Japan Open Chain

Japan Open Chain (JOC) is an enterprise-grade Layer 1 public blockchain built to meet the needs of enterprises, financial institutions, and local governments within a regulatory environment. Underpinned by Proof-of-Authority consensus and anchored in Japanese legal jurisdiction, JOC provides a reliable and enterprise-friendly platform while preserving Ethereum compatibility.

It’s not aiming to chase DeFi or yield farming hype. Instead, it’s built to enable mission-critical use cases—stablecoin issuance, municipal digital IDs, branded NFTs—that demand legal certainty, stability, and throughput.

Technical Highlights

• EVM Compatibility
  Japan Open Chain is fully compatible with the Ethereum Virtual Machine, meaning developers can use standard tools like Solidity, Remix, Hardhat, and Metamask without modification.

• Proof-of-Authority Consensus
  Unlike Proof-of-Work or Proof-of-Stake, PoA enables fast block times, low energy consumption, and deterministic validator sets — critical for compliance and performance.

• Transaction Performance
  The network achieves approximately 400 transactions per second for smart contract operations, and up to 2,000 TPS for simple token transfers, such as stablecoin settlements.

• Security and Legal Clarity
  Each validator operates under Japanese corporate law, adding legal accountability and making the chain suitable for regulated financial products, e-governance, and enterprise services.

Use Cases and Ecosystem

Japan Open Chain is designed around real-world deployment — not theoretical models. It’s already seeing traction in several pilot programs:

• Stablecoin Issuance
  Several Japanese banks are testing and preparing to issue legally compliant, fiat-backed stablecoins (such as the aJPY) directly on the network.

• Municipal Programs
  Local governments are issuing NFT-based residency credentials and identity certificates — like the e-Kaga citizen ID — for digital public services.

• NFT-based Regional Development
  Programs like Yamanobe Town’s art initiative use NFT collectibles to drive cultural participation and tourism.

• Enterprise Loyalty & Web3 Onboarding
  Corporations are exploring branded token issuance, voucher systems, and integration with employee benefit platforms.

• DeFi-Adjacent Finance
  Lending programs based on stablecoin flows are being trialed with interest rates tied to token collateral rather than speculative yield farming.
