Validator Registration Contract

A validator will deposit 32 ETH to the registration contract. The contract will generate a receipt showing the validator as a qualified validator. The deposit is considered to be burned. As you burn the 32 ETH to participate, the beacon chain will see it and will credit the validator with the validator bond, At some point in the future, after a hard fork, the original deposit + interest can be withdrawn back on one of the shards.
To call the registration function, it takes arguments of pubkey, proof_of_possession, withdrawal_credentials and randao_commitment. If the user wants to deposit more than DEPOSIT_SIZE ETH, they would need to make multiple registration calls.
When the contract publishes the ChainStart log, beacon nodes will start off the beacon chain with slot 0 and last recorded block.timestamp as beacon chain genesis time. The registration contract generate receipts with the various arguments for consumption by beacon nodes. It does not validate proof_of_possession and withdrawal_credentials, pushing the validation logic to the beacon chain.
