Referring to Fig. 2, in practical implementation, changes original node and generate for modifying the second block chain treaty content
Intelligent contract is updated, and broadcasts the update intelligence contract (step by changing original node private key signature to the first block chain network
Rapid 1) block chain contract can be modified according to Vehicles Collected from Market variation by changing original node, certainly, in order to avoid some change wounds
Beginning node holds inaccurate market trends, alternatively, illegal more new block chain contract of disrupting the market, alternatively, the original section obtained
The current information inaccuracy of point, it is also necessary to other original nodes are verified to intelligent contract is updated, specifically, other original sections
The update intelligence contract of node private key signature, and the section for changing original node that application obtains in advance are originated in point reception by changing
Point public key verifications change original node private key signature (step 2), if being verified, parse the intelligent contract of update and obtain the secondth area
Block chain modification information, if the second block chain modification information of confirmation, to the broadcast of the first block chain network by itself original node
The update intelligence contract of private key signature, when knowing that the original nodes of all other all carry out private key signature to updating intelligent contract
Afterwards, then show the intelligent updating contract in accordance with market trends, thus, the conjunction for updating intelligent contract is broadcasted to the second block chain network
About set up message (step 3).
After new block chain contract is set up, control block chain implements block chain business according to the new block chain contract,
Specifically, accounting nodes receive the contract establishment message for updating intelligent contract, and parsing updates intelligent contract and obtains the second block chain
Modification information, and determine the corresponding change type (step 4) of the second block chain modification information, if knowing the second block chain change letter

Enter and exit, substantially increases the stability and flexibility of block chain.
Fig. 3 is the flow chart of the contract adjustment processing method of block chain according to an embodiment of the invention, and this method is answered
For in the first block chain and the second block chain, wherein the first block chain is used to record the change scheme of the second block chain, and first
Composition node in block chain is usually original node, which can be interpreted as by equity holding side or authority
Alliance's chain of higher organization's composition, the second block chain can be the block life for meet the transactional services of market needs
At super block chain, as shown in figure 3, this method comprises:
Step 101, it changes and originates the update intelligence contract that node generation is used to modify the second block chain treaty content, and to
The update intelligence contract of node private key signature is originated in the broadcast of first block chain network by changing.
Wherein, the second block chain contract includes that block generates format (Format Type, common recognition mechanism including mechanism of knowing together
Parameter, block generating algorithm etc.), the concrete condition variation of original node (including originating the addition of node and exiting, originate node
Allocation of Equity variation etc.) etc..
It is appreciated that original node variation the case where detecting above-mentioned original node is changed, alternatively, the change of the market demand
Change (for example the business model of Vehicles Collected from Market is more adapted to the block generating mode of another format, or, the block of another format
Generating mode is safer etc. relative to current web technology) when, in order to guarantee that the second block chain adapts to this application environment
Variation may update the second block chain contract based on variation, alternatively, the new suggestion of intelligent contract is proposed, to build according to this
View updates the second block chain contract, and broadcasts the update intelligence by changing original node private key signature to the second block chain network
Contract.
It should be noted that in an embodiment of the present invention, authentication is carried out to node based on public key certificate technology, it is public
Key certificate technique and core be a pair of secret keys, the basic principle is that: the information content encrypted by a key, Zhi Nengyou
Another paired key just can be carried out matching.Encrypted public key can widely issue correspondent related with oneself i.e. its
His node, encryption key then need to store fool proofly.In use, interdependent node is using private key to block broadcast message
It is signed and sends other nodes to, the public key that the interdependent node can be used in other nodes completes the body to the interdependent node
Part certification.
Step 102, other original nodes receive the update intelligence contract by changing original node private key signature, and apply
The node public key verifying of the original node of the change obtained in advance is changed original node private key signature and is parsed more if being verified
New intelligence contract obtains the second block chain modification information, if the second block chain modification information of confirmation, to the first block chain network
Update intelligence contract of the broadcast by itself original node private key signature, when knowing other all original nodes all to updating intelligence
After energy contract carries out private key signature, the contract establishment message for updating intelligent contract is broadcasted to the second block chain network.
Understandable to be, current application scene may not adapted to by changing the update intelligence contract that original node generates
Real change, for example, without the objective real change etc. for reacting original node, it is then desired to which other original nodes are tested jointly
Whether legitimate demonstrate,prove the update intelligence contract.
Specifically, other original nodes receive the update intelligence contract by changing original node private key signature, right first
The node public key verifying of the original node of the change that the legitimate verification of the sender of the update intelligence contract, i.e. application obtain in advance
Original node private key signature is changed, if unanimously, showing that sender's legitimate verification passes through, thus, parsing updates intelligent contract
The second block chain modification information is obtained, whether legitimate, if by grinding if further verifying the second block chain modification information
The real change for confirming that the second block chain modification information adapts to current application environment is studied carefully, for example, objective react original node
Real change, then confirm the second block chain modification information.
Confirm that the original node of the second block chain modification information originates section by itself to the broadcast of the first block chain network
The update intelligence contract of point private key signature, to launch oneself affirmative vote, when knowing other all original nodes all to update
After intelligent contract carries out private key signature, then show that all original nodes have all launched affirmative vote, thus to the first block link network
The contract that network broadcast updates intelligent contract sets up message.
Wherein, the node that the contract establishment message for updating intelligent contract is broadcasted to the first block chain network can be alliance's chain
In any one original node, for example be any one node changed in original node or other original nodes,
This is with no restriction.
Certainly, in some possible examples, possible second block chain modification information can not obtain all original nodes
Approval, in this case, the original node that do not approve can improve the second block chain modification information, with make up change wound
The mistake of beginning node, specifically, the second block chain modification information, the original node not confirmed can be to the secondth areas if not confirming
Block chain modification information is modified, for example, the information for including in initial second block chain modification information is that " original node 1 moves back
Out ", and original node that the discovery of original node that this does not confirm is exited further includes original node 2, at this point, the original section not confirmed
Modification intelligence contract o'clock to the broadcast of the first block chain network by itself original node private key signature, for example, to the first block
Chain network broadcast is the modification intelligence of " original node 1 and 2 exits " comprising modification information by itself original node private key signature
It can contract.
Certainly, in this example, intelligent contract is modified to be also required to obtain the approval that other in alliance's chain originate node, other
Original node receives the modification intelligence contract by other original node private key signatures, and the node public key that application obtains in advance is tested
It demonstrate,proves other original node private key signatures and shows the original node that the modification intelligence contract does not confirm strictly if being verified
What itself sent, thus, analytic modification intelligence contract obtains block chain modification information, tests the block chain modification information
Card, the modification if confirmation block chain modification information, to the broadcast of the first block chain network by itself original node private key signature
Intelligent contract, as the block chain modification information appear affirmative vote, when knowing the original nodes of all other all to modification intelligence
After contract carries out private key signature, then show that all original nodes are recognized the block chain modification information, block chain modification
Information is legitimate, to broadcast the contract establishment message for modifying intelligent contract to the second block chain network.
Step 103, accounting nodes, which receive, updates the contract of intelligent contract and sets up message, and parsing updates intelligent contract and obtains the
Two block chain modification informations, and determine the corresponding change type of the second block chain modification information, if knowing, the second block chain is changed
