Harmony ONE

Applications and network fees.

Harmony is a public blockchain for smart-contract applications and digital transfers. ONE is its native coin.

What is Harmony?

Harmony runs smart-contract applications and uses proof of stake to coordinate network participation. ONE pays transaction fees and can be delegated to validators under the network’s staking rules.

Staking does not guarantee profit. Validator behavior, withdrawal rules, application failures, bridges, and changes in ONE’s value can cause losses.
