Example two
The present embodiment further supplements the method provided in the first embodiment.
As shown in fig. 3, a schematic flow chart of the block chain generation method provided in this embodiment is shown.
As a practical way, on the basis of the first embodiment, optionally before the step 101, the method may further include:
in step 2011, at least two sets of initial parameters are obtained, where each set of initial parameters corresponds to a different service type.
Specifically, the initial parameter may include information used to create a created block, such as an initial account and a random number, and may set a service type corresponding to the initial parameter, that is, a service type of transaction data managed by a block chain corresponding to the created block, so that a block chain for managing transaction data of different service types may be created. Each blockchain may be referred to as an ledger.
The primary account may include related information such as a blockchain address, a public key, a certificate, an identity, and the like, and may be specifically set according to actual requirements.
Specifically, after at least two sets of initial parameters are obtained, a corresponding created block, that is, the first block of at least two block chains, may be created according to each set of initial parameters.
For the blockchain corresponding to each created block, a blockchain identifier may be set for the blockchain, and the blockchain identifier may be generated for the blockchain according to some existing unique identifier generation methods, which is not limited in the embodiment of the present application.
Illustratively, a commodity order blockchain, a commodity information traceability blockchain, a supply chain financial blockchain, and the like may be created.
Alternatively, a hash value generated from the block information included in the created block may be used as the block chain identifier of the block chain corresponding to the created block. Specifically, any practicable hash algorithm may be used to generate the hash value of the block information included in the created block. The block information included in the created block may include information such as block header information and block body information, where the block header information may further include initial account information, random number information, and some other security information, and the like. For the concrete embodiment of various types of information, the embodiment of the present application is also not limited, and for example, the information may be encrypted or hash-calculated, and may be set according to actual requirements.
Optionally, determining a block chain identifier for a block chain corresponding to the created block may specifically include:
generating a hash value corresponding to the created block according to the block information included in the created block; and taking the hash value corresponding to the created block as the block chain identifier of the block chain corresponding to the created block.
Specifically, any practicable hash algorithm may be used to generate the hash value of the block information included in the created block. The block information included in the created block may include information such as block header information and block body information, where the block header information may further include initial account information, random number information, and some other security information, and the like. For the concrete embodiment of various types of information, the embodiment of the present application is also not limited, and for example, the information may be encrypted or hash-calculated, and may be set according to actual requirements.
Optionally, before generating a new block on the block chain corresponding to the target block chain identifier, the method may further include:
and carrying out consensus processing on the to-be-processed transaction data corresponding to different target block chain identifications in parallel.
Specifically, since the method of the embodiment of the present application can generate a plurality of block chains, although one block chain needs to be generated block by block according to a time sequence, the block chains can be generated in parallel between different block chains. Therefore, for the transaction data to be processed with different service types, the consensus processing can be performed in parallel according to the different target block chain identifications included in the transaction data, so that the transaction data can be input in parallel. The management of different block chains can be independent and not influenced mutually, and the efficiency of block chain data management is further improved.
For example, the pending transaction data of multiple service types may be sent in parallel to initiate a consensus request, that is, sent in parallel to other blockchain nodes in the blockchain network, and the consensus is achieved by the other blockchain nodes. The specific consensus operation may be the prior art, and is not described herein.
Optionally, the transaction data to be processed of each service type corresponds to a plurality of operation types; correspondingly, step 103 may specifically include:
and step 1031, for the transaction data to be processed of each service type, generating a mercker merkle tree according to the transaction data to be processed and the operation type corresponding to the transaction data to be processed.
And step 1032, generating a new block on the block chain corresponding to the target block chain identification according to the hash value of the root node of the merkle tree.
The operation type refers to a type of transaction data, a merkle tree, or information included in the block, for example, a type of transaction data includes specific transaction information, account information, verification information, and the like, and the account information may include information such as a block chain address, a public key, a certificate, an identity, and the like. The merkle tree includes types such as a root node, a middle node, a leaf node, etc., the block may include types such as block header information, block body information, etc., or the block header information includes timestamp information, random number information, a hash value of the root node of the corresponding merkle tree, etc., the operation type may be set according to an actual requirement, and the specific partition granularity may also be set according to the actual requirement, which is not limited in the present application.
