Cortex is a decentralized AI autonomous system. The blockchain wants to make AI consensus available for contracts. Traditional EVM is not able to run a smart contract on full node with complex inference computation, since the computational load is too heavy on CPU for a full node. The Cortex VM enables those inference instructions running on GPU / FPGA. The model conversion between different framework, like TensorFlow or MXNet, would be done by the team. The fee for a contract using those inference instruction set is going to be designed for GPU / FPGA. The team will also provide a basic model zoo with world class quality. The project is founded by a group of hardcore veteran in blockchain field. The technical stack and knowledge reside in blockchain and machine learning, both the team members and advisor groups are top tier in the industry. They rethink and redefine the question that what would be a strong endorsement for a currency, meanwhile, the real "intelligent" smart contracts will be implemented.
