond you don’t own a piece of the issuer of the bond, you just own part of their devt. So if the company does great and starts making a fortune, you as a bondholder don’t get paid any more than what the terms of the bond state. Basically you can get a fair chunk of the downside and none of the upside beyond the terms of the bond. On the plus side this doesn’t happen particularly often, most of the time you’ll get what you were promised
Bond ratings
Now obviously some companies are more secure and stable than others. If you take a bond from the biggest company in the ASX200 which is CBA, then it’s more likely to fulfil the terms of the bond than whatever the 200th company is. That’s not to say the 200th company won’t, just that there is more risk. The actual degree of this risk is quantified in a couple of different ways.
First of all there are ratings agencies out there who will assign a rating from anywhere to super safe (AAA) to D (in default) with a bunch of graduations in between. Anything rated from AAA to BBB- is what is called Investment Grade (IG), everything below that is called High Yield (HY) or less politely Junk.
Just because a bond is IG doesn’t guarantee it will pay off, likewise something which is HY isn’t guaranteed or even likely to fail. For the most part though the different ratings given tend to play out that way in the real world, with far less defaults for bonds rated AAA vs bonds rated BB for example.
The big three ratings agencies are Standard & Poors (S&P), Moodys, and Fitch, and between them they’ll rate most of the bonds and/or issuers. They tend to be fairly backward looking in my opinion, and they were hugely and obviously wrong on rating mortgage backed securities back in the GFC. Still, they will generally give you a reasonable idea of the creditworthiness of the bond issuer.
Because bonds are also traded in the marketplace you can take the yield offered on a bond with a particular maturity, compare it to an equivalent government bond, and using some fun math (yeah baby!) back out a credit spread which that bond trades over treasuries (or swaps but I’m not going to get into that). The higher the spread, the higher the perceived risk of the bond, and vice versa of course.
Are bonds safe?
Well it kinda depends on what you mean by safe. If you mean are the bonds likely to deliver what the issuer of the bonds promised, then generally yes. As I said with government and semi government bonds you will almost certainly get all your coupons and the maturity value of the bonds delivered on time. Yeah, there are some exceptions to this but you’re unlikely to run into trouble with Australia, the US, the UK, the more economically sensible members of the Eurozone etc.
Similarly with corporates the vaast majority of the time you will get your money back on investment grade bonds, and it’s pretty rare to not get your money back on high yield bonds as well. That’s not to say it doesn’t happen, but it doesn’t happen much.
If you mean am I going to get back what I put into the bond, well no they’re not necessarily safe, particularly if you sell before maturity. Remember when I said bonds are kinda like term deposits that can trade? Well when they trade those prices move around, and they can move around a lot!
Why do bond prices move?
There are a bunch of reasons why bond prices move around, the main ones are changes in the interest rate environment, changes in economic conditions, and changes specific to the issuer of the bond.
We’ll talk about interest rates first. Bond prices have an inverse relationship with bond yields, which is a fancy way of saying if interest rates (yields) go down then bond prices go up.
How much do they go up? Well that depends on the magnitude of the change in rates, and a bunch of factors involving the bond. Basically the longer till maturity on the bond, and the lower the coupon on the bond, the more sensitive it will be to changes in interest rates. This is measured using modified duration and convexity.
Modified duration takes into account the timing of the cashflows of the bond (so coupons and maturity) and gives you a number which is typically a little less than that number of years to maturity, the higher the coupon the more it decreases the modified duration. If you multiply that modified duration by the change in interest rates in percentage terms, it will tell you how much the bond price will move by (in theory at least).
So if you have a modified duration of say 7.117, then for every 1 percent move in interest rates the bond price will change by 7.117 points. So if your bond price was previously 100 and rates moved down by 1%, then your bond should now be worth 107.117. Happy days! Conversely if rates moved up, well your bond is now worth 92.883. Not so happy days.
I’ve used the [ASX bond calculator](http://%20https//www.asx.com.au/asx/research/bondCalculator.do) to give a couple of examples using the current Aussie 10 year bond. You can hopefully see below that by changing the yield on the bond from 1.5% to 1% the market price has gone from 116.87 to 121.83, roughly a 4.25% change in price for a 0.5% change in rates, so presumably the modified duration on the bond is about 8.5.
To make things slightly more complex, that relationship isn’t fixed due to something called convexity. Instead of being a linear relationship, it’s actually a changing one (a curve rather than a line). Basically the more bonds prices move away from where they were issued the more that relationship will change.
Then there are things like GDP numbers, employment numbers, consumer sentiment surveys, PMI surverys, and all sorts of other economic news which will potentially move bond yields around, generally pretty slightly but it really depends on how important that economic number is and how much of a change from expectations it is.
On top of that for corporations changes in their own situations will have an effect on what their credit rating/spread is which will affect prices as well. If a company goes from being loss making to suddenly making a profit, then that’s going to be good for their credit and the bond price is likely to go up. Bad news like a profit warning will potentially mean a higher credit spread and lower price for the bond.
There is also general investor appetite for risk, so if investors are happy to take on more risk in their asset allocation (risk on) then they will likely sell off lower risk assets like bonds and buy higher risk assets like equities and to a lesser extent property. If things change and they want to go risk off, then the reverse happens and money tends to come out of equities and into bonds.
