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 limit without paying for gas. This can slow down mining and prevent inclusion of

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 year, Devcon2 (September 19, 20, 21) will be a featured conference at the International Blockchain Week in Shanghai

Fusaka follows this year’s Pectra upgrade, representing a major step forward in Ethereum’s scaling roadmap that improves L1 performance, increases blob throughput, and enhances user experience. The Fusaka network upgrade is scheduled to activate on the Ethereum mainnet at slot 13,164,544 (December 3, 2025, 21:49:11 UTC). Fusaka also introduces Blob Parameter Only (BPO) forks to

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 process for re-licensing of the C++

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 things are brewing behinds the scenes, so let’s jump in!

How to build server less applications for Mist | Ethereum Foundation Blog Posted by Alex Van de Sande on July 12, 2016 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

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 is not a decision that

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 contract. The fork itself took place smoothly, with roughly 85% of miners mining on

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 ideal, and even though averted at the last

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 the chain which is now called ETH (ie. the fork chain). That said, we recognize
