About Harmony

Harmony (ONE) is an EVM-compatible layer-1 blockchain that implements state, network, and transaction sharding, coordinated by a beacon shard (Shard 0) for cross-shard synchronization. The design targets fast finality and horizontal scalability via multiple uniform shards. 

Consensus is Effective Proof-of-Stake (EPoS), which bounds a validator’s effective stake around the median stake to discourage concentration while still supporting delegation and compounding. Rewards are proportional to effective stake and validator performance. 

Harmony launched mainnet in June 2019 and open staking in May 2020. The network remains operational post-2022, while cross-chain connectivity shifted from Horizon toward LayerZero-based bridging for selected assets. 

The ecosystem uses HRC-20/HRC-721 token standards for fungible and NFT assets.
