The terms "first", "second", and the like in the description and claims of the present disclosure and in the drawings are used for distinguishing between different objects and not for limiting a particular order.
It should be further noted that, in the embodiments of the present invention, each of the following embodiments may be executed alone, or may be executed in combination with each other, and the embodiments of the present invention are not limited in this respect.
The names of messages or information exchanged between devices in the embodiments of the present disclosure are for illustrative purposes only, and are not intended to limit the scope of the messages or information.
The technical solutions of the embodiments of the present invention are further described by the following detailed description with reference to the accompanying drawings.
The block chain network in this embodiment includes a plurality of block chain nodes, the plurality of block chain nodes are divided into a plurality of block chain segments according to a predetermined configuration, the plurality of block chain segments form a pyramid-shaped hierarchical relationship, and each block chain segment maintains one block chain.
Any block link point is used for: monitoring the transaction or block broadcast by the neighbor node in the block chain segment to which the block chain link point belongs; if the transaction broadcasted by the neighbor node is received, verifying the transaction, and adding the transaction passing the verification into the block being constructed; and if the block broadcasted by the neighbor node is received, verifying the block and linking the block which passes the verification to a block chain maintained by the block chain fragment.
According to one or more embodiments of the present disclosure, the forming a pyramid hierarchical relationship of the plurality of blockchain shards may further include: in addition to the top-level blockchain segment, each blockchain segment is anchored to a blockchain node in the previous-level blockchain segment. Fig. 1 is a schematic structural diagram of a data chain in a blockchain network according to an embodiment of the present invention, and as shown in fig. 1, a plurality of blockchain nodes in the blockchain network are divided into 6 blockchain fragments according to a predetermined configuration, where the 6 blockchain fragments include 1 top-level chain fragment, 2 secondary-level chain fragments, and 3 secondary-level chain fragments. It should be noted that the number of layer levels of the blockchain and the number of the blockchain fragments of each layer can be specifically set according to the application requirement, which is not limited in this embodiment.
After each blockchain fragment is anchored to a blockchain node in the previous-level blockchain fragment, information exchange between blockchain fragments of adjacent levels can be realized through the blockchain link points.
For example, according to one or more embodiments of the present disclosure, in addition to the block link points in the top layer block chain network, any block link point may further summarize, through an intelligent contract, block chain data maintained by the block chain segment to which the block link point belongs, and report a summary result to a top layer block chain node anchored by the block chain segment to which the block link point belongs, so as to report data to a directly associated top layer block chain segment from a lower layer block chain segment.
For another example, according to one or more embodiments of the present disclosure, in addition to the block link points in the bottommost block chain network, any block link point may also monitor a broadcast transaction issued by an upper-level block link point anchored by a block chain segment to which the block link point belongs, and verify and process the monitored broadcast transaction.
According to one or more embodiments of the present disclosure, the plurality of blockchain nodes may be divided into a plurality of segments according to a plurality of predetermined configurations, for example, the plurality of blockchain nodes are divided into a plurality of segments according to a geographic area corresponding to a transaction range, and each segment is anchored to a blockchain node in a previous level of blockchain segments according to the geographic area corresponding to the transaction range. Specifically, the actual management hierarchy of the geographic region division may be mapped onto block chains, a separate block chain (which may be referred to as a secondary chain) is divided for each hierarchy unit and authenticated in a top chain (which may be referred to as a top chain), the authenticated secondary chain is to synchronize the transaction height to the top chain in real time, and the transaction hash of the secondary chain is to be packed and submitted to the top chain for storage. And the secondary chain performs signature hash processing on the transaction after receiving the transaction request, packages and submits the transaction hash to the top-level chain for evidence storage after the transaction accumulation reaches the configuration cache number, and submits the block height of the secondary chain to the top-level chain, so that the autonomy of areas and organizations is realized, and the transaction pressure and the storage pressure of the block chain are reduced.
For another example, the multiple blockchain nodes may also be divided into multiple segments according to a company organization architecture corresponding to the transaction processing range, and each segment is anchored to one blockchain node in the previous blockchain segment according to the company organization architecture corresponding to the transaction processing range. Fig. 2 shows a structural diagram of an example of a blockchain network used in an enterprise corresponding to the fragmentation mode, and as shown in fig. 2, a service scenario of this example aims to solve the problem of account synchronization when an office and a sub-company network cannot communicate with each other, and meanwhile, normal consumption of an employee is not affected in the case of network outage.
1. And (3) budget planning by the group: and the group integrally plans the budget of the employee card, introduces the summary budget into an account according to the subsidiary companies at the beginning of the period, and stores the budget integrally planned data in a top-level chain in an uplink manner.
2. The top chain and the secondary chain perform budget synchronization: the group budget can be synchronized to the secondary chain after being recorded into the top chain, the subsidiary company can perform subsequent operation after taking the budget, and the operation can be automatically and synchronously executed through an intelligent contract.
3. And the subsidiary company carries out account recharging, namely the subsidiary company recharges the employee card based on the headquarter and transmits recharging data to the secondary chain.
4. And the secondary chain synchronize the balance of the employee account: namely the office synchronous employee card recharging information.
5. And the employee swipes the card at the office for consumption, and submits the cancellation request to the corresponding secondary chain.
