Description

Multi-center finite-area block chain authentication system with ownership currency issuing mechanism and block chain issuing mechanism
Technical Field
The invention relates to the technical field of block chains.
Background
With the continuous research and application promotion of bit currency and block chain technologies, decentralized block chain authentication, consensus mechanisms and intelligent contracts are more and more widely concerned, but mining mechanisms and workload certification mechanisms which are driven and promoted in the block chain technologies are difficult to introduce in wider alliance chain and private chain applications of non-bit currency master-right currency applications, and block chain block distribution mechanisms are difficult to adopt in alliance chain and private chain application scenarios of a large number of non-bit currency applications. Meanwhile, the traditional bitcoin block chain adopts a full-node verification recording mode of all participants, and is not an optimal scheme in many application scenarios.
In a large number of non-bity currency application scenarios, we need to borrow or reserve the block structure form of the block chain and the block chain account book and the block chain multi-node authentication mode, and need to remove the most basic mining mechanism and workload certification mechanism relying on survival and driving in the block chain architecture. Therefore, a brand-new block publishing mechanism must be constructed, a brand-new multi-center block chain mutual authentication system architecture based on a 'people-oriented-self, i.e. people' belt block publishing mechanism is constructed, and a server-level limited-domain-based mutual-assistance type block chain authentication of 'people-oriented-self, i.e. people' is used for replacing a traditional mining mechanism and a workload proving mechanism in a block chain of infinite-domain full-node authentication. In the finite field multi-center block chain authentication system architecture, when the number of centers of a plurality of centers is large enough, the authentication requirements issuing functions of the centers are different, but the authentication functions of the centers are similar on the finite field block chain authentication function, and the essence is still a decentralized or partially centralized authentication form. One of the typical applications of this certification system architecture will be the application of various financial transactions in various mastership currencies and various certification-type applications requiring certification of event certification issuing requirements, so we can refer to this mutual-aid multi-center finite-area blockchain certification system architecture with a block issuing mechanism based on "person-to-person, i.e., man-to-man" as identown (the amu funds in the state treasury). The application scenes of the non-bitcoin type are numerous and complicated, and the brand-new and more flexible block chain authentication system framework has wide application value.
Disclosure of Invention
The invention aims to solve the problems in the prior art and discloses a multi-center finite-area block chain authentication system with a master currency issuing mechanism and a block chain issuing mechanism.
The technical scheme adopted for realizing the purpose of the invention is that the multi-center finite area block chain authentication system with the ownership currency issuing mechanism and the block chain issuing mechanism is characterized in that:
the authentication system (identown) consists of a currency issuing authentication center and a plurality of financial authentication centers. Each financial authentication center needs to pass a protocol to join the authentication system (identown).
The currency-issuing certification authority generates digital currency. After the digital money is generated, the digital money is distributed to each financial authentication center and circulated.
When circulating, the digital currency is firstly matched to a corresponding account. The digital currency flows between accounts as transactions occur on each account.
Each financial authentication center at least comprises a basic database, an authentication information system and a block chain authentication and accounting system.
The base database stores account information and digital currency information. When a transaction occurs, authentication information is generated.
In a block record release period, the authentication information system broadcasts authentication information.
Each financial authentication center comprises a block chain authentication accounting system. The blockchain authentication accounting module records the broadcasted authentication information.
If a financial authentication center receives a block issue command, the center becomes a block issue node. And the block issuing node generates block data (identblock) with a timestamp according to authentication information generated in the authentication system within a period of time and broadcasts and issues the block data (identblock) to the whole authentication system.
The block data includes a block header (identhead) and a block body (identbody). The block area collects authentication information broadcasted in a period of time, and the authentication information is used as a calculation parameter and processed into root data. The root data is processed into authentication data as a calculation parameter. The authentication data is recorded in a block header area.
The published block data is received by other financial authentication centers in the authentication system. When a block data is verified and confirmed by the system, the block data is used as the latest block to be connected to the back of the previous block and stored in the block chain. The system enters the next block record distribution cycle.
Further, the digital currency is in the form of one certificate at a time. When every transaction happens, the corresponding financial authentication center can judge the authenticity of the digital currency through the currency issuing authentication center and update the digital certificate of the digital currency.
Further, the account is in the form of one certificate at a time. When every transaction happens, the corresponding financial authentication center can verify the authenticity of the account and update the digital certificate of the account.
Further, the money issuing authentication center is a central bank of one country. The financial authentication center is a commercial bank or a third party payment mechanism.
Further, the authentication information further includes: self-checking parameters, health values and engagement.
