Description

The architectural framework of the shared open data of transregional piece of chain under a kind of isomery multichain framework

Technical field

The present invention relates to block chain technical field, more particularly to isomery block chain interconnection technique is based on, realize data across The secure and trusted opening and shares of mechanism.

Background technique

Data silo is the loss of the whole society.For example, you have money on deposit in industrial and commercial bank, buy house in safety bank loan, In company of CITIC Securities transaction's stock, while there are also the credits card of China Merchants Bank.Individual be data of financial transaction the producer and Owner, and this 4 financial institutions are the custodians of data.But due to different financial institutions, cause the data of same individual It isolates.Since data have important commercial value for mechanism, they are actively to open to the outside world easily.

Such as financial industry, finance data do not open, and some influences are all brought on each side.For individual, most directly Loss be that can not compare service and expense easily, so that cheap and good-quality financial product can not be selected.Bigger loss is, Individual is unable to get comprehensive finance data, therefore limits efficient portfolio configuration and planning.Big data analysis and artificial intelligence The advanced technology such as Investment & Financing is supported due to lacking complete and comprehensive data, becomes ornaments.For financial technology company, Non-financial data are obtained in spite of many modes, but the gold content of these data, less than the personal finance transaction in bank Data.If can not break bank data barrier, financial technology company will be in a disadvantageous position always, and development is necessarily restricted. For bank, data are underground, are a kind of temporary protections to own service.But this closed cost of data is bank The innovative technology to lose opportunity using shared data and financial technology company, so that being difficult to client provides more polynary product And service.Higher and higher, scientific and technological circle giant is required transboundary to compete more and more fierce, social and supervision pair financial service in client Under the more more and more intense spring tide of the cry of open data, self-contained bank constructs the chance of the platform ecosphere by losing, silver Capable road the more will be walked the more narrow.

Data, which are isolated, is not only limited to financial industry, and in medical information field, there is also data silo, now, more than 90% Hospital use electronic health record way to manage, but these electronic medical record systems only by case history electronization, electricity used at present The basic functions such as sub- medical records system only has case history storage, index is searched.These functions are only to accelerate the typing speed of case history Degree, reduces the hand labour and the duplication of labour of doctor.The function of electronic health record is not given full play to.It is continued to develop in informationization While, electronic medical record system will be changed into centered on patient, possess the verification machine of electronic health record authenticity and integrity System provides data medical shared channel, it is total to can be realized hospital, pharmacy, patient, insurance institution and scientific research institution's data It enjoys, to realize that medicine separation provides basis, provides data for medical science career development and support, take care of data, protection for patient Privacy is brought convenience.

Current the block catenary system of mainstream and block chain project on the market, are to belong to a kind of independent block catenary system, The channel of data exchange and approach, current this epidemic situation comparison are not similar to during internet development between each other, enterprise Also in the epoch for establishing internal lan.With the development and differentiation of block chain technology, it necessarily will appear enterprise and enterprise The demand of data exchange is carried out between block catenary system.

Nowadays, the level of informatization is deepened, and various industries continue to develop, perfect, but Information Security, sharing, privacy Property the significant challenge that still suffers from, also exactly it is considered that block chain can put forth effort place.However, safe and reliable in order to realize Open data, there are the following problems：

1, across organization data reachability problem, data interaction speed issue；

2, the data quality problem of source data, data integrity, authenticity are unable to get guarantee；

3, user data privacy problem；Private data leakage, abuse.

The privacy that can be good at protecting data using block chain technology, provides the verifying of data integrity and authenticity Mechanism, but block chain the problems such as facing poor storage performance, dimension-limited and not seeking unity of standard at present.

In current research, a variety of independent blocks chains become parallel to be expanded block chain scale and breaks through function restriction most The way of mainstream, the present invention will construct in the parallel structure of the block chain based on a variety of independences and isomery, realize intelligent data Circulation duct, general frame is as shown in Fig. 2, a kind of seamless and controllable mode of data flow between permission system circulates.

Preferably, the data analysis module includes that data analysis is calculated with module, distributed computing module, memory is excavated Module and streaming computing module.

