@NIC619 This PR is making a minor change to the deposit contract. ChainStart -> Eth2Genesis

[hwwhww]

I saw @djrtwo changed BLS pubkey/signature -> BLS 12-381 pubkey/signature, and also found @JustinDrake changed proof of possession (a BLS signature) to proof of possession (a BLS12 signature).

I'm inclined to second #419, BLS pubkey/signature sounds more neutral and future-proof to me as these pubkeys and signatures (with BLS12-381 curve) should be fit in the BLS signature scheme, or anything I missed?

cc: @vbuterin regarding "operations -> transactions". I know many months ago you wanted to reserve the term "transaction" for user level. What are your thoughts on this now?

Substrates calls the beacon operations/transactions "extrinsics". See https://www.youtube.com/watch?v=GDvV-Vn2u3w&t=928

Edit: False alert. They do call them "transactions" 😂 https://youtu.be/GDvV-Vn2u3w?t=1022

FYI: we are not renaming operations to transactions in Prysm. We generally think this should be reserved for user level and operations is the more intuitive name.

We are also not renaming chainstart to eth2genesis. For the same reasons: more intuitive with the previous name.
