Breaking: Bugs Found In Ethereum Clients’ Mainnet Merge Releases

The long-awaited Ethereum Merge has finally started as Ethereum clients release updates in preparations for the Merge on September 15. However, the Go Ethereum and Nethermind have found bugs in their Mainnet updates Geth v1.10.22 (Promavess) and v1.14.0, respectively. Still, the bugs are unlikely to delay the Merge as developers perform quick fixes and the availability of other execution clients.

Ethereum Clients Report Bugs in the Mainnet Merge Updates

The Ethereum clients Go Ethereum and Nethermind have found bugs in their Mainnet Merge updates. Ethereum developer Péter Szilágyi in a tweet on August 23 announced a regression bug in the Geth v1.10.22 (Promavess). It is one of the pull requests (PR) the team merged towards the new storage model or online pruner.

“Aaand our latest release is borked. Geth 1.10.22 contains a regression that causes the trie/state to go bad. Most probably it’s one of the PRs we’ve merged towards the new storage model / online pruner. Trying to find and fix the issue.”

The Go Ethereum team is currently looking to find and fix the issue.

Nethermind core developer “DanielC” replied to Péter Szilágyi’s tweet saying a similar regression bug was found in the release v1.14.0. However, the team has fixed the issue by deciding to switch to a strict stabilization phase before the Merge.

“Recently we’ve had similar regressions in Nethermindeth so we’ve decided to switch to a strict stabilization phase before The Merge. We merge only fixes to the master branch currently.”

The bugs are unlikely to impact the Ethereum Mainnet merge with the Beacon Chain on the anticipated date of September 15. The users can also switch to minority execution clients. Moreover, there are other execution clients to help prepare for the Mainnet Merge.

Until now, several Ethereum clients have released the required Mainnet updates. These include Besu v22.7.1, Geth v1.10.22, Nethermind v1.14.0, Erigon v2022.08.02-alpha, Lighthouse v3.0.0, Teku v22.8.1, and Prysm 3.0.0.

Developers Pushes for Merge on September 15

Ethereum developers are pushing the Merge to trigger by TTD of 58750000000000000000000 on September 15. The plans for the Bellatrix and the Paris upgrades are also in progress.

The Ethereum clients have started rolling out the Mainnet Merge releases that configure the Bellatrix, the Paris, and Merge upgrades.

Also, the Ethereum hash rate is in line with the required average hash rate of 872.2 TH/s for the Merge to happen on September 15.