Preferably, the multichain agreement is based on block chain interconnection model (Inter-BlockChainModel, IBCM), In across chain transaction transmission be packaged, parse and forwarded by block chain router, the block catenary system being linked into network only needs It realizes interface provided by routing, converts standard transaction for different types of transaction, it can connection isomorphism and isomery Block catenary system, across chain transaction transmission are transmitted using point-to-point mode, without going past the equipment that any third party provides, To guarantee the privacy of transmission, the block chain router is a block catenary system, can prevent from practising fraud, while each section Point can be extended to a cluster and externally provide service；It runs succeeded including across chain transaction, across chain transaction executes failure, across chain friendship Three kinds of situations of easy Retransmission timeout.

Preferably, across the chain transaction implementation procedure that across the chain transaction runs succeeded is as follows：

Assuming that the address A2 into block catenary system S2 of the address A1 in block catenary system S1 has initiated across a chain transaction,

(1) block catenary system S1 is receiving across chain transaction T ' later, into the pre-preparation stage, locks underlying assets, will Temporary address A of the assets transfer to routing R1_t1In, then there is TRANSFER (A₁,A_t1, value) and value Transfer function representation is by ground Location A₁Middle quantity is the assets transfer of value to address A_t1In, transaction T ' is then sent to routing R1 connected to it；

(2) routing R1 receives transaction T ' later, will locally across chain transaction be packaged using function PACKAGE, and finally will beat The transaction wrapped is sent to routing R2, is transmitted to block catenary system S2 by routing R2, the function PACKAGE is to be packaged function；

(3) the routing R2 being connected with block catenary system S2 is receiving across chain transaction T ' later, uses function UNPACKAGE will trade T ' unpack for defined in local block catenary system S2 trade T ", and will transaction T " be sent to block chain System S2；

(4) block catenary system S2 receives the transaction T " forwarded by routing R2 and transaction T " later, is put into local friendship Easily in caching, after passing through by internal consensus, it will confirm that transaction is sent to and area into pre- presentation stage, and via routing R2 The routing R1 of block catenary system S1 connection；

(5) after routing R1 receives confirmation transaction, it will confirm that information is transmitted to block catenary system S1, and be put into its transaction In caching, the internal consensus of block catenary system S1 is waited for, at this point, block catenary system is by that can incite somebody to action after internal consensus Transaction is submitted completely, by assets from A_t1It is transferred to the temporary address A of routing R2_t2In, then there is TRANSFER (At₁,At2,value) Value Transfer function representation is by address At₁Middle quantity is the assets transfer of value to address A_t2In, and confirmation transaction is sent to road By R1, block catenary system S2 is sent to by routing R1；

(6) after block catenary system S2 is received by routing the confirmation transaction that R2 is forwarded, transaction can be submitted completely, By assets from A_t2It is transferred to address A₂In, then there is TRANSFER (A_t2,A₂, value) and value Transfer function representation is by address At₂In Quantity is the assets transfer of value to address A₂In, and store into block catenary system, across chain transaction is finished.

Preferably, across the chain transaction implementation procedure that across the chain transaction executes failure is to set to work as first to have block catenary system User, if executing failure in block catenary system S1, is not necessarily into block catenary system S2 when across the chain transaction of user's initiation in S1 Carry out across chain transmission, it is only necessary to the feeding back unsuccessful in local block catenary system S1；If can be held in block catenary system S1 It goes successfully, then with regard to needing to carry out across chain transmission, is communicated with block catenary system S2.Failure is executed in block catenary system S2 Across chain transaction implementation procedure includes：

(1) block catenary system S1 is receiving across chain transaction T ' later, can enter the pre-preparation stage, lock underlying assets, By assets transfer to the temporary address A of routing R1_t1In, then there is TRANSFER (A₁,A_t1, value) and value Transfer function representation general Address A₁Middle quantity is the assets transfer of value to address A_t1In, transaction T ' is then sent to routing R1 connected to it；

(2) routing R1 receive transaction T ' later, using function PACKAGE will locally across chain transaction T ' packing, finally general Packed transaction is sent to routing R2, is transmitted to block catenary system S2 by routing R2, the function PACKAGE is to be packaged letter Number；

(3) the routing R2 being connected with block catenary system S2 uses function after receiving across chain transaction T UNPACKAGE will trade T unpacking as transaction T " defined in local block catenary system S2, and the T " that will trade is sent to block linkwork Unite S2；

(4) block catenary system S2 receives the transaction T " forwarded by routing R2 and transaction T " later, is put into local friendship Easily in caching, during carrying out internal consensus, transaction T " is verified or is executed failure, then refuses this transaction, will refuse information Block catenary system S1 is transmitted to by routing R2；

(5) block catenary system S1 is received via the assets that after the refusal information for routing R1 forwarding, will can be locked before It unlocks and by assets from address A_t1In be transferred to address A₁In, then there is TRANSFER (A_t1,A₁, value) and value Transfer function table Show address A_t1Middle quantity is the assets transfer of value to address A₁In, transaction is finished.