For the to-be-processed transaction data of each service type, for example, the to-be-processed transaction data of a commodity order service type, it may include specific transaction information (commodity information, commodity quantity, customer information, etc.), account information (block chain address, public key, certificate, etc.), verification information (identity information, signature information), etc. operation types, and may perform fine-grained division on the to-be-processed transaction data according to these operation types, and generate a merkle tree according to the divided granularity, where the merkle tree represents index information of the divided granularity data. And generating a new block on the block chain corresponding to the target block chain identification according to the hash value of the root node of the merkle tree, wherein the block header information of the generated new block comprises the hash value of the root node of the merkle tree. Illustratively, a hash value is generated together as the block header information of the new block according to the hash value of the parent block referenced by the new block, the hash value of the root node of the merkle tree, a timestamp, a random number, and the like. Of course, the generated block header information may also include some other related information, such as information for security measures, and the like, which may be specifically set according to actual requirements, and the embodiment of the present application is not limited.
The specific generation manner of the merkle tree is the same as or similar to that of the merkle tree in the prior art, and is not described herein again.
Optionally, each piece of granularity data after the transaction data to be processed is finely divided may be stored in KEY VALUE data, that is, KEY-VALUE data is stored in a distributed manner. And generating a KEY for each piece of granularity data, wherein the specific granularity data is used as the VALUE corresponding to the KEY.
Fig. 4 is a schematic diagram illustrating a relationship between a block chain, a merkle tree and key-value data provided in this embodiment. K represents KEY, V represents VALUE, and K can uniquely identify V, namely one V can be uniquely determined according to one K. G0-G3 respectively indicate root nodes corresponding to the respective tiles, Y indicates leaf nodes, and M indicates intermediate nodes. V1 and V2 represent two versions of the same granularity data, namely V2 after a change is made to a certain granularity data V1. The specific KEY-VALUE association relationship is the prior art and is not described herein again. Each block corresponds to a root node of a merkle tree, and as the number of blocks increases, a root node corresponding to a previous block may become a child node of a next block adjacent to the previous block, so that the merkle tree increases as the number of blocks increases, the integrity of block chain data is maintained in this way, and the relationship between the block and each piece of granularity data after the transaction data to be processed is divided is conveniently maintained, for example, a hash value of the root node corresponding to the block can be obtained from the block, hash values of two child nodes (possibly middle nodes) below the root node can be obtained from the hash value of the root node, hash values of two child nodes below the child nodes can be obtained from the hash values of the child nodes until hash values of leaf nodes are obtained, a hash value of each piece of granularity data, such as a hash value of a key value to KV, can be obtained from the hash values of the leaf nodes, therefore, the key value pair can be obtained from the hash value of the key value pair, that is, one piece of granularity data can be obtained.
Alternatively, the data may be stored in the form of identification-data or some other implementable form for each granularity, not limited to key-value pair form.
As another practical manner, on the basis of the first embodiment, optionally, after determining a block chain identifier for a block chain corresponding to a created block, the method may further include:
and storing the related data of the block chains corresponding to different block chain identifications in a classified manner according to the block chain identifications.
Specifically, the related data of the blockchain may include data of the blockchain itself and some data other than the data written in the block, for example, the hash value of only the root node of the merkle tree is written in the block, while the merkle tree and the transaction data to be processed are not written in the block and need to be stored, and the specific related data may be set according to actual requirements. Since a plurality of block chains can be generated, each block chain has a corresponding block chain identifier, in order to facilitate management of relevant data corresponding to each block chain, such as query, update, and the like, the relevant data of each block chain can be stored in a sorted manner according to the block chain identifiers. The specific storage form may be any implementable form, and this embodiment is not limited, as long as the related data of different blockchains are stored in a classified manner, and the corresponding data can be conveniently found according to the blockchain identifier.
It should be noted that the respective implementable modes in the present embodiment may be implemented individually, or may be implemented in combination in any combination without conflict, and the present application is not limited thereto.
In the method for generating a block chain provided by this embodiment, transaction data to be processed is obtained, where the transaction data to be processed includes transaction data of at least one service type, a target block chain identifier corresponding to the transaction data to be processed of each service type is determined according to the transaction data to be processed of each service type, and a new block is generated on the block chain corresponding to the target block chain identifier according to the transaction data to be processed of each service type, so that each block chain link point in one block chain network can commonly maintain multiple block chains, and thus transaction data of different service types can be written into different block chains for management, which can provide better flexibility and manageability, and improve efficiency of data management. And a plurality of block chains are generated in a block chain network formed by a group of block chain link points, so that the resources of the block chain nodes can be multiplexed, and more cost is not required to be generated while better flexibility and manageability are obtained. And the consensus processing can be performed in parallel, so that the data processing efficiency is further improved. The transaction data to be processed can be divided in a fine-grained manner, a merkle tree is generated, only the hash value of the root node of the corresponding merkle tree needs to be stored in the block, and all the transaction data blocks to be processed do not need to be stored, so that the flexibility of data management is further improved.
