Below for including external publicly-owned chain to external system, block catenary system provided by the embodiments of the present application is carried out
Explanation.
Fig. 1 and Fig. 2 is the schematic diagram of block catenary system provided by the embodiments of the present application.As shown in Figure 1, the present embodiment provides
Block catenary system, including：Management end 101, external publicly-owned chain 102 and user terminal 103.Wherein, the alliance of management end 101
Chain or privately owned chain and publicly-owned chain 102 use the identical account book data of logic 100.
In the present embodiment, management end, user terminal can be respectively the system for including one or more communication equipments.User
The number at end can be respectively multiple.However, the application does not limit this.
In the present embodiment, each block data on external publicly-owned chain by management end alliance's chain or privately owned chain it is more
A block data sequence forms.I.e. the alliance's chain or privately owned chain of management end and the bottom account book data of publicly-owned chain are logically same
The sequence of one account book data, account book is also associated successively.In this way, management end can check the data of itself by publicly-owned chain
State, and alliance's chain of complete management end or the data of privately owned chain can be recovered by publicly-owned chain.Wherein, the alliance of management end
Chain or privately owned chain are different from the common recognition algorithm that publicly-owned chain uses, so the time for respectively generating block data also differs；Management
Alliance's chain at end or privately owned chain use common recognition time shorter algorithm, to meet quickly confirmation and high frequency transactions demand, and it is publicly-owned
The common recognition time of chain is longer, therefore publicly-owned chain is an asynchronous process with respect to alliance's chain of management end or privately owned chain.Publicly-owned chain
On the quantity of block data that generates of each block data management end for including also be not fixed, for example, in Fig. 1, publicly-owned chain
On a block data may include management end generate three or four block datas；Therefore the connection of management end is not interfered with
The generation of alliance's chain or privately owned chain, to meet the high concurrent demand of management end.
In the present embodiment, the data for the alliance's chain or privately owned chain that management end generates all can be announced externally, asynchronous life
Outer publicly-owned chain in pairs.The data block of publicly-owned chain is multiple continuous data block combinations of the alliance's chain or privately owned chain by management end
Made of, the block head data of publicly-owned chain are only added, due to the accounting very little of block head data, so the data volume newly increased
Very little.Moreover, the data block that publicly-owned chain uses all is alliance's chain by management end or the block data after privately owned chain is packaged, because
This is also beneficial to the data exchange of publicly-owned chain.
In the present embodiment, alliance's chain of management end or the data on privately owned chain are divided into control data and transaction data two
Point.Control data are mainly the set for the information data that management end is issued for managing and controlling block catenary system, can be wrapped
Include the registration and unregistration of user, mechanism, the distribution of token, the fresh informations such as trading rules and key, certificate.Except the body of user
Part information is outside ciphertext, remaining most of data is all that in plain text, easily and effectively to supervise, can also protect the privacy of identities of user.
Transaction data is the set of all single transaction；Trading rules are issued by management end in controlling data, may include that transaction is double
Identity mark, number of deals, nonce values, timestamp, transaction ID (ID) and the additional information etc. of side, can also include user terminal
Authentication signature and management end endorsement signature；Wherein, it per transaction is required for that endorsement is verified and provided by management end
It can just come into force after signature, to achieve the purpose that management end is managed transaction.Wherein, the nonce values of transaction are one random
Numerical value；In addition to timestamp, transaction id and signature value are in plain text, remainder data is all ciphertext, and the authentication signature of user terminal is pair
The signature that the plaintext of the identity of both parties and the plaintext of nonce values and other ciphertext data carry out, and the back of the body of management end
Bookmark name is the signature for the entire transaction data submitted to user terminal, so can be signed with the endorsement at verification management end to outside,
But it is not able to verify that the authentication signature of user terminal, and can prevent violence from attempting the identity of both parties, protects both parties' body
Part privacy.
In the present embodiment, the alliance's chain or privately owned chain of management end can generate the State Tree of whole system, to obtain
The state of each account；And due to the privacy sharing sub-key of not no management end on publicly-owned chain, so whole system cannot be generated
Status data, but the bottom of the alliance's chain or privately owned chain due to management end and publicly-owned chain is used with a account book data, because
This, can obtain and accumulation account remaining sum on publicly-owned chain, more than the account in the State Tree of obtained account balance and management end
The state of volume is consistent.
