Just-In: Ethereum Shanghai Upgrade may be delayed as developers discover issues


Tim Beiko, an Ethereum core developer, said Friday that Marius VanDerWijden discovered a vulnerability in Shapella’s public test network. The issue was discovered during full synchronization empty blocks, which does not allow transactions or withdrawals.
Other clients reported the same problem. VanDerWijden stated that the team discovered that Go Ethereum (Geth), client nodes were having difficulty syncing to the Zhejiang testnet.


“The amazing bug fix was achieved after 4 and a 1/2 stressful hours of debugging. There were reports that geth nodes weren’t synchronizing the Zhejiang Devnet correctly. The problem was that if a block was empty (no withdrawals, tx), we wouldn’t initialize the block body correctly.
Developers believe that the problem can be fixed by a patch, as it is easy to test. Core developer Tim Beiko also stated that an additional Hive test was proposed to ensure the issue is properly resolved.
The issue is unlikely to impact the Sepolia upgrade scheduled for February 28th at 4 AM UTC. The blog and client releases for the upgrade will be announced in the early part of next week.
