Problems solved by technology

However, the blockchain forms a network in the form of nodes. Each node integrates a kv-type database and has a complete data ledger. Access to data can only be realized through smart contract interfaces.
There are two disadvantages in this data access mechanism: first, when the smart contract does not implement the required data query function, the world state data will not be available, which is not conducive to system operation and maintenance and business support; Write the code to view the world state data in the contract. These non-business function-related codes are integrated in the smart contract, which not only leads to a lot of code redundancy, but also is not conducive to the upgrade and maintenance of subsequent smart contracts

Abstract

The present application provides a method for directly accessing the state of the blockchain world and a blockchain node. The method includes: receiving a request message and verifying the identity of the user corresponding to the request message, wherein the request message includes : user ID, target contract unique identifier, target data key value, data value and signature information; if it is determined that the request type of the verified request message is to query world state data, then the target contract unique identifier and target data key value Splicing into a complete query key value; using the complete query key value to query the world state data of the blockchain. This application can directly access the data of the world state, thereby improving the operation and maintenance support capability of the blockchain system.

Description

technical field [0001] This application relates to the field of blockchain technology, in particular to a method for directly accessing the state of the blockchain world and blockchain nodes. Background technique [0002] Smart contract technology has enabled blockchain applications to expand from a single encrypted digital currency field to other fields, such as supply chain finance, cross-border payments, asset securitization, commodity traceability and digital copyright, etc., which greatly broadens the scope of blockchain applications. In terms of application scope, blockchain technology is setting off a disruptive revolution. [0003] In traditional system deployment, application servers and database servers are generally deployed independently, and data operations can be added, deleted, modified, and checked through database management tools. However, the blockchain forms a network in the form of nodes. Each node integrates a kv-type database and has a complete data l...
