Effective Proof of Stake (EPoS)

Harmony’s proprietary Proof-of-Stake (PoS) mechanism, Effective Proof of Stake (EPoS), is intended to increase network security and decentralization. EPoS enables thousands of validators to stake in an equitable and fair manner, reducing the possibility of staking centralization. Harmony’s EPoS staking framework supports reward delegation and reward compounding, and it promotes 100% network uptime by penalizing elected but unavailable nodes and penalizing validators who double-sign transactions.
