Description
Technical field
The present invention relates to a kind of quick common recognition bookkeeping methods based on block chain alliance chain and system.
Background technology
With the development of block chain technology and maturation, its number of applications and scene are sharply increased.Block catenary system is according to application
The difference of scene and design system, is generally divided into publicly-owned chain, alliance's chain and proprietary chain.Wherein：
Each node of publicly-owned chain freely can be added and exitted network, and participate in the read-write of data on chain, during operation with
Flat topological structure interconnects, and the service end node of any centralization is not present in network.
Each node of alliance's chain generally has corresponding physical mechanism tissue, by that could add and exit after mandate
Network.The related alliance of each organization's composition interests, safeguards the health operating of block chain jointly.
The write-in authority of each node of proprietary chain takes internal control back, and it is selectively right to read the visual demand of authority
Outer opening.Proprietary chain still possesses the universal architecture of block chain multinode operation, it is adaptable to the internal data management of particular organization
With audit.
Each node in block chain is connected by mechanism of knowing together, and common recognition mechanism is to realize different nodes in block catenary system
Between set up trust, obtain rights and interests mathematical method.
Compared with publicly-owned chain, the characteristics of alliance's chain has oneself：There is certain node quantity, but may not be too many,
Each physical mechanism tissue has the wish of active maintenance system and each has the interests of oneself hectare to based on above feature in public affairs
There are the common recognition mechanism such as POW, POS, DPOS for being run on chain, be poorly suitable for alliance's chain, this shows following two aspects：
(1) total system of alliance's chain, which calculates power, huge can not be large enough to resistance from the increased huge calculation privately of some node
Power is attacked so that POW common recognitions are not suitable for alliance's chain.
(2) the related each side of interests in alliance's chain, it is possible to the interests of the small mechanism of eroded section of interests alliance can be formed, just
The common recognition mechanism such as sharp POS, DPOS is not suitable for alliance's chain.
Therefore, current alliance's chain generally uses the PBFT common recognition mechanism with Byzantine failure tolerance ability in common recognition mechanism,
The mechanism is using license ballot, the common recognition mechanism that the minority is subordinate to the majority is kept accounts come election leadership person, with the strong supervision of permission
Node is participated in, and possesses authority classification ability, performance is higher, is consumed energy lower, and allows 33% node to do evil.The appearance of the mechanism
Wrong ability brings complexity simultaneously, and the common recognition time it is long the problem of, this causes each trade confirmation to wait for a period of time,
Compared with current centralization transaction platform second level confirms, strong influence Consumer's Experience.
