Nero: A Deterministic Leaderless Consensus Algorithm for DAG-Based Cryptocurrencies

This paper presents the research undertaken with goal of designing a consensus algorithm for cryptocurrencies less latency than current state-of-the-art while maintaining level throughput and scalability sufficient real-world payments. The result is Nero, new deterministic leaderless byzantine in partially synchronous model that especially suited Directed Acyclic Graph (DAG)-based cryptocurrencies. In fact, Nero has communication complexity O(n3) terminates two message delays good case (when there synchrony). shown to be correct, we also show it can provide eventual order. Finally, some performance results are given based on proof concept implementation Rust language.
