Circle Research releases "ECDSA Signature Robust Thresholds" white paper

Circle's co-founder and CEO Jeremy Allaire announced that Circle Research has released a white paper on "Robust Thresholds ECDSA Signatures" and an open-source Golang implementation of CGG+21 threshold signatures. The goal is to identify signature signers who behave improperly in real-time by combining the CGG+21 signature protocol with the CGG+21 traitor tracking protocol, allowing third-party observers to identify malicious signers in real-time to improve blockchain transaction security. Circle Research also stated that the CGG+21 signature algorithm is a recommended update to GG18. Users of Binance tss-lib GG18 library can switch to Circle Research's CGG+21 signature module while retaining their existing keys. CGG+21 requires fewer communication rounds than GG18 and can significantly shorten signature time in cold storage scenarios.
