Embodiment 1
As shown in Figure 1, a kind of monitoring and managing method of block chain, comprising the following steps:
When a transaction occurs, known together by the supervisory node and other common recognition nodes to the transaction, the prison
Pipe node is equipped with configurablely and agrees with ballot weight and the opposition ballot weight not less than a threshold value；
When the supervisory node opposes the transaction based on the result for auditing the transaction, then the transaction does not pass through altogether
Know；
When the supervisory node is based on the result and agrees with the transaction, if described agree with ballot weight to be equal to zero,
When then agreeing with the number of nodes of the transaction to meet common recognition algorithm in other described common recognition nodes, the transaction passes through common recognition；
If described agree with ballot weight to be greater than zero, (participated in altogether in the supervisory node and other described common recognition nodes
The node of knowledge) in agree with the transaction number of nodes meet common recognition algorithm when, the transaction passes through common recognition；
The transaction auditing include: Account Review, transaction content safety and privacy audit, transaction content legitimacy audit,
One of transaction content compliance audit is a variety of.
It should be understood that the threshold value in the above method is arranged according to common recognition algorithm, such as provided in common recognition algorithm
The opinion of half is common recognition as a result, then threshold value should be set as 50% or 0.5, the opposition ballot weight of supervisory node not less than 50% or
0.5.It is not meet supervision to be filled into make supervisory node have right of veto by one vote that the purpose for opposing ballot weight, which is arranged,
The transaction of standard.
In the above method, when supervisory node is voted for, it should agree with ballot weight according to supervisory node and continue
It knows together.If the ballot weight of agreeing with of supervisory node is zero, then it represents that supervisory node was launched agrees with ballot invalid, then total
Know result and depends on the quantity that other common recognition nodes agree with the transaction.If described agree with ballot weight to be greater than zero, then it represents that prison
What pipe node was launched agrees with ballot effectively, then common recognition result depends on supervisory node and other know together what nodes were voted for
Quantity.
For example: 5 nodes, 4 ordinary nodes, 1 supervisory node are shared in block chain, common recognition mechanism is plurality
It then votes through, the weight total value of yeas and nays is 100%.When the ballot weight of supervisory node is arranged are as follows: oppose
Ballot weight 60% agrees with ballot weight 0, knows together and does not pass through if supervisory node is voted against；If supervisory node is voted for,
The ballot situation for then needing to count other nodes is known together if having 3 to vote in other nodes and is passed through.When supervisory node
Ballot weight setting are as follows: oppose ballot weight 60%, agree with ballot weight 20%, if supervisory node is voted for, counting
Including needing to calculate the voting results of supervisory node when situation of voting, if there is 1 to vote in other nodes, know together obstructed
It crosses, if there is 2 to vote in other nodes, common recognition passes through.
In method disclosed by the invention, supervisory node has carried out comprehensively transaction from the node for initiating transaction to transaction content
Audit.Wherein whether safety and privacy audit are to audit in the information that transaction includes with to block chain information safety tool
There are the programs such as wooden horse, the virus of menace, if the sensitive information with leakage privacy.Compliance audit is to judge to trade
Whether content closes rule, for example the type traded is loan transaction, then interest rate setting is no more than the upper limit as defined in Central Bank, for example borrows or lends money
The interest rate of both sides' agreement is no more than Annual Percentage Rate 36%；Whether for the money transfer transactions of transaction, then being defined according to transaction limit is big
Volume transaction or suspicious transaction have wholesale or suspicious transaction then to be recorded and reported etc. and do not meet information as defined in industry.It is legal
Property audit be to judge whether Transaction Information illegal.
Common recognition algorithm described in the above method may include: POW, POS/DPOS, BFT/Tendermint, PBFT,
DAG etc..
Block chain monitoring and managing method disclosed in the present embodiment is when trading generation, by supervisory node to the node for initiating transaction

As shown in figure 3, S1, create an account node audit, node request create an account and submit data information, supervisory node
The data information is audited, supervisory node disagrees node and creates an account not by if if audit, if audit, which passes through, supervises section
Point sends public and private key and block chain address to node, and wherein block chain address is the private key signature that supervisory node utilizes its own
Encrypted block chain address.
It should be noted that step S1 interior joint can create an account submission data information by supervisory node client.
