OpenLedger

What is OpenLedger (OPEN)?

OpenLedger describes itself as an AI blockchain, infrastructure for training and deploying specialized AI models using community-owned datasets. Uploads of data, model training, reward credits and governance are recorded on-chain. In July 2024 the project announced an $8 million seed round led by Polychain Capital and Borderless Capital, and the OPEN mainnet launched in November 2025.

The OPEN ticker is shared by other projects, so make sure you are looking at the AI blockchain described here, whose official site is listed below. Its documentation says contributors, model builders and token holders all take part in the network through on-chain rules.

How OpenLedger works

The network is built around attribution: tracing which data shaped a model's answer so that contributors can be rewarded.

• Datanets: community-curated datasets. Contributions are verified, recorded on-chain and rewarded according to attribution.
• Model training: users can train and fine-tune specialized models on their own data or on Datanet data.
• Inference and attribution: outputs from a chat, task or API call can be traced to the model used, its training data and its contributors, who receive rewards.
• Governance: a hybrid on-chain process built on OpenZeppelin's modular Governor framework, in which OPEN holders take part.

OPEN supply and token design

OPEN is the network's native token. Binance Research describes it as the gas token, used for inference fees, model access, staking and Datanet usage, with governance rights for holders. The total and maximum supply is 1 billion OPEN. A Binance HODLer Airdrop allocated 10 million OPEN, or 1% of supply, at the Binance listing in September 2025, when only a fraction of the supply was freely tradable.

The token exists as an ERC-20 on Ethereum and as a BEP-20 on BNB Chain. Use the contract addresses published on the official site and docs, since several unrelated tokens share the OPEN ticker. Live circulating supply is shown in the market data on this page.

What to check before using OPEN

• Attribution-based AI rewards are a new idea, and real demand from model builders and data contributors is unproven.
• Only part of the supply was tradable at listing, so unlocks of team, investor and ecosystem allocations may follow.
• The OPEN ticker is shared. Verify the project name and contract before buying.
• AI and data-ownership projects face evolving rules on data rights and licensing.
• Network and bridge details differ across chains, so smart contract and bridging risk apply.
