Description
Technical field
The present invention relates to the data revision field under license chain model, it is directed to solving due to block chain underlying protocol defect
Or error in data problem caused by the upper-layer service system failure, by means of the authority mechanism for permitting chain, there is provided for block chain
The controllable of data corrects function.
Background technology
Block chain is a kind of new distributed computing technology, by sequentially arranging the transaction blocking formed one by one, then by one
The block composition chain that individual order arrangement forms, each block include one from the height increased as numbering, and also a timestamp is used for
Record the packing time.
Block chain ownership is apparent, and the data write-in authority of account is controlled in itself by the user of grasp private key completely, book keeping operation section
Point is transaction sequence person, can not directly operate the data of user.Intelligent contract is also been developed on block chain, can be stored
Complicated data structure, and pass through individually designed each function operation data of the rules of competence.The variable data of intelligent contract
Eventually through some serializing operations, collect and pass through a tree structure again for the state of whole account, the state of whole accounts
A state root is generated, is stored in as card result is deposited in block head.So the characteristic that block chain can not be distorted, makees it
Good data storage medium when being cooperated for multi-party antagonism, and these data are typically all to be worth ownership registration, or
The related processing logic of value transaction.
Block chain is generally divided into publicly-owned chain and license chain, and publicly-owned chain refers to complete decentralization, without keeper, without standard
Enter the block chain of authority, the difference of data needs to solve by hard bifurcated on chain, and then crowd's reselections of different common recognitions are not
Same bifurcated.Such as geth-parity bifurcated events etc. caused by the cleaning of TheDAO events, ether mill State Tree.
License chain generally refers to node and the block chain of account access, runs real-life authentic commercial scene,
The even this kind of large-scale financial scenario such as bank.The typically exigent data accuracy of this kind of mechanism, it is impossible to which tolerance occurs one
Point point mistake.License chain is also generally considered to be polycentric block chain, there may be administrator right, can also design
Data modification rule in particular cases.
Permit initial stage of the chain technology also in development, first floor system is realized and traffic contract realize it is unavoidable occur expect not
The mistake arrived, cause data run and expected results inconsistent, corrected if not doing midway, follow-up business is implemented can be more tired
It is difficult.And these data revision demands beyong contemplation, at present typically using the scheme of hard bifurcated, it is necessary to development chain bottom generation again
Code, or started from scratch using clear chain, then the scheme that the data corrected are imported again, waste time and energy and increase O＆M portion
The difficulty of administration.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of data revision method based on license chain.
The purpose of the present invention is achieved through the following technical solutions：A kind of data revision method based on license chain, should
Method includes：
(1) the administrator right rule agreement for initiating effective " correcting data " class transaction is formulated, and is saved in license chain
Client.
(2) when running into data revision demand, related personnel makes decision data revision solution details in chain；
(3) meet the node of administrator right rule, according to data revision solution details, initiate " correcting data-locking "
Merchandise tx_lock, is comprising data：Account address list to be locked；
(4) node first verifies that administrator right rule after tx_lock transaction is received, and after being verified, execution " is ordered
Correction data-locking " transaction tx_lock, " unlocked " by the state of the account in account address list to be locked from acquiescence, by
Individual to be revised as " locked ", tx_lock runs succeeded；Node is when performing other non-" correcting data " class transaction, if held
The data for the account that write state is " locked " are needed during row, then the transaction performs failure, rollback transaction implementation procedure.
(5) meet the node of administrator right rule, according to data revision solution details, initiate " correcting data-renewal "
Merchandise tx_update, is comprising data：Locked account address, the index (Key) of variable, variable content (Value), repair
Change classification (" covering ", " deletion ").
(6) node first verifies that administrator right rule after tx_update transaction is received, and after being verified, reads
Account address in tx_update, the state of account is verified, if " locked ", is then verified, perform tx_update
In data revision content, it is Value that modification, which indexes the variant content of account for being Key, if classification is " covering ", if
Classification is " deletion ", then deletes variable of the index for Key.
(7) after all tx_updte transaction runs succeeded, required data revision operation had both been completed, has met keeper
The node of the rules of competence, according to data revision solution details, " correcting data-unblock " transaction tx_unlock is initiated, includes data
For：Treat unlocking account address list.
(8) node first verifies that administration authority rule after tx_unlock transaction is received, if checking is not by carrying out
Transaction reports an error.If being verified, the account address list in tx_unlock is read, and be by the status indication of these accounts
" unlocked ", tx_unlock runs succeeded.
Further, administrator right rule, can be an administrator address singly signed or more than one
The intelligent contract for address or the somewhat complex design of signing again.
The beneficial effects of the present invention are：The present invention has given up the data revision side of hard bifurcated and clear chain in current license chain
Case, by formulating administrator right rule, safely and efficiently merchandised by sending special " data revision ", to meet that data are ordered
Positive demand, and the granularity of account variable can be refine to, by means of the state tissue of account in itself and card method is deposited, smoothly
The target that the hard bifurcated of original need can just be reached is completed on ground, eliminates the trouble of exploitation again and O＆M deployment.
Embodiment
The present invention relates to a kind of data revision method based on license chain, this method includes herein below：
First, the administrator right rule agreement for initiating the transaction of " correcting data " class is formulated：
1：When formulating the agreement of license chain, it is necessary to formulate the keeper that can initiate effective " correcting data " class transaction
Rules of competence agreement, and it is saved in license chain client.The present invention does not limit the specific design of the rules of competence, can be a list
The administrator address of signature or the intelligent contract of a multi-signature address or somewhat complex design.
2：The agreement is write into license chain client code, chain starts from wound generation block, receives customer transaction and persistently goes out block.
When the 2nd, running into the situation for needing data revision, according to administrator right rule, initiate " correcting data-locking " and hand over
Easily：
1：When running into data revision demand, related personnel makes decision data revision solution details in chain.
2：Meet the node of administrator right rule, initiate " correcting data-locking " transaction tx_lock, be comprising data：
Account address list to be locked.
3rd, after node receives " correcting data-locking " transaction, all accounts of statement in locked transaction：
1：Node first verifies that administrator right rule after tx_lock transaction is received, if not by transaction report
Mistake, if continuing following operation if.
2：Account address list in node reading tx_lock, " unlocked " by the state of these accounts from acquiescence, by
Individual mark is locked ", tx_lock runs succeeded.
The node of " locked " is when performing other non-" correcting data " class transaction, if needing to write in implementation procedure
State is the data of the account of " locked ", then the transaction performs failure, rollback transaction implementation procedure.
4th, after account locks, according to administrator right rule, " correcting data-renewal " transaction is initiated：
1：After tx_lock transaction runs succeeded, according to administrator right rule, " correcting data-renewal " transaction tx_ is initiated
Update, it is comprising data：Account address, the index of variable are locked：Key, variable content：Value, classification, wherein class
Not optional " covering " and " deletion ".

Report an error, then continue following operation if " locked ".
3：Node is according to other data in tx_update, the account that modification index is Key if classification is " covering "
Variant content be Value, if classification is " deletion ", delete index for Key variable.Here with general transaction processing side
Formula is the same, and unserializing goes out the state of account first, reduces the content of each variable, simply bypassed account logic in itself or
Intelligent contract code, variable modification is directly carried out, is finished equivalent to transaction.Then carry out succeeding state serializing, deposit card
Deng operation.
6th, according to administrator right rule, " correcting data-unblock " transaction is initiated：
After all tx_updte transaction run succeeded, required data revision operation was both completed, had been weighed according to keeper