In other words, for same a account book data, the occupation mode for management end and user terminal is different, management
End can generate the State Tree of system, and to learn the state of each account, and user terminal can learn the detailed of the every transaction of oneself
It counts evidence accurately, is consistent by adding up the account status that transaction results obtain and the state that management end obtains, also just by publicly-owned
Chain realizes the unalterable feature of customer transaction data, and management end can not forge the authentication signature of user terminal and change is handed over
Easy data, so that it is guaranteed that user's assets security.
In the present embodiment, the key of user terminal can be divided into two class of signature key and encryption key.Wherein, signature key
Locally generated by user terminal and management use, using can not derived hardware as carrier, to ensure that the safety of key makes
With.Signature key issues the authentication certificate of user terminal by CA (Certificate Authority, Certificate Authority) mechanism
Or eID mechanism is used, realize the real name authentication of user terminal.Encryption key is that user terminal passes through authentication certificate or eID
It after management end registration, is issued by management end, and is stored and used by the local wallet of user terminal.
Illustratively, encryption key may include the tagged keys of additive homomorphism, privacy sharing sub-key and symmetric cryptography
Key.For example, the identity information of user can use symmetric cryptographic key, storage is encrypted using symmetric encipherment algorithm；It hands over
The data such as the identity of easy both sides can use privacy sharing algorithm, and storage is encrypted using privacy sharing sub-key；It hands over
Easy number can use additive homomorphism algorithm, and storage is encrypted using the tagged keys of additive homomorphism.Wherein, symmetric cryptography refers to
It is encrypted and decrypted using same key using the both sides of this Encryption Algorithm.Privacy sharing refers to classified information with appropriate
Mode is split as N parts, and only M parts of cooperation could Restore Secret message.It, can after additive homomorphism encryption refers to message by public key encryption
The operation of addition is carried out in ciphertext, operation output is decrypted using private key, and result is original with use addition process unencryption
The result that data obtain is consistent.
In the present embodiment, the data on publicly-owned chain are externally able to validate only the complete of the data block that alliance's chain or privately owned chain are packaged
The endorsement signature of the management end of whole property and verification per transaction, and can check the cleartext information that management end is issued in controlling data
With the transaction id and timestamp information in transaction data, other information is all externally kept secure.
In the present embodiment, user terminal may be adapted to, by transaction id, relevant transaction data be retrieved in account book data.
I.e. user terminal can be by transaction id, in the upper relevant transaction data of retrieval of at least one of management end and external publicly-owned chain.
Wherein, the wallet of user terminal is the wallet of a lightweight, does not need to complete publicly-owned chain data；The wallet of user terminal can be with
From publicly-owned chain decryption check oneself account information and with oneself relevant transaction data, such as the body including both parties
Part mark, the number of deals of oneself, and it is able to verify that the authentication signature of transaction data and endorsement are signed.Moreover, the wallet of user terminal
The balance amount information added up after all and oneself relevant transaction data decryption, with the account balance ciphertext inquired from management end
Information after decryption is consistent.
The mode for retrieving relevant transaction data from publicly-owned chain to user terminal below illustrates.
Since transaction data is associated with sender and recipients, transaction id, which can be divided into, sends ID and reception ID two
Part.Wherein, list can be passed through by the nonce values of user terminal last time transmission transaction and the symmetric cryptographic key of user terminal by sending ID
To can not inverse function generate, send ID be unique in systems；Receive ID by user terminal last time receive transaction nonce values and
The symmetric cryptographic key of user terminal by unidirectionally can not inverse function generate, the reception ID at different user end is unique in systems
, but because there are concurrent transactions, therefore there are the same user terminals for different transaction reception ID having the same.
Wherein, user terminal generates a random nonce value and initial reception when being registered to management end by management end
ID, and storage is encrypted using the symmetric cryptographic key of user terminal, and recorded in the State Tree of management end.Transaction when by
In State Tree the symmetric cryptographic key of the nonce values of sender and user terminal by unidirectionally can not inverse function generate send ID, even
Reception ID with recipient in State Tree forms transaction id.Nonce values are generated at random by management end, and are ensured calculated next
A transmission ID and reception ID is unique in systems.Management end passes through the identity of nonce values and both parties secret
Close shared algorithm is encrypted, and is transferred to user terminal together with transaction id.After user terminal submits transaction data, management end can be with
Whether the transmission ID of verification user terminal meets, and verifies and receive whether ID belongs to recipient, then more according to the nonce values of transaction
The nonce values of sender in new state tree, and whether search the reception ID in transaction data identical as the reception ID in State Tree,
If identical, it is updated according to the calculated reception ID of nonce values.It can be seen that the transaction data of user terminal is according to hair
It send and receives and respectively constitute a chain, and due to concurrent transaction, there are the brothers of synchronization on reception chain
Node.In other words, the transaction data of user terminal forms a transmission chain and a reception chain for having the brotgher of node.
