This post gives a high-level overview of a 9‑round threshold ECDSA signing protocol implemented in Binance's tss-lib (based on GG18), explaining how MtA (multiplicative-to-additive) share conversion, Paillier homomorphic encryption, distributed nonce and key shares, and various Schnorr and range proofs enable n-party signing without reconstructing the private key; deeper technical details on MtA and ZK proofs are promised in follow-up posts.
