Harmony is an interoperable sharding protocol offering a two-way Ethereum bridge. Powered by the Harmony One token (ONE), the Harmony blockchain is an independent blockchain designed to enable ultra-fast transactions and interoperability as an advanced layer-2 solution for Ethereum. Harmony makes it easy for developers to build and scale creative, intuitive decentralized applications (dApps) that enable frictionless, cross-chain token swaps.
Key Features of Harmony Protocol
- Interoperability: Seamlessly connects with Ethereum via a two-way bridge.
- Scalability: Achieves 2,000+ transactions per second (TPS) through sharding.
- Low Fees: Near-zero transaction costs compared to Ethereum mainnet.
- Developer-Friendly: Uses Solidity and Ether.js for dApp development.

How Harmony Works
Decentralization & Sharding
Harmony’s network consists of four shards, each supporting 250 validators. The beacon chain (Shard 0) coordinates transactions across shards, enabling parallel processing.
Unique Consensus:
- EPoS (Effective Proof-of-Stake): Combines FBFT (Fast Byzantine Fault Tolerance) for instant finality.
- Anti-Centralization: Incentivizes stake distribution to prevent validator dominance.
ONE Token Utility
- Staking: Secure the network and earn 9–150% APY.
- Governance: Future voting rights for protocol upgrades.
- Transaction Fees: Burned to offset inflation.
Why Choose Harmony?
- Ethereum Compatibility: Easy migration for developers.
- Cross-Chain Swaps: Swap assets between Harmony and Ethereum in seconds.
- Grants Program: $7M allocated for ecosystem projects.

FAQs
Q: What is Harmony’s transaction speed?
A: 2,000 TPS, with plans to scale to 1M TPS via additional shards.
Q: How do I stake ONE tokens?
A: Delegators need 1,000 ONE; validators require 10,000 ONE.
Q: Is Harmony fully decentralized?
A: Over 1,000 nodes exist, with 64% operated by the Pangaea community.
Conclusion
Harmony merges Ethereum’s developer ecosystem with high-speed, low-cost transactions. Its ONE token powers staking, governance, and cross-chain interoperability, positioning it as a top layer-2 solution.
For developers: Harmony’s tools and grants offer a prime opportunity to build scalable dApps.