Wherein, the wallet of user terminal can by user identifier search account information, decryption registration when nonce values and just
Begin to receive ID, transmission ID next time can be calculated, inquiry sends ID and receives ID on publicly-owned chain respectively, and then gets
All transmission transaction related to user and reception transaction.Nonce values are it is known that also in the transaction data submitted due to user terminal
Next transmission ID is determined, whether the transmission ID that user terminal can be transferred to verification management end meets.And each send ID
It has confirmed that, also it is prevented that Replay Attack.By transaction id and nonce values, the transaction data of user terminal forms a transmission
Chain and a reception chain for having the brotgher of node, and user terminal can easily be retrieved by transaction id on publicly-owned chain
Transaction data, and outside can not be learnt.The wallet of user terminal can use poll or subscribing manner to be looked into from publicly-owned chain
Ask transaction id, preserve with the relevant All Activity data of user terminal, the account status of user terminal can be analyzed, so as to management end
Carry out inquiring and authenticating.
In the exemplary embodiment, user terminal can be adapted in block catenary system establish trustship contract, and pass through
Contract ID retrieves relevant contract data on to external system.
In the present embodiment, the common recognition reward on publicly-owned chain is that management end records the account information to be rewarded on publicly-owned chain,
After waiting for the block data of such as 6 publicly-owned chains to confirm, publication is rewarded into corresponding account in plain text in controlling data, and is tired out
It counts in account balance ciphertext.Common recognition reward on i.e. publicly-owned chain, meeting are issued in the data block below by management end, and
By knowing together reward to ensure the data of publicly-owned chain on journal management end submission, specific reward rule can be by management end
It makes by oneself.In this way, the balance amount information that the wallet of user terminal is inquired from publicly-owned chain, it is also necessary to add up the common recognition reward on publicly-owned chain,
Just it is consistent with the account balance state of management end.And reward of knowing together is by issuing in plain text, so can by user identifier
It is retrieved on publicly-owned chain.Token total amounts to ensure in system are certain, and management end can be when issuing token, reserved part
Token is not diverted into the account balance of issuer, as the common recognition reward on publicly-owned chain.
In the exemplary embodiment, as shown in Fig. 2, the block catenary system of the present embodiment can also include：Supervise end 104
And third party 105；Wherein, end 104 is supervised, is suitable for the endorsement token that regulatory management end 101 is issued, and in management end 101
Mandate under, supervise transaction data and account information；Third party 105, are suitable under the mandate of user terminal 103, supervision transaction
Data and account information.
In this example, for the behavior at effective regulatory management end, supervision end can provide automatic supervision and artificially participate in
Supervise two parts function.Automatic supervision can be on the alliance's chain or privately owned chain of management end, also can be on publicly-owned chain.Automatic supervision exists
The privacy sharing sub-key of management end can be obtained when startup, so corresponding system mode tree can be generated, be able to verify that every transaction
Authentication signature and endorsement sign, and according to every transaction using additive homomorphism algorithm modification State Tree in account balance it is close
Text does not leak relevant account balance information.In order to verify the validity of every transaction number, management end also needs to provide
One black box authentication module by audit, function are to input the account of the number ciphertext and mark and payer of both parties
Family remaining sum ciphertext decrypts number in black box authentication module and verifies whether to meet, returns to success or not.Automatically the mesh supervised
Be verify whether all numbers of deals meet, it is ensured that the total amount of token is certain in system.And the prison artificially participated in
A pipe part is the clear data issued in controlling data by regulatory management end, the main token for including management end distribution
Endorsement, for example need signature of the management end with the proof such as underlying assets mortgage or guarantee fund and with regulator that could issue
The token accordingly to endorse；Another part is the account information for needing certain user in supervisory systems, and management end can authorize accordingly
The encryption key of user terminal gives supervision end, supervision end that can decrypt and check the transaction data and account information of corresponding user.
