Banca d'Italia published a paper on the FROSTed Byzantine Fault Tolerance (FBFT) protocol, an approach to DLT proof of authority (PoA) validation meant to strengthen the security of the ledger, its tolerance to faults or attacks, and the confidentiality of validators. It combines the practical byzantine fault tolerance (PBFT) algorithm with the flexible round-optimized Schnorr threshold (FROST) signature scheme. The resulting system is an alternative platform for a distributed, resilient transactional system. Operated by a set of trusted actors, distributed at geographic scale, it holds potential for mission-critical applications, such as wholesale and retail CBDC, and asset tokenization schemes.
