The block chain is widely applied to the aspects of trusted transmission of data, use history tracing and the like by the characteristics of data tamper resistance and repudiation resistance, and is applied to more and more fields. While the block chain technology is widely used, the block chain supervision problem also comes along.
The block chain supervision modes are currently divided into two modes, one mode is institutional supervision, namely, a supervisor is added into the block chain as a node and used as a legal and nominal endorsement; the other is technical supervision, one is that the supervisor is used as a super account in the block chain, all actions in the block chain are transparent to the supervisor, and once illegal actions exist, an alarm condition is triggered, and the supervisor takes corresponding measures; and the two supervisors are used for auxiliary monitoring, and whether the transaction on the chain is reasonable and legal is monitored through data such as logs, behavior records and the like reported by the block chain, and corresponding measures are taken after an alarm condition is triggered. Both of these ways supervise the behavior of the on-chain transaction, and there is no practical and effective means for monitoring the behavior of the block chain on the uplink data. For an operator of a block chain, although the block chain is in distributed storage, the deployment of block chain nodes on cloud resources may cause that nodes of the whole block chain are in a machine room or even a physical machine, and the deployment of the nodes is still centralized at this time, so that data on the block chain is still likely to be tampered at this time, and the above two supervision methods cannot be applied to solve the problem, and therefore a supervision method is needed to supervise the security of uplink data.
