Roundup #6

Metropolis is finally (almost) here! The fork for Byzantium, the first and larger part of Metropolis, succeeded on the testnet over two weeks ago, and the likely date for the fork on the mainnet has been set to block 4.37 million, which is expected to be on Oct 17. New features include opcodes such as REVERT and RETURNDATACOPY, as well as precompiles that can be used to support a wide array of cryptographic algorithms. At the same time, we have been...

Roundup #5

Development has steadily continued over the last month and a half as we approach the launch of Metropolis. Over a series of core dev calls over the last few months, we have specified and finalized the EIPs for Metropolis, and made the appropriate changes to the Yellow Paper. Metropolis has now been split up into two consecutive forks, named “Byzantium” and “Constantinople”. EIPs for Byzantium (Metropolis part one) are essentially finalized, and the last remaining work to be done has...

Statement Objecting To EME as a W3C Recommendation

The Foundation believes Encrypted Media Extensions (EME) should not be published as a W3C Recommendation, and we are now making public the formal objection the Ethereum Foundation submitted to the W3C opposing the recommendation of EME. As a member of the W3C, the Ethereum Foundation contributes to the standards-making process and votes on matters such as the EME recommendation. Many developers and researchers at the Ethereum Foundation conduct security research and build software that use web technology, and from that perspective, we...

Roundup Q2

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 growth in usage, to the point that it now processes as many transactions per second as Bitcoin. To accommodate the increased load, which has on a few occasions reached the network’s full capacity for hours at a time, the community independently came together and miners voted to increase the gas...

Roundup Round III

Over the last month and a half we saw vigorous ongoing research and development on all sides of the Ethereum roadmap, and progress is rapidly starting to translate into real results that can be run and verified inside of an Ethereum client. On Metropolis: Agendas for core dev meetings 15 and 16 here: https://github.com/ethereum/pm/issues/13 and https://github.com/ethereum/pm/issues/14 List of accepted EIPs here: https://github.com/ethereum/EIPs/blob/master/README.md (mostly agreed on, though we are still going back and forth on details such as gas costs) Most...

Solidity optimizer bug

A bug in the Solidity optimizer was reported through the Ethereum Foundation Bounty program, by Christoph Jentzsch. This bug is patched as of 2017-05-03, with the release of Solidity 0.4.11. Background The bug in question concerned how the optimizer optimizes on constants in the byte code. By “byte code constants”, we mean anything which is PUSHed on the stack (not to be confused with Solidity constants). For example, if the value 0xfffffffffffffffffffffffffffffffffffffffffffffffe is PUSHed, then the optimizer can either do...

Geth 1.6 – Puppeth Master

Cramming in a lot more goodies than originally anticipated, the Go Ethereum team is proud to finally deliver the first incarnation of the 1.6 Geth release series! Glimpsing through the commit list, this is going to be a monster post! Toml configuration files For a very long time now, people were requesting that we support configuration files to aid in switching between different public and pirate chains. We didn’t focus much on private networks, so we’ve always pointed people towards...
