Multi-party ECDSA

This project is a Go implementation of {t,n}-threshold ECDSA (elliptic curve digital signature algorithm).

Threshold ECDSA includes two protocols:

Key Generation for creating secret shares.
Signing for using the secret shares to generate a signature.

ECDSA is used extensively for crypto-currencies such as Bitcoin, Ethereum (secp256k1 curve), NEO (NIST P-256 curve) and much more. This library can be used to create MultiSig and ThresholdSig crypto wallets.
