Revenue model
- Gas Fees (Transaction Fees): JOC token functions as the gas token for the network. Users pay gas fees in JOC for all transactions including smart contract execution and token transfers. The fees are extremely low (sub-1 yen per transaction), enabling high-frequency and micropayment use cases.
- JOC Coin Trading on Exchanges: JOC coin is listed on domestic Japanese crypto exchanges (Zaif) and international exchanges (Gate, MEXC), serving as both a utility token for gas fees and a tradeable cryptocurrency asset.
