Problems solved by technology

[0004] At present, the number of shards in the blockchain system is often constant. Therefore, when the business on the blockchain grows sharply, the entire system needs to be shut down and manually expanded, which reduces the availability of the system.
However, if a large number of fragments are used in the early stage of the business, it will cause a waste of resources

Abstract

The invention provides a method and a device for expanding a fragment in a block chain system. The block chain system comprises a first fragment, and the first fragment comprises a first node. The method comprises the following steps that a first node receives a capacity expansion request comprising information of a first block to be executed; after the first block is executed, the first node sends a first world state corresponding to the first block to the second node; at least one second block is executed, and each piece of state change information corresponding to each second block is recorded; after the first world state is sent, the first node sends each piece of state change information to the second node; the second node belongs to a second fragment to be added into the block chain system; and the second node obtains the initial world state of the second fragment based on the received first world state and each piece of state change information. Therefore, automatic capacity expansion of the block chain system is realized, and the problem that the number of fragments in the block chain system cannot be dynamically expanded along with increase of the number of transactions is solved.

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 expanding the capacity of fragments 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] At present, a very important factor that limits the large-scale application of blockchain technology is performance, which mainly includes throughput, which can generally be measured by the n...
