What is harmony?
An introduction to harmony one blockchain
Harmony is the next generation open and fast blockchain. Its mainnet runs ethereum applications with 2-second transaction finality and 1000 times lower fees compared to other chains. Harmony is your open platform for assets, collectibles, identity, governance. Its secure bridges offer cross-chain asset transfers with ethereum, binance and 3 other chains.
Harmony’s bridges can connect any Proof-of-Work and Proof-of-Stake chains. Our FlyClient architecture is fully trustless and highly gas-efficient. Currently, our bridges for Ethereum and Binance Smart Chain secure tens of millions cross-chain assets.
Developers simply change Chain ID and enjoy faster EVM executions identical at the bytecode level. They can use their familiar and standard Web3 tooling to easily migrate to Harmony.
What about users? They can continue to use MetaMask or Ledger — but now pay minimal fees. Any Ethereum wallets or portals can work on Harmony without code changes or new installs — we are fully compatible for both transaction messages and execution environments.
