Blockstream and Bitcoin Core developer Pieter Wuille proposed the concept of Tree Signatures, a multisig method with enhanced privacy features. Tree signatures can implement transactions that require more than one key-holder more efficiently than Bitcoin scripting.

Wuille explained:

“Merkle tree keys support very large 1-of-N. Schnorr signatures support very large M-of-M. This means that if we can write our spending conditions as a 1-of-(N possible M-of-M’s), we can build a Merkle tree consisting of Schnorr combined public keys.”

VP of Communications at ChangeTip Victoria van Eyk said:
