Description
Technical field
The present invention relates to block chain field, in particular to a kind of legal electronic money issuing system based on block chain.
Background technique
Block chain is the novel of the computer technologies such as Distributed Storage, point-to-point transmission, common recognition mechanism, Encryption Algorithm
Application model.
For narrow sense, block chain is a kind of be sequentially in time combined into data block in such a way that sequence is connected one
Kind linked data structure, and the distributed account book that can not be distorted He can not forge guaranteed in a manner of cryptography.Broadly, area
Block chain technology is to verify to know together algorithm with storing data, using distributed node to generate and more using block linked data structure
New data, utilizes the intelligence being made of automatized script code at the safety for guaranteeing data transmission and access in the way of cryptography
Can contract program the completely new distributed basis framework and calculation of one kind with operation data.
Block chain is to distort that cost is big compared to the advantage of traditional book keeping operation mode, and data have high Feasible degree,
It can reduce reconciliation cost using with banking system.
In the prior art, block chain technology is disadvantageous in that: the existing electronic money based on block chain is not supervised
Pipe, is readily applied to the criminal offences such as money laundering.
Summary of the invention
In view of the above drawbacks of the prior art, technical problem to be solved by the invention is to provide one kind to be based on block chain
Legal electronic money issuing system, it is desirable to provide a kind of distribution scheme of legal electronic money, be convenient for state supervision, improve goods
