What is Harmony (ONE) ?

Harmony is a secure and fast decentralized application (DApps) blockchain. Its four shards, 1000-node production mainnet produces blocks and runs Ethereum applications in two seconds.While enabling stake delegation, reward compounding, and double-sign slashing, the Effective Proof-of-Stake (EPoS) decreases centralization. Harmony's goal is to create an open network of nodes that is managed and administered by a broad community. Harmony's network layer is built on the libp2p protocol for network message broadcasting and the stream protocol for state synchronization. It uses RaptorQ fountain code and the Adaptive Information Dispersal Algorithm to broadcast huge blocks rapidly and effectively, resulting in great performance.
