Tempo [ /ˈtɛmˌpoʊ/ ]**** is a consensus protocol developed as the fifth iteration of Radix. First proposed in 2017, Tempo pioneered innovations such as ledger pre-sharding to allow for the grouping of related transactions, and ‘lazy’ consensus. The ideas contained in the Tempo whitepaper served as a foundation for Radix's subsequent Cerberus protocol.
