The Frontier

Coldcard 6.5.0 adds support for signing Musig2 UTXOs, BIP322 signed messages for Miniscript and Musig2 proof of reserves, Miniscript/Minitapscript, Taproot multisig up to eight leaves, and BIP-129 for secure multisig setup.

LND #9985 promotes simple Taproot channels to production status. It incorporates `OP_CHECKSIGVERIFY` for Tapscripts and improved map-based nonce handling linked to funding transaction IDs, serving as groundwork for future splicing.

Danny Knowles explains that a cryptographically relevant quantum computer could steal coins from exposed public keys, affecting addresses with a viewable public key on-chain, such as Satoshi's coins and Taproot addresses.
