As an embodiment, a plurality of electronic devices may communicate with each other to form a blockchain network, each electronic device serves as a blockchain node in the blockchain network, and each blockchain node maintains the same blockchain database (hereinafter, collectively referred to as "blockchain"). In addition, in the system architecture 100, each tile link point may respectively communicate with computing devices (e.g., a server/server cluster, a terminal device, etc.) of different service providers and/or clients, that is, each service provider and/or client may respectively serve as a corresponding tile link point for each service provider and/or client, and each service provider and/or client may perform operations such as reading and writing data in a tile chain through the corresponding tile link point.
It should be understood that the number of electronic devices in fig. 1 is merely illustrative. There may be any number of electronic devices, as desired for implementation.
The method for acquiring a blockchain consensus node provided by the embodiment of the disclosure can be executed in the electronic device shown in fig. 1.
The method is applied to a novel block chain network constructed by the method, the block chain network comprises a bottom layer block chain network and at least one upper layer block chain network, the bottom layer block chain network comprises a plurality of bottom layer block chain nodes, and the upper layer block chain network comprises a plurality of upper layer block chain nodes. The method is executed by an upper-layer blockchain node in a blockchain network, and the acquisition process of the blockchain consensus node provided by the disclosure is described from the upper-layer blockchain node side.
The method includes acquiring block data in an upper layer block chain corresponding to an upper layer block chain network to which a node belongs in operation S201.
Then, in operation S202, the block data is sent to the bottom layer block chain nodes, so that each bottom layer block chain node stores the block data in a bottom layer block chain corresponding to the bottom layer block chain network through consensus verification.
It can be seen that, the method shown in fig. 2 creatively constructs a composite dual-layer blockchain network including a bottom-layer blockchain network and at least one upper-layer blockchain network, for any upper-layer blockchain network, an upper-layer blockchain node in the upper-layer blockchain network can send block data in a blockchain corresponding to the upper-layer blockchain network to the bottom-layer blockchain network, the block data in the upper-layer blockchain is further stored in the bottom-layer blockchain by the bottom-layer blockchain node through common identification verification, so that the validity of the block data in the upper-layer blockchain is double verified by the upper-layer blockchain network and the bottom-layer blockchain network, the security of the block data is double protected by the upper-layer blockchain and the bottom-layer blockchain, the multi-side evidence and non-falsification characteristics of the blockchain are further enhanced, and the existing one-dimensional blockchain network is expanded into a two-dimensional blockchain network by the combination of the bottom-layer blockchain network and the upper-layer blockchain network, the method can greatly improve the transaction throughput of the whole block chain network, and meets the requirement of the current rapidly-developed transaction current situation on the block chain network.
In an embodiment of the present disclosure, sending the block data in the upper layer blockchain node corresponding to the upper layer blockchain network to which the node belongs to the method shown in fig. 2 to the bottom layer blockchain node may specifically include: and when the node serves as a common node to create a new block and adds the new block into the upper layer block chain, sending data corresponding to the new block to the bottom layer block chain node. Or when the node serves as a common node to create a new block and adds the new block into the upper layer block chain, sending data corresponding to a preset number of blocks before the new block to the bottom layer block chain node.
According to this embodiment, for any upper layer blockchain network, in one case, an upper layer blockchain node serving as a common identification node may create a new block and chain the block into the end of an upper layer blockchain corresponding to the upper layer blockchain network, and at the same time, send the related data of the new block to a lower layer blockchain network, that is, the related data of the new block is synchronized to the lower layer blockchain network while the upper layer blockchain generates the latest block, so that each lower layer blockchain node in the lower layer blockchain network can store the related data of the latest block in the upper layer blockchain into the lower layer blockchain after common identification verification, and this process is the same for each newly generated block in the upper layer blockchain. Therefore, the latest block generated in each time in the upper layer block chain can be synchronously verified by each bottom layer block chain node in the bottom layer block chain network, if the latest block has a problem, the feedback of the bottom layer block chain network can be obtained in time, and then the upper layer block chain network can avoid that a new block is subsequently linked behind the problematic block.
