Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
The technical solution of the embodiment of the present invention is related to exchanging the chain currency of different blocks chain, and the program is especially suitable
For super chain network.In order to facilitate understanding, super chain network is introduced first.
Super chain network includes a plurality of block chain, can be classified for basic chain and parallel chain.Wherein, basic chain is a kind of block
Chain can be used for establishing connection between various independent block chains.Basic chain can be associated with corresponding parallel chain, be used
Data exchange is carried out in auxiliary establishing parallel chain, management parallel chain, auxiliary parallel chain.For example, basic chain can be used for existing
Block chain independent of each other between establish connection so that the data interaction in block chain is no longer limited to an individual block
Chain, so that the flow range of value is no longer limited to an individual block chain.That is, basic chain can be to entire block link network
Operating parameter in network is managed and supervises.
Parallel chain is also a kind of block chain, is opposite concept with basic chain.Parallel chain has all of general block chain
Attribute, meanwhile, it may go to establish, be managed and carry out data exchange based on basic chain.Parallel chain can be by basic chain
Made of derivation, or be also possible to have the function of with basic chain reciprocity status and, mutually auxiliary is established, is managed and data friendship
It changes.Parallel chain can have one, and there may also be a plurality of.And optionally, between a plurality of parallel chain independently of one another, not mutual shadow
It rings, alternatively, being also possible between two parallel chains mutually for the relationship of basic chain and parallel chain.
In general, basic chain is established and is run prior to parallel chain, with higher public credibility, appeal, value
More obtain everybody approval.So the node of parallel chain can use public credibility and the appeal of basic chain node come by being ready
The node for providing calculation power provides service for it.
Basic chain and parallel chain can form super chain network.In super chain network, basic chain be also possible to one or
It is a plurality of.It should be noted that between all nodes of the basic chain of participation and all nodes for participating in parallel chain, there are overlapping relations.
That is, at least partly node of participation parallel chain and participate in basic chain are at least partly identical block chain nodes.At these
In the block chain node of overlapping, it is deployed with all data of the block chain of its participation, that is, be both stored with the deployment number of basic chain
According to being also stored with the deployment data of parallel chain, also while being stored with the block itself of basic chain and parallel chain.Due to disposing simultaneously
There are the data of different blocks chain, so the transactions requests of different blocks chain can be generated in such block chain node, and may be used also
With local search to the Transaction Information in different blocks chain, it is facilitated to carry out across chain issued transaction.
In addition it should be noted that, basic chain and parallel chain can be swashed using the chain currency of identical or different type
Encourage, and the block chain node of basic chain and parallel chain can be stored simultaneously for the account of storage chains currency it is a variety of different types of
Chain currency, the chain currency in each block chain can be interacted with account, such as be transferred to or produce chain currency.Block chain plays
Incentive action is not limited to chain currency, is also possible to other by the element of account management, such as digital gift, therefore can manage
It solves, chain currency alleged by the embodiment of the present invention, can have economic value to be any, or have the element of incentive action to participant.
Wherein, account can be through asymmetric key pair and manage, and public key is exactly account address, and private key is owned by account
Person oneself saves.
In embodiments of the present invention, basic chain can be existed simultaneously in block chain network and parallel chain is two distinct types of
Block chain.Wherein, parallel chain can be a derivative block chain from basic chain, basic chain can be provided for parallel chain across
Chain service.The node for participating in parallel chain some or all of can be in basic chain node, wherein the node for participating in parallel chain exists
The operation of participation parallel chain can be independently chosen whether before participating in parallel chain network.
In an alternate embodiment of the present invention where, block chain node is stored with basic chain and parallel chain, Yi Jicun simultaneously
Contain the deployment data of basic chain and parallel chain.
Wherein, deployment data can be data Layer in block chain, network layer, common recognition layer, excitation layer, contract layer and application layer
Corresponding data, such as data block, timestamp, mechanism of transmission, authentication mechanism, issuing mechanism, algorithm mechanism, intelligent contract or can
Program the data such as currency.
In embodiments of the present invention, block chain node can be can handle simultaneously basic chain network in parallel chain network
The node of transactions requests, thus can memory block chain network deployment data corresponding with parallel chain network simultaneously, and can be same
When store the block chain Transaction Information of basic chain and parallel chain.
Embodiment one
Fig. 1 is the flow chart for the chain currency conversion method based on block chain that the embodiment of the present invention one provides, the embodiment
It is applicable to handle the chain currency conversion of any two block chains in super chain network, is especially by the currency conversion of parallel chain
The currency of basic chain.It is primary exchange need by the source currency and target currency exchanged respectively belonging to the participation of block chain node, match
It closes to execute and completes dialogue.Certainly, the node for belonging to two block chains can be the same physical equipment.The present embodiment is by being configured at
First block chain node is executed based on the chain currency exchanging device of block chain, which can use software and/or hardware
Mode realize.
As shown in Figure 1, this method comprises:
S110, the first currency conversion transactions requests are obtained, wherein the first currency conversion transactions requests are used for first
Source currency conversion in promoter's account of block chain is the target currency of the second block chain；
First currency conversion transactions requests can be the form of intelligent contract, can be sent out by the arbitrary node of the first block chain
It rises.Optionally, the first block chain is certain parallel chain, and the second block chain is basic chain, also referred to as main chain.The public credibility of basic chain is more
Height, currency more have economic value, and parallel chain currency conversion is more for the demand of basic chain currency.
First currency conversion transactions requests embody the demand by source currency conversion for target currency.A variety of sides can be passed through
Formula specifies the number to be exchanged, such as, it is possible to specify source amount of money to be exchanged, or the specified target currency number to be exchanged
Volume can also be specified simply and exchange whole source currency in promoter's account.
S120, it is handled according to the first currency conversion transactions requests, by source Money transfer to be exchanged to setting
Account is destroyed to be forbidden to use, and forms the first exchange Transaction Information and is added in the block of the first block chain；
The node of first block chain can be block and generate node or non-block generation node, can be to first currency
It exchanges transactions requests to be handled, specifically may include determining to exchange number, while determining that account is destroyed in setting, by source Money transfer
It is destroyed in account to setting, the transfer procedure is similar with conventional transfer procedure.It sets and destroys account as dedicated account, in the account
Source currency be no longer participate in circulation, forbid being used.The setting can specifically be destroyed to the address setting of transferring accounts of account
Address state is transferred accounts to be forbidden to use, to realize that the chain currency in account is unavailable for sky, or setting.It can be set in creation
Above-mentioned setting is carried out when destroying account, for example, regular account number will create asymmetric key pair when creating, and setting destruction account can
To abandon private key, or private key is not issued, chain currency can be shifted outward from the account from without user.Account is destroyed in setting
Public key address can carry in the first currency conversion transactions requests, or can be only fitted in the deployment data of node for obtaining
It takes.
The first exchange Transaction Information that node processing is formed, also typically includes to whether transferring accounts for account is destroyed in setting
It executes, and various specifying informations, such as the mark of promoter's account for transferring accounts etc..First exchange Transaction Information is added to institute
In the block for stating the first block chain, to prevent from distorting, and for inquiring and authenticating.
S130, second-cash exchange transactions requests are initiated to the second block chain network, wherein the second-cash exchanges thing
Business request is handled for requesting the block of the second block chain to generate node, Transaction Information is exchanged according to described first, by mesh
Money transfer is marked into promoter's account.
As previously mentioned, block chain node is deployed with the deployment data of the first block chain and the second block chain simultaneously, so can
Transactions requests are exchanged to initiate the second-cash.
It can be automatically initiated by the node of the first block chain, middleware initiation or user is assisted manually to initiate the second-cash and convert
Transactions requests are changed, the second-cash is sent to the second block chain network from the first block chain node and exchanges transactions requests.The second-cash
Transactions requests are exchanged to be used to that the second block chain to be requested to complete the process for shifting target currency to promoter's account.Assist middleware
Can be other can interact with node, the equipment of triggering transactions requests initiation or software package etc..
First currency conversion transactions requests and the second-cash exchange transactions requests, are equivalent to transactions requests of once transferring accounts,
In conjunction with the redemption process for completing a chain currency.
After the node of the second block chain, which receives the second-cash, exchanges transactions requests, it can be converted according to first wherein carried
The Transaction Identifier for changing Transaction Information inquires first from the first block chain and exchanges Transaction Information, to verify transferring accounts for source currency
Whether process is correct and executed, if being verified, target currency is transferred accounts into promoter's account, completes to exchange
Process.
Technical solution provided by the embodiment of the present invention is carried out using the transactions requests of transferring accounts that two block chains execute respectively
In conjunction with realizing the redemption process of two kinds of chain currency.Itself all chain is respectively executed according to rule is transferred accounts by two block chains
Currency is transferred accounts, and within a block as Transaction Information record, guarantees its credibility.
