As shown in Figure 1, the present invention provides a kind of commodity transaction information sharing methods based on block chain technology, including such asLower step:
Step S100, original seller's block group, buyer's block group, intermediate participant block group, information intermediate storage are builtBlock group and third party's block group, the user newly increased or information data generate new block according to classification, and new block andOriginal block forms block chain, by the way that original block to be divided into different block groups, can facilitate different user and dataManagement.
In the step s 100, newly-increased user generates the specific steps of new block are as follows:
Step S101, newly-increased user registration information in block catenary system, and reliable identity is carried out by identity cardVerifying.
Step S102, after completing authentication, block catenary system stores user information to new block, and according toNew block is divided in different block groups by user identity.
Step S103, after the registration is finished, block catenary system can provide one group of public and private key to each user, for pairPersonal information carries out selection encryption.
In step s 103, user can classify to personal information, and one kind can disclose owner, another kind of choosingSelecting property discloses, and is encrypted respectively with public key and private key, and public key publication is in block chain network, when other users access,System transfers public key automatically and accesses, and can only access the information of public key encryption, and private key is stored by user itself, only logicalIt crosses verifying or user gives the information that could access private key encryption, verification mode is selected and formulated by user oneself.
Step S104, newly-increased user and the credit bank of block catenary system authorization reach an agreement, and according in block chainThe ratio for participating in each side's common recognition carries out the exchange of ideal money and legal tender, participates in all nodes that common recognition participates in block chainIt with reaching common understanding per family, and can not distort, avoid the benefit damage of user, before transaction, user can change by legal tenderEquivalent ideal money is taken, and carries out the transaction of commodity with ideal money, it is also possible to withdraw deposit to ideal money.
Step S200, intelligent contract is written in block chain, when both parties initiate transaction request, generates transaction and refers toIt enables, while new transaction data being stored to newly-generated information intermediate storage block, each transaction data corresponds to onlyOne transaction id simultaneously adds timestamp, by setting timestamp, can be avoided unique transaction id and is tampered.
Step S300, in entire flow process, merchandise news and flowing information when each step flows store commodityIn to newly-generated information intermediate storage block, and generate the intermediate ID for adding timestamp.
In step s 200, when both parties initiate transaction request, generate trading instruction, block catenary system can be according to friendshipEasily instruction creation transaction data, and a unique commodity ID is created to tradable commodity, commodity ID can be number and letterCombination.And it is generated according to commodity transaction sequence.
When generating commodity ID, block catenary system can automatically generate an activation code according to commodity ID, and as activation conditionA new information intermediate storage block and new third party's block are generated in block chain.
Newly-generated information intermediate storage block and third party's block is all provided with using corresponding commodity ID as store instructionA difference suffix is set, such as a store instruction is XXXXXX.1, another store instruction is XXXXXX.2, for differentStorage content carries out classification storage, meanwhile, it is capable to store each information of corresponding goods fast and accurately into correct block.
All Activity data and merchandise news, flowing information under commodity ID pass through store instruction and store to correspondenceInformation intermediate storage block in, all intermediate ID and unique transaction id under commodity ID pass through store instruction store toIn corresponding third party's block.
In step s 200, when both parties initiate transaction request, and conclude the transaction agreement when, block catenary system is to transactionBoth sides send trade confirmation, if both parties confirm, the virtual coin of the amount under buyer's account is transferred to by systemSeller's account, and the flowing that seller sends commodity and commodity is supervised, meanwhile, Transaction Information is sent to block chain network, ifBoth parties are without all confirmations, then cancellation of trading.
When concluding the transaction, block catenary system will create and disposes an order contract both parties, and order contract includesMerchandise news, commodity price, buyer address and logistics information, inspection information etc., order contract is being flowed with chains of commodity flowDuring contract supplement and perfect carried out by seller, intermediate participant, wherein merchandise news, commodity price, buyer address etc.It is filled in by seller, logistics information, inspection information etc. are filled in by each intermediate participant, by order contract, are conducive to transactionIt is supervised and is authenticated.
Block catenary system is each original user and the distribution one number of segment word mark that Adds User, for corresponding to unique useFamily identity, the intermediate ID that commodity generate when by the flowing of intermediate participant can add a prefix and a suffix automatically, precedingSewing is that previous intermediate participant or the digital of seller identify, and suffix is the number of intermediate participant or buyer that commodity will flow toWord mark, as pass through during chains of commodity flow seller, each intermediate participant, buyer number mark be respectively 100000,100001,100002,100003, commodity original intermediate ID for generating when by the flowing of intermediate participant be 200001,200002, the then intermediate ID ultimately generated are 100000.200001.100002 and 100001.200002.100003, are passed throughPrefix and suffix are added on intermediate ID, can be facilitated and the flowing of commodity be traced to the source and flowed to inquiry, thus handing overWhen easy or commodity problem, it is quickly found out commodity or problem appearance point, is conducive to transaction issues of calling to account or solve.
Step S400, both parties are initiating transaction request, and when generating trading instruction, can generate one new the simultaneouslyTripartite's block and third party's block identifying code, third party's block identifying code is published to automatically in block chain network, in addition, commodityThe unique transaction id generated in process of exchange and the intermediate ID generated in flow process are stored in third party's block.
In step S400, third party's block identifying code can be bound together with commodity ID, both parties, intermediate participantAnd regulator can obtain the corresponding third party's block identifying code of tradable commodity by commodity ID or out of block chain network,By third party's block identifying code, the content of corresponding third party's block storage is inquired, and passes through storage in third party's blockMerchandise news, transaction data and the flowing information of unique transaction id and the storage of centre ID query information intermediate storage block memory.
By the way that third party's block is arranged, so that both parties, intermediate participant and regulator can pass through commodity IDQuickly essential information, Transaction Information and the flowing information of inquiry commodity, so that each list of the commodity in process of exchangeSide is not at island state, so that commodity transaction information is shared more abundant, and can be avoided folk prescription on chain transaction and distorts friendshipEasy information is conducive to the fidelity of guaranteeing the quality of commodity, meanwhile, when supervising to transaction, regulator can be facilitated numerous many and diverseCommodity transaction information in, quickly find required Transaction Information, be conducive to improve transaction transparency, facilitate supervision.
The third party's block identifying code and Transaction Information being sent in block chain network can be stored to raw informationIn several nodes in memory block group, and add timestamp, it is each with per family can by timestamp in the information between storeRequired Transaction Information or third party's block identifying code are found in block.
Data are handled by Hash when storing write-in, and commodity, in flow process, merchandise news is by HashHash value after reason remains unchanged, if hash value changes, may determine that commodity go wrong, and Hash processing is random lengthInput be transformed into the output of regular length by hashing algorithm, this conversion is that a kind of compression maps, it is, hashed valueSpace, which is generally much less than the space inputted, can either reduce the occupied space of data, and can be right by handling data HashData are encrypted, and data is avoided to be tampered, simultaneously as the data of identical hash value, even if filename changes, content is also agreedFixed identical, therefore, commodity, if the hash value of description merchandise news changes, may determine that commodity go out in flow processShow problem, is conducive to the inspection of commodity.
