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 the time period with many concurrent transactions (such as the Double Eleven period), the access pressure of a single chain increases, making the processing of a single chain unable to meet business needs

Embodiment Construction

[0062] Embodiments of this specification will be described below with reference to the accompanying drawings.

[0063] 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, a plurality of 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 im...

Abstract

The embodiment of the invention provides a method and device for deploying a contract in a block chain system. The block chain system comprises N mutually independent block chains, the method is executed by a block chain platform, the block chain platform is connected with the N block chains, and the method comprises the following steps: receiving a first request for deploying a first contract; determining that a first contract corresponds to a first block chain in the N block chains based on a predetermined rule; and sending the first transaction to the first block chain to deploy the first contract to the first block chain.

Description

[0001] This application is a divisional application of the invention patent application with the application number 202011176391.4 filed on October 28, 2020, entitled "Method and Device for Deploying and Calling Contracts in the Blockchain". technical field [0002] The embodiment of this specification relates to the field of blockchain technology, and more specifically, to a method and device for deploying a contract in a blockchain, and a method and device for invoking a contract in a blockchain. Background technique [0003] 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 pl...