Data information includes node owner's data information and nodal information two parts.The data information packet if node owner is individual
Include: personally identifiable information, certificate photograph or scanned copy, personal reference situation etc. are able to reflect personal identification, status, credit situation
Information.Data information includes: enterprise name, business license, corporate message and business standing if node owner is enterprise
Etc. the information for being able to reflect enterprise present situation, credit situation and status of a legal person, status, credit situation.Personal, company information and reality
Border is not inconsistent, have it is illegal break one's promise situation when then audit and do not pass through.
Public and private key can generate a pair of public and private key using elliptic curve digital signature algorithm (ECDSA) in step S1, wherein
It selects secp256k1 curve to go out public key by ECDSA algorithmic derivation using private key, then passes through Keccak-256 uni-directional hash
Function derives block chain address.
Block chain address is sent to supervisory node by S2, the Account Review for starting the initial stage, node, and supervisory node utilizes
Public key decrypts block chain address sign test, and node can carry out next step operation by Account Review if successful decryption, if solution
Close unsuccessful, supervisory node does not allow node to carry out next step operation.
It should be noted that block chain address just passes through the private key encryption of supervisory node itself when step S1 is generated, because
This in step s 2 in order to verify node block chain address authenticity, the same public key decryptions for using supervisory node itself,
The authenticity of node identities can be verified if successful decryption.
The block chain address of its own is sent to supervisory node when node initiates transaction by S3, common recognition audit.Supervision section
Point receives after transaction and remaining common recognition node knows together to transaction, and wherein supervisory node votes weight are as follows: agrees with
Ticket weight is 0%, and negative vote weight is 60%.
Transaction auditing includes: Account Review, transaction content safety and privacy audit, the audit of transaction content legitimacy, transaction
The audit of content compliance.Account Review includes: the audit of node account identity and the audit of credit situation.It was audited in node identities
Cheng Zhong, supervisory node search the data information of node by block chain address, meanwhile, supervisory node examines the letter of node owner
With situation, if supervisory node searches, the supervisory node bad less than the credit record of the data information of node or node
It votes against, since the weight accounting of supervisory node is more than half so common recognition result is to reject.If supervisory node is in authenticity and letter
It is not found the problem, then voted for in the audit of situation, remaining common recognition node is known together according to common recognition mechanism, common recognition knot
Fruit depends on the number for the node voted in remaining common recognition node.
It should be noted that supervisory node has what be can configure to vote weight during common recognition.To node
When auditing authenticity and credit situation, it can make to supervise according to the negative vote weight of the criterion adjustment supervisory node of common recognition mechanism
Pipe node has right of veto by one vote.
S4, cochain storage audit, comprising:
The node for participating in the common recognition, which votes to it by the private key of its own in common recognition, signs；
Whether the signature for the block that each common recognition node verification is reached common understanding is authentic and valid；
Node on the block catenary system passes through the section of the participation common recognition before the deposit transaction data base that will trade
The public key of point carries out signature verification to ballot, to verify the authenticity of transaction.
Verification audit of the successfully transaction before cochain it should be noted that step S4 is used to know together.It is participated in after common recognition
The node of common recognition signs to ballot, and the synchronous block of other nodes on block chain is only to need to utilize participation common recognition node
Public key sign test can check the authenticity of transaction.
S5, Transaction Inquiries supervision, when there is node to initiate Transaction Inquiries request, supervisory node still needs to carry out inquiry request
Supervision, monitoring and managing method is similar with the monitoring and managing method of transaction, only changes the object of supervision into inquiry request from transaction, transaction is looked into
It is careful to ask the Account Review, inquiry content auditing, common recognition supervised may include: when creating an account node audit, initiation inquiry request
Plurality of step in core, data loading supervision.
The present embodiment be described in detail so that node is without the new node of registered block chain as an example disclosed by the invention one
The specific steps of the monitoring and managing method of kind block chain.For node is the existing node run, if the data of node is believed
When change, which has occurred, in breath causes data information cannot be by audit in step S1 about data information, then supervisory node is to block
Each other nodes on chain issue the proposal for removing the node, and other each node shield nodes are not traded with the node.
The present embodiment is realized by establishing supervisory node in block chain to be sent out in the node and node on block chain
The supervision of raw transaction, overcoming supervision existing in the prior art has the problem of missing, guarantees the safety of block catenary system information.
