3. Put the deposit data together: pubkey is the signing pubkey, withdrawal credentials is the sha256 hash of the withdrawal pubkey (32 bytes), but the first byte of the hash is replaced with the prefix (currently 0 for version 0), breaking the hash, while signature is technically bls_sign(signing_privkey, signing_root(deposit_data)) but due to the circular dependency the signature here is actually ignored (!!) which is not detailed in the spec, and can be nothing, null, or random data.

4. Signature for Deposit call is then again bls_sign(signing_privkey, signing_root(deposit_data)) which should produce 96 bytes.