The health parameter values form the following rules:
a) if the data issued by one financial authentication center is not verified, the health parameter value of the financial authentication center is reduced.
And/or b) the financial authentication center performs self-checking on the data in the basic database. The result of the self-test affects the value of the health parameter.
And/or c) if a financial certification authority does not issue certification information during the block record issuing period, the health value may be reduced.
The participation degree value is formed according to the following rules:
a) if a financial authentication center participates in the distribution of block data, the participation degree value increases.
And/or b) if a financial authentication center refuses to participate in issuing block data, the participation degree value decreases.
Furthermore, if a certain financial authentication center receives the block issuing command, the certain financial authentication center becomes a block issuing node, and the financial authentication center which does not receive the block issuing command is a non-issuing node. Each time the block data is distributed, the distribution node is randomly designated.
Further, the authentication system sets an intelligent protocol rule. By this rule, all or part of the financial authentication center is randomly designated as the block issuing node.
Furthermore, the financial authentication center assigned to distribute the block data is a block distribution node, and the other financial authentication centers are non-block distribution nodes.
The block data issued by all the block issuing nodes is verified by the financial authentication center. All the financial authentication centers determine which block data is stored in the block chain as the latest formal valid block according to the set verification rule.
Further, the check rule is a majority rule.
Further, when the financial authentication center joins the authentication system (identown) through a protocol, it is necessary to check whether the financial authentication center is a server storing the verification information.
Further, when the financial authentication center joins the authentication system (identown) through a protocol, manual review is required.
Further, each financial authentication center includes a pool of authentication information records. If an authentication message is not recorded by a block of data. The authentication information is retained in the authentication information recording pool and is preferentially recorded in the next block before the next block data is generated.
Furthermore, the block chain is a multi-chain system and comprises a plurality of block chains meeting different functional requirements; the block comprises a block chain type code; the blockchain type code records item types; the item categories include trades, petty trades, stock trades, non-financial trades, and/or industry codes.
Further, the item category is a small transaction and corresponds to a small transaction block chain; the item type is transaction and corresponds to a transaction block chain; each small amount transaction record generated corresponding to the account information is recorded in a small amount transaction block chain; the balance count of the small transaction generated in each appointed time period corresponding to the account information is recorded in the transaction block chain.
Further, the item category is a small transaction and corresponds to a small transaction block chain; the small transaction chain may contract a life cycle beyond which historical data of the block chain will be automatically deleted.
The technical effects of the invention are undoubted:
1) the admission mechanism is set, so that the order of the financial industry is controllable, and the safety of transaction is ensured.
2) And the random majority principle is adopted, the reliability of the block chain authentication system is exerted, and the transaction is ensured to be real.
3) Abandons the 'mine digging mechanism' and 'workload' proving mechanism of the existing bitcoin system. A mechanism of "engagement", "health value" is introduced. So that the blockchain system is pushed to run healthily and continuously.
4) The "finite field blockchain", i.e. the number of financial authentication centers is limited and only the (servers of the) financial authentication centers participate in the blockchain authentication. The holder of the account (the bank's customer) can only access the financial authentication center and make requests for transactions and does not participate in blockchain authentication. The security of the system is posted.
5) The mode of one-time evidence is adopted, and the problem of 'double flowers' of the existing block chain is avoided.

Example 1:
a multi-center finite domain block chain authentication system with an ownership currency issuing mechanism and a block chain issuing mechanism is characterized in that:
the authentication system (identown) consists of a currency issuing authentication center (central bank server) and several financial authentication centers (commercial bank servers). When the financial authentication center joins an authentication system (identown) through a protocol, manual review is required.
The currency-issuing certification authority generates digital currency. After the digital money is generated, the digital money is distributed to each financial authentication center and circulated.
When circulating, the digital currency is firstly matched to a corresponding account. The digital currency flows between accounts as transactions occur on each account.
Each financial authentication center at least comprises a basic database, an authentication information system and a block chain authentication and accounting system.
The base database stores account information and digital currency information. When a transaction occurs, authentication information is generated.
In a block record release period, the authentication information system broadcasts authentication information.
Each financial authentication center comprises a block chain authentication accounting system. The blockchain authentication accounting module records the broadcasted authentication information.
The authentication system sets an intelligent protocol rule. By this rule, all or part of the financial authentication center is randomly designated as the block issuing node. If a certain financial authentication center receives the block issuing command, the certain financial authentication center becomes a block issuing node, and the financial authentication center which does not receive the block issuing command is a non-issuing node. Each time the block data is distributed, the distribution node is randomly designated. And the block issuing node generates block data (identblock) with a timestamp according to authentication information generated in the authentication system within a period of time and broadcasts and issues the block data (identblock) to the whole authentication system.
