Bech32
Also covering BIP173 and Native segwit address
Bech32 is an address format used to pay native segwit outputs.
Using only 32 letters and numbers, the bech32 address format is case insensitive and includes an error-correction code that can catch almost all address typos (and even identify where the typos occur in some cases). Addresses encode a segwit version, making them forward compatible with a large range of conceivable upgrades.
