Bitcoin Improvement Proposal Modifications and Deletions for BSHA3

For anything unmentioned, BSHA3 corresponds to Bitcoin.

Here is a listing of chain nuances:

• BIP34 is always enabled. However, for blocks under 16, push_int64 is instead used of the encoding in the original BIP. The genesis block is also mined with a CScriptNum(0) for conformance. See: bitcoin/bitcoin#14633 for Bitcoin's discussion.

• Although it calculates the hashes of the leaves using SHA3d, BSHA3 performs the reduction step of merkle root calculation using SHA256d. Satoshi's classic Merkle Tree implementation (standard, leaf-node weakness) is used.

• CSV (BIP 68, 112, 113) is always enabled. This means its code has been migrated out of the BIP9-activation path.

• Segwit is always enabled. This means its code has been migrated out of the BIP9-activation path.

• The Segwit commitment header has been changed to 0f0f0f0f, from Bitcoin's aa21a9ed. This is for simplicity only. See: https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki#commitment-structure for Bitcoin's specification.

• Addresses are in a modified base58check format - the checksum is calculated by 2 rounds of SHA3-256 instead of SHA256.