In another case, the upper layer block chain node serving as the common identification node may create a new block and chain the block into the end of the upper layer block chain corresponding to the upper layer block chain network, and at the same time, send the related data of a preset number of blocks located before the new block in the upper layer block chain to the lower layer block chain network, that is, the related data of the irreversible block already existing in the upper layer block chain for a period of time is synchronized to the lower layer block chain network, so that each lower layer block chain node in the lower layer block chain network can store the related data of the irreversible block in the upper layer block chain into the lower layer block chain after the common identification verification, where the process is the same for each irreversible block in the upper layer block chain. In this way, the upper block chain network synchronizes the block in the upper block chain, which is in an irreversible state after a period of time, to the bottom block chain, that is, directly synchronizes the block with higher reliability to the bottom block chain.
It can be known that, no matter which way is adopted to synchronize the block data in the upper layer block chain to the lower layer block chain, the only data stored in the lower layer block chain is legal and credible block data in each upper layer block chain, and especially, under the condition that the upper layer block chain network is not complete and the number of nodes of the upper layer block chain is small, so that the legality and the safety of the blocks stored in the upper layer block chain are low, the block data of the upper layer block chain confirmed to be credible is stored in the lower layer block chain, so that the block data is used as the legal basis of the blocks in the upper layer block chain, and the stability of the upper layer block chain network is maintained.
In operation S203, for any upper-level blockchain network, election data sent by an upper-level blockchain node having a first account balance and/or a second account balance in the upper-level blockchain network to which the node belongs is received, where the election data includes: sending information of upper layer blockchain nodes in an upper layer blockchain network to which the node belongs, wherein the upper layer blockchain nodes are selected by the upper layer blockchain nodes of the election data;
in operation S204, a consensus node is determined from the upper layer blockchain nodes selected by the election data based on the election data received in the current round, so that the consensus node performs a block packing operation in a new round.
And the numerical value in the first account of any upper-layer blockchain node is used for representing the number of the digital currency of the upper-layer blockchain node, and the numerical value in the second account of any upper-layer blockchain node is used for representing the number of the votes of the upper-layer blockchain node. If the upper blockchain node with the first account balance is the upper blockchain node holding digital currency and the upper blockchain node with the second account balance is the upper blockchain node holding a vote, the source of the election data received in the above operations may be: the system comprises upper layer blockchain nodes holding digital currency, upper layer blockchain nodes holding votes and upper layer blockchain nodes holding both the digital currency and the votes. The digital currency is virtual currency circulated by an exchange in an upper block chain network, and the vote is virtual currency which is different from the digital currency and is issued to upper block chain nodes according to a certain rule.
In an embodiment of the present disclosure, the consensus mechanism adopted by the bottom-layer blockchain is a Proof of Work (POW) consensus mechanism, which guarantees the credibility and security of the data stored in the bottom-layer blockchain at the cost of a large amount of computational resources consumed by each bottom-layer blockchain node, so as to provide effective data backup for each upper-layer blockchain network.
The method shown in fig. 2 is further described with reference to fig. 3A-3B in conjunction with specific embodiments.
Fig. 3A schematically shows an architectural schematic of a blockchain network according to an embodiment of the present disclosure.
As shown in fig. 3A, the block chain network includes a bottom block chain network 301 and three upper block chain networks 302, 303, and 304, where the bottom block chain network 301 corresponds to a bottom block chain, the three upper block chain networks 302, 303, and 304 correspond to three different upper block chains, respectively, the upper block chain network 302 corresponds to an upper block chain of a house leasing platform, the upper block chain network 303 corresponds to an upper block chain of a network data traffic sharing platform, and the upper block chain network 304 corresponds to an upper block chain of a computer computing resource sharing platform. Each upper layer blockchain network comprises a plurality of upper layer blockchain nodes, and the upper layer blockchain nodes with different shapes shown in the figure represent upper layer blockchain nodes with different function authorities.
