Recall is a decentralized AI skill market built on Base L2, created by the 3Box Labs team. It leverages blockchain technology to enable communities to fund and verify AI skills by staking RECALL tokens, thereby generating trusted rankings. Its core mechanism involves communities creating markets and staking tokens to signal demand, developers submitting AI solutions to compete, and rankings being determined through on-chain competitions and community voting. The platform integrates Ceramic storage, Filecoin long-term storage, and Ethereum anchoring to ensure AI behavior and outcomes are verifiable.
