Human meaningful witness versioning

In the ongoing discussions about Bitcoin's address encoding, Ethan Heilman highlights a key feature of the bech32 format. The primary characteristic of bech32 that stands out is its handling of the push operation within Bitcoin addresses. Specifically, bech32 addresses do not encode the push directly into the address. Instead, the length of the witness program, which is an essential component for transaction verification and execution in the Bitcoin blockchain, is determined based on the overall length of the address itself. This method contrasts with previous addressing schemes by offering a more streamlined approach to address generation and interpretation, potentially simplifying processes for users and systems interacting with Bitcoin's blockchain.
