For The Better

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 t…

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 …

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 …

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 Founda…

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 E…

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 consens…

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. Likelihoo…

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. T…

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,

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…

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 decision…

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. …

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…

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 account…

Affected configurations: All Go client versions  Likelihood: Very low Severity: High Details: A bug in Geth (and potentially other clients) may suffer from a DoS attack and allows remote attackers to stall synchronisation process almost indefinitely…