6. And the corresponding secondary chain locally accounts the consumption information of the employee card, signs and authenticates the authenticity of the transaction, and hashes and summarizes the transaction.
7. The secondary chain submits a summary account of the data chain to the anchored secondary chain: the secondary chain synchronizes the summary transaction hash and the final confirmation account status to the subsidiaries, and the secondary chain verifies the chain status, the initial parameters and the signature information during synchronization.
8. The secondary chain summarizes the accounts: the general ledger is collected after the accounts of all the office places are collected, the account balance information of the employee card is updated, and synchronization is carried out among other office places, so that the employee can cross the office places to hold the card for consumption.
9. And the secondary chain carries out account synchronization to the top chain and synchronizes the accounts to the group general ledger.
10. The top chain examines the accounts, including the summary settlement, and orchestrates the expenditure.
According to the technical scheme, a large number of actual services are processed in a plurality of secondary chains in a slicing mode, the distribution situation of transactions in a whole chain is effectively dispersed, and the concurrent processing capacity of the whole chain network structure is effectively improved. Since a large amount of actual raw data is stored in the subchains, the storage is dispersed among the subchains, and the data storage pressure on the entire chain network becomes small, so that the entire chain network can process a large amount of transaction data. Because of the non-falsification on the secondary chain and the bidirectional anchoring with the top chain, the secondary chain can work off the net and eventually synchronize the result with the top chain.
Fig. 3 shows a schematic flow chart of a data storage method based on a blockchain network according to an embodiment of the present invention, where the blockchain network may be a federation chain or a private chain, and includes a plurality of blockchain nodes, the plurality of blockchain nodes are divided into a plurality of blockchain fragments according to a predetermined configuration, the plurality of blockchain fragments form a pyramid-like hierarchical relationship, and each blockchain fragment maintains a blockchain, and the method is executed by a blockchain node, and the method includes:
in step S310, the transaction or block broadcast by the neighbor node in the blockchain segment to which the blockchain link point belongs is monitored.
The block link point verifies the identity information of the broadcast transaction or the block chain node of the block, determines whether the block link point is a neighbor node in the block chain segment to which the block link point belongs, and can verify through the IP address of the block link point.
For example, after the blockchain network is fragmented and layered, a configuration file may be generated according to the IP address of each blockchain node, so as to specify the hierarchy and fragment to which each node belongs. When the block chain link points verify the identities of other block chain nodes, verification can be performed according to the configuration file.
In step S310, if the transaction broadcasted by the neighboring node is received, the transaction is verified, and the transaction passing the verification is added to the block being constructed.
In step S310, if the block broadcasted by the neighboring node is received, the block is verified, and the verified block is linked to the block chain maintained by the block chain fragment.
When receiving a new transaction and a new block sent by a neighbor node in the segment, the method firstly verifies whether the transaction and the block are valid or not, including a digital signature in the transaction, a workload certification in the block and the like, and only the transaction and the block which pass the verification are processed (namely the new transaction is added into the block which is being constructed, and the new block is linked to the block chain) and forwarded to prevent invalid data from being continuously transmitted.
According to one or more embodiments of the present disclosure, in addition to the top-level blockchain segment, each blockchain segment is anchored to a blockchain node in the previous-level blockchain segment, and a node in the lower-level blockchain segment can implement information interaction between the upper-level blockchain segment and the lower-level blockchain segment through the anchored previous-level blockchain link node.
According to one or more embodiments of the present disclosure, the plurality of blockchain nodes may be divided into a plurality of segments according to a plurality of predetermined configurations, for example, the plurality of blockchain nodes are divided into a plurality of segments according to a geographic area corresponding to a transaction range, and each segment is anchored to a blockchain node in a previous level of blockchain segments according to the geographic area corresponding to the transaction range. Specifically, the actual management hierarchy of the geographic region division may be mapped onto block chains, a separate block chain (which may be referred to as a secondary chain) is divided for each hierarchy unit and authenticated in a top chain (which may be referred to as a top chain), the authenticated secondary chain is to synchronize the transaction height to the top chain in real time, and the transaction hash of the secondary chain is to be packed and submitted to the top chain for storage. And the secondary chain performs signature hash processing on the transaction after receiving the transaction request, packages and submits the transaction hash to the top-level chain for evidence storage after the transaction accumulation reaches the configuration cache number, and submits the block height of the secondary chain to the top-level chain, so that the autonomy of areas and organizations is realized, and the transaction pressure and the storage pressure of the block chain are reduced.
For another example, the multiple blockchain nodes may also be divided into multiple segments according to a company organization architecture corresponding to the transaction processing range, and each segment is anchored to one blockchain node in the previous blockchain segment according to the company organization architecture corresponding to the transaction processing range. Fig. 2 shows a structural diagram of an example of a blockchain network used in an enterprise corresponding to the fragmentation mode, and as shown in fig. 2, a service scenario of this example aims to solve the problem of account synchronization when an office and a sub-company network cannot communicate with each other, and meanwhile, normal consumption of an employee is not affected in the case of network outage.
According to the technical scheme, different data can be linked to different levels and block chains of different fragments for storage, transactions of the same level can be dispersed into each block chain fragment for processing, the concurrent processing capacity of a block chain network can be effectively improved, and massive transaction data processing can be supported.
