That version was missing Native Introspection & OP_REVERSEBYTES. (P2SH, P2PK (as seen in genesis block), P2PKH, etc) HASH160 is mostly used due to convention and convenience - it has historically been used in p2pkh, p2sh, and p2wpkh addresses, and is usually well supported and understood by any tooling around the bitcoin ecosystem. In english, most bitcoin scripts translate as follows: “In order to spend this bitcoin, one must produce a signature belonging to this public key”, followed by a public key. Thanks for contributing an Taproot N-of-N multisig ([<PubKeys[0:n-1]> CHECKSIGVERIFY] <PubKeys[n-1]> CHECKSIG). This is managed through the scriptPubKey of a P2PKH transaction, which is designed such that it requires the recipient to have the private key associated with the the P2PKH Bitcoin address. P2WSH is a special type of locking script and is not executed like normal Script. Since this is in the input of a coinbase transaction, so far as I know it has no functional purpose for other nodes in the rest of the Bitcoin network. Whether you're decoding Bitcoin addresses, retrieving IPFS hashes, or working with any other Base58 encoded data As of Bitcoin Core 0. 1 parser that can decode any valid ASN.
