Note: Last week, Ethereum successfully completed the Gray Glacier (Gray Glacier) hard fork upgrade, which delayed the difficulty bomb by about 100 days. For the next merger of Ethereum, Ben Edgington, a developer from ConsenSys, shared Some information (with deletions in translation).
The seventh shadow fork of the main network
We performed MSF7 (7th mainnet shadow fork) on June 22nd and everything directly related to the merge went well, but 2 issues arose (not directly related to the merge):
1. Erigon has some observation difficulties, which are related to the setting mechanism of the shadow fork. It is not a problem for the real mainnet fork, and the problem has been fixed.
2. The Besu node encountered a database corruption problem, which seems to be related to concurrency (multiple threads update the database at the same time), and this situation has also been found outside of merging. The team is urgently fixing this issue, it's not only related to the merge, it should be done within a week or two.
There is also a stalemate problem between Nethermind and Teku, basically, each side is waiting for the other. Anyway, Teku has been updated to retry more aggressively, which should fix the problem. Prysm will do the same update.
Mining these edge cases is why we shadow fork! Next will be full steam ahead.
According to the plan, the 8th shadow fork of the mainnet will take place on July 5th.
Sepolia Testnet Merger
The Sepolia testnet will be merged around July 5th. You can follow bordel.wtf to check the time. The merge time depends largely on the computing power of the network. Sometimes some people will add a lot of computing power, so the specific The timing of the merger is uncertain.
Ropsten sync test
Synchronizing two blockchains managed by two separate clients presents some challenges, and this is probably the trickiest part of merging that we have to consider. For this reason, the synchronization process between paired clients has received some additional scrutiny. To this end, the EF DevOps team is running a series of tests on the Merged Ropsten testnet and documenting their findings.
Staking
The 17th Stakehouse Community Call was held a few days ago, under the banner of "lowering the technical barriers to staking Ethereum Solo", these have become a very good resource.
I highly recommend that you watch the live broadcast and even join the conference call if you can, you will learn a lot.

Research
Vitalik touched on the topic of possibly limiting validator set size in a recently published survey post, which is an interesting exploration of the various tradeoffs we face.
