Summary
In September, the Ethereum network moved from a proof of work to a proof of stake model. However, for those with ETH staked on the network, there was no option to unstake ETH until a future set of upgrades.
There are two associated upgrades titled “Shanghai” (execution layer) and “Capella” (consensus layer) that will go live in a hard fork of the Ethereum mainnet (PROD environment) in slot 6,209,536, which will arrive on Apr. 12, 2023, around 10:27:35 PM UTC. Ethereum testnet Goerli (CERT environment) went through this hard fork last month without issue.
There is no expected downtime during the fork and the network should automatically follow the new chain. Our teams will be monitoring this upgrade closely.
