How to buy Japan Open Chain (JOC)

How to buy and use Japan Open Chain (JOC) on its native network

Japan Open Chain (JOC) is an EVM-compatible Layer 1 public blockchain launched in 2024. It is designed for business use and operates under Japanese legal and compliance standards. The network aims to balance decentralization with scalability to support corporate and financial institutional needs.

Verified routes to get JOC

JOC can be acquired through several centralized exchanges. The available pairs include both USDT and JPY.

• MEXC offers a JOC/USDT pair with a trading fee of 0.
• Zaif provides a JOC/JPY pair.
• Gate lists a JOC/USDT pair.
• BitTrade offers a JOC/JPY pair.

KYC requirements and account features vary by country. Users should check their local availability before opening an account.

What the native network does

The JOC network uses a Proof of Authority (PoA) consensus algorithm. This means the chain is operated by a group of trusted validators. These validators include Japanese corporations and institutions such as the Sony Group, NTT Group, and Dentsu Group, as well as leading universities.

The network is Ethereum-compatible. This allows it to execute smart contracts and ERC-20 token transfers. For simple gas token transactions, the network can reach 2,000 transactions per second. Complex smart contract executions achieve approximately 400 transactions per second.

The project aligns with Japan's LDP policy, which supports the use of yen stablecoins and 24/7 programmable settlement. This is intended to provide a regional settlement alternative in Asia.

Wallet, transfer, and network-fee checks

Because JOC is EVM-compatible, it can integrate with tools that support the Ethereum Virtual Machine. However, users must verify that their specific wallet or exchange supports the JOC network before initiating a transfer.

To verify addresses and track transactions, users can use the official explorer. For those who want to inspect the implementation activity, the source code is available on GitHub. Technical specifications and project goals are detailed in the whitepaper.

Self-custody and withdrawal risks

Moving assets from an exchange to a private wallet carries risks if the network is not correctly identified. Deposit and withdrawal support for the exchanges listed above is not verified. Users should not assume that every exchange supports deposits and withdrawals for the same network.

There are also risks related to regional restrictions. Exchange availability and withdrawal limits depend on the user's country. Always verify the withdrawal network on the exchange interface before sending funds.
