...orithm to implement signature aggregation.In the case of multi signature with ECDSA, if there are N private keys signed, the N signatures need to be verified respectively. Because of the linear characteristic of Schnorr Signature Algorithm, in the same case, the signatures of N private keys can be "aggregated" into one signature. The principle is as follows:Because the points on the elliptic curve...
