Abstract
The present invention disclose it is a kind of for alliance's chain across catenary system and across chain method, should include for carrying out the sequence module of sequential search to across the chain transaction of submission, for monitoring and verifying the monitorings module across chain transaction, the execution module for trading come the authentication module for verifying the authenticity traded across chain and execution across chain according to the signature across chain transaction that block chain is thrown off across catenary system.The present invention solves the problems, such as the information of alliance's interchain and value across chain, and block chain is allow to possess the function of calling other block chains, carry out value transmission.
Description
Technical field
The present invention relates to block chain intelligence contract, across chain, common recognition algorithm more particularly to it is a kind of for alliance's chain across linkwork
System and method.
Background technique
Intelligent contract (English: Smart Contract) is that one kind is intended to that conjunction is propagated, verified or executed in a manner of information-based
Same computer protocol.The permission of intelligent contract carries out credible transaction in no third-party situation, these transaction it is traceable and
It is irreversible.
In the problems that block chain is faced, intercommunity high degree limits answering for block chain between block chain
Use space.No matter across chain technology is exactly the key of realized value internet from the point of view of publicly-owned chain or privately owned chain, it is area
The good medicine that block chain is saved out from the isolated island of dispersion is the bridge that block chain is expanded and connected outward.
Summary of the invention
In view of the deficiencies of the prior art, the present invention disclose it is a kind of for alliance's chain across catenary system and across chain method, specifically
Technical solution is as follows:
It is a kind of for alliance's chain across catenary system, which is characterized in that the system includes following module:
Sequence module, for carrying out sequential search to across the chain transaction of submission, if it find that the case where losing, then by coming
The loss that source chain provides obtains across the chain transaction lost across the interface that chain is traded；
Monitor module, across the chain transaction being thrown off for monitoring block chain, according to different common recognition algorithms, reading it is multiple across
Chain transaction is verified for authentication module；
Authentication module, for according to it is described across chain transaction signature come verify across chain transaction authenticity, i.e., whether be
Approve whether across the chain transaction that node is signed, and across chain transaction are identified；
Execution module, for convert the transaction data structure across chain transaction for the structure of purpose chain, and by turn
Transaction after changing is sent to purpose chain.
A kind of across chain method for alliance's chain, which is characterized in that this method is based on above-mentioned across catenary system realization, across chain
Carry out two block chains across chain in transaction and be respectively defined as source chain and purpose chain, it is described across be responsible for receiving in catenary system across
The node of chain transaction and sequencing is witness, is somebody's turn to do across chain method and specifically comprises the following steps:
S1: participate in that the nodal information of oneself, event are dished out interface message by source chain across chain and purpose chain and contract limits
Condition processed is registered to described across in catenary system；
S2: the witness across in catenary system receives across the chain transaction of the source chain, and verifies across chain transaction
Authenticity and sequence；
S3: the witness selects switching strategy according to the purpose chain type that indicates in across the chain transaction, will be across
Chain transaction is converted into the structure of deal that purpose chain can identify and transaction is sent to purpose chain；If across the chain transaction is
There is receipt, then the witness also needs the call back function indicated according to source chain type and across chain transaction to convert receipt
Receipt transaction is simultaneously sent back source chain by the structure of deal that can identify for source chain, the process of return also need it is described across
Catenary system verifies the authenticity and sequence of across chain receipt transaction.
Further, described to be selected to determine that across the chain transaction is true according to the common recognition algorithm of block chain across catenary system
The algorithm of reality.
Further, across the chain transaction needed before being spilled over by block chain node sign could be by described across linkwork
System is approved.
Further, the monitoring module across each node in catenary system collects across chain transaction, to prevent from seeing
Card person does evil to which purposive discarding is traded.
Beneficial effects of the present invention are as follows:
The present invention solves the problems, such as the information of alliance's interchain and value across chain, possesses block chain and calls other blocks
Chain, the function of carrying out value transmission.