What happens to bonds if the stock market crashes or we have another GFC?
A stock market crash is actually one of the more compelling reasons to invest in bonds. This is because when stock markets crash investors tend to put their money into asset classes where they feel a lot safer ie, bonds. The rationale is that getting your money back is now hugely important, and even more important is not losing all your money as you will in those horrible equities which you knew you should never have invested in but that horrible financial adviser talked you into.
People. Are. Not. Rational. People panic. People sell assets which are going down in value even though they know they should be holding on for the long term. This applies not just to retail investors, but also to professionals who should know better.
In the GFC I spent plenty of time talking to institutional investors with a long term time horizon (ie 5 or 10 years etc) who suddenly decided they had to get out because of bad one month performance. People will bail out if the proverbial is hitting the fan. I wrote a bit about my experiences with the GFC here, and believe me there are a lot of people who are not going to be as cool calm and collected as they think they will be.
It’s very very very very (extra very for emphasis) important to note here that at this point in time investors will not be thinking that all bonds are much the same. When they are looking for somewhere to put their money that they now have after panic selling out of equities, they will park it in the safest place they can find, ie government bonds (aka treasuries). This will cause the price of those bonds to rise because of supply and demand.
If they still want to take on some amount of risk then they might put some into investment grade bonds, again this will push the price up a bit. They will almost certainly not put money into high yield bonds, because those are risky and in a crisis will behave pretty similarly to equities, ie they will fall in value. If anything they will more than likely try to pull money out of HY bonds, pushing the price down.
This excellent post really shows this in the below graph which shows the average performance of different types of bonds for a 10% or greater fall in the stock market (all of this is for the US but the same principle applies to Australia).
It doesn’t work in every case, as shown below (same source), but in almost all cases of a big crash in equities, treasury and to a lesser extent IG bonds gave you a big positive return to help out. HY, not so much and in some cases actually gave you a worse performance than equities themselves.
Please believe me when I say it is a huge help psychologically to have some of your investments going up when the others are going down, which to me at least is a great reason to have some money invested in bonds.
You’ve convinced me, how much should I have in bonds?
Ok so I’m probably being slightly optimistic here given the number of posts I see on reddit about how VDHG would be so much better if Vanguard got rid of that terrible 10% that’s invested in bonds and put it all in equities instead.
It would be nice to think though that some people are now realising that come the next crash they too might not behave entirely rationally, and it sure would be nice to own some assets that are going to zig when the stock market zags, so to speak.
On the off chance that I have actually convinced people, well it really comes down to your particular risk profile. This is going to be hard to believe for some people, but in the US the default portfolio for most investors is 60% stocks and 40% bonds.
Looking at Oz , the default balanced investment option for most super funds over here are supposed to have something like a 70:30 split between growth assets (shares and property) and defensive assets (bonds and cash) although the reality is a long long way from that if you actually look into how they invest (that’s a discussion for another time though). So that maybe provides a useful starting point.
I know that the average FIRE portfolio that gets talked about particularly from younger bloggers (who have likely never experienced a sustained down market) is pretty much 100% equities and property, maybe even leveraged up. Which is fine if you can hold on through the downturns, but not everyone can do this because it is extremely difficult to do psychologically. I wish them all the best of luck, but I am pretty sure that at least some of them will decide that it’s all too much and sell whenever we have the next crash.
There are exceptions to the rule though. One of my favourite bloggers, and someone who I know thinks deeply about this sort of stuff, is the FI Explorer who has about 15% in bonds and 15% in defensive alternatives (gold and bitcoin) as per his latest portfolio update.
Whilst I don’t like Bitcoin myself, or gold for that matter, he writes a good explanation about why he holds both here. I still don’t like either asset myself, but I recognise that I am not infallible, I could well be wrong about this, and certainly historically they have worked well as hedges.
In any case the more important point here is that there is basically a 30% allocation to what would be regarded as defensive type assets. This is actually a bit over his actual target of 25% in defensive assets, but he probably sleeps just fine at night.
I’m a little more aggressive in only having about 21% of my assets (excluding PPoR) in cash and bonds, but it’s not a huge difference. Both of us have been invested through stock market crashes and hopefully have come to realise that we are not the hyper rational investors that economists believe we are, and therefore it’s best to have a bit invested in stuff that will go up or at least hold it’s value when everything else is crashing.
How do I buy bonds?
You can buy bonds individually, but you tend to need to have a fair amount of money to do so and you can run into a lot of problems with liquidity, big bid/ask spreads etc, it’s hard to build up a diversified portfolio etc.
I buy bonds the same way I buy stocks, ie via an ETF. Most of the major ETF providers have some variety of index ETFs tracking Treasury only or Treasury plus Investment Grade bonds, or you can buy HY stuff if you want. Personally I just use one ETF which has about 75% in treasuries and the rest in IG. There are also some actively managed bond funds out there, either as ETFs or managed funds.
For the reasons I outlined above about bonds being a psychological safe harbour I personally would (and do) only invest in bonds which are likely to up in a crisis, but different strokes for different folks applies as always.
Any more questions?
I’ve only really scratched the surface here of talking about bonds, but at the same time I feel like it’s an overwhelming amount of information. If you have more questions then as always I’m happy to answer them in the comments!
