Embodiment Construction

[0023] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described The examples are some of the examples in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of this specification.

[0024] At present, a very important factor that limits the large-scale application of blockchain technology is performance, that is, throughput, which can generally be measured by the number of transactions per second (Transaction Per Second, TPS). Developers have come up with various schemes to try to increase the throughput of blocks, a process known as "scaling". In t...

Abstract

The embodiment of this specification provides a method and device for exiting a cross-shard transaction in a blockchain system. The method includes: determining whether to exit the cross-slice transaction according to the exit time information corresponding to the cross-slice transaction; In the case of the cross-shard transaction, instruct the source shard and the target shard corresponding to the cross-shard transaction to exit the cross-shard transaction.

Description

technical field [0001] One or more embodiments of this specification relate to the field of blockchain technology, and in particular to methods and devices for exiting cross-shard transactions in a blockchain system. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed non-tamperable and unforgeable distributed ledger. Due to the characteristics of decentralization, non-tamperable information, and autonomy, the blockchain has also received more and more attention and application. [0003] Blockchain sharding technology is a solution for expanding the blockchain. The basic idea of ​​blockchain sharding is to divide the nodes in the blockchain network into several relatively indep...