In this example, third party need check user terminal account information when, user terminal can authorize encryption key to
Third party, so that third party checks on publicly-owned chain.
In the present embodiment, automatic supervision is able to verify that the validity of number of deals, it is ensured that the total amount of token is one in system
Fixed.The variation of token total amounts needs management end to issue or remove in plain text respective numbers in controlling data in system
Token increases or decreases corresponding number ciphertext in its account balance, reaches adjustment system by specified issuer
The purpose of middle token total amounts, and these information are all disclosed in plaintext.General transaction in chain needs the certification with user terminal
Signature can just come into force, and signature key be user terminal local management can not be derived, and be bundled with the authentication card of user terminal
Book uses eID mechanism, and user terminal can be verified on publicly-owned chain and the authentication signature of oneself relationship trading, so management end is not
The authentication signature and transaction data that change user terminal can be forged, so that it is guaranteed that user's assets security.In addition, there is pipe for multiple
The block catenary system of end endorsement is managed, user terminal registration need to only be used with a authentication certificate or eID, convenient for users
And update.
Referring to Fig. 3 and Fig. 4, the stream compression between multiple block catenary systems with management end endorsement is said
It is bright.Fig. 3 and Fig. 4 is respectively that the interchain circulation schematic diagram between two block catenary systems provided by the embodiments of the present application shows with interaction
It is intended to.It is illustrated so that two with the block catenary system of management end endorsement as an example in figs. 3 and 4.
In the exemplary embodiment, at least two block catenary systems establish cryptochannel by management end and carry out data flow
Turn, wherein the token total amounts in either block catenary system remain unchanged, and related contract data stores in respective system.
In this example, stream compression is by each system between multiple block catenary systems with management end endorsement
Cryptochannel realization is established between management end.As shown in Figure 3 and Figure 4, lead between block catenary system SA and block catenary system SB
It crosses respective management end and establishes cryptochannel.Wherein, important data are not stored on cryptochannel, only be used as data agreement and
The channel of contract is triggered, specific user's contract data all stores on each block catenary system, and therefore, user terminal can be right
Relevant contract data is inquired on the publicly-owned chain answered.Corresponding contract rule is issued by each management end in controlling data, and
By associating across chain and about ID, the contract data of stream compression between different system, the wallet of user terminal can be analyzed
The executive condition of related contract.
As shown in figure 4, when carrying out stream compression between multiple block catenary systems, need both parties in the system to be circulated
In registered.For example, user A is registered to the management end of block catenary system SA and SB, user B to block catenary system SA and
The management end of SB is registered.Since the user terminal of both parties is not aware that whom the other side of transaction is, so being held in the palm
Pipe contract is stated.Wherein, the trustship contract of statement may include the people of trustship, the number ciphertext of trustship, timestamp, nonce values,
The authentication signature etc. of about ID, additional information and user terminal can also use the rule of above-mentioned transaction id with about ID here, with
User terminal is facilitated to be retrieved on publicly-owned chain.After management end verifies the trustship contract of user terminal and signature of endorsing, contract just comes into force.
Management end in the account balance of user terminal from subtracting in corresponding number ciphertext to newly-built contract remaining sum.The contract of trustship is merchandised
The authentication signature of user terminal is then no longer needed, passes through between the management end of block catenary system and negotiates and trigger, generate relevant conjunction

In across chain and about ID, so that it may on another publicly-owned chain of corresponding circulation retrieval comprising should be across the relevant contract of chain and about ID
Transaction.Decryption can check the contents such as relevant contract transaction content, including timestamp, number of deals, contract information, and can test
The endorsement signature of management end is demonstrate,proved, but can only check corresponding trustship and about ID, and cannot check the identity of trustship contract.With
The wallet at family end gets relevant trustship contract information and respectively after the circulation contract Transaction Information of two systems, so that it may with
The executive condition of the related contract of analysis.
In this example, between multiple block catenary systems endorsed with management end, the contract of both parties' user terminal
Transaction can't influence the variation of token total amounts in respective system, the mistake that only different user token circulates in both sides' system
Journey.And the validity of number of deals can be also verified by supervising automatically, it is ensured that the total amount of token is certain in system.And
Between multiple block catenary systems endorsed with management end, after management end mutually establishes relevant cryptochannel, so that it may with
Realize circulation of the user data between system, and the data to circulate all recorded on corresponding publicly-owned chain and can inquiring and authenticating,
It is also convenient for being supervised.
