The next major Ethereum upgrade, Shanghai, now has a testnet

The Shanghai upgrade will be Ethereum’s first upgrade since the Merge in September, when Ethereum transitioned from a proof-of-work consensus mechanism to a proof-of-stake model.

The most anticipated proposal is EIP 4895, which will allow for those who have staked ether (ETH) on the Beacon Chain to withdraw their stake, along with any rewards they have earned over time. Ethereum has enabled the ETH 2.0 staking contract since November 2020. As of now, the amount locked in ETH 2.0 is more than 14.2 million ETH, worth $19 billion.
