Ethereum core developer Tim Beiko on Friday said developer Marius VanDerWijden found a vulnerability with the public test network Shapella. The issue appeared during the full synchronization of empty blocks, which has no transactions or withdrawals.
Other clients also reported the same issue. VanDerWijden said the team found that Go Ethereum (Geth) client nodes facing difficulty syncing with the Zhejiang testnet.
“The last 4 and a half stressful hours of debugging culminated in this amazing bug fix. We got reports that geth nodes wouldn’t sync the Zhejiang devnet correctly. The issue was that if a block body was empty (no tx, no withdrawals) we wouldn’t initialize it correctly.”
However, developers believe the problem can be fixed with a patch as it’s fairly easy to test. In addition, core developer Tim Beiko asserts an additional Hive test is proposed for ensuring the issue is resolved correctly.
Interestingly, Ethereum core developers think the issue likely will not impact
