Problems solved by technology

[0004] However, the current blockchain system adopts a single blockchain structure, and each node participating in it needs to store all historical transaction data. The amount is also larger, and the demand for data storage space and computing power of a single node is getting higher and higher; and the scalability of the existing blockchain is poor, and the business is single

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Specifically, the blockchain refers to a technical solution for collectively maintaining a reliable database through decentralization and trustlessness. It is a series of data blocks associated with each other using cryptographic methods. This technical solution mainly allows any num...

Abstract

The invention provides a method and a system for transactions between a main chain and a side chain of a block chain. According to the invention, through the side chain, service types of the block chain can be expanded; by use of a flow dividing mode, transaction quantity of the main chain is reduced; and nodes of the main chain and nodes of the side chain store and verify block data and transaction data of own chains respectively. Thus, data quantity and calculated amount of the transaction are reduced and problems in data storage and expansion of the calculated amount of a single node caused by the fact that different services are supported by the same chain are solved. In addition, by use of a de-centralization scheme, bidirectional anchoring of capitals between the side chain and the main chain can be achieved; multiple side chains are capable of using or anchoring capitals on the same main chain; capital types are reduced; a mutual exchange problem between different capitals is avoided; and the services are quite clear and rational.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and system for transactions between a block chain main chain and side chains. Background technique [0002] Since the launch of the Bitcoin system in 2009, it has brought numerous innovations in computer science and electronic cash, and decentralized cryptocurrencies represented by Bitcoin and its derivative altcoins have received widespread attention. The feature of this currency system is to build a distributed shared ledger based on the block chain, so as to ensure the safety, reliability and decentralization of the system operation. [0003] Blockchain refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. It is a series of data blocks that are associated and generated using cryptographic methods. This technical solution mainly allows any number of nodes in the participating system to associate...
