Harmony provides a high-throughput, low-latency and low-fee consensus platform designed to power the decentralized economy of the future. It plans to address the issues faced in other blockchain ecosystems through the use of the best research and engineering practices in an optimally tuned system.

The technical focus of the project is on resharding and secure staking with decentralized randomness. Harmony also implements optimal cross-shard routing and fast block propagation.

Effective Proof-of-Stake (EPoS) is a staking mechanism in a sharded blockchain that achieves both security and decentralization. EPoS allows staking from hundreds of validators and the unique effective stake mechanism reduces the tendency of stake centralization.

Unlike proof-of-work (PoW) consensus mechanisms, EPoS is designed for faster processing times and improved scalability. While PoW requires a lot of electrical and computing power, staking consensus methods rely on an abundance of value holders, who become validators. To ensure the protection of nodes and secure the validation process, Harmony introduced the Verifiable Random Function (VRF) for unbiased and unpredictable shard membership. This means that nodes and validators are assigned and re-assigned in a randomized manner.