Preferably, across chain transaction Retransmission timeout indicates in the implementation procedure traded across chain, since across chain transmission belongs to a little To a transmission, it may occur that transaction sends the case where losing, the address into block catenary system S2 the address A1 in block catenary system S1 A2 has initiated across a chain transaction, and after confirmation transaction is lost, across the chain transaction implementation procedure that time-out is retransmitted includes：

(1) block catenary system S1 is receiving across chain transaction T ' later, can enter the pre-preparation stage, lock underlying assets, By assets transfer to the temporary address A of routing R1_t1In, then there is TRANSFER (A₁, At1, value) and value Transfer function representation general Address A₁Middle quantity is the assets transfer of value to address A_t1In, transaction T ' is then sent to routing R1 connected to it；

(3) the routing R2 being connected with block catenary system S2 uses function after receiving across chain transaction T It is transaction T " defined in local block catenary system S2 that UNPACKAGE, which unpacks transaction,, and the T " that will trade, it is sent to block chain System S2, the function UNPACKAGE are to unpack function；

(4) block catenary system S2 receives the transaction T " forwarded by routing R2, later, by the T " that trades, is put into local Transaction caching in, after passing through by internal consensus, into pre- presentation stage, and via routing R2 will confirm that transaction be sent to The routing R1 of block catenary system S1 connection；

(5) it is traded by the confirmation of routing R2 forwarding due to network failure, fails to be transmitted to routing R1.It routes R1 and is waiting one The section time does not still receive after the message of routing R2, it will sends transaction T again and gives routing R2；

(6) after routing R2 receives transaction T, analysis finds that this transaction is received and has verified that and executed, this When can send again confirmation transaction to routing R1；

(7) after routing R1 receives confirmation transaction, it will confirm that information is transmitted to block catenary system S1, and be put into its transaction In caching, the internal consensus of block catenary system S1 is waited for, block catenary system passes through after internal consensus, can will trade It is complete to submit, by assets from A_t1It is transferred to the temporary address A of routing R2_t2, in, then there is TRANSFER (At₁,A_t2, value) and value Transfer function is indicated address At₁Middle quantity is the assets transfer of value to address A_t2In, and confirmation transaction is sent to routing R1 is sent to block catenary system S2 by routing R1；

(8) after block catenary system S2 is received by routing the confirmation transaction that R2 is forwarded, transaction can be submitted completely, By assets from A_t2It is transferred to address A₂In, then there is TRANSFER (A_t2,A₂, value) and value Transfer function representation is by address At₂In Quantity is the assets transfer of value to address A₂In, and store into block catenary system, across chain transaction is finished.

Specific embodiment

Current the block catenary system of mainstream and block chain project on the market, are to belong to a kind of independent block catenary system, The channel of data exchange and approach, the present embodiment have not broken the technology of this independent blocks chain no data exchange between each other Obstacle proposes a kind of architectural framework of the shared open data of transregional piece of chain under isomery multichain framework, referring to Fig. 1, the architectural framework Including：

(1) application layer：Including OpenData module, intelligent contract module (including：Contract template, contract audit, contract are empty Quasi- machine and contract language), more account book enquiry modules (including：Correlation inquiry sorts out inquiry, Fusion query and sorting query) sum number According to analysis module (including data analysis and excavation module, distributed computing module, memory computing module and streaming computing module)；

OpenData module is based on the OpenData model under isomery multichain framework, data open model data referring to fig. 2 Circulate schematic diagram.The model includes four submodules：(1) agree to authorization submodule, propose data requirements, user for third party Third party's permission is given, it is allowed to obtain access user data；(2) authentication sub module, for data storing side to user identity into Row certification；(3) submodule is authorized, confirms that keeping side will corresponding request of the third party to data acquisition for user；(4) cancel Authorize submodule；The OpenData realizes that function includes：Quickly enter an item of expenditure in the accounts, amount, fund, loan, information implement it is shared and Use innovative technology service safely.Deeper function may be implemented in the extension of the model, including：

● supervision (governance)：Provide a non-stop layer, completely self-contained supervision Data Share System；Allow ginseng It fulfils obligations with person and right.

