Abstract
Novel technical ways of analyzing a blockchain system using machine learning are presented. In various embodiments, A system can deploy, by a first entity, a policy smart contract on a blockchain to analyze a first smart contract deployed by a second entity, wherein the policy smart contract is governed by a set of rules, wherein the policy smart contract performs a first assessment that includes analyzing a set of functionalities of the first smart contract and detects a set of vulnerabilities associated with the first smart contract based on the set of rules. The system can determine at a first time a risk score corresponding to the first smart contract based on the analyzing and the detecting. In response to determining that the risk score is above a threshold score, the system can restrict users of a first platform corresponding to the first entity from accessing the first smart contract.
