Claim 3:
4. The method for assessing SOTIF of autonomous driving based on DAG block chain according to claim 1, wherein in the step 2, the process of the transaction comprises the data transmission in the in-the-loop test being created as a transaction in real time; a data structure of TX possesses mainly six attributes, including an id of the transaction, a hash value of first two transactions verified by the transaction, the data of the transaction, number of times of the transaction being verified by subsequent transactions, and a hash value of the transaction; the data in the transaction process is encrypted by using a symmetric key, the manager is responsible for distributing and managing the key; after the key is distributed, the transaction is initiated, and the two transactions having been connected to the DAG chain are verified by the initiated transaction, which is a process of transaction verification; the transaction is written into the DAG chain after the transaction verification is successful; in response to the nodes of a last transaction that are not verified by any other transactions, the transaction path is backtraced, and the credit incentives and the credit penalties for the nodes are imparted according to a credit assessment rule.
