The Merge: Latest Progress & Insights
Testing Updates
Key developments from the May 9 Merge testing call:
- Geth Critical Fix: Addressed a scenario where consecutive blocks by the same validator could force nodes into invalid chains. Mitigations now prevent repeated snapshot syncs after a full sync.
- Consensus Layer Simulator: Developer Marius is advancing this tool for merge readiness.
- Terminal Block Hash Override: Discussions ongoing about emergency use cases and testing parallel to testnet deployments.
Testnet Timeline (Proposed):
- May 13: Select Ropsten’s Terminal Total Difficulty (TTD).
- May 16–18: Client releases.
- May 18/19: Ropsten fork announcement.
- June 1: Ropsten Bellatrix upgrade.
- Early June: Ropsten Merge execution.

Optimistic Rollup Fee Variations Explained
Researcher @bkiepuszewski breaks down fee disparities:
