4 stars based on 31 reviews

Announcing World Trade Francs: The Official Ethereum Stablecoin 01st April, Ethereum scalability research and development subsidy programs 02nd January, Thanks to all the developers and team leads who contributed to the sections on their projects.

In the last month and a half, the Ethereum network went through a rapid ethereum blog searching in usage, to the point that it now processes as many transactions per second as Bitcoin. The pyethereum client has seen a substantial revamp, and version 2.

Additionally, we have implemented experimental versions of: Metropolis testing is rapidly moving forward. We are actively seeking additional help with finishing testing. We have started a substantial cross-client benchmarking effort to identify places that are in greatest need of performance improvement. Ethereum blog searching some preliminary results for opcode benchmaking in geth here: Ethereum core developer meetings 19 took place.

In May-June, the Mist team had a team meetup: While we have a long list of features we are working on, we ethereum blog searching that most ethereum blog searching the issues reported on github were related to two main issues: We outlined features that we could implement to help prevent user errors and other related issues, including more options for node switching including Infura support and better options for account management including HD wallets and mnemonic seeds ethereum blog searching but with a twist.

The new whisper API was recently added to the old 0. Whisper v5 is currently only available in geth and needs to be started using —shh. We are currently adding swarm. If everything goes well, an alpha release will happen soon. You can ethereum blog searching test the new web3. We have received several bounty submissions for vulnerabilities in EthereumJS, Solidity and Cpp-ethereum. See the leaderboard for the current stats. We now have pyethereum on board on the cross-client blackbox consensus testing in Hive, which continuously performs over 10K tests on each client.

In preparation for Metropolis, a benchmarking suite for the Geth EVM has been implemented to ensure that the gas prices for new opcodes and precompiles are within reasonable bounds, so as to not constitute DoS-vectors at a later point. Discussion and critique are welcome at the https: The ethereumJS team is still looking for community contributors to help the Ethereum Javascript client reach Metropolis compatibility.

New algorithms have been designed and implemented in order to improve log searching performance in the next version of the LES protocol. We have put some efforts into finalizing the ethereum blog searching discovery protocol, which helps clients to find suitable LES servers as it is currently a somewhat weak point in the experimental light client ethereum blog searching.

The main Remix feature in the last month is the alpha release of Remixd: The progress in the eth-isabelle project was mostly from external contributions. The Solidity project has been quite active in the last months, although most of the updates is not yet directly visible on the user side.

We saw a lot more engagement by the community and now have volunteers regularly contributing both to the core code as well documentation including translation, mainly into Spanish. We added a feature that allows export of the full abstract syntax tree with all type annotations, which makes it much easier to write tools that would otherwise need a custom-made parser.

Ethereum blog searching next feature will be to also re-import this data after potential modifications, which would allow things like mutation testing. We extended the inline assembly language with structured elements for, switch and functions and deprecated manual jumps. This new inline assembly language will become a new intermediate ethereum blog searching together with type ethereum blog searchingwhich allows Solidity to ethereum blog searching more transparent in its compilation, more efficient we will be able to add much more sophisticated optimizer routines and more portable it can already compile to EVM, EVM1.

We are currently rewriting the ABI encoder in this intermediate language which will include structs and nested dynamic objects. Finally, we are adding an automated compile-time overflow and assertion checker which will also feature an SMT solver for the more complicated cases.

Oh and of course, we ethereum blog searching worked on tons of bugfixes and smaller features. The swarm team has onboarded new members and held an in-person Swarm Summit in Berlin in June, The week-long event brought together Ethereum team members, community contributors andspecial guests representing projects and companies interested in swarm.

More than twenty talks and tutorial sessions were recorded. The edited videos will be published soon on the swarm summit website. Our public alpha test saw a great community response allowing us to gather more information on prospective user base needs and what the typical usage patterns might be. The high churn of nodes requires an explicit distinction between nodes that can and cannot commit to being available for a longer period of time to provide sufficient storage and bandwidth resources for the network.

To support noncommiting nodes and mobile clients, swarm will offer various light modes of operation. We have developed a suite of example applications highlighting the architectural and implementational peculiarities of Swarm-hosted distributed web applications that are quite a departure from the traditional client-server model.

In particular, the building blocks of a distributed functional equivalent of dropbox are being developed, such as a web-interface providing a file-system view of swarm-hosted volumes, ENS integration, Mist-integration, FUSE mounting of swarm-volumes and privacy protections. We added a new protocol, pss bzz whispered allowing ethereum blog searching messaging ethereum blog searching deterministic routing based on the relaying kademlia network topology of swarm. The protocol uses whisper envelopes and offers udp-like protocol communication between nodes that are not directly connected.

This framework includes both scripting and visualization capabilities. Ethereum blog searching cooperation with the Remix team, the implementation of a fully distributed integrated contract development environment is underway. The next major release, POC 0.

