Schnorr signature

Schnorr signatures are smaller and more efficient than ECDSA signatures, and they enable key aggregation.Schnorr 签名比 ECDSA 签名更小、更高效，并且它们支持密钥聚合。

With Schnorr signatures, multi-party transactions can be made to look identical to single-signature transactions on-chain.通过 Schnorr 签名，多方交易在链上可以看起来与单签名交易完全相同。
