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 the Sepolia upgrade scheduled on February 28 at 4 AM UTC. The client releases for the upgrade and blog on the same will be announced early next week.
Ethereum’s Shanghai upgrade will happen in March which will enable withdrawals of Ethereum staked as well as rewards on the Beacon chain. It is triggered by three testnets Zhejiang, Sepolia, and Goerli.
Shapella refers to two Ethereum upgrades, “Shanghai” and “Capella”, allowing withdrawals on the execution layer and enhancing the Beacon Chain consensus layer. Other changes also reduce gas fees on the network.
Other topics such as 4844 transaction changes, SSZ, RPC, and SELFDESTRUCT improvements were also discussed at Ethereum’s All Core Developers Conference Executive meeting on Thursday.

How the Upgrade Will Impact Ethereum Price
Ethereum Shanghai upgrade is one of the most awaited changes after September’s Ethereum Merge. ETH stakes are waiting to remove their Ethereum staked on the beacon chain.
Moreover, Ethereum staking is rising ahead of the Shanghai upgrade. Ethereum staked on the beacon chain has jumped 16,692,823 and 519,517 active validators. ETH price will fluctuate massively near the upgrade, with experts pointing to a retest of $2,000.
Ethereum price is currently trading at $1,662, down 1% in the last 24 hours and up 8% in a week.
