Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an implementation environment of a garbage collection method based on a blockchain according to an embodiment of the present disclosure, and referring to fig. 1, the implementation environment may include a plurality of computer devices, where the plurality of computer devices may be a plurality of node devices in a blockchain system, and any one node device in the blockchain system may perform one or more steps in the garbage collection method based on a blockchain according to an embodiment of the present disclosure. The plurality of computer devices may be a plurality of node devices belonging to the same organization, or may be a plurality of node devices belonging to different organizations. For example, the plurality of computer devices may all belong to a garbage disposal facility, each department in the garbage disposal facility corresponds to at least one computer device therein, or at least one computer device in the plurality of computer devices is a user device, at least one computer device belongs to the garbage disposal facility, at least one computer device belongs to the environmental regulatory agency, and of course, there may also be at least one computer device belonging to other facilities, for example, other social regulatory agencies, and the like.
The plurality of computer devices may be servers or terminals, which is not specifically limited in this embodiment of the present application.
In order to facilitate understanding of the technical processes of the embodiments of the present application, some terms referred to in the embodiments of the present application are explained below:
block chain (Block chain): the method is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The blockchain is essentially a decentralized database, which is a string of data blocks associated by cryptography, each data block containing information about a network transaction for verifying the validity (anti-counterfeiting) of the information and generating the next block, each block containing a timestamp and a link to the previous block. In a narrow sense, a blockchain is a distributed ledger of data blocks assembled in a sequential manner into a chain data structure in chronological order and cryptographically secured as non-falsifiable and non-forgeable, i.e. the data in the blockchain will be irreversible once recorded.
Consensus mechanism (Consensus mechanism): the block chain system is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes. In the block chain system, the verification and confirmation of the transaction can be completed in a short time through the voting of special nodes, and if a plurality of nodes with irrelevant benefits can achieve consensus on a transaction, all the nodes in the system can also achieve consensus on the transaction.
Smart contract (Smart contract): is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Each node in the blockchain system can automatically execute a contract program according to a specific condition, can operate data stored in the chain, and is an important way for a user to interact with the blockchain and realize business logic by using the blockchain. The goal of smart contracts is to provide a secure method over traditional contracts and to reduce other transaction costs associated with the contracts, which allows for trusted transactions that are traceable and irreversible without third parties.
Public Key (Public Key) and Private Key (Private Key): is a key pair (i.e., a public key and a private key) obtained by an algorithm, the public key being a public part of the key pair, and the private key being a non-public part. Public keys are typically used to encrypt data, verify digital signatures, and the like. By means of this algorithm it is ensured that the resulting key pair is unique, and that when using this key pair, if one of the keys is used to encrypt a piece of data, the other key must be used to decrypt it, e.g. if the data is encrypted with the public key, the private key must be used to decrypt it, and if the data is encrypted with the private key, the public key must be used to decrypt it, otherwise the decryption will not succeed.
Fig. 2 is a flowchart of a garbage collection method based on a blockchain according to an embodiment of the present disclosure, where the garbage collection method based on a blockchain may be applied to any node device in the blockchain system, and referring to fig. 2, the embodiment may specifically include the following steps:
201. the first node device generates a user identifier of a target user on a blockchain of a blockchain system based on the registration behavior of the target user.
The first node device may be a client device used by the target user or a server corresponding to the client device, and a target application program may be installed and run on the client device used by the target user, and the target application program may provide a real-name registration function.
Taking the first node device as an example of a server corresponding to the client device, in this embodiment of the application, the client device may display a registration page of the target application, where the registration page may include an information input area and a first confirmation control, and when the client device detects a trigger operation of the target user on the first confirmation control, the client device may obtain input information in the information input area and send the input information and a registration request to the first node device, the first node device may generate, based on the registration request and the input information, a user identifier of the target user and a public key and a private key of the target user corresponding to the user identifier, where the user identifier may be used to uniquely identify one user, and the first node device may store the user identifier of the target user and the public key to a block chain of the block chain system, the private key may be stored by the target user himself. The trigger operation may be a click operation, a long-time press operation, and the like, which is not specifically limited in this embodiment of the application.
In one possible implementation, the first node device will be able to store the user identity and the public key of the target user on the blockchain based on a consensus mechanism. Specifically, each node in the blockchain system has a node identifier corresponding thereto, and each node device in the blockchain system may store node identifiers of other node devices in the blockchain system, so that the generated block is broadcast to the other node devices in the blockchain system according to the node identifiers of the other node devices, and the block is commonly identified by the other node devices. Each node device may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example.
TABLE 1
| Node name | Node identification |
| Node 1 | 117.114.151.174 |
| Node 2 | 117.116.189.145 |
| … | … |
| Node N | 119.123.789.258 |
Each node device in the blockchain system may store one identical blockchain. A block chain is composed of a plurality of blocks, fig. 3 is a schematic diagram of a block chain structure provided in the embodiment of the present application, referring to fig. 3, the block chain is composed of a plurality of blocks, a starting block 301 includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block 302 of the starting block takes the starting block 301 as a parent block, the next block 302 also comprises a block head and a block main body, and the block head stores the input information characteristic value of the current block 303, the block head characteristic value, the version number, the timestamp and the difficulty value of the parent block, and so on, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the security of the input information in the block is ensured.
In the embodiment of the present application, the input information may be a user identifier and a public key of the target user, after the node device checks the input information, the input information is stored in a memory pool, and a hash tree used for recording the input information is updated, and then, an update timestamp is updated to a time when the input information is received, and different random numbers are tried, and feature value calculation is performed for multiple times, so that a feature value obtained by calculation may satisfy the following formula:
SHA256(SHA256(version+prev_merkle_rool+ntime+nbits+x))<TARGET
wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.
Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. Then, the node where the block chain is located sends the newly generated current block to other nodes in the block chain system where the block chain is located according to the node identifiers of the other nodes in the block chain system, the other nodes perform consensus on the newly generated current block, the current block can be added to the block chain after passing the consensus, and certainly, if the current block does not pass the consensus, the block uplink operation may not be performed. Referring to fig. 4, fig. 4 is a schematic diagram of a block chain user data structure provided in this embodiment of the present application, where the user identifier and the public key of the target user may be stored in a manner shown in an area 401.
