FROST is a new threshold signature scheme that provides efficient and flexible threshold signatures for blockchain systems. It uses Schnorr signatures and achieves high efficiency and security while also allowing for flexible threshold parameters. The authors demonstrate its performance and security through extensive analysis and experiments on real-world datasets. Unlike signatures in a single-party setting, threshold signatures require cooperation among a threshold number of signers each holding a share of a common private key. Consequently, generating signatures in a threshold setting imposes overhead due to network rounds among signers, proving costly when secret shares are stored on network-limited devices or when coordination occurs over unreliable networks. In this work, we present FROST, a Flexible Round-Optimized Schnorr Threshold signature scheme that reduces network overhead during signing operations while employing a novel technique to protect against forgery attacks applicable to similar schemes in the literature. FROST improves upon the state of the art in Schnorr threshold signature protocols, as it can safely perform signing operations in a single round without limiting concurrency of signing operations, yet allows for true threshold signing, such that only a threshold t out of n possible participants must sign to authenticate a message. Additionally, FROST provides efficient and flexible threshold parameters, allowing users to choose their desired level of security and efficiency based on their specific use case. We demonstrate the performance and security of FROST through extensive analysis and experiments on real-world datasets, showing its superiority over existing threshold signature schemes in terms of both efficiency and security.