● security strategy：User can be allowed to understand letter of consent (consent) content, and guaranteed data security.User is private Personal data has to pass through my authorization and agrees to.

● data standard：Existing data standard, data set, data structure can be made full use of.Or establish a number According to model.Establishing a data standard can simplify Global finance data exchange (ISO 20022financial industry message scheme)；Use Json, HTTP, Restful.

Interconnection protocol is mainly designed in terms of these from safety, privacy and operating efficiency, and across chain agreement is main Solve the problems, such as the consistency of data in data exchange process between multichain, including basic constructional design and block chain interconnection model Design two main parts.

(1) basic constructional design：Expandable system structure based on interconnection chain is designed using layered componentization, and each layer can The extension of block chain is realized with the plug by component.For the extension of an individual block catenary system, block link layer It is expansible be it is most important, clarifying the meaning of following technical characteristic and the effect in basic constructional design facilitates this field skill Art personnel understand the solution of the present invention.

(1) it trades and signs

In block catenary system, all information is all transmitted and is converted in the form of " transaction " (Transaction), Therefore, transaction is the part of opposite core in entire block catenary system.Transaction is a string of computer instructions by encryption, is used Corresponding rule operation data, to guarantee the normal operation of block catenary system.In order to be compatible with the block linkwork of isomorphism and isomery System, needs to define the transaction format of standard, to realize interconnecting for data between different blocks catenary system.The present invention determines The transaction of justice had both included to be sent to block chain comprising top layer's application layer service logic similar to true money transfer transactions, while also The data for needing to store in system.In block catenary system, each block can store transaction list, the present invention use symbol It indicates transaction List Table (TransactionList), indicates a transaction with symbol T.Format trade as indicated at 3, the transaction of standard Three kinds of type of transaction are defined, are distinguished by type field, including three kinds of domestic transaction, across chain transaction and confirmation transaction.

A kind of network of the block chain as value delivery uses address (Address) during carrying out value delivery Information determines the affiliated of value, i.e. values of definite magnitude is stored in an address, if generating value delivery, can generate valence Value is transferred to the process of another address from an address.In the transaction of block catenary system, indicate to trade using address Promoter and recipient, address is indicated with lowercase a.One user can have multiple addresses, such as a₁, a₂..., a_n∈ u_i, indicate user u_iPossess a₁, a₂..., a_n.In view of Privacy Protection, address constant is designed as to the Kazakhstan of a string of 20 bytes Uncommon value, i.e.,WhereinRefer to character string,It is meant that the character string of 20 bytes.

In order to adapt to a variety of different type of transaction, three kinds of type of transaction defined in the present invention：Domestic transaction, across chain Transaction, confirmation transaction are all comprising following several fields：

(a) source address (from)：The address constant of the promoter of one expression value or data, is 20 bytes Address, for the transaction of general transaction or the intelligent contract of creation, this field is sky, can be used hereinCarry out table Show.This field uses character T_fIt indicates, therefore,Or

(b) destination address (to)：The address constant of the recipient of one expression value or data, is 20 bytes Address, for general transaction or the transaction created by using intelligent contract, this field is sky, can be used hereinTo indicate.This field uses character T_tIt indicates, therefore,Or

(c) timestamp (timestamp)：The timestamp that transaction is initiated, is indicated, this word with 64 binary system positive integers Section character T_sIt indicates,WhereinIndicate a Positive Integer Set,Then indicate the set of n binary system positive integers, I.e. number all in set is respectively less than 2ⁿ。

(d) serial number (number)：The corresponding serial number of exchange, as shown in figure 4, with one 128 binary system positive integers It indicates, this field uses symbol T_nIt indicates, therefore,Wherein, first 64 timestamps for indicating that transaction is sent, in Between 32 indicate that the block catenary system ID that transaction is initiated, last 32 expressions this time are stabbed under, the number under this block chain ID, from 0 starts counting.

(e) acknowledged sequence number (ackNumber)：It is only used for confirmation transaction, remaining type of transaction is sky, for certain serial number Transaction is confirmed.It is indicated with 128 binary system positive integers, this field uses symbol T_aIt indicates, therefore,Or

(f) type (type)：Type constant belonging to transaction, is indicated, this field with one 8 binary system positive integers Use character T_pIt indicates, therefore,

(g) Transaction Information (data)：For the related data of store transaction, set according to different blocks catenary system feature Meter, without fixed size, and there is no limit for size.This field symbol T_dTo indicate.

