- Dev Update: Formal Methods
Today, I am delighted to announce that Yoichi Hirai (pirapira on github) is joining the Ethereum project as a formal verification engineer. He holds a PhD from the University of Tokyo on the topic of formalizing communicating parallel processes and created formal verification…
- On Inflation, Transaction Fees and Cryptocurrency Monetary Policy
The primary expense that must be paid by a blockchain is that of security. The blockchain must pay miners or validators to economically participate in its consensus protocol, whether proof of work or proof of stake, and this inevitably incurs some cost. There are two ways to pay…
- Onward from the Hard Fork
The foundation has committed to support the community consensus on the admittedly difficult hard fork decision. Seeing the results of various metrics, including carbonvote, dapp and ecosystem infrastructure adoption, this means that we will focus our resources and attention on…
- Hive: How we strived for a clean fork
The DAO soft-fork attempt was difficult. Not only did it turn out that we underestimated the side effects on the consensus protocol (i.e. DoS vulnerability), but we also managed to introduce a data race into the rushed implementation that was a ticking time bomb. It was not…
- Hard Fork Completed
We would like to congratulate the Ethereum community on a successfully completed hard fork. Block 1920000 contained the execution of an irregular state change which transferred ~12 million ETH from the "Dark DAO" and "Whitehat DAO" contracts into the WithdrawDAO recovery…
- To fork or not to fork
The DAO, though not a product developed by the Ethereum Foundation, has been a hot topic as of late, both internally in the organisation as well as within our community. The Hard Fork is a delicate topic and the way we see it, no decision is the right one. As this...
- How to build server less applications for Mist
Ethereum is not meant to be a platform to build esoteric smart contract applications that require a STEM degree to understand, but it aims to be one pillar of a different architecture for applications on the world wide web. With this post we will try to elucidate how this can...
- Taylor’s Summer Update
Hey everyone, I spent some time with our Canadian friends in Toronto after presenting "Ethereum: The World Computer" at Blockchain Training Conference last month and I wanted to provide a quick update on some of the exciting happenings in the Ethereum dev ecosystem. Lots of…
- C++ DEV Update - July edition
Since the last C++ DEV Update, a lot of things happened in the engine room which were not really visible to the outside. This post wants to give an overview about what we are currently working on. Apart from the features side, Bob has been working on a proposed...
- The Devcon2 site is now live!
The Devcon2 web site is officially live now! You can find it at https://ethereumfoundation.org/devcon/ Thanks for everyone's interest, proposals, support and enthusiasm. We have an amazing community and are excited to present the first Ethereum Foundation event in Asia. This…
- Security Alert - DoS Vulnerability in the Soft Fork
Affected configurations: geth 1.4.8 Likelihood: High Severity: High Details: An attack vector has been identified in the freshly released implementation of the DAO soft fork. The fork enactment code in geth (and other clients) allows execution of EVM code up to the block gas…
- DAO Wars: Your voice on the soft-fork dilemma
The last week was quite hectic for all of us in the Ethereum ecosystem. The DAO has shown us that it takes much more effort to write smart contracts than we originally anticipated; but also that it takes a surprising amount of debate to reach a consensus on issues of this scale.…
- Security Alert – Smart Contract Wallets created in frontier are vulnerable to phishing attacks
Affected configurations: All smart contract wallets created using Ethereum Wallet Frontier, version 0.4.0 (Beta 7) or earlier. Wallets created with Ethereum Wallet 0.5.0 and all later versions released after March 3, 2016, are not affected. Likelihood: Low Severity: High...
- Thinking About Smart Contract Security
Over the last day with the community's help we have crowdsourced a list of all of the major bugs with smart contracts on Ethereum so far, including both the DAO as well as various smaller 100-10000 ETH thefts and losses in games and token contracts. This list (original source…
- CRITICAL UPDATE Re: DAO Vulnerability
An attack has been found and exploited in the DAO, and the attacker is currently in the process of draining the ether contained in the DAO into a child DAO. The attack is a recursive calling vulnerability, <span style="font-weight...
- The Ethereum Foundation welcomes Microsoft as the Premiere Sponsor of Devcon2, Shanghai 19-21 September, 2016
London, United Kingdom, June 14, 2016 – The Ethereum Foundation is pleased to announce Microsoft as the Premiere Sponsor of Devcon2, the Ethereum developer conference in Shanghai, 19-21 September, 2016. Devcon2, which will showcase the most up-to-date research and development…
- Smart Contract Security
Solidity was started in October 2014 when neither the Ethereum network nor the virtual machine had any real-world testing, the gas costs at that time were even drastically different from what they are now. Furthermore, some of the early design decisions were taken over from…
- Security Alert - cpp-ethereum’s account unlocking problem not yet fixed [Now fixed]
Affected configurations: cpp-ethereum (eth, AlethZero, …) version 1.2.0 up to 1.2.6 Note: Neither “geth” nor “Mist” nor the “Ethereum Wallet” (unless explicitly used together with cpp-ethereum) are affected by this, they lock accounts correctly again. This is just a quick head's…
- Go Ethereum’s JIT-EVM
The Ethereum Virtual machine is kind of different than most other Virtual Machines out there. In my previous post I already explained how it’s used and described some of its characteristics. The Ethereum Virtual Machine (EVM) is a simple but powe...
- Security Alert - cpp-ethereum keeps accounts unlocked
Affected configurations: cpp-ethereum (eth, AlethZero, ...) version 1.2.0 up to 1.2.5 (fixed in 1.2.6) Note: Neither "geth" nor "Mist" nor the "Ethereum Wallet" (unless explicitly used together with cpp-ethereum) are affected by this, they lock accounts correctly again.Severity:…
