One of the big challenges is to construct a decentralized protocol that is secure and usable. For this challenge, Threshold ECDSA signatures have received much attention in recent years due to the widespread use of ECDSA in cryptocurrencies. Threshold ECDSA signature enhances the decentralization property and can be used to protect digital assets. Although many threshold signature protocols have been proposed, they are unsuitable for deployment scenarios. This is because their protocols are largely lacking in robustness and are structurally unable to integrate into existing blockchains. We propose a threshold ECDSA signature scheme with basic robustness in the signature phase based on the ElGamal commitments.
