BIP 350 added Bech32m checksums for newer witness versions
BIP 350 specifies Bech32m, an updated checksum variant for witness address versions beyond version 0.
The change prevents certain mutation weaknesses while preserving a familiar human-readable address structure.
Address encodings evolve alongside script versions; BIP 350 helped make Taproot destinations interoperable.
Wallets must recognize the correct checksum scheme for each witness version rather than treating all Bech32-like addresses alike.
