Abstract: A self-adaptive execution method for realizing data trustworthiness includes: starting a smart contract, executing the smart contract and verifying an execution result of the smart contract. A random execution mode based on redundant calculation is employed, and multiple nodes in a network are randomly selected to jointly execute a data analysis logic, thereby realizing trusted computing of an execution result in a relatively distrusted environment and improving an execution efficiency of the smart contract. Meanwhile, by recording the execution of the contract in a process of synchronously calling the multiple nodes, a needed execution record of contract calling is acquired from the node in a latest state and replayed locally when synchronization is needed, so that the random multiple nodes can be quickly recovered when states of the random multiple nodes are not synchronized, realizing high availability of data and satisfying a data analysis scenario with low response time.
