What is JOC?

Japan Open Chain (JOC) is a Layer 1 blockchain built on Go Ethereum that combines full Ethereum compatibility with a Proof of Authority consensus model operated by trusted Japanese enterprises. Unlike Layer 2 scaling solutions, JOC operates as an independent chain with 21 validators drawn from major Japanese companies including Sony subsidiaries, Dentsu, and NTT Group. This consortium approach balances developer accessibility through complete EVM compatibility with institutional reliability and regulatory compliance under Japanese law.

JOC provides developers with standard Ethereum JSON-RPC APIs and Debug APIs, making it accessible to the broader Web3 developer community. The network employs Proof of Authority consensus with validators generating blocks at 15-second intervals, achieving finality through validator signature majorities. The platform serves as infrastructure for regulated financial applications including stablecoins, remittance systems, and enterprise NFT projects, while maintaining core compatibility with Ethereum standards and tooling.

Interacting with JOC's APIs

Japan Open Chain supports standard Ethereum JSON-RPC methods and Debug APIs, enabling developers to use Ethereum's native tools like Web3.js, Ethers, Hardhat, and Foundry without modification. The platform maintains full compatibility with EVM bytecode and accepts transactions formatted according to Ethereum specifications.

The Quicknode Japan Open Chain documentation is continuously evolving as the network undergoes upgrades and changes, so we highly recommend cross-referencing with the official Japan Open Chain documentation for the latest updates and features.

Make JOC API Calls
