Ethereum All Core Devs Consensus call No. 189

Ethereum developers will hold All Core Devs Consensus call No. 189 online on October 15, 2026, from 14:00 to 15:30. The agenda covers the Glamsterdam and Hegotá hard forks and involves ETH.

What is happening

The 90-minute call brings together Ethereum core developers to discuss the Glamsterdam and Hegotá upgrades, as well as the process by which hard forks are developed. It is a development discussion, not an upgrade activation, so no protocol changes go live as a result of the meeting.

Glamsterdam includes protocol-level proposer-builder separation and block access lists, which are intended to improve transaction processing and network efficiency. Developers activated it on the Sepolia testnet on October 6 with a 200 million gas limit for testing.

Hegotá is expected to follow in 2027. Its proposed changes address censorship resistance, transaction processing and security, and Fork-Choice Enforced Inclusion Lists are among its confirmed priorities.

Why it matters

Consensus calls are where Ethereum's core developers coordinate the scope and sequencing of network upgrades. Discussion of testnet results and fork planning gives an indication of how work on Glamsterdam is progressing and how Hegotá is being shaped, which is relevant to anyone following Ethereum's roadmap.

For ETH holders and traders, the call is a source of information on upgrade priorities rather than a market-moving event in itself. Nothing is activated on mainnet, and any decisions or timelines mentioned in the discussion remain subject to further testing and developer consensus. Watch for updates on Glamsterdam testing, any changes to the Hegotá feature list, and comments on how the fork development process may be adjusted.
