It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for processing information in accordance with the present application is shown. The method for processing information comprises the following steps:
and step 201, receiving and recording target transaction information by using the block chain.
In this embodiment, a method execution agent (e.g., a server as shown in fig. 1) for processing information may be run with a blockchain. The block chain is a chain data structure formed by combining blocks in a sequential connection mode according to a time sequence, and is a distributed account book which is guaranteed in a cryptology mode and cannot be tampered and forged. One or more transaction messages may be recorded in each of the blocks constituting the block chain. In practice, each tile in the chain of tiles may record transaction information for a plurality of activities (e.g., treasure snatching activities, lottery activities, etc.), each of which may correspond to an identifier for distinguishing between different activities.
Generally, a block is composed of a block header and a block body. The block header of the block may record the hash value of the last block. Here, the hash value of the tile may be referred to as a tile hash value. Each chunk in the chain of chunks may contain the chunk hash value of the last chunk. In practice, the Hash value may also be referred to as a Hash value (Hash values, hash codes, hash sums, or hashes), and the Hash value is a value generated by a Hash Function (Hash Function, may also be referred to as a Hash algorithm, hash Function, or the like). The hash function may compress information or data into a digest so that the amount of data becomes small, fixing the format of the data. The hash function may mix data to create a new data, and the created data is a hash value. The hash value is typically represented by a short string of random letters and numbers. The tile body may typically be used to record transaction information over a period of time. It should be noted that the above-mentioned block chain structure and the information recorded in the blocks are well-known technologies that are widely researched and applied at present, and are not described herein again.
In this embodiment, the execution body may receive and record the target transaction information by using the blockchain. The target transaction information may be transaction information generated by a user participating in a target activity (e.g., a certain activity pre-specified by a technician). In practice, after a target activity begins, users may participate in the target activity and may send information to the blockchain, and each user may be predefined to participate only once. After the execution body confirms that the target activity starts or receives an instruction for starting the target activity, the target transaction information can be received and recorded by using the block chain.
In some optional implementations of this embodiment, the target transaction information may include: identification of the target activity, any string of characters entered by the user. In practice, the user may browse a page of the target activity, which may contain information for prompting the user to make any character string input, such as "please input any content in the lower text box", using a client (e.g., terminal devices 101, 102, 103 shown in fig. 1). The user can input any content at the corresponding position, and after submitting the request for participating in the target activity, target transaction information containing the content input by the user and the identification of the target activity is generated and recorded in the block. Since the target transaction information includes any character string input by the user, for the execution main body, the content input by the user is random, and the target hash value and the final hash value of each block are determined by using the random content, so that each user can fairly influence the calculation result of the final hash value, and the fairness of determining the target user is improved.
In response to determining that the preset end condition is satisfied, a final hash value is determined based on the block hash value of the block newly generated in the block chain and the target hash value of the block 202.
In this embodiment, the execution body may store a preset end condition in advance, and in response to determining that the end condition is satisfied, the execution body may determine a final hash value based on the chunk hash value of the newly generated chunk in the chunk chain and the target hash value of the chunk. The preset ending condition may be various conditions, for example, the proportion of the total number of the users who participate in the game reaches a preset value, the time reaches a preset time, and the like. Here, if it is determined that the predetermined end condition is satisfied, the chunk hash value of the newly generated chunk in the chunk chain and the target hash value of the chunk may be used as inputs of the hash function, and data output by the hash function may be used as a final hash value.
It should be noted that, after the target activity starts, the target hash value of each chunk generated in the blockchain is determined based on the target transaction information recorded by the chunk, the chunk hash value of the previous chunk of the chunk, and the target hash value of the previous chunk. Specifically, the execution body may use a newly generated chunk running in the blockchain at the start time of the target activity as an initial chunk, and use a preset value (e.g., 0) as a target hash value of a previous chunk of the initial chunk. For an initial block, the target transaction information recorded in the initial block, the block hash value of the previous block, and the target hash value of the previous block (i.e., the preset value) may be used as inputs of a hash function, and the data output by the hash function may be used as the target hash value of the initial block. Then, for each block generated in sequence, the target transaction information recorded by the block, the block hash value of the block immediately preceding the block in the block chain, and the target hash value of the immediately preceding block may be used as inputs of the hash function, and the data output by the hash function may be used as the target hash value of the block until the above-mentioned end condition is satisfied. When the above termination condition is satisfied, the hash value of the block newly generated in the block chain and the target hash value of the block may be used as the input of the hash function, and the data output by the hash function may be used as the final hash value.
