Decentralized electronic check method and system

Abstract

The invention provides a decentralized electronic check method and system. The decentralized electronic check method comprises the steps of issuing a check, transferring the check, accepting the check and issuing a custom check. The decentralized electronic check system comprises a signing and issuing module, a transferring module, an acceptance module and a user-defined issuing module. The decentralized electronic check method and system have two core characteristics that: firstly, check transactions can be executed asynchronously step by step; the verification broadcast is confirmed to be completed in a time range (such as a plurality of second-level block periods) which can be accepted by a user from issuing, receiving to verification broadcast, even if the problems of network interruption or witness and the like occur, the verification broadcast can be continuously completed in the next short period, the system pressure is greatly released, and meanwhile, the operation safety is ensured; secondly, the user can issue a user-defined check; system user number has no upper limit, and the types of electronic checks which can be issued in the system have no upper limit; and different types are natural and independent, that is, transaction of various electronic checks is natural and parallel, and the parallel has no upper limit in theory, which means that the system performance has a qualitative leap on the basis of a traditional block chain, and the potential of the block chain can be truly and thoroughly released to energize a user.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a decentralized electronic check system. Background technique [0002] Blockchain technology is one of the hottest technology hot spots right now. The most intense competition in the blockchain field is actually the "main chain" battle. Whoever can become the main chain of the blockchain base layer may become the future giants such as Apple and Microsoft. [0003] In essence, blockchain can be regarded as a distributed database technology. By maintaining the chain structure of data blocks, it can maintain continuously growing and tamper-proof data records. Since the launch of Bitcoin, various blockchain projects have emerged one after another, promoting the innovation and progress of blockchain technology. Melanie Swan divides blockchain applications into blockchain 1.0, 2.0, and 3.0 according to the application scope and development stage. Among them: blockchain...

AI Technical Summary

Problems solved by technology

At the beginning, in order to establish a stable digital currency system, Ethereum still used PoW, and later transitioned from PoW to PoS through a hard fork, but due to various problems, the PoS plan was delayed, and it is still a complete PoW

There are many problems in Ethereum: (1) The transaction speed is slow

But when the network is congested, it often takes more than ten hours to confirm

(2) High cost

(3) Network congestion

(4) The Ethereum Virtual Machine (EVM) is highly coupled with the network, inflexible and difficult to upgrade

(5) Smart contracts cannot be modified, and there are security holes

For example, the consensus process based on PoW is a waste of energy, the transaction speed is slow, and there is a 51% computing power attack problem; PoS introduces the N@S attack problem when the block is forked, and the consensus of the network is dominated by a small number of wealthy accounts

[0012] (2) Expansion problem

The capacity of a block is small, and the information stored is limited. Movies, music pictures, big data, etc. cannot run on the blockchain now. Even Bitcoin or Ethereum store very limited transaction information, which leads to Network congestion, slow transactions

Moreover, it is very difficult to simply increase the block capacity. Regardless of the upper limit of the block data structure, increasing the block capacity will inevitably cause a hard fork. This involves another issue of blockchain technology. Data changes in the blockchain system are related to It is very difficult to change the program. Once the system foundation is not solid, it will be difficult to migrate and maintain

The problem of capacity expansion is an important problem that needs to be solved urgently in the current blockchain technology. In addition to traditional capacity expansion and PoS, Segregated Witness, sharding technology, off-chain, and plasma are all trying to solve the problem of capacity expansion, and the specific effects have yet to be verified.

[0013] (3) Safety issues

Existing blockchain projects still have security issues such as privacy protection and private key storage, and there are loopholes in the blockchain software itself, such as smart contract vulnerabilities, which may be exploited by hackers and attacked; the existing consensus algorithm is in There are hidden dangers in mathematics, etc.

[0014] (4) Commercial issues

Most of the projects are in the trial stage, there are a lot of bubbles in the market, and no perfect landing scene can be found
