OpenLedger ($OPEN )is a blockchain project focused on decentralizing AI development and data economy by integrating attribution, transparency, and tokenized incentives. The native token $OPEN is built on ERC‑20 standards with a total supply of 1 billion tokens, and its utility spans gas/transaction fees, governance, staking, and reward distribution to data contributors and model developers through a “Proof of Attribution” framework. [2] OpenLedger’s architecture is EVM‑compatible and built as an Optimism‑based rollup (OP Stack), enabling interoperability with Ethereum tooling, wallets, and bridges. One of its distinguishing features is the emphasis on making AI data and models “liquid assets” meaning contributors who provide datasets or code that influence model outputs are rewarded in OPEN tokens proportionally via on‑chain attribution. The project has secured funding (e.g. $15 million in pre‑launch investments) and prepared for its token launch and mainnet deployment in September 2025, with strong testnet metrics (millions of nodes, tens of millions of transactions, and thousands of models developed)
