The account roles can be divided into multiple roles of generation, transportation, purchase, processing, sales and the like according to the different operation ranges of enterprises, and the same blockchain account can have multiple account roles, for example: the environmental protection treatment enterprise can process the waste material, and sell the product that obtains after processing according to the waste material, because of its corresponding blockchain account can possess simultaneously and process and sell two kinds of roles. The security verification of the waste procurement information may be to verify whether the waste procurement information meets the security rules of the public chain.
Further, in order to ensure the security of the public chain, before step S10 of this embodiment, the method may further include:
Receiving account registration information sent by a user, and sending the account registration information to a supervisor so that the supervisor carries out information auditing on the account registration information; when the information verification passes, determining an account role according to the account registration information, and generating an account public key and an account private key according to the account registration information through a preset key generation algorithm; and registering a blockchain account for the user in a public chain according to the account public key, the account private key, the account registration information and the account role, and feeding back the account public key and the account private key to the user.
It should be noted that, the account registration information may include data such as an establishment time of an enterprise, an enterprise operation range, an enterprise operation status, a business license scanning piece, and the user may be an enterprise to be added to a public chain. The supervision party can be a supervision department, and the supervision department can be provided with supervision nodes in public chains, and the supervision nodes can be used for information auditing and information supervision. The preset key generation algorithm may be set according to actual needs, which is not limited in this embodiment. Determining the account role according to the account registration information may be determining a participation link of the enterprise in the waste treatment process according to an enterprise operation scope in the account registration information, so as to determine the account role, for example: if the enterprise operation range is transportation, determining the corresponding account role as transportation; if the enterprise operation range is environmental protection management, determining the corresponding account role as processing and selling.
It can be understood that before the blockchain account is registered in the public chain for the user, the account registration information of the user is sent to the supervision party for verification, and after the verification is passed, the blockchain account is created for the user, so that the accounts in the public chain are all verified safe accounts, and the safety of the public chain can be ensured.
Further, in order to improve the security, step S10 of this embodiment may include:
When receiving the waste purchasing information, carrying out data analysis on the waste purchasing information to obtain purchasing signature information, account identification and purchasing information; acquiring a corresponding blockchain account and an account public key of the blockchain account according to the account identifier, and decrypting the purchase signature information according to the account public key to acquire decrypted purchase information; when the purchase information is consistent with the decrypted purchase information, acquiring an account role corresponding to the blockchain account; and if the account role is the preset purchase information release type, judging that the waste purchase information passes the security verification.
The waste purchase information may include purchase signature information, account identification, and purchase information, where the purchase signature information may be data obtained by digitally signing the purchase information with an own account private key by a party sending the waste purchase information, the account identification may be an identification for declaring a blockchain account sending the waste purchase information, and the purchase information may include information such as a waste producer identification, a waste processor identification, a waste quantity, an amount, and a waste transport address, where the waste producer identification is an account identification of a blockchain account of an enterprise that produces waste, and the waste processor identification is an account identification of a blockchain account of an enterprise that processes waste.
In actual use, the block chain node in the public chain may store an account information table of all accounts, where the account information table may store account information of all registered accounts, where the account information may include information such as an enterprise name, an enterprise operating range, an account identifier, an account public key, and an account role. The obtaining the corresponding blockchain account and the account public key of the blockchain account according to the account identifier may be searching corresponding account information in an account information table according to the account identifier, and determining the blockchain account and the corresponding account public key corresponding to the account identifier according to the account information.
It can be understood that the account public key and the account private key are corresponding, after the data are encrypted through the account private key, the encrypted data can be decrypted by utilizing the corresponding account public key to obtain the original data, therefore, after the account public key is obtained, the purchasing signature information can be decrypted according to the account public key, the decrypted purchasing information obtained by decryption is compared with the purchasing information, when the two are consistent, the signature can be determined to be valid, the data can be determined to be safe data, then whether the blockchain account has the corresponding operation authority can be verified, the account role of the blockchain account can be obtained, whether the account role is the preset purchasing information release type can be determined, when the account role is the preset purchasing information release type, the blockchain account can be determined to have the corresponding authority, and the safety verification can be determined to pass. Since the purchase of the waste generally involves only two parties, namely, a waste producer for producing the waste and a waste processor for processing the waste, the preset purchase information distribution type can be produced or processed, that is, when the account role of the blockchain account is production or processing, the passing of the security verification can be determined.
Step S20: and if the safety verification is passed, determining a waste treatment party according to the waste purchasing information, and constructing a waste purchasing contract according to the waste purchasing information.
When the safety verification is passed, determining that the waste processor can search the corresponding blockchain account according to the waste processor identifier recorded in the waste purchase information according to the waste purchase information, and taking the enterprise corresponding to the searched blockchain account as the waste processor. The waste procurement contract may include information on a waste producer public key, a waste processor public key, a quantity of waste, an amount of money, a waste shipping address, and the like. The construction of the waste purchase contract according to the waste purchase information may be to acquire a waste processor identifier, a waste producer identifier, a waste quantity, an amount, and a waste transport address recorded in the waste purchase information, search a waste processor public key in an account information table according to the waste processor identifier, search a waste producer public key in the account information table according to the waste producer identifier, and construct the waste purchase contract according to the waste processor public key, the waste producer public key, the waste quantity, the amount, and the waste transport address.
It will be appreciated that the blockchain-based waste handling device may also store the waste procurement contracts and the waste procurement information after the construction of the waste procurement contracts, and broadcast in the public chain, causing other blockchain nodes in the public chain to be stored as well.
Step S30: pushing the waste purchasing contract to the waste treating party, and receiving waste transportation information fed back by the waste treating party.