(h) signing messages (v, r, w)：For the relevant information of trading signature, variable v, r, w use T respectively_v, T_r, T_wCarry out table Show.

Therefore, a transaction T can be expressed as：

T≡(T_f, T_t, T_s, T_n, T_a, T_p, T_d, T_v, T_r, T_w) (1.1)

And

However judge a transaction whether effectively necessary not only for meeting above-mentioned condition, it is also necessary to meet trading signature just True property.It is similar to electronic signature to trading signature, the present invention signs to transaction using curve encryption algorithm.It assumes first that every A transaction sender has legal private key, uses p_rTo indicate.Private key is one 256 binary system positive integers, uses 32 Byte saves, and hasDefined function is signed (ECDSASIGN), is generated public key (ECDSAPUBKEY), and verifying It signs (ECDSARECOVER), these function performances are as follows：

Wherein p_uIt is the corresponding public key of private key, is indicated using the positive integer of 64 bytes, and public key is by two 32 words Section positive integer is spliced.V indicates decryption number, is indicated using a byte positive integer, and specify the symbol of curve point And finiteness.Judge that a signature is effectively, to need to meet following condition：

0 < r < secp256k1n ∧ (2.4)

0 < w < secp256k1n ∧ (2.5)

v∈{27.28) (2.6)

Wherein：

For given private key p_r, according to defined above, the address A (p of 20 bytes_r) i.e. 160, it is defined as Keccak- 256 hash algorithms take 160 of the most right side after Hash to ECDSA public key, as follows：

When signing to transaction, transaction is converted to using Keccak-256 Hash Encryption Algorithm the number of certain length According on the one hand the data of different length being converted to the data of equal length, in addition a side by the use of hash algorithm Face can judge whether data are tampered, if data have missing or are tampered, cryptographic Hash will be different.The application It is the data of 32 bytes by data encryption using Keccak-256 hash algorithm, Hash encryption function indicates with KEC.To friendship When easily carrying out Hash, T_v, T_r, T_wIt is not included in calculating, the Hash of transaction is expressed as h (T), is calculated by Keccak hash algorithm It is as follows later：

Transaction G (T, p after signature_r) got by calculating as follows：

And if only if

(T_v, T_r, T_w)=ECDSASIGN (h (T), p_r) (3.4)

It is S that definition transaction, which sends function, and the process for sending transaction T is as follows：

Therefore, according to above-mentioned derivation, judge whether a trading signature is effective, it is only necessary to which judgement sends function by transaction Whether calculating is identical as the address of sender later, that is, has：

(2) Merkle tree

On the one hand the list that transaction is stored in block needs to guarantee to hand over when executing encrypted communication to other nodes Transaction included in easy list will not be tampered or increase or reduce, and on the other hand also need to guarantee that transaction is being transmitted across It will not malfunction in journey.Traditional method is will to trade to be encrypted, and is then transmitted, and is decrypted at receiving node.So And since encrypted communication is frequent, trading volume is larger, and the management of frequent encryption and decryption and key is all relative complex, therefore cannot use Conventional approach, and the transaction List Table correctness for the use of not only solving the problems, such as transmission of Merkle tree, but also reduce transmission ring Section, to accelerate bulk velocity.Merkle tree itself is a binary tree, is developed from HashList, as shown in Figure 5. The leaf node of Merkle tree is data block, is herein each transaction, the bottom-up layer-by-layer Hash of progress, final To the root of Merkle tree.It is subsidiary to transmit Merkle tree together during being transmitted by the foundation of Merkle tree, In recipient, it is only necessary to one layer of data on each leaf node.If distorting, the root of Merkle tree will change Become, and the Transaction Information distorted can be found by binary chop.

