Problems solved by technology

[0003] The first method above uses SDK integration, and its main disadvantages are: high learning and development costs, SDK toolkits generally only support mainstream development languages ​​such as Java, Go, Nodejs, etc. If the business system uses other development languages, integration is more difficult
[0004] The second method uses the alliance operator (for example, Fabric network, Hyperchain (hyperchain) network), and its disadvantages are: the private key is not local to the participant, and there may be cases where the platform maliciously forges the transaction of the participant, and the participant has no information on the chain. Digital asset controls are weak

Abstract

The invention discloses a blockchain node access method, device and system. The method comprises the steps: receiving operation information from a service system, the operation information comprisingoperation contents and operation types; in response to the job type indication, executing a data encryption operation, According to pre-configured block chain node information, encrypting the job information according to a pre-generated local private key and then sending the job information to a predetermined block chain node so as to execute a corresponding job operation; and receiving response information returned from the blockchain node, and sending the response information to the service system. Through the embodiment of the invention, the transaction safety can be improved.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a block chain node access method, device and system. Background technique [0002] At present, one way for the business system to access the blockchain network is to integrate the SDK (Software Development Kit) provided by the underlying technology platform. When completing an on-chain transaction, it is generally necessary to specify the Block chain network address and related signature private key, construct on-chain transaction, perform transaction signature, call and send transaction interface and other operations. Another access method is the alliance operator. The alliance operator provides a general access platform or access gateway, hosts the user's private key, and the business system directly calls the corresponding upper-level business interface to complete the interaction with the blockchain network. [0003] The first method above uses SDK integration. Its main d...
