-Let `serialized_deposit_data` be the serialized form of `deposit_data. It should be the `DepositParametersRecord` followed by 8 bytes for `deposit_data.value` and 8 bytes for `deposit_data.timestamp`. That is, it should match `deposit_data` in the [Ethereum 1.0 deposit contract](#ethereum-10-chain-deposit-contract) of which the hash was placed into the Merkle tree.
