Harmony at a glance.
Harmony launched its mainnet in 2019 as a sharded proof-of-stake network designed to run Ethereum applications at lower cost. It splits work across multiple shards and uses a delegation-based staking model to secure each one. Here is how it works and what it is used for, not the price.

How Harmony works.
Harmony secures its network with Effective Proof of Stake, a staking design built for a sharded chain. Token holders stake ONE or delegate it to validators, who are spread across shards so that each shard carries a comparable amount of stake. EPoS adjusts rewards so that very large validators are pushed to run additional nodes rather than concentrate stake, and double-sign behavior can be slashed.

Sharding
Harmony divides state, network, and transaction processing across multiple shards so they can produce blocks in parallel rather than one global chain handling everything.
EVM compatibility
The network runs Ethereum-style smart contracts, so contracts and tooling written for the EVM can be deployed on Harmony with familiar workflows.
ONE token
ONE is the native token. It pays transaction fees and is staked or delegated to validators to help secure the shards and earn staking rewards.
Epochs
Time on Harmony is grouped into epochs of a fixed number of blocks. Validator sets and shard assignments are updated at epoch boundaries.
What Harmony is used for.
Harmony hosts EVM-based decentralized applications, token contracts, and cross-chain tools built on its sharded design.
Smart contract apps
Developers deploy EVM contracts for decentralized finance, tokens, and other on-chain applications on Harmony.
Staking and delegation
Holders stake ONE directly or delegate to validators to take part in securing shards and earning rewards.
Low-cost transfers
ONE is used to send value and interact with contracts at low fees compared with mainnet Ethereum.
