Abstract

The invention provides a method and device for switching fragment nodes in a block chain system. According to the method, the block chain system comprises a first fragment and a second fragment, the first fragment comprises a first fragment node, the first fragment node has a corresponding first standby node, the first backup node is synchronized with first state information generated by the first fragment node in the process of executing a first block, each second fragment comprises a second fragment node, the method is applied to the first backup node, and the method comprises the following steps that cross-fragment information is received from the second fragment node, on the basis of the first state information and the cross-fragment information, the first block is continuously executed instead of the first fragment node. Therefore, continuous proceeding of the process of the block chain system is ensured, and the performance and availability of the block chain system are improved.

Description

technical field [0001] One or more embodiments of this specification relate to the field of blockchain technology, and in particular to a method and device for switching shard nodes in a blockchain system. Background technique [0002] Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. characteristics such as. Blockchain technology has great application potential in scenarios such as finance, public welfare, justice, and transactions. [0003] At present, a very important factor that restricts the large-scale application of blockchain technology is performance, mainly including throughput, which can generally be measured by the number of transactions per second (Transaction Per Second, referred to as TPS). Developers have come up with various schemes to try to increase the throughput of blocks, a process known as "scaling". Blockchain sharding technology...
