Specific embodiment
As shown in Figure 1, for a kind of data deposit and search system based on block chain, comprising:
Application layer API (Application Programming Interface, application programming interface) module, should
Module is for response application layer to the calling of block chain public affairs chain intelligence contract；The information that management, screening application layer are sent, in block
The function of increase and inquiry is realized on chain；And invalid information is returned to the account abnormal operation of access block chain.
User, role, authority management module, the module are used for user, role and the permission of access block chain according to finger
Fixed algorithm carries out the verifying of user, role, and carries out validation verification to the permission of each user；Asynchronous message is provided simultaneously
User is pushed in application layer API module the relevant operation of account information, real-time update account information by Push Service.
Database module, the module are used for the content of timing synchronization update database and block chain；The module is for timing
The content of incremental update database and block chain；And pass through Fen Ku, the work for dividing the technologies such as table, index to improve database.
Internal storage data library module, in order to cope with high-throughput and big concurrent status, which is placed on database data
Directly operation is in memory to improve efficiency；The module is used for the content of timed increase more new database and block chain.
As shown in Fig. 2, for the deployment process of data deposit and search system based on block chain, comprising:
1) DAPP (Decentralized Application, decentralization application, be also Distributed Application) is opened, matched
Set document definition IP address and port numbers；
2) authentication verification code whether there is, and such as exist, then configuration file enters DAPP user interface；
3) as authentication code is not present, then DAPP port numbers, deployment path, systematic name are obtained, initiates registration request, verifying
Whether register；
4) DAPP list is written, generates authentication code, configuration file is written to, into DAPP user interface.
It as shown in figures 1 and 3, is a kind of data store method based on block chain of the invention, the method packet of the deposit
Include following steps:
1) GAS is obtained from request header:
User is entered by DAPP (Decentralized Application, decentralization application, be also Distributed Application)
Mouthful, information is inputted to application layer API module, application programming interface module enters information into user, role, rights management
Module is verified, and user, role, authority management module interact information and internal storage data library module, completes permission point
Match, call the method for obtaining GAS, obtains GAS.
GAS is the fuel that program executes, and the code of an EVM (ether mill virtual machine) is realized on the block chain of ether mill
Running environment, when executing write operation on chain, the full node of each of network can carry out identical calculating and store identical
Value, the consumption of this execution be it is expensive, carried out in order to which the operation for promoting everybody that will carry out under chain is not put on chain,
It also for reward miner, therefore in one write operation of every execution on chain, requires to pay certain expense, is single with GAS
Position counts, and the order that can each execute on chain is provided with the GAS value of a consumption,
2) user carries GAS and initiates request, prepares timestamp, public key, cochain content being stored in block chain；
3) the user right version is read from memory database, if permission version is inconsistent, then returns to and obtained from request header
GAS is taken, if permission version is consistent, then calls intelligent contract, upper segment block, if intelligent contract respective request, executes a transaction,
Transaction Information and remarks content, are written new block by upper segment block success, then terminate contract, and segment block as above fails, Fail Transaction,
GAS burns down intelligent contract and is automatically stopped.
It as shown in Figure 1 and Figure 4, is a kind of data search method based on block chain, the method for the search includes following step
It is rapid:
1) user is by DAPP entrance, by application layer API module input information, information and internal storage data library module into
Row interaction obtains user, role, authority management module verifying and distribution permission.
2) user inputs search key and the interaction of internal storage data library module, especially by existing artificial AI engine and
Combination algorithm is interacted with internal storage data library module.
3) internal storage data library module returns to search result and search result is returned to DAPP if searching for successfully, if not searching
Suo Chenggong then continues to say that keyword combination algorithm is interacted with internal storage data library module.
4) current search events are recorded using the data store method based on block chain by cochain, that is, is stored in block chain link
Point cluster.
The present invention is combined by the database technology of centralization and the block chain technology of decentralization, promotes block chain number
According to the efficiency of deposit and search.