Define Merkle tree is indicated with symbol M, and each layer is encrypted using Keccak-256 hash algorithm, then in Fig. 5 It is shown to be expressed as：

If number of transaction be odd number, the last one transaction without combination, directly use Keccak-256 hash algorithm into Row encryption, defines M^tFor t layers of all node sets of Merkle tree,For t layers of i-th of node of Merkle tree, The calculating function of Merkle tree is that Mk then has：

Wherein

(3) block chain structure

Block chain is the data account book that block is lined up according to timestamp one by one, therefore block is block catenary system The minimum unit of middle storing data, the not only independent interdependence again of each block pass through block Hash progress phase end to end between block Even, a chain is ultimately formed.Block stores data all in system, and including but not limited to previous block Hash, block are breathed out Uncommon, block height, timestamp, state root (global state), Merkle root, version number can be carried out according to different application scenarios Corresponding field increases.Of the present invention piece of chain structure is as shown in Figure 6.

As shown in fig. 6, the structure of block is broadly divided into two major parts, one is block head H, and one is block body T, B is used respectively_HAnd B_rTo indicate.It is joined end to end between block and block by block Hash, to form a chain, uses characterTable Show block chain, the i.e. set of block.

Wherein block head includes following information：

(a) previous block Hash (preHash)：The cryptographic Hash for referring to previous block head, is breathed out by Keccak-256 Cryptographic Hash after uncommon algorithm for encryption, size is 32 bytes, with symbol H_pIt indicates, and has

Block chain is given in expandable system structure based on interconnection chain in internal extended method and mode, and is had There is multichain, the extended method inside block chain can solve the extension in terms of business, however only be extended still in inside It is impossible to meet the development of current block chain technology.Multichain framework is given on the basis of the expansible architectural framework of block chain A kind of model for being adapted to interconnect between different blocks chain out is guaranteeing that each block chain can be with the base of isolated operation On plinth, the data between each block chain are shared, intercommunication, to realize the value delivery network of transregional piece of chain, is filled Divide and utilizes the resource in each block chain.As shown in fig. 7, constructing multichain agreement is based on block chain interconnection model (Inter- BlockChainModel, IBCM), block chain interconnection model considers reality in the design, the block being linked into network Catenary system will appear the case where isomorphism or isomery, and transaction format is different, in order to solve these problems, the mutual gang mould of block chain Type introduces the concept of routing, is used for transmitted transaction.In model, if any one block catenary system is wanted to be added in network, need It to be accessed together with a routing.By the connection of routing, a big network is ultimately formed.Routing and routing in network Between, using the organizational form of similar block chain, routing is existed simultaneously in a manner of node, and all routings form a block again Catenary system, for saving and safeguarding the routing iinformation of each block catenary system in network.Due to block chain have can not tamper And high fault tolerance, therefore saving routing iinformation using block chain is that comparison is safe.Meanwhile it is newly-increased carrying out routing iinformation When, it is also desirable to it as traditional block catenary system, knows together, is finally reached consistent to the increase of information.And the update of information, Due to the particularity of block catenary system, also handled in such a way that information is newly-increased, when reading routing iinformation, it is only necessary to obtain Take 32 maximum routing iinformations before priority.Over time, the block catenary system being added in network is more next More, the node routed in block chain can increase therewith, will necessarily reduce the speed of routing iinformation common recognition, however, due to routing Block chain only maintains routing iinformation, does not have excessive information processing, therefore, can't there is too big shadow to whole network It rings.Meanwhile the information routed on block chain is relatively stable, will not frequently generate the change of routing iinformation, it equally will not be to common recognition And network has much impact.After routing block chain data common recognition finishes, the routing that each block catenary system is connected is just Possess " address " of all block catenary systems, therefore, when there is across chain transaction, point pair can be passed through between block catenary system The communication modes of point carry out the exchange of data, any third party device or third party's tissue are needed not move through, to ensure that industry Privacy between business contact.Across chain transaction transmission is packaged, parses and is forwarded by block chain router, is linked into network Block catenary system only needs to realize interface provided by routing, converts standard transaction for different types of transaction, it can even Connect the block catenary system of isomorphism and isomery, across chain transaction transmission is transmitted using point-to-point mode, without going past any the The equipment that tripartite provides, to guarantee the privacy of transmission, the block chain router is a block catenary system, can be prevented Cheating, while each node can be extended to a cluster and externally provide service.

