summary

Taproot activates at block 709632 (around November 14) as a soft fork, so upgraded nodes start enforcing new Taproot validation while old-valid transactions remain valid; non-upgraded nodes treat Taproot spends as non-standard. Wallet support is limited at launch: Bitcoin Core can create Taproot wallets via RPC by importing a descriptor but not yet via the UI. Taproot brings Schnorr signatures, Tapscript validation rules, a new address format (bech32m), ~43 vbyte outputs and ~10 vbyte smaller inputs, big multisig savings with MuSig, and PSBT extensions for Taproot.