It will be appreciated that the scrap procurement contract may be pushed to the scrap handler after the scrap procurement is completed to cause the scrap handler to determine how to transport the scrap for subsequent processing. The waste shipping information may include information such as waste transporter account identification, waste shipping address, waste pick-up address, waste shipping time, quantity of waste, etc.
In actual use, the information such as the enterprise name, the enterprise operating range, the account identification and the like of the blockchain accounts with all account roles in the blockchain being transported can be obtained, and the information and the waste purchasing contract are pushed to the waste processor together, so that the corresponding waste transporter can be conveniently selected for waste transportation, and the waste transportation information is fed back.
Step S40: and sending the waste transportation information to a waste transportation party so that the waste transportation party can transport the waste to the waste treatment party for treatment.
It will be appreciated that after receiving the waste transport information fed back by the waste processor, the waste transport information may be sent to the waste processor to cause the waste processor to transport the waste to the waste processor for processing.
In practical use, the waste transportation information is sent to the waste transportation party, so that the waste transportation party can transport the waste to the waste treatment party for treatment, namely, the waste transportation party identifier, the waste transportation time, the waste receiving address and the waste signing address recorded in the waste transportation information are firstly obtained, the corresponding account information is searched in the account information table according to the waste transportation party identifier, and the waste transportation information is sent to the waste transportation party according to the account information, so that the waste transportation party receives the waste at the waste receiving address according to the waste transportation time and transports the waste to the waste signing address, and the waste treatment party signs the waste at the waste signing address for treatment. When the amount of waste is large, the waste transportation may be carried out by a plurality of different waste transportation parties, and when a plurality of waste transportation parties exist, a waste transportation party identification list may be recorded in the waste transportation information, and the waste transportation party identification list may contain account identifications of a plurality of waste transportation parties.
In practical use, the waste transportation contract may be constructed according to the waste transportation information, and stored in a public chain, where the waste transportation contract may include information such as a waste transportation party public key, a waste disposal party public key (or a waste transportation party public key list), a transportation amount, and the like.
It will be appreciated that after the waste transport party transports the waste to the waste disposal party, the waste disposal party's receipt of the waste may also be obtained and stored in the public chain.
Step S50: and acquiring waste treatment flow information of the waste treatment party, constructing waste treatment data according to the waste purchasing contract, the waste transportation information and the waste treatment flow information, and storing the waste treatment data into a public chain.
It should be noted that, after receiving the waste, the waste processor triggers an internal production process, and in the production process, each production processing node generates result data, and the waste process information may be the result data generated in all the production processing links.
It will be appreciated that for ease of administration, data is required to record the process of waste disposal, and therefore, waste disposal data may be constructed from waste procurement contracts, waste transportation information, waste disposal flow information and stored in public chains. The storing of the waste processing data to the public chain may be that the waste processing device based on the blockchain digitally signs the generated waste processing data with its own node key, and broadcasts the waste processing signature information obtained by the digital signature and the waste processing data together to each blockchain node in the public chain, and each blockchain node may perform security verification on the waste processing signature information and the waste processing data according to the node public key of the waste processing device based on the blockchain after receiving the waste processing signature information and the waste processing data, and store the waste processing data when the security verification passes.
Further, in order to reduce the storage difficulty and the storage cost, step S50 of this embodiment may include:
Acquiring waste treatment flow information stored on a private chain of the waste treatment party, and encrypting the waste treatment flow information to obtain waste treatment characteristic data; and constructing waste treatment data according to the waste purchase contract, the waste transportation information and the waste treatment characteristic data, and storing the waste treatment data into a public chain.
It should be noted that, the internal production process of the waste disposal party may be very complex, so that the generated waste disposal process information may have very large data volume, if the waste disposal process information is integrally stored to the public chain, the efficiency is low, and the required storage space is very large, the storage difficulty is high, and the storage cost is high, therefore, after the waste disposal process information is obtained, the waste disposal process information is encrypted by using the preset encryption algorithm to obtain the waste disposal characteristic data, and then the waste disposal data is constructed according to the waste purchasing contract, the waste transportation information and the waste disposal characteristic data, and the waste disposal data is stored to the public chain, thereby saving a large amount of storage space, reducing the storage difficulty and the storage cost. The preset encryption algorithm may be SHA256 algorithm, or may be other algorithms, and the waste processing feature data may be a hash value obtained by encrypting by the preset encryption algorithm. And when corresponding waste treatment flow information is required to be acquired later, the corresponding waste treatment flow information can be acquired from the private chain of the waste treatment party, the authenticity of the waste treatment flow information on the private chain is identified through the waste treatment characteristic data recorded on the public chain, and the safety of the data can still be ensured on the premise of reducing the storage difficulty and saving the storage space.
The embodiment performs security verification on the waste purchasing information when receiving the waste purchasing information; if the safety verification is passed, determining a waste treatment party according to the waste purchasing information, and constructing a waste purchasing contract according to the waste purchasing information; pushing the waste purchasing contract to a waste treatment party and receiving waste transportation information fed back by the waste treatment party; sending the waste transportation information to a waste transportation party so that the waste transportation party transports the waste to a waste treatment party for treatment; and acquiring waste treatment flow information of a waste treatment party, constructing waste treatment data according to the waste purchasing contract, the waste transportation information and the waste treatment flow information, and storing the waste treatment data into a public chain. Because the whole processing flow is carried out in a public chain established by a supervision party, the data is difficult to tamper, the disclosure and transparency of the waste processing process can be ensured, and the supervision is facilitated.
Referring to fig. 3, fig. 3 is a flow chart of a second embodiment of a blockchain-based waste treatment method according to the present invention.