In IBCM, essential core thought is in order to which the outside for realizing block catenary system is expansible, it can connection is different Block catenary system, to meet the value delivery between different blocks catenary system.Carrying out the value delivery between transregional piece of chain In the process, it needs to standardize and constrain using across chain agreement, guarantees the security reliability of value delivery.Between transregional piece of catenary system Transaction during execution, due to being related to multiple block catenary systems, distributed problem can also be attributed to, benefit With solve distributed problem thought, with the value between address A2 in address A1 in block catenary system S1 and block catenary system S2 Based on transmitting, the process that across chain transaction executes is given, is run succeeded including across chain transaction, across chain transaction executes mistake It loses, three kinds of situations of across chain transaction Retransmission timeout.Value Transfer function TRANSFER is defined, then is had as follows：TRANSFER(A₁, A₂, Value) indicate by quantity in the A1 of address be value assets transfer into address A2.It is wherein isomery block shown in Fig. 8-10 Across the chain data communication of chain and trade agreement are with the valence between address A2 in address A1 in block catenary system S1 and block catenary system S2 Based on value transmitting, the process that across the chain transaction provided executes runs succeeded, across chain transaction executes mistake including across chain transaction It loses, three kinds of situations of across chain transaction Retransmission timeout, is illustrated respectively.

(1) across chain transaction, which runs succeeded, belongs to normal condition, excludes extreme case, and most of transaction can all run succeeded, To the transmitting of realized value.Such as Fig. 8 shows the address A in block catenary system S1₁The address A into block catenary system S2₂It initiates Across the chain transaction implementation procedure that across chain transaction described in one across chain transaction runs succeeded is as follows：

(1) block catenary system S1, into the pre-preparation stage, locks underlying assets after receiving across chain transaction T ', will Temporary address A of the assets transfer to routing R1_t1In, then there is TRANSFER (A₁,A_t1, value) and function, then transaction T ' is sent To routing R1 connected to it；

(2) after routing R1 receives transaction T ', it will locally across chain transaction be packaged using function PACKAGE, finally will beat The transaction wrapped is sent to routing R2, is transmitted to block catenary system S2 by routing R2, the function PACKAGE is to be packaged function；

(3) the routing R2 being connected with block catenary system S2 uses function after receiving across chain transaction T ' UNPACKAGE will trade T ' unpack for defined in local block catenary system S2 trade T ", and will transaction T " be sent to block chain System S2；

(5) after routing R1 receives confirmation transaction, it will confirm that information is transmitted to block catenary system S1, and be put into its transaction In caching, the internal consensus of block catenary system S1 is waited for, at this point, block catenary system is by that can incite somebody to action after internal consensus Transaction is submitted completely, by assets from A_t1It is transferred to the temporary address A of routing R2_t2In, then there is TRANSFER (At₁,A_t2, Value), and confirmation transaction is sent to R1 is routed, be sent to block catenary system S2 by routing R1；

(6) after block catenary system S2 is received by routing the confirmation transaction that R2 is forwarded, transaction can be submitted completely, By assets from A_t2It is transferred to address A₂In, then there is TRANSFER (A_t2,A₂, value), and store into block catenary system, across chain Transaction is finished.

(2) across chain transaction executes failure：Across chain transaction has identical place with domestic transaction to a certain extent, equally The case where having execution failure, when there is user's across chain transaction of user's initiation into block catenary system S2 in block catenary system S1, If executing failure in block catenary system S1, without carrying out across chain transmission, it is only necessary to be fed back in local block catenary system S1 Failure；If can run succeeded in block catenary system S1, with regard to needing to carry out across chain transmission, with block catenary system S2 into Row communication.It is as shown in Figure 9 that failure is executed in block catenary system S2.Implementation procedure includes：

(1) block catenary system S1 is receiving across chain transaction T ' later, can enter the pre-preparation stage, lock underlying assets, By assets transfer to the temporary address A of routing R1_t1In, then there is TRANSFER (A₁,A_t1, value) and function, then will trade T ' hair Give routing R1 connected to it；

(5) block catenary system S1 is received via the assets that after the refusal information for routing R1 forwarding, will can be locked before It unlocks and by assets from address A_t1In be transferred to address A₁In, then there is TRANSFER (A_t1,A₁, value) and function, it trades and has executed Finish.

