More than 5 million ETH has been sent to Ethereum 2.0's deposit contract
The Ethereum blockchain is undergoing a shift from a proof-of-work consensus mechanism to a proof-of-stake one, as part of the main Ethereum 2.0 upgrade. This will move the blockchain away from being reliant on miners to process transactions, instead allowing anyone who is willing to stake 32 ETH to process them instead — at the risk of losing their coins if they act maliciously.
