#### `BLSVerify`
`BLSVerify` is a function for verifying a BLS12-381 signature, defined in the [BLS12-381 spec](https://github.com/ethereum/eth2.0-specs/blob/master/specs/bls_verify.md).
### On startup
A valid block with slot `INITIAL_SLOT_NUMBER` (a "genesis block") has the following values. Other validity rules (e.g. requiring a signature) do not apply.

For each `deposit` in `block.body.deposits`:
* Let `serialized_deposit_data` be the serialized form of `deposit.deposit_data`. It should be the `DepositParameters` 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.
