Yes, Ethereum can support the operation of distributed AI networks. Its blockchain provides a decentralized, secure, and transparent platform for executing smart contracts, which can manage AI model training, data sharing, and computation across nodes. Ethereum's infrastructure, with its ability to handle complex computations and store data on-chain or via IPFS, enables distributed AI networks to function efficiently. Projects like SingularityNET already leverage Ethereum to create decentralized AI marketplaces, allowing AI services to be shared and monetized securely. However, scalability and gas fees remain challenges, though layer-2 solutions like Optimism or upcoming upgrades may mitigate these. Ethereum’s robust ecosystem and developer tools make it a viable choice for distributed AI, fostering trust and interoperability.
