Problems solved by technology

In the second type of blockchain network, the nodes that need to query the data block information on the blockchain perform queries on the blockchain through the corresponding bookkeeping nodes, since all bookkeeping nodes have the authority to query the information on the blockchain The detailed information in all data blocks on the blockchain, the nodes that need to query the data block information on the blockchain can query the detailed information in all the data blocks on the blockchain, for enterprises that need to keep the information on the chain confidential Unable to keep information confidential
[0004] The existing technology lacks a scheme that can protect the privacy of the data on the chain on the basis of sharing information to reach a consensus

Abstract

The invention provides a method for inquiring transaction information in a block chain network, an accounting node and a medium. Wherein the block chain network comprises an accounting node sub-network and a service node sub-network. The method is performed by one accounting node in an accounting node sub-network. The method comprises the following steps: receiving a query request of a business node for transaction information in a data block; Obtaining authority data of the service node from an intelligent contract of the service node and the block chain operator; And if it is determined thatthe business node has a query permission for the transaction information according to the permission data of the business node, returning the transaction information to the business node, otherwise,returning a hash value of the transaction information to the business node. According to the embodiment of the invention, on the basis that the shared information achieves the consensus, privacy protection can be carried out on the uplink data.

Description

technical field [0001] The present disclosure relates to the field of blockchain, and in particular to a method for querying transaction information in a data block in a blockchain network, an accounting node and a medium. Background technique [0002] There are two types of traditional blockchain networks. In the first type of blockchain network, each accounting node is also a node where transactions occur and transaction information needs to be uploaded to the chain. In the second type of blockchain network, the accounting nodes are only responsible for accounting on the blockchain, that is, the data is uploaded to the chain, and the nodes that actually occur transactions and need to upload transaction information to the chain are outside the accounting nodes. When the transaction information needs to be uploaded to the chain, the node that needs to upload the transaction information will send the transaction information that needs to be uploaded to the corresponding book...