The block data includes a block header (identhead) and a block body (identbody). The block area collects authentication information broadcasted in a period of time, and the authentication information is used as a calculation parameter and processed into root data. The root data is processed into authentication data as a calculation parameter. The authentication data is recorded in a block header area.
The authentication information further includes: self-checking parameters, health values and engagement.
The health parameter values form the following rules:
a) if the data issued by one financial authentication center is not verified, the health parameter value of the financial authentication center is reduced.
b) And the financial authentication center performs self-inspection on the data in the basic database. The result of the self-test affects the value of the health parameter.
c) If a financial certification authority does not issue certification information during the block record issuing period, the health value may be reduced.
The participation degree value is formed according to the following rules:
a) if a financial authentication center participates in the distribution of block data, the participation degree value increases.
b) If a financial authentication center refuses to participate in the distribution block data, the participation degree value is reduced.
The published block data is received by other financial authentication centers in the authentication system. When a block data is verified (by checking rules) by the system, it is stored in the block chain as the latest block connected to the end of the previous block. The system enters the next block record distribution cycle. The check rule is a majority rule.
Each financial authentication center includes a pool of authentication information records. If an authentication message is not recorded by a block of data. The authentication information is retained in the authentication information recording pool and is preferentially recorded in the next block before the next block data is generated.
Example 2
This embodiment is mainly the same as embodiment 1, and further, the digital money is in the form of one certificate at a time, namely, CAi&MBi，jIn the form of (1). Stored in the central row server is the MA corresponding to the central row serveri&CBi，jForm (a).
Each time a transaction occurs, the corresponding financial recognitionThe certificate center can judge the authenticity of the digital currency through the currency issuing certification center and update the digital certificate CA of the digital currencyiAnd CBi，j. The updated certificate is broadcast as authentication information, participating in the calculation of the blockchain.
Example 3
This embodiment is mainly the same as embodiment 1, and further, the account is in the form of one certificate at a time. I.e. a CD in a carrier for an account such as a bank cardq&MEq，pIn the form of (1). Stored in the business server is the corresponding MDq&CEq，pForm (a).
Each time a transaction with a reduced amount of digital money (e.g., withdrawal, remittance to another person, etc., a transaction without an increase in data money, e.g., deposit, receipt of remittance, etc.) occurs, the corresponding financial certificate authority determines whether the account is authentic or counterfeit by the money issuing certificate authority and updates the digital certificates CDq and CEq, p of the account. The updated certificate is broadcast as authentication information, participating in the calculation of the blockchain.
Example 4:
the financial transaction chain comprises a small amount transaction chain, a transaction chain and other multi-chains. Each small amount transaction record generated corresponding to the account information is recorded in a small amount transaction block chain; the balance count of the small transaction generated in each appointed time period corresponding to the account information is recorded in the transaction block chain. One can set the transaction behavior of 100 yuan initiated by the account of the non-financial institution as a small amount transaction and record it in different ways into a small amount transaction chain and a transaction chain respectively. Such as:
transaction account A
During 2017, 10 months, 150 micropayments take place in total, and each micropayment which occurs is recorded in a micropayment chain; at the end time of the monthly accounting period, the accumulated counts of the 150 small transactions are paid out for 578.99 yuan after the item overlapping, and then 150 small transactions occur in the transaction account A recorded in the transaction chain at the end time of the accounting period, and the net expenditure of the item overlapping is 578.99 yuan;
during 2017 and 10 months, 3 normal transactions take place in total, and then 3 transactions are recorded in a transaction chain;
the recording condition of the account A in the blockchain authentication system in 2017 and 10 months is as follows:
a petty payment chain, 150 postscript bookings;
the transaction chain, 3 normal transaction bibliographies +1 cumulative payout of 150 micropayments 578.99 yuan.
Example 5:
the daily small-amount transaction quantity is huge, particularly with the development of mobile payment, the small-amount transaction is huge mass data, but the transaction storage value is not large, and the small-amount transaction is specially recorded in a small-amount transaction chain and separated out to be a very good option. In this regard, the present embodiment sets the transaction behavior of 100 yuan initiated by the non-financial institution account as a small transaction and records it into a small transaction chain. Because daily small transaction data is extremely large and complex, the life cycle of the small transaction chain is set to be 1 year in the embodiment. When the year expires, the small transaction chain of the present embodiment is annihilated.
