threshold signature

Threshold signatures allow m-of-n parties to jointly sign without revealing their individual key shares.门限签名允许多方（m-of-n）共同签名，而无需泄露各自的密钥份额。

Unlike multisig, threshold signatures produce a single signature on-chain, saving gas and improving privacy.与多签不同，门限签名在链上产生单一签名，从而节省燃料费（gas）并改善隐私。