In the above scheme, target currency can be produced from any account, but preferably be supported by block chain
This is exchanged, i.e., preferably, the second-cash exchanges transactions requests and is used to request the block generation node of the second block chain to be handled,
Transaction Information is exchanged according to described first, target currency is transferred accounts from the chain account of the first block chain to promoter's account
In.
Chain account can be an account for belonging to block chain, it can be used for management of the matchmaker in block chain for transaction
It is situated between, such as the elements such as digital cash or other articles that can be used for trading.Account in chain account and existing block chain network
Difference be that can not be provided that its is operated by intelligent contract by the control and management of user.With the account of chain account relating
Transactions requests can be the initiation of block chain node, for requesting to establish the transactions requests of chain account, or be also possible to request
It changes chain account or carries out the transactions requests of currency operations in chain account.Currency operations generally may include the place for being transferred to and producing
Reason.Account transactions requests to contain or generate and be capable of the account intelligence contract of Quality Initiative account, account intelligence contract is written into
In block, guarantee its reliable execution.
It should be noted that mainly including user account and alliance's account in existing block chain field.Wherein, user's account
It number can be the account of user oneself, the not stringent corresponding relationship of the node in user and block chain network.That is, a use
Family can correspond to several nodes, and a node can also carry several users, and not have fixed correspondence between node and user
Relationship.User can be by the account data of the public key and Private key management oneself of oneself, for example, the number in management user account
Currency.User can be traded with the digital cash in oneself account, payment procedure expense, reward and provide frozen capital
Etc. any operation.Alliance's account can be more accounts people unified management and used.If alliance's account want to carry out transaction and
Reward etc. is related to the operation of digital cash, and the agreement of all members or large scale member in alliance is needed to agree to just can control connection
The digital cash of alliance's account operates.Alliance's account may be generally employed in alliance's chain, belong to the tissue such as company or mechanism.By
This is as it can be seen that account usually can be managed and be controlled by one or more users in existing block chain network.
However, if there is a block chain in block chain network incessantly, but there are a plurality of parallel chains.Parallel chain is being created
During building or running, it is also desirable to some to be related to the affairs of digital cash in account.But existing user account or connection
Alliance's account can not exactly match demand of the parallel chain to digital currency operations.For example, when creation parallel chain, in block chain network
Whether node can obtain income without being willing to participate in and providing calculation power due to uncertain.It is parallel in order to encourage node to participate in creation
Chain can be provided certain digital cash bonus by parallel chain founder and be motivated.But due to parallel chain founder couple
The user account or alliance's account of oneself have absolute control.Therefore, when parallel chain founder needs to change, Huo Zheping
When row chain creation person goes back on one's word to the bonus of offer, excitation not can guarantee centainly in place.
In embodiments of the present invention, it can be solved the above problems by the way that chain account is arranged in block chain network.Chain account
Number it can be used for storing chain element, i.e. chain currency, and chain account can not be by the control and management of any user.Chain account is public
It opens transparent and there is no private key, account operation can only be controlled by the account intelligence contract bound when the creation of chain account.Cause
This, chain account has enough public credibility for existing account, can guarantee the validity motivated to network node
And reliability.
The chain account of block chain and its account intelligence contract, in the block that can be written into this block chain itself, preferably
It is in write-in wound generation block.Alternatively, it is also possible to be written in the block of other block chains, supervised by the node of other block chains another
The execution of the chain account of one block chain.
Therefore, in the embodiment of the present invention, can also include:
Obtain the account transactions requests with chain account relating, wherein the chain account belongs to the first block chain；
Account intelligence contract is obtained from the account transactions requests, and the first block chain is written into the account intelligence contract
Block in, wherein the account intelligence contract is for being transferred to target currency to the chain account when executed.
In general, chain account can be established while block chain creation.If the target currency quantity in chain account is very
It is few, then it can be transferred accounts by way of intelligent contract into chain account.The currency of chain account is transferred to unrestricted, and currency produces then
It is ensured by the execution of intelligent contract.
Other chain currency in chain account allow as the foundation of the first block chain public credibility of support by the first block chain
Source currency conversion be chain account target currency, but also the enthusiasm that user participates in the first block chain is higher, without holding
The uncertain economic risk of load source currency.In addition, chain account belongs to the first block chain, it is the public guarantee as block chain, no
It is controlled by individual subscriber, also further improves its public credibility.
