Problems solved by technology

This kind of consistency is only the consistency at the data level, and has no ability to identify and process the impact of data changes on the business level; although smart contracts can encapsulate logic, the logic processed by smart contracts is often only business logic. There is no ability to deal with changes; for example, in a digital asset transaction scenario, the business needs to pay attention to transaction participants who have submitted more than 100 transactions within 10 minutes. This kind of problem cannot be solved by the traditional blockchain system

Embodiment

[0036] Since the implementation details of different blockchain systems will be different, the following takes a business scenario in which more Fabrics in an enterprise implement a transfer logic as an example to illustrate the implementation details and logic of the method of the present invention.

[0037] The process is as follows:

[0038] 1. Realize the block code (Chaincode) according to business abstraction and logic. This block code includes an asset named Token, a participant object User and a transaction logic named transfer, that is, transfer a specified amount (amount) from a User A Token to another User B;

[0039] 2. Deploy the block code to Fabric;

[0040] 3. The metadata analysis component analyzes the block code to obtain the attributes and names of the Token, User and its transfer records defined in it;

[0041] 4. Define a monitoring rule: if a user transfers more than 1w amount within 30 minutes, a SMS alarm will be triggered;

[0042] 5. Participants ...

Abstract

The invention discloses a block chain-based asset monitoring method. The method comprises the following steps of: associating a stream computation engine for each participator node in a block chain network; realizing an intelligent contract according to a business and deploying the intelligent contract onto the block chain network; adding metadata analysis components on the participator nodes; defining rules and corresponding response actions in the stream computation engines; submitting lamination proposals to the block chain networks by participators through corresponding nodes; verifying and executing the proposals by the block chain network; recording an execution result of the intelligent contract into an account book copy by each participator node and then sending an event to the associated stream computation engine; and processing the events by the stream computation engine according to the predefined rules. According to the method, the block chain main networks do not need to be changed and the working processes of the block chain networks are not changed; and authorization mechanisms of the original block chain networks are perfectly compatible, and each stream computationengine only needs to read a data set belonging to the stream computation engine, so that asset problems can be recognized in real time or quasi real time.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to an asset monitoring method based on block chains. Background technique [0002] With the popularization of blockchain technology, blockchain-based systems are gradually being applied to various business scenarios. Using blockchain systems often manages the mapping of various assets, digital assets or real assets. For the management and monitoring of assets, the traditional blockchain system only solves the problem of data consistency, but does not solve the problem of monitoring, which is specifically reflected in: most of the traditional blockchain systems are just a distributed system that can be used for common bookkeeping, that is, The same processing logic (smart contract) and the same data (ledger) are guaranteed between the participating parties (participating nodes). This kind of consistency is only the consistency at the data level, and has no ability t...
