Ethereum enabled staking for anyone with a minimum of 32 ETH. Where can I see the code of their staking protocol? Is it a .sol file? Is it a contract address whose code is viewable on Etherscan? Please include link, would like to understand how staking is programmed.
The address can be obtained from different sites.
You can read the code from here.
There's a github repo https://github.com/ethereum/consensus-specs/tree/dev/solidity_deposit_contract.
