Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
The BigBang Core is a block chain application system which divides the main chain data and the application data and stores the system block data by a tree-shaped block structure of 'safe main chain + multiple application branched chains'. The EDPoS + CPoW form is used as a consensus mechanism generated by system blocks, the system is safe and stable, the transaction processing speed is high, and the requirements of all application scenes of the Internet of things can be almost met. The BigBang Core decentralized e-commerce template is suitable for decentralized point-to-point e-commerce transactions. The method can drive both sides of the transaction to finish the transaction in good faith without a third party arbitration mechanism by a mortgage transaction mode. In this embodiment, a decentralized blockchain transaction platform of interplanetary file System (IPFS) data is created through the BigBang Core decentralized blockchain e-commerce template, and a buyer and a seller can perform point-to-point transaction on the blockchain platform.
FIG. 1 is a flow chart of an embodiment of the IPFS data transaction method based on the BigBang Core block chaining E-commerce template. Referring to fig. 1, the application of the present embodiment to a decentralized block chain platform may include the following steps:
s101, obtaining supply and demand information of an IPFS storage space;
in this embodiment, supply and demand information of the IPFS storage space may be acquired. The supply and demand information includes demand information of the IPFS storage space and supply information of the IPFS storage space, specifically, bandwidth, unit price, capacity, and the like of the demanded or supplied storage space.
In this embodiment, the demand information of the IPFS storage space issued by the space demand party and the supply information of the IPFS storage space issued by the space supply party are acquired, so that the space supply and demand party determines whether to establish a transaction by browsing the demand information of the IPFS storage space and the supply information of the IPFS storage space.
S102, after receiving a transaction instruction based on the target supply and demand information, establishing a transaction link related to a space demand party and a space supply party so that the space demand party sends storage data to the space supply party for storage;
if the space demand party or the space supplier determines the target supply and demand information meeting the requirement of the space demand party or the space supplier by browsing the supply and demand information of the IPFS, a transaction instruction based on the target supply and demand information can be established.
In this embodiment, after receiving the transaction instruction based on the target supply and demand information, a transaction link between the space demanding party and the space supplying party may be established.
The transaction link may be established as follows: acquiring a transaction instruction initiating address, tracing a response address in the target supply and demand information on a block chain platform, and establishing a transaction link based on the initiating address and the response address.
Specifically, if a transaction instruction based on target supply and demand information is initiated by a space demander, the initiation address of the space demander can be acquired, information tracing is performed on a block chain platform, and a response address corresponding to the space demander in the target supply and demand information is determined, then a transaction link can be established according to the initiation address and the response address, so that the space demander sends storage data to the space demander for storage through the transaction link. If the transaction instruction based on the target supply and demand information is initiated by the space supplier, the initiating address of the space supplier is obtained, and the response address of the space demand supplier is traced on the block chain platform to establish the transaction link.
S103, carrying out storage challenge to a space supplier;
in this embodiment, in order to verify whether the space supplier stores the storage data, the storage challenge may be periodically or aperiodically issued to the space supplier.
Specifically, in this embodiment, a challenge instruction sent by the space demander periodically or aperiodically may be acquired, or a challenge instruction may be automatically generated periodically or aperiodically, and then a storage challenge may be performed to the space supplier according to the challenge instruction.
S104, verifying whether the storage data can be accessed on the storage address for the storage address responding to the storage challenge feedback by the access space supplier;
the space supplier feeds back the storage certification after receiving the challenge, if the challenge instruction is initiated by the space demander, the space supplier can feed back the storage certification to the space demander, and the space demander sends the storage certification to the block chain platform, and if the challenge instruction is initiated by the block chain platform, the space supplier can feed back the storage certification to the block chain platform.
Generally, common forms of proof are storage proof and space-time proof, however, the implementation of the copy proof and space-time proof is complicated, and in order to implement the space-time proof and the copy proof, a very large base library needs to be implemented, so that the IPFS storage profit proof is not only complicated in process, but also causes waste of storage space.
In this embodiment, the storage certification is a storage address for storing data, and the access space provider verifies whether the storage data can be accessed at the storage address for responding to the storage challenge feedback, and if the storage data can be accessed at the storage address, it indicates that the space provider has indeed performed storage according to an agreement, and does not track how the storage data is specifically stored, and does not need to occupy time and space to construct a basic library, so that the certification process is simple and fast.
S105, if yes, transferring the corresponding installment reward money in the account of the space demand party to the account of the space supply party according to a preset service rule;
if the storage data can be accessed on the storage address, the space supplier really stores the data according to the agreement, and the corresponding installment reward money in the account of the space supplier is transferred to the account of the space supplier according to the preset service rule.
Specifically, the service rule may be negotiated with the space supplier or the space demander before initiating the transaction instruction, or may be a service rule established in the blockchain platform, which is not limited in this embodiment. For example, the service rules may be set up in the following mode: the space supplier can take the installment reward money once every time the challenge succeeds, and the space supplier can take the reward money completely after reaching a certain height (for example, the space supplier completes ten challenges). The transaction parties can set the height to be high, and only if the space provider provides services truthfully, the reward money can be finally sent to the service provider. In addition, when both trading parties contract trading rules, the mode of 'quota x loyalty service coefficient' and the like is used for the installment reward amount, the longer the service time is, the higher the installment reward amount is, and otherwise, if the challenge fails, the higher the loss of the space supplier is.
Further, after the transaction of the space supplier and the space demander is expired, the space supplier or the space demander can initiate the transaction again, so that the space supplier can continue to store the storage data of the space demander and can obtain the corresponding reward.
The IPFS data transaction method based on the BigBang Core block chain E-commerce template is applied to a decentralized block chain platform, can obtain supply and demand information of an IPFS storage space of an interplanetary file system, receives and establishes transaction information when space supply and demand parties determine that storage space transaction needs to be carried out, generates a transaction link, and sends storage data to a space supplier through the transaction link by a space demander, and the space supplier stores the storage data. In the process of storage, a challenge is initiated to the space supplier, and the space supplier is accessed to a storage address responding to the storage challenge, and if the storage data can be accessed to the storage address, the challenge is successful. The technical scheme of the invention does not limit the type of the storage content, has wide application range and clear supply and demand relation, can prove the storage benefit of the IPFS on the premise of not using complicated space-time certification and replication certification, does not need to occupy time and space to construct a basic library, and has simple and rapid proving process.
Further, the present embodiment may further include the following steps: if the storage data is not accessible at the storage address, the space provider is penalized according to the service rule.
Specifically, if the storage data is not accessed on the storage address, which indicates that the space supplier does not faithfully store the storage data, the space supplier may be punished in such a way that the space supplier and the space demander can make a contract in advance, for example, the space supplier cannot take the remaining regular bonus or replace other space suppliers.
