Embodiment Construction
[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] For ease of understanding, let’s first introduce the concepts of blockchain and smart contracts.
[0021] Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In layman's terms, the blockchain is a general ledger that records all historical transactions, and each block contains several transaction records. If a...

The embodiments of the present invention provide a method and device for processing rule change of a smart contract. In the method, one of the users who formulate a smart contract uses a rule engine to generate business rule related information to be changed and deploy it to a rule running server. The rule running server The blockchain gateway is then called. After receiving the information confirming the change from all the participants, the blockchain gateway sends the relevant information of the changed business rules to each node, so that each node can save it in their respective ledger. The method provided by the embodiment of the present invention can integrate a business rule engine in a smart contract, so that business personnel can conveniently and simply formulate business rules. After formulation, business rules can be saved in the blockchain ledger. In addition, changes to business rules must be confirmed by all relevant parties before business rules can be updated, thereby avoiding malicious tampering of business rules and improving transaction security.
Description
technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a method and device for processing rule change of a smart contract. Background technique [0002] Blockchain technology provides a trust framework that we can use to execute business processes securely and automatically in a multi-party transaction scenario. [0003] In traditional blockchain platforms, we usually write business processes and business rules into smart contracts and execute them automatically during the transaction process. In a multi-party transaction scenario, the business rules of smart contracts usually require business personnel to determine the business logic. However, in the process of realizing the invention and creation, the inventor found that the current business rules are written by developers, and business personnel cannot participate in the development of smart contracts. When business rules need to be changed, busin...
