概要

Harmonyはレイヤー1ブロックチェーンで、Effective Proof of Stake(EPoS)コンセンサスとステートシャーディングを使用してスケーラビリティと分散化を実現します。このプラットフォームは、2秒のトランザクションファイナリティと低い手数料を備えた分散型アプリケーションの作成をサポートするように設計されました。Harmonyは、検証可能なランダム関数(VRF)を使用したランダムシャーディングを備えており、シャード間のシームレスなインタラクションのためのシャード間通信をサポートしています。ブロックチェーンはEVM互換で、イーサリアムの開発者が簡単に分散型アプリケーションを移植できます。HarmonyはそのHorizon Bridgeで注目を集めましたが、このブリッジは2022年6月に重大なエクスプロイトに見舞われました。チームはそれ以来、リカバリー努力と継続的な開発に焦点を当てています。エコシステムには、シャード化されたアーキテクチャ全体にDeFiプロトコル、NFTプラットフォーム、ゲームプロジェクトが含まれています。ONEトークンはステーキング、ガバナンス、トランザクション手数料に使用されます。

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.
