Author: longcpp At present, the mainstream signature mechanism is ECDSA signature mechanism based on secp256r1 or secp256k1 curve. When using ECDSA signature mechanism, a little carelessness will cause various security problems. For details, please refer to “seven sins of ECDSA in blockchain application”. Besides security, the efficiency of signature mechanism is also an important consideration […]