Announcing World Trade Francs: The Official Ethereum Stablecoin 01st April, Ethereum scalability research and development subsidy programs 02nd January, Special thanks to Robert Sams for the development of Seignorage Shares and insights regarding how to correctly value volatile coins in multi-currency systems. Results of this research will likely go into either subcurrencies or independent blockchains.

One of the main problems with Bitcoin for ordinary users is that, while the network may be a great way of sending payments, with lower transaction costs, much more expansive global reach, and a very high level of censorship resistance, Bitcoin the currency is a very volatile means of storing value. Seeing this concern, there is a growing interest in a simple question: Can we have the full decentralization that a cryptographic payment network offers, but at the same time have a higher level of price stability, without such extreme upward and downward swings?

However, the problem of making a price-stable cryptocurrency, as the researchers realized, is much different from that of simply setting up an inflation target for a central bank. The underlying question is more difficult: To resolve the issue properly, it is best to break it down into two mostly separate sub-problems:.

For the decentralized measurement problem, there are two known major classes of solutions: As far as exogenous solutions go, so far the only reliable known class of mechanisms for possibly cryptoeconomically securely determining the value of an exogenous variable are the different variants of Schellingcoin — essentially, have everyone vote on what the result is using some set chosen randomly based on mining power or stake in some currency to prevent sybil attacks , and reward everyone that provides a result that is close to the majority consensus.

If you assume that everyone else will provide accurate information, then it is in your interest to provide accurate information in order to be closer to the consensus — a self-reinforcing mechanism much like cryptocurrency consensus itself. Particularly, what if some medium-sized actor pre-announces some alternative value to the truth that would be beneficial for most actors to adopt, and the actors manage to coordinate on switching over?

If there was a large incentive, and if the pool of users was relatively centralized, it might not be too difficult to coordinate on switching over. Now, if there are two kinds of mining, one of which is used to select Schellingcoin participants and the other to receive a variable reward, then this objection no longer applies, and multi-currency systems can also get around the problem.

However, we should not simply count on this incentive to outweigh 1. The second block time would mean that there is almost no time for coordination. The creator of the block can be strongly incentivized or even, if the Schellingcoin is an independent blockchain, required to include all participations, to discourage or prevent the block maker from picking and choosing answers.

A fourth class of options involves some secret sharing or secure multiparty computation mechanism, using a collection of nodes, themselves selected by stake perhaps even the participants themselves , as a sort of decentralized substitute for a centralized server solution, with all the privacy that such an approach entails.

The incentive to vote correctly is that only tests that remain in the main chain after some number of blocks are rewarded, and future voters will note attach their vote to a vote that is incorrect fearing that if they do voters after them will reject their vote. If Schellingcoin proves unworkable, then we will have to make do with the other kinds of strategies: Examples of such services include:.

A slightly different, but related, strategy, is to measure some statistic that correllates indirectly with price, usually a metric of the level of usage; one example of this is transaction volume. The problem with all of these services is, however, that none of them are very robust against rapid changes due to technological innovation.

Hence, trying to peg a currency to any of those variables will likely lead to a system which is hyperinflationary, and so we need some more advanced strategies for using these variables to determine a more stable metric of the price.

First, let us set up the problem. Formally, we define an estimator to be a function which receives a data feed of some input variable eg. Unfortunately, the problem with this approach is obvious from the graph and was already mentioned above: Note that there are an infinite number of versions of this estimator, one for each depreciation rate, and all of the other estimators that we show here will also have parameters.

The optimal value for the compensated estimator is a drop of 0. The next estimator that we will explore is the bounded estimator. The way the bounded estimator works is somewhat more complicated. Any growth outside these bounds it assumes is coming from price rises or drops.

The theory is that cryptocurrency price growth to a large extent happens in rapid bubbles, and thus the bounded estimator should be able to capture the bulk of the price growth during such events. There are more advanced strategies as well; the best strategies should take into account the fact that ASIC farms take time to set up, and also follow a hysteresis effect: A simple approach is looking at the rate of increase of the difficulty, and not just the difficulty itself, or even using a linear regression analysis to project difficulty 90 days into the future.

Here is a chart containing the above estimators, plus a few others, compared to the actual price:. Note that the chart also includes three estimators that use statistics other than Bitcoin mining: We can also split up the mining-based estimators from the other estimators:.

Of course, this is only the beginning of endogenous price estimator theory; a more thorough analysis involving dozens of cryptocurrencies will likely go much further. The best estimators may well end up using a combination of different measures; seeing how the difficulty-based estimators overshot the price in and the transaction-based estimators undershot the price, the two combined could end up being substantially more accurate.

Something like Bitcoin, if it becomes mainstream, will likely be somewhat more unstable than gold , but not that much more unstable — the only difference between BTC and gold is that the supply of gold can actually increase as the price goes higher since more can be mined if miners are willing to pay higher costs, so there is an implicit dampening effect, but the supply elasticity of gold is surprisingly not that high ; production barely increased at all during the run-ups in price during the s and s.

The price of gold stayed within a range of 4. The other issue that all of these estimators have to contend with is exploitability: Mining difficulty, however, is much more difficult to exploit simply because the market is so large. If a platform does not want to accept the inefficiencies of wasteful proof of work, an alternative is to build in a market for other resources, such as storage, instead; Filecoin and Permacoin are two efforts that attempt to use a decentralized file storage market as a consensus mechanism, and the same market could easily be dual-purposed to serve as an estimator.

The simplest approach is to simply issue them as a mining reward, as proposed by the Japanese researchers. However, this has two problems:. If not handled very carefully, the second problem has the potential to create some rather dangerous feedback loops in either direction; however, if we use a different market as an estimator and as an issuance model then this will not be a problem.

The first problem seems serious; in fact, one can interpret it as saying that any currency using this model will always be strictly worse than Bitcoin, because Bitcoin will eventually have an issuance rate of zero and a currency using this mechanism will have an issuance rate always above zero. Hence, the currency will always be more inflationary, and thus less attractive to hold. However, this argument is not quite true; the reason is that when a user purchases units of the stabilized currency then they have more confidence that at the time of purchase the units are not already overvalued and therefore will soon decline.

Alternatively, one can note that extremely large swings in price are justified by changing estimations of the probability the currency will become thousands of times more expensive; clipping off this possibility will reduce the upward and downward extent of these swings.

For users who care about stability, this risk reduction may well outweigh the increased general long-term supply inflation. This approach can be described as follows:. Because stable-coins are a zero-total-supply currency ie. However, the mechanism has some rather serious fragility properties. At the end, the stable-coin could easily end up being worth nothing at all. Note that BitShares has now moved to a somewhat different model involving price feeds provided by the delegates participants in the consensus algorithm of the system; hence the fragility risks are likely substantially lower now.

An approach vaguely similar to BitAssets that arguably works much better is the SchellingDollar called that way because it was originally intended to work with the SchellingCoin price detection mechanism, but it can also be used with endogenous estimators , defined as follows:.

Note that there are still fragility risks here. Second, if the vol-coin market is too thin, then it will be easily manipulable, allowing attackers to trigger margin call cascades. Another concern is, why would vol-coins be valuable? Scarcity alone will not provide much value, since vol-coins are inferior to stable-coins for transactional purposes. Now, consider a strategy where a user tries to hold on to a constant percentage of all vol-coins.

Seignorage shares is a rather elegant scheme that, in my own simplified take on the scheme, works as follows:. However, the simplicity comes at the cost of some degree of fragility. To see why, let us make a similar valuation analysis for vol-coins. The profit and loss scenarios are simple:.

The same valuation strategy applies as in the other case, so we can see that the value of the vol-coins is proportional to the expected total future increase in the supply of stable-coins, adjusted by some discounting factor.

Thus, here lies the problem: In exchange for this fragility risk, however, vol-coins can achieve a much higher valuation, so the scheme is much more attractive to cryptoplatform developers looking to earn revenue via a token sale. Note that both the SchellingDollar and seignorage shares, if they are on an independent network, also need to take into account transaction fees and consensus costs.

Fortunately, with proof of stake, it should be possible to make consensus cheaper than transaction fees, in which case the difference can be added to profits. Ultimately, however, some degree of fragility is inevitable: Even sidechains, as a scheme for preserving one currency across multiple networks, are susceptible to this problem. The question is simply 1 how do we minimize the risks, and 2 given that risks exist, how do we present the system to users so that they do not become overly dependent on something that could break?

Are stable-value assets necessary? There would then be multiple separate classes of cryptoassets: If that were to happen, and particularly if the stronger version of price stability based on Schellingcoin strategies could take off, the cryptocurrency landscape may end up in an interesting situation: The true cryptoeconomy of the future may have not even begun to take shape.

On a related note: It came from the thought experiment: How do we value them? Having thousands of paired currencies with low volumes are unfeasible. Something that sets cryptocurrencies apart from fiat, is that one can prove how long money has been held dormant.

This is based on the assumption that the more valuable and useful a blockchain is, the more it gets used which might not be an entirely right assumption. If a cryptocurrency is used often, you will see that kinetic days as a percentage of all time in the blockchain would be lower than less successful blockchains.

However, this is not reasonable. But theoretically, a ratio can exist which compares a blockchain to this ideal.

It would then result in something like saying: The hopefully emergent factor from measuring their value in terms of time, is that creates a new unit of account: As you can see. Nice overiew of existing methods. But they may have very less to do with the actual trading price on an exchange. Is it still true, that the value of something is the amount of money someone is willing to pay for it. If a Dapp developer desperatly needs Ethers for his Dapp, and the miners wont let go of their Ether, speculating that Ether will gain in value, the price will increase regardless of above mentioned techniques.
