Abstract

The invention relates to a data processing system based on a directed acyclic graph, and the system comprises a plurality of network nodes which are connected through a network, and the network nodes correspond to user terminals. A distributed record data set is stored in the network nodes, transaction information between the network nodes is recorded in the distributed record data set, the distributed record data set is constructed based on a directed acyclic graph comprising a plurality of vertexes, and the vertexes represent transaction records between the corresponding network nodes; the distributed record dataset is configured to: for each vertex, if one vertex is referenced by another vertex, establish a directed edge between the vertex and the other vertex; the distributed record data set is further configured to verify the transaction record at least based on the credibility of the corresponding vertex under the condition that the transaction record is generated between the network nodes, and make the corresponding network node respond to the transaction record after the verification is passed. According to the processing system, the distributed record data set can be flexibly adjusted, and the transaction data recording and verification efficiency is improved.

Description

technical field [0001] The present disclosure relates to the field of block chains, in particular to a data processing system based on a directed acyclic graph. Background technique [0002] Blockchain is a distributed shared account book and database, which has the characteristics of decentralization, non-tampering, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for the creation of trust in the blockchain. There are network nodes in the blockchain, and each network node has its own records (or accounts), which are consistent with the records of other network nodes. However, the system efficiency of existing blockchains is generally relatively low, which is not conducive to the large-scale expansion of blockchain systems. The fundamental reason is that the blockchain needs to use a consensus mechanism to maintain the chain structure of the data, which is difficult to implement in a distribu...