(3) across chain transaction Retransmission timeout indicates in the implementation procedure traded across chain, due to across chain transmission belong to it is point-to-point Transmission, it may occur that transaction sends the case where losing, and referring to Figure 10, the address A1 in block catenary system S1 is into block catenary system S2 Address A2 has initiated across a chain transaction, after confirmation transaction is lost, overtime across the chain transaction implementation procedure packet retransmitted It includes：

(7) after routing R1 receives confirmation transaction, it will confirm that information is transmitted to block catenary system S1, and be put into its transaction In caching, the internal consensus of block catenary system S1 is waited for, block catenary system passes through after internal consensus, can will trade It is complete to submit, by assets from A_t1It is transferred to the temporary address At2 of routing R2, in, then there is TRANSFER (At₁,A_t2, value) and function, And send confirmation transaction and give routing R1, block catenary system S2 is sent to by routing R1；

(8) after block catenary system S2 is received by routing the confirmation transaction that R2 is forwarded, transaction can be submitted completely, By assets from A_t2It is transferred to address A₂In, then there is TRANSFER (A_t2,A₂, value), and store into block catenary system, across chain Transaction is finished.

The framework includes identity validation module.In current block chain technology, there are a variety of in a block catenary system The node of type, in true application scenarios, there is also a large amount of roles, different roles has different rights.In multiple areas It is one by the superposition that multiple simple identity authenticates there is also authentication mechanism, process are different in block catenary system interconnected model The simple solution of kind, but there are many problems, greatly reduce the flexibility of authentication.Identity validation is multichain system Important component part in system limits different user and node to the access limit of data by authentication.Pass through identity Affirmation mechanism, can determine deal required Permission Levels when block chain network is established, and can determine when network is established Adopted block chain network is open, to reduce access difficulty and support quickly and efficiently to promote, or is that high controllable environment defines More limitations.Mark management service is provided and is provided by the confirmation to different identity, the participant in multichain system is identified The management of the reading and authorization that are combined with role.Multipart identification authentication and administrative mechanism needs are further perfect, to meet More fine-grained rights management and more complicated, more flexible business demand.Include for more specifically：

(1) research of multipart identification authentication, in OpenData model, there are data storage side, data user and use Family, different role should correspond to different permission and function.Meanwhile reliable authentication can effectively realize identity pipe Reason.

(2) across chain user data ownership, in independent block catenary system, user data ownership can by public and private key To manage data ownership well, data abuse is prevented；In multichain framework, guarantees that data are related to repeatedly authenticating across chain, mention High authentication efficiency and authentication reliability are extremely important.

(3) supervision across chain data, for user data, user possesses the ownership of data, for data flow, is made With situation, should user possess right to know, across chain data are supervised, are to realize open data essential step.

The present invention is made to solve using multifactor identity identifying technology and participates in multi-level certifying key system in many ways, this It is current perfectly safe, the highest authorization method of safety.Authorization is to verify the process of user subject identity.Dual factor anthentication skill Art can be made of multiple simple authentication processes, to guarantee safe identity validation, and be eliminated during single simple authentication Key or token leakage.But in this method, simple be added multiple simple authentication process is not one good more Factor authentication method greatly reduces the flexibility of ciphering process in this way.

The present invention uses the dual factor anthentication technology realized based on Threshold cryptosystem method, more flexible, efficient and conveniently.Thresholding The core concept of enciphered method is that information is protected by multiple stage computers collaborative process fault-tolerant calculation, most critical in Threshold cryptosystem How safely problem is shared key, and a key sharing model allows key distributed storage on multiple servers, And meet following require：Number of servers will more than thresholding numerical value well；When needing key recombination ground, ground clothes are participated in Device quantity of being engaged in will be more than threshold value.It is based on this realization process of the invention：It is close that key is divided into multiple sons by Threshold cryptosystem method Key when group number of keys reaches threshold value, can just recombinate key.More specifically, the mode of Threshold cryptosystem method can be expressed as (t, n), what n was represented is the quantity of sub-key after key is decomposed, and t is the threshold value using defined, when the sub-key number possessed When amount reaches t, the recombination of complete pairwise key.

The present embodiment is established for based on the OpenData model under isomery multichain framework, solves a plurality of isomery block The problem that interconnects between chain, multichain system interior joint Verify Your Identity questions, when across chain data interaction, the traceability of data Problem and user data privacy problem prevent private data leakage, abuse, shared OpenData data that data safety is credible Secure and trusted shared architectural framework defines the generation of data, shared and access mechanism, and the data storage based on block chain changes The drawback centrally stored into data under the frame of OpenData, helps the shared data of user security, enjoys with allowing user security It is serviced by provided by third party, also high quality, complete, reliable data is provided for research institution, with practicable pass Key technology solves the problems, such as " data are isolated ".
