About

Harmony is a Layer 1 blockchain that uses Effective Proof of Stake (EPoS) consensus and state sharding to achieve scalability and decentralization. The platform was designed to support the creation of decentralized applications with two-second transaction finality and low fees. Harmony features random sharding using a verifiable random function (VRF) and supports cross-shard communication for seamless interaction between shards. The blockchain is EVM-compatible, allowing Ethereum developers to easily port their dApps. Harmony gained attention for its Horizon Bridge, though the bridge suffered a significant exploit in June 2022. The team has since focused on recovery efforts and continued development. The ecosystem includes DeFi protocols, NFT platforms, and gaming projects across its sharded architecture. ONE token is used for staking, governance, and transaction fees.

Crypto Staking

ONE token holders can delegate to validators through the Effective Proof of Stake system, which distributes rewards more evenly and promotes decentralization among validators.

EVM Blockchains

Harmony is fully EVM-compatible, allowing seamless deployment of Solidity smart contracts and integration with standard Ethereum development tools and wallets.

L1 Blockchains

Harmony is a sharded Layer 1 blockchain using Effective Proof of Stake consensus with two-second finality, random state sharding, and cross-shard communication for scalable dApp deployment.

Harmony is a Layer 1 blockchain that pioneered sharding technology for scalability, utilizing an Effective Proof of Stake (EPoS) consensus mechanism designed to reduce stake centralization. The network offers EVM compatibility, enabling developers to deploy Ethereum-based dApps with significantly lower fees and faster 2-second finality. Harmony's staking model is noteworthy for its democratic approach, distributing rewards more evenly across validators to prevent whale dominance. However, the project suffered a devastating blow in June 2022 when its Horizon Bridge was exploited for approximately $100 million, severely damaging trust and ecosystem momentum. Recovery has been slow, with TVL and developer activity declining substantially. The team's handling of the bridge hack drew community criticism, and the ecosystem has struggled to regain traction amid fierce L1 competition from chains like Solana and Avalanche. While the underlying technology remains sound, diminished network activity, reduced market confidence, and an uncertain roadmap present significant concerns. Investors should weigh the innovative EPoS design against the project's troubled recent history and competitive headwinds.
