Optimum ships a memory stack — Optimum P2P, DROM and DAM — built on Random Linear Network Coding (RLNC) that composes equations at intermediate nodes instead of forwarding shards. Testnet benchmarks show Optimum P2P cuts average latency and its standard deviation versus GossipSub, with the largest gains under congestion where gossip latency spikes nonlinearly. The system runs live with validators on board, improves bandwidth utilization and reduces transaction-delays and gas-fee exposure, and the encoded, decentralized propagation proves functional in production tests.
