Last week, Ethereum completed its Gray Glacier hard fork, successfully delaying the difficulty bomb by approximately 100 days. As the network prepares for The Merge, ConsenSys developer Ben Edgington shares critical updates about ongoing preparations and challenges.
Mainnet Shadow Fork #7 (MSF7)
Executed on June 22nd, MSF7 demonstrated smooth functionality for all Merge-related processes, though two non-critical issues emerged:
Erigon Node Observations
- Temporary synchronization difficulties due to shadow fork mechanics
- Already resolved and unrelated to mainnet deployments
Besu Database Corruption
- Concurrency-related issue affecting multi-threaded database updates
- Being urgently addressed with fix expected within 1-2 weeks
Additional deadlock scenarios between Nethermind and Teku clients were identified, prompting protocol adjustments to improve retry mechanisms. These discoveries validate the importance of shadow forks for stress-testing edge cases before full deployment.
Next Steps:
- Mainnet Shadow Fork #8 scheduled for July 5th
Sepolia Testnet Merge Timeline
The Sepolia testnet merger is projected for July 5th, though exact timing depends on:
- Network hash rate fluctuations
- Miner participation patterns

Ropsten Synchronization Testing
EF DevOps teams are conducting intensive blockchain sync tests between client pairs on Merged Ropsten to identify potential synchronization challenges – one of the most complex technical hurdles remaining before full implementation.
Staking Infrastructure Updates
Key developments in Ethereum's staking ecosystem:
✅ Stakehouse Community Call #17

FAQ: Ethereum Merge Essentials
Q: Why delay the difficulty bomb before The Merge?
A: This prevents exponentially increasing block times that could disrupt network usability during transition.
Q: How many testnet merges remain?
A: Sepolia (July) completes major testnets, with potential for additional shadow forks.
Q: What hardware requirements will change post-Merge?
A: GPU mining ends, replaced by modest hardware needs for PoS validation.
