DevCon 1 will be happening in London on November 9-13, a little over one hundred days since the Ethereum network launched. Over the last months, we’ve seen the network grow from a few hundred nodes starting on that one exciting and special night to a very substantial, globally deployed stable platform with thousands of devs pushing towards the decentralization revolution which motivates and inspires us. DevCon will have three primary categories of topics: Basic research and core protocols: including proof of stake, scalability, networking protocols, privacy and zero-knowledge proofs, as well as some of the more mathematical aspects of decentralized…
The following are some interesting results on the performance of different miners over the course of the first 280,000 blocks of the Ethereum blockchain. For this timespan I have collected the list of block and uncle coinbase addresses; raw data can be found here for blocks and here for uncles, and from this we can glean a lot of interesting information particularly about stale rates and how well-connected the different miners and pools are. First off, the scatter plot: What we clearly see here are a few primary trends. First of all, uncle rates are quite low compared to Olympic;…
Many of you know that the Ethereum platform grew out of the realization that blockchains can go far beyond currency, together with a frustration with the limitations of previous projects. The core idea was simple: a blockchain with a built-in Turing-complete programming language, allowing users to build any kind of applications on top. Over time, the vision evolved and expanded. The blockchain remains a crucial centerpiece, but it is ultimately only part of a larger vision of “web 3.0” as described by Gavin Wood here: a more secure, trustworthy and globally accessible internet for agreements, finance, auditing, tracking and simple…

In an effort to bring the community more information about the going-ons at Ethereum, we’re planning to release semi-weekly updates of project progress. I hope this provides some high-level information without having to live on GitHub 😉 The Go and C++ teams have daily standups and are making regular progress along with several other improvements around the ecosystem. Concurrent with this, the teams are gearing up for DEVCON1, preparing talks and presentations along with finalizing more details in the coming weeks. If you haven’t already registered, visit https://devcon.ethereum.org/ to join the fun next month in London. Now on to the updates… Mist Hoping…
Over the last five days, myself, our executive director Ming Chan, and several others from the Ethereum team and Ethereum-based projects and businesses including Maker, String/Dfinity and Consensys have been visiting China and Hong Kong, where there have been a series of back-to-back conferences and events most notably including the Blockchain Workshop in Hong Kong on Oct 11-13 and the “First Global Blockchain Summit” in Shanghai organized by our friends at Wanxiang on Oct 15-16, while at the same time continuing to work on our usual tasks of research, development, planning DEVcon and administrative matters. Both conferences proved to be,…
Summary: Erroneous implementation of BLOCKHASH can trigger a chain reorganisation leading to consensus problems Affected configurations: All geth versions up to 1.1.3 and 1.2.2. All eth versions prior to 1.0.0. Likelihood: Low Severity: Medium Impact: Medium Details: Both C++ (eth) and Go (geth) clients have an erroneous implementation of an edge case in the Ethereum virtual machine, specifically which chain the BLOCKHASH instruction uses for retrieving a block hash. This edge case is very unlikely to happen on a live network as it would only be triggered in certain types of chain reorganisations (a contract executing BLOCKHASH(N – 1) where…
London, United Kingdom, October 22nd – The Ethereum Foundation is pleased to announce the Keynote Speaker of Ethereum’s annual conference DΞVCON1, Nick Szabo. Nick’s keynote will focus on the history of the blockchain, smart contracts and assets on the blockchain. Nick is a computer scientist, legal scholar and cryptographer known for his research on digital contracts and digital currency. The phrase and concept of “smart contracts” was developed by Szabo with the intent of merging contract law into programming protocols on the Internet. Recently, Szabo contrasted the use of smart contracts on Ethereum in relation to the Bitcoin blockchain, “If…
London, United Kingdom, October 28th – Ethereum is happy to announce that Microsoft will sponsor and attend DΞVCON1, the premier Ethereum developer conference. Marley Gray, Director of Technology Strategy US Financial Services at Microsoft said, “Microsoft is excited to sponsor and attend Ethereum’s DevCon1. We find the Ethereum blockchain incredibly powerful and look forward to collaborating within the Ethereum Community. We see a future where the combination of Microsoft Azure and Ethereum can enable new innovative platforms like Blockchain-as-a-Service. This will serve as an inflection point to bring blockchain technology to enterprise clientele”. Ethereum founder Vitalik Buterin notes “DΞVCON1 is…
With DEVCON1 a mere week away, the teams are excited and preparing to share all the great tools and technology the ecosystem has to offer. There will be hundreds of developers and dozens of talks including Nick Szabo, Vitalik Buterin, and Marley Gray from Microsoft. Tickets are limited and we anticipate selling out, so if you haven’t already registered, head on over to https://devcon.ethereum.org to secure your spot now! cpp-ethereum TurboEthereum released 1.0.0 of the C++ tools. Work has been done on state trie pruning and upgrading network protocols (PV 62 & 63). Several Mix bugs have been fixed and…
