The Goerli network has enabled Ethereum's Shapella update, which allows for the unstaking of ETH.
The hard fork was not smoothly implemented because testnet validators lacked motivation to upgrade their client software.
The mainnet upgrade, which includes various changes, is anticipated to begin next month.
The hard fork had problems even though it had been activated successfully on the Goerli testnet because some testnet validators had not updated their client software in advance of the fork. The testnet's ETH is "worthless," according to Tim Beiko, an Ethereum core developer, thus testnet validators have "less incentive" to upgrade. Nevertheless, he anticipates that validators will make the necessary changes prior to the fork on the Ethereum mainnet.
After some delays in preparing the Sepolia and Goerli testnets for the split, Shapella's activation on the Ethereum mainnet is planned for early April. By allowing both partial and full withdrawals, the hard fork will release 17.6 million ETH, or more over $30 billion at the present rate.
On the other side, the Ethereum Foundation has previously said that numerous measures have been taken to prevent a rush of ETH supply from hitting the market after the update has been put into place.
For instance, while only about 2,200 withdrawals are permitted each day, the total number of withdrawals permitted over a 24-hour period will only represent about 0.40% of the total amount of ETH staked. This is because processing an epoch takes roughly five or six minutes, and an epoch can only have a maximum of ten validators assigned to it.
