然后可以确认输出的 verification_key.json 和proof.json 文件中有一个"curve": "bls12381"项,而不是"curve": "bn128"项。 从proof.json 文件中获取A、B、C参数,从 verification_key.json 文件中获取 α、β、ϒ、δ参数,使用 public.json 文件中的ic item和公共输入计算 L 参数: 其中公共输入 w = (...

在安装了eip2333-tool之后,可以使用以下命令生成BLS12-381椭圆曲线密钥对:eip2333-tool new —curve bls12-381这将生成一对公钥和私钥,分别以PEM格式输出到终端。请注意,生成的私钥应该妥善保管,不要泄露给他人。步骤三:使用生成的密钥对进行签名和验证一旦生成了BLS12-381密钥对,就可以使用私钥对消息进行签名,并使...

Even though I was able to derive an Ethereum public key, I didn't expect to be able to sign valid Ethereum transactions, because I thought that the different curve parameters would prevent me from generating valid signatures for the transactions. ...
