The XI protocol implements a decentralized supercomputer through cascading computation, which is used for the final correct meta prediction. By using XI staging and Oracle commit level patterns to implement sequential anti witch and computing phases, this architecture outsources multi agent distributed consensus.The application of the XI protocol includes the utility of purchasing time on satellite advertising and the utility of rewards for solving open mathematics problems. XI Protocol aims to establish an interstellar decentralized platform, provide financial incentives for outsourcing truth prediction, and participate in the new economic model for question and answer....