In some optional implementations of the embodiment, the ending condition may be that the number of people participating in the target activity reaches a preset value or the block height reaches a preset value. The block height may be the sum of the initial block height and the required number of blocks, and the required number of blocks may be obtained by: firstly, determining the ratio of the total duration of the target activities (which can be preset) to the minimum duration of block generation (which can be statistically determined in advance); and then, rounding the ratio carry. The number obtained after rounding is the number of the required blocks. Wherein the height of the initial block may be an order of the initial block in the block chain.
And step 203, matching the final hash value with the block chain account address of the user related to the target transaction information of each block record, and determining the target user based on the matching result.
In this embodiment, the execution agent may match the final hash value with a blockchain account address of a user related to the target transaction information of each blockchain record, and determine the target user based on a matching result. Each block can record one or more target transaction information, each user can participate in a target activity only once, and each target transaction information corresponds to one user. Each user has a blockchain account address. In practice, each user involved in the blockchain has a public key and a private key, and for each user, the public key of the user can be used to generate the blockchain account address of the user through a one-way hash algorithm. Here, the user's blockchain account address may be a string of various forms (e.g., may be a 42-bit string beginning with "0 x"). It should be noted that the generation method of the blockchain account address of the user is a well-known technology widely researched and applied in the field of blockchain technology, and is not described herein again.
In some optional implementations of this embodiment, the executing entity may directly match the final hash value with the blockchain account address of each user involved in the target transaction information of each blockrecord. And determining the user corresponding to the block chain account address which indicates the closest match result to the final hash value as a target user. The number of target users is not limited to one, and may be plural. At this time, a plurality of users may be sequentially selected as target users in the descending order of the proximity.
In some optional implementations of this embodiment, the executing entity may determine the target user according to the following objectives:
and step one, respectively extracting the target byte of the final hash value and the target byte of the block chain account address of the user related to the target transaction information of each block record, and converting each extracted target byte into data of a target data type. The target byte may be a byte at one or more positions (e.g., the last 8 bytes) preset by a technician. The target data type may be a data type (e.g., unsigned 64-bit integer data type uint 64) preset by a technician.
And secondly, matching the target byte converted data extracted from the final hash value with the target byte converted data extracted from each blockchain account address, and determining a target user based on the matching result. Here, the target byte-converted data extracted from the final hash value may be set as target data, and the user corresponding to the data closest to the target data among the target byte-converted data extracted from each block chain account address may be set as the target user. The number of target users is not limited to one, and may be plural. In this case, a plurality of users may be sequentially selected as target users in descending order of proximity to the target data.
In some optional implementation manners of this embodiment, after determining the target user based on the matching result, the executing body may further push prompt information to the target user, where the prompt information may be used to prompt the user to be determined as the target user.
In some optional implementations of the embodiment, the prompt information may include winning result information, and the winning result information may include a name of the target user, personal information, and the like. After determining the target user based on the matching result, the execution body may further generate a winning result page, wherein the winning result page may include the winning result information. After the winning result page is generated, the execution body can push the winning result page to the client used by each user participating in the target activity, so that each user can browse the winning result.
With continuing reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for processing information according to the present embodiment. In the application scenario of fig. 3, after the activity starts, the server may receive and record the target transaction information by using the blockchain, and for each chunk sequentially generated in the blockchain after the activity starts, the server may determine the target hash value of the chunk based on the target transaction information recorded by the chunk, the chunk hash value of the previous chunk, and the target hash value of the previous chunk. And then determining whether a preset ending condition is met, if not, continuing to determine the target hash value after the next block is generated until the ending condition is met. After determining that the end condition is met, determining a final hash value based on the block hash value of the current newly generated block and the target hash value of the block. And finally, matching the final hash value with the block chain account address of the user related to the target transaction information of each block record, and determining the target user based on the matching result.
In the method provided by the embodiment of the application, the target transaction information is received and recorded by using the block chain, then, in response to the fact that the preset ending condition is met, a final hash value is determined based on the block hash value of the block newly generated in the block chain and the target hash value of the block, finally, the final hash value is matched with the block chain account address of the user related to the target transaction information recorded by each block, and the target user is determined based on the matching result. The block chain has the characteristics of decentralization and non-falsification, and does not need to depend on numerical values provided by a third party, so that the fairness of determining a target user is improved, and meanwhile, the block chain is used for storing calculation results, and the fairness of the checking activities of an auditing department can be guaranteed.
