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 various embodiments of the present invention is realized based on super chain network, wherein super chain network is by basic link network
Network is formed with parallel chain network.For the technical solution for clearly introducing subsequent embodiment, it is situated between first to super chain network technology
Continue explanation.
Wherein, basic chain is a kind of block chain, can be used for establishing connection between various independent block chains.Basic chain
It can be associated with corresponding parallel chain, carry out data friendship for auxiliary establishing parallel chain, management parallel chain, auxiliary parallel chain
It changes.For example, basic chain can be used for establishing connection between existing block chain independent of each other, so that the data in block chain
Interaction 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 managed and supervise to the operating parameter in entire block chain network.
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.
In parallel chain creation, basic chain transactions requests can be initiated by arbitrary node, including the area parallel chain Chuan Shi
The content of block, i.e. parallel chain dispose data.By the node processing of the basic chain transactions requests, the creation operation of parallel chain is recorded,
It also corresponds to be notified of each node in network simultaneously, finally receives and deploy the node of parallel chain data, just take part in flat
Row chain can then handle parallel chain transactions requests.
Basic chain network can form super chain network with parallel chain network.In super chain network, basic chain can also be with
It is one or more.It should be noted that participating in existing between all nodes of basic chain and all nodes of participation parallel chain
Overlapping relation.That is, at least partly node of participation parallel chain and participate in basic chain are at least partly identical network nodes.
In the network node of these overlappings, it is deployed with all data of the block chain of its participation, that is, be both stored with the deployment of basic chain
Data are also stored with the deployment data of parallel chain, go back while being stored with the block itself of basic chain and parallel chain.So-called deployment number
According to including communication mechanism data needed for participating in block chain, common recognition mechanism, intelligent contract, transactions requests script and other need
The data wanted.Due to being deployed with the data of different blocks chain simultaneously, so different blocks chain can be generated in such network node
Transactions requests, and its can be facilitated to carry out across chain issued transaction with local search to the Transaction Information in different blocks chain.
Due to being deployed with the data of different blocks chain simultaneously, so different blocks chain can be generated in such network node
Transactions requests, and it can be facilitated to carry out across chain issued transaction with local search to the Transaction Information in different blocks chain.?
In node, it is based on setting program, can trigger and be initiated in another block chain when monitoring certain behavior of a block chain
Transaction request.For example, the node can be application service platform, two or more block chains are supported simultaneously, and can be with
Issued transaction or block chain management between a plurality of block chain of cross correlation.
It should be noted that the block chain node for participating in super chain network can be and have higher data operation, storage
And the full node of transmittability, it can also be the block chain network section of not stored or storage section block data and Transaction Information
Point lightweight node.
Lightweight node is similar with full node, is deployed with the deployment data of block chain, such as intelligent contract, common recognition mechanism,
Therefore the transactions requests interactive process of block chain can be participated in, but does not store all block datas.When lightweight node needs
When inquiring Transaction Information in block, it can be obtained in real time to other nodes, and setting means is taken to be verified.
Lightweight node can be generally deployed in terminal device, require lower, lightweight node to the hardware configuration of equipment
It can be integrated in operating system level, the hardware in terminal device is controlled, while can be interacted with upper application software, to answer
The support of block chain is provided with the function of software.
Further, explanation is introduced to the concept of chain account involved in various embodiments of the present invention.Chain account can be with
An account for belonging to block chain, it can be used for management of in block chain for transaction medium, such as digital cash or its
The elements such as the article that he can be used for trading.
Chain account and the difference of account in existing block chain network be, can not by the control and management of user, but
Provide that its is operated by intelligent contract or other approach.Chain account is usually bound with block chain, can be provided and the integrated operation of block chain
The relevant account element operation of behavior is supported.Wherein, element operation generally may include the processing for being transferred to and producing.And carry out account
When element operation, account transaction request can be initiated from block chain network node to block chain network, account transactions requests can
To be the transactions requests for requesting to establish chain account, or it is also possible to request change chain account or carries out chain account interior element
The transactions requests of operation.Since account transaction request includes or can be generated and is capable of the account intelligence contract of Quality Initiative account, because
This is written into block when account intelligence contract, that is, can 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
Family 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.
Chain account can be used for storing chain element, and chain account can not be by the control and management of any user.Chain account
It is open and clear and does not have private key, account operation can only be controlled by the account intelligence contract bound when chain account creation
System.Therefore, chain account has enough public credibility for existing account, can guarantee have to network node excitation
Effect property 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.
The address of chain account can be nature semanteme field.Since chain account is not by the control of user and management, as long as energy
It is enough to be identified by node.There is no need to chain account setup regular length public key address and corresponding private key, can adopt
The address of chain account is named with naturally semantic field, such as uses readable English word.
