Some of the validators did not upgrade the software before upgrading the Goerli testnet

What’s new? On March 15, Ethereum blockchain developers performed a Shanghai-Capella (Shapella) upgrade on the Goerli testnet. Unlike the February upgrade to the Sepolia network, this time the process went through a number of technical problems. Thus, according to Tim Beiko, one of the core Ethereum developers, there was a problem with the processing of deposits, because some of the validators of the testnet did not upgrade the software in time. He noted that the validators had less incentive to run and monitor the node because ETH in the testnet is worthless.

What other problems were reported? Another difficulty was the large number of withdrawal credential changes handled right during the fork. Given that this was the first time people were able to submit these changes, a much larger number of requests had to be processed, which could have resulted in missed blocks/attestations on nodes with low computing resources.

Eventually, the team was able to resolve the above issues and successfully implement the hard fork.

Shapella includes EIP-4895, which will allow ETH coins to be withdrawn from staking. According to cryptocurrency tracker Dune, more than 8,5 million ETH are locked in dedicated wallets as of March 15.

An Ethereum Improvement Proposal (EIP) is a proposal to improve the network.

As of March 15, 09:00 UTC, ETH is trading at $1697, having gained 2,02% in 24 hours (Binance’s data).

The release of the Shanghai upgrade was first announced in December 2022. At that time, the developers also announced plans to release a set of previously agreed-upon upgrades, including EIP-3651, EIP-3855, and EIP-3860. However, the team later decided to remove any additional EIPs from the upgrade so as not to delay the timeline for unstaking ETH.
