Revision as of 17:01, 22 November 2021

Bech32 is a bitcoin address format specified by BIP 0173. It is used for the native segwit version 0 output types, P2WPKH and P2WSH. The upcoming Taproot softfork will add another output type called Pay to Taproot (P2TR). P2TR outputs and future native segwit versions will be using an updated variant of Bech32, called Bech32m (specified by BIP 0350). This page tracks the adoption of Bech32 and Bech32m.

Ideally wallets and services would first support sending to new addresses. When most wallets and services support sending to the new address type, people are more likely to adopt it for receiving.

The amount of bech32 addresses on the blockchain is tracked on this website: https://p2sh.info/dashboard/db/bech32-statistics?orgId=1

Blockchain Explorers

To investigate bech32 capability, you can use mainnet TXIDs 4ef47f6eb681d5d9fa2f7e16336cd629303c635e8da51e425b76088be9c8744c and 514a33f1d46179b89e1fea7bbb07b682ab14083a276979f91038369d1a8d689b or look up the addresses bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq and bc1qc7slrfxkknqcq2jevvvkdgvrt8080852dfjewde450xdlk4ugp7szw5tk9.

Some blockchain explorers can only parse the bech32 address and display it, they don't build an index so users cannot search for bech32 addresses.

To verify bech32m readiness, you can look up the mainnet TXID b10c007c60e14f9d087e0291d4d0c7869697c6681d979c6639dbd960792b4d41 on which the first output should be addressed as bc1pqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqsyjer9e. Note that the superseded bech32 encoding only differs in the last six characters that encode the checksum: bc1pqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqs_3wf0qm_.
