Embodiment approach

[0045] Step S301: the first node 100 calls the log contract to store the target log in the log in the form of a key-value pair

[0046] The specific implementation of the storage target log in the embodiment of the present invention is not limited, and three possible implementations are shown below.

[0047] In one implementation, the log contract uses the user ID of the target user as the key of the key-value pair, the first node

[0050] It should be noted that the above-mentioned several specific implementations of step S202 of the present invention can be implemented independently, or

[0051] Optionally, the log contract can encrypt the target log, and use the key corresponding to the target log to decrypt,

[0052] Step S302: the monitoring DAPP in the first node 100 regularly obtains the data of the first node 100 from the log system 300

[0054] Step S303: The monitoring DAPP in the first node 100 identifies the target log of the first node 100, and performs abnormality ide...

Abstract

Embodiments of the present invention provide a blockchain-based information early warning method, device, related nodes, and storage medium, wherein the method includes: identifying a target log of a first node to obtain abnormal information; broadcasting the abnormal information to the blockchain network to record the abnormal information in each blockchain node of the blockchain network; receive at least one block in the blockchain network except the first node The broadcast information sent by the chain node; if the broadcast information sent by n of the blockchain nodes is the same as the abnormal information, the early warning system will be triggered to issue an abnormal alarm for the abnormal information. By implementing the present invention, the target log can be quickly queried, abnormal information can be obtained, and when the broadcast information sent by n blockchain nodes is the same as the abnormal information, an early warning system can be triggered for early warning.

Description

Blockchain-based information early warning method, device, related nodes and storage medium technical field The present invention relates to the technical field of block chain, in particular to a kind of information early warning method, device and phase based on block chain. Joint point and storage medium. Background technique [0002] A smart contract is a computer protocol designed to disseminate, verify or execute contracts in an informative manner, allowing Trusted transactions without third parties. When specifically implemented, the Ethereum platform executes any arbitrary execution through the Ethereum virtual machine. User-defined contract code to implement smart contracts. [0003] At present, the logs related to smart contracts are all saved based on transactions. When querying a user's transaction, usually Query and count according to the hash value of each transaction. It can be seen that the operation of querying and counting transaction logs is very in...
