Discussion thread for decoupling stake deposits from validator registration

What happens to the fee market when Glamsterdam changes transaction gas costs and the gas limit rises from 60M to 200M? More capacity should ease pressure on fees, but cheaper gas also attracts deman…

Changes in the September 9 and 10, 2026 updates to the Ethlabs Hegotá view

Every year since January 2019, teams from the Ethereum Foundation have spent an afternoon or two on r/ethereum answering questions from the community. The format hasn’t really changed: one thread, te…

Add frame abstraction for transaction validation, execution, and gas payment

This release includes two highlights: improved Solidity Test compilation speed through a porting of our inline configuration parsing to Rust, and bumps of our default templates to Solidity 0.8.34.

I guess the problem needs no introduction. Blind signing has been a big pain, arguably the biggest UX pain, of Ethereum since its inception. It's just not possible for humans to know what they are ab…
