Description
Technical field
The present invention relates to block chain technical field, in particular to a kind of method for participating in the transaction of block chain with entity identities.
Background technique
After entering the internet stage with human society, because this tool in internet naturally has anonymity, if
There is no the operating main body of corresponding technological means confirmation internet, information security, transaction security is not known where to begin, and but will be caused serious
Governance problem, be seriously unfavorable for society itself development and internet development.Certainly, anonymity itself is also the mankind
One of needs, in many fields such as speech, anonymity is the natural demand of the mankind, but is led in the part such as finance, e-commerce
Domain, more particularly to the field of the end B business, determining proof of identification is the premise of transaction, is not solved these problems, internet exists
The application in these fields can not carry out.In this context, the effort for undergoing numerous computer security experts and society, has been invented pair
Title and asymmetric encryption decryption technology, and on this basis, develop mature social ca authentication system.It has substantially solved mutually
The anonymous risk problem of networking, for modern various banking networks, electronic commerce network etc. is various to be related to the large scale network of transaction
Using having paved road.Human society is allowed to obtain unprecedented prosperity.
2008, the birth of bit coin network allowed this new technology of block chain to appear in face of human society.Based on block
Chain self-technique feature, block chain have natural anonymity, and also exactly this anonymity, has pushed the hair of block chain technology
Exhibition.Block chain technology is needed based on its own technology realized, generally uses the Hash codes derived from by client public key as user
Participate in the address (account or ID) of block chain transaction.For public chain, this address is that user is given birth to specific tool software oneself
At, without anyone examination & approval, thus there is natural anonymity.There is bring anonymity issue in current year internet, further
Secondary kind appears in face of human society in the form of other one.If this anonymity problem of block chain, cannot rationally solve, not only
It is unfavorable for the development of block chain itself, serious problem but will be brought to the improvement of human society, is naturally repelling anonymity
Certain fields (such as alliance's chain), can not real application block chain technology.Therefore, the anonymity issue for solving block chain, not only anticipates
Justice is great, even more the developmental milestone of alliance's block chain technology.
Firstly, anonymity is not good for nothing, anonymity is also the natural needs of the mankind simultaneously.Based on early block chain skill
The encryption currency of art exactly meets the mankind for anonymous natural needs, obtains unprecedented development, also greatly pushed block
The development of chain technology.Based on this trend, some encryption currency, in anonymity, this road the more is walked the more remote, or even occurs as door sieve
This encryption money-system that ultimate attainment anonymity is pursued by anonymity signature technology (such as ring signatures algorithm) of coin (code name XMR).
The mankind also naturally need real name while naturally needing anonymity, in many fields (such as between legal person
Transaction), if not can determine that the identity of counterparty, transaction will be unable to carry out.Moreover, the order control based on human society needs
It wants, also only real name just can solve.It may be said that real name is the needs of society, anonymity is a human needs, but people can not be detached from
Society and exists, therefore anonymous only titbit, real name are only mainstream.
Block chain technology is developed so far, and anonymity technology development obtains rapid progress, instead in the technical development of real name, into
It opens up very slow.Currently the only to see, the alliance platform chain Fabric of only IBM introduces ca authentication mechanism, either node,
Or user, it is necessary to by block chain could be accessed after Fabric CA system certification, trade.Certain IBM is not only
One, on other alliance's platform chains, there are also the trials for introducing ca authentication.Alliance's platform chain comparative situation of mainstream is such as
Under:
1) the built-in CA system of Hyperledger Fabric, does not support third party CA at present；
2) FISCO BCOS supports third party's certificate, supports the revocation of certificate, supports more CA；
3) Coco, Quorum, Corda there are no such support.
In conclusion the CA system of IBM Hyperledger Fabric is most complete, but there are many limitations in scalability；
FISCO BCOS be towards domestic block platform chain, scalability be it is advantageous, especially towards domestic application when；
Coco, Quorum and Corda do not handle CA problem directly, and CA problem has been totally left to user, has been equivalently employed without solution real name
The scheme of problem.
The block chain world not yet, but can unify traditional third party's ca authentication there is an urgent need to mature and reliable at present
Technical solution.
In conclusion FISCO BCOS platform is theoretically best to the support of third party CA, but technology and apply maturity
Wait the inspection in market.Technology and application are most mature at present, most mainstream, and influence power is maximum or IBM Fabric, but
Fabric platform can not be docked with traditional third party CA.Therefore, in current mainstream alliance block platform chain, there has been no one
Kind is stablized, the technical solution of reliable and traditional third party's ca authentication perfection compatibility.If not solving this problem, the following alliance
The transaction of chain once generates dispute, and can the built-in ca authentication of Fabric platform have third party CA law complete like that and put to the proof energy
Power, at present in the judicial domain or blank in China.This will cause serious legal consequence.
