Ethereum Foundation Activates Protocol Upgrade Bringing Proposer-Builder Separation
The latest in this situation
How it started
What happened
The Ethereum Foundation announced that the Glamsterdam upgrade, which includes EIP-7732, will activate on the Hoodi testnet on October 26, 2026. This upgrade integrates proposer-builder separation directly into Ethereum’s consensus rules, formalizing a mechanism that previously relied on out-of-protocol agreements. Separately, former contributors like BitMine Immersion and Sharplink backed Ethlabs to prepare Ethereum for institutional use.
Why it matters
The protocol changes formalize the handoff between block proposers and block builders within the network itself, which is a major structural shift for Ethereum. The push for institutional adoption suggests increasing demand for Ethereum as a neutral settlement layer for global finance.
Who's involved

- EthereumPublic blockchain platform undergoing protocol upgrades and institutional adoption efforts.
- BitMine ImmersionCryptocurrency firm that has pivoted its business model to rely on Ethereum as its primary treasury reserve asset.
Who could feel it
Possible knock-on effectsThese are possibilities Brind reasoned out, not predictions, and not advice. Most are not stated in any report.
- BitMine ImmersionSpeculative
BitMine Immersion might see the long-term value of its ETH treasury undermined if core protocol funding issues persist.
- Ethereum FoundationSpeculative
The Ethereum Foundation could face challenges in maintaining core protocol funding if warnings about a development funding crisis are accurate.
