Japan Open Chain is an EVM-compatible blockchain run by a Japanese consortium with a permissioned validator set, offering fast, low-cost transactions and Japan-focused regulatory compliance.
Japan Open Chain (JOC) is an EVM-compatible public mainnet operated by a consortium of Japanese enterprises using Proof‑of‑Authority (IBFT) for fast finality and compliance-ready operations. Core use cases include bank‑issued stablecoins under Japan’s revised Payment Services Act, enterprise NFTs/ticketing, loyalty and points tokenization, and supply‑chain provenance. Typical performance observed on public explorers shows low‑seconds block times (~2–3s), sub‑cent average gas costs, and throughput in the hundreds of TPS, with growing activity from enterprise pilots.
Japan Open Chain is unique for its Japan‑based, named validator consortium and PoA (IBFT) governance that emphasizes regulatory compliance, auditability, and predictable operations—features many public EVM networks don’t prioritize. It retains full Ethereum tooling compatibility while delivering practical performance (≈2–3s blocks, <$0.01 average gas, hundreds TPS), making it suitable for production fintech and government‑adjacent workloads. This blend of compliance, enterprise SLAs, and low‑cost throughput is particularly compelling for yen‑stablecoin issuance and large‑scale consumer Web3 services compared with higher‑fee, slower‑finality L1s.
