Problems solved by technology

However, in the case of a single chain, a large amount of stored data has been accumulated over a long period of time, and the account size is getting larger and larger, which reduces the processing capacity of the single chain
In addition, during times when there are many concurrent transactions (such as Double Eleven), the access pressure of a single chain increases, making the processing of a single chain unable to meet business needs

Embodiment Construction

[0036] Embodiments of this specification will be described below with reference to the accompanying drawings.

[0037] figure 1 A schematic diagram of a blockchain system according to an embodiment of this specification is shown. Such as figure 1 As shown, the blockchain system includes a blockchain platform 11 and multiple user terminals (user terminals 12, 13 and 14 are schematically shown in the figure), and the blockchain platform is a blockchain platform server. The user terminal is connected to the blockchain platform 11, and operates the blockchain through the blockchain platform 11. The blockchain platform 11 is connected to multiple mutually independent blockchains, figure 1 Block chain 1, block chain 2 and block chain 3 are schematically shown in . Blockchain 1, blockchain 2, and blockchain 3 can be called parallel chains of a blockchain system, which operate independently of each other to process user requests and store transaction data separately, thereby impro...

Abstract

An embodiment of the invention provides a method and device for querying data in a blockchain system, wherein the blockchain system comprises N mutually independent blockchains. The method comprises the steps that a query request for first data is received, wherein the query request comprises a first data identifier of the first data; that the first data is stored in a first block chain in the N block chains is determined based on the query request; based on the first data identifier, the first data is read in the first block chain.

Description

technical field [0001] The embodiment of this specification relates to the field of blockchain technology, and more specifically, to a method and device for querying data in a blockchain system. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is a decentralized distributed database technology, which is characterized by decentralization, openness and transparency, non-tamperable and trustworthy. Every transaction in the blockchain will be broadcast to the blockchain nodes of the entire network, and each full node has a full amount of consistent data. In the consortium chain, usually, the user terminal uses the blockchain platform for business processing, such as depositing certificates, transfers, etc. through the blockchain platform. However, in the case of a single chain, a large amount of stored data is accumulated over a long period of time, and the account size is getting larger and larger, which reduces the processing c...