The underlay area blockchain network employs a workload proof consensus mechanism. For any upper-layer blockchain network, a novel delegation rights and interests (D (POS + POX)) consensus mechanism obtained by improvement on the basis of a Delegated Proof of trust (DPOS) consensus mechanism is adopted to achieve consensus, the novel delegation rights and interests (D + POX)) consensus mechanism is that upper-layer blockchain nodes with digital currency are allowed to carry out consensus election, and upper-layer blockchain nodes with votes are also allowed to carry out consensus election, and the votes are issued to the upper-layer blockchain nodes contributing to the upper-layer blockchain network according to certain rules. For example, for the upper layer blockchain network 302, a corresponding number of votes are issued for the upper layer blockchain node of the provider of the rented house according to the information such as the number of houses rented, the number of days, and the like, for the upper layer blockchain network 303, a corresponding number of votes are issued for the upper layer blockchain node of the provider of the network data traffic according to the information such as the total amount of the shared network data traffic, the time, and the like, and for the upper layer blockchain network 304, a corresponding number of votes are issued for the upper layer blockchain node of the provider of the computing resource according to the information such as the total amount of the shared computing resource, the time, and the like. And further, respective consensus mechanisms of the upper layer blockchain networks are achieved, and the upper layer blockchain networks operate according to the respective consensus mechanisms.
For any upper-layer blockchain network, a plurality of upper-layer blockchain nodes form the upper-layer blockchain network, the upper-layer blockchain nodes can participate in the starting, proceeding and ending of transactions between a requester and a provider through an intelligent contract, the upper-layer blockchain nodes can issue votes through the intelligent contract, the intelligent contract is usually a code which is preset in a blockchain and can be triggered to execute, and can be operated in the blockchain nodes to execute corresponding operations after a trigger condition is met.
Fig. 3B schematically illustrates an upper zone blockchain schematic corresponding to an upper zone blockchain network according to an embodiment of the present disclosure.
As shown in fig. 3B, the upper layer blockchain may be a blockchain corresponding to any upper layer blockchain network in fig. 3A, and the upper layer blockchain corresponding to the upper layer blockchain network 302 is described as an example, where 4 block data structures currently exist in the upper layer blockchain.
After the upper layer block chain network 302 determines the common identification node of the current round through a D (POS + POX) common identification mechanism, the common identification nodes are packaged to create a new block 5, after several common identification confirmations, when the block 5 is linked into the upper layer block chain shown in fig. 3B, data corresponding to the block 5 may be sent to the bottom layer block chain network, each bottom layer block chain node in the bottom layer block chain network determines the common identification node in the bottom layer block chain network through a POW common identification mechanism, and the common identification node packages the received data corresponding to the block 5 into the new block and links the new block into the bottom layer block chain through common identification verification by each bottom layer block chain node. Or, after the upper layer block chain network 302 determines the common identification node of the current round through the D (POS + POX) common identification mechanism, the common identification node packages and creates a new block 5, after several common identification confirmations, when the block 5 is linked into the upper layer block chain shown in fig. 3B, the data corresponding to the block 2 that is already in an irreversible state before the block 5 may be sent to the bottom layer block chain network, each bottom layer block chain node in the bottom layer block chain network determines the common identification node in the bottom layer block chain network through the POW common identification mechanism, and the common identification node packages the received data corresponding to the block 2 into the new block and links the new block into the bottom layer block chain through common identification verification by each bottom layer block chain node.
Similarly, each block in the upper layer block chain corresponding to the upper layer block chain network 302 is sent to the lower layer block chain network, each block in the upper layer block chains corresponding to other upper layer block chain networks is sent to the lower layer block chain network, and legal data in all the upper layer block chains are stored in the lower layer block chain.
Furthermore, for an upper layer block chain node in any upper layer block chain network, whether the block is legal or not can be authenticated by inquiring the hash value of any block in the upper layer block chain corresponding to the upper layer block chain network where the upper layer block chain node is located from the bottom layer block chain. Thus, the blocks of each upper block chain become relatively irreversible. When a malicious node tampers a block, or a hacker attacks a block-building node to tamp the block and further to cause bifurcation, the hash value of the current upper layer blockchain can be compared with the hash value of the upper layer blockchain stored in the bottom layer blockchain, so that which of the bifurcations of the plurality of upper layer blockchains is the correct upper layer blockchain can be confirmed.
As can be seen, for any upper area blockchain network, the consensus node is determined through election data sent by each upper area blockchain node, specifically, the upper area blockchain node sending the voting data is an upper area blockchain node holding votes and/or digital currency, the election data includes information of upper area blockchain nodes in the same upper area blockchain network selected by the upper area blockchain node sending the election data, and the consensus node is determined from the upper area blockchain nodes selected by each election data within one round. Compared with the scheme for determining the consensus block chain node in the prior art, the scheme does not need to consume the calculation resources of the upper layer block chain node, and because the scheme exerts influence on the election authority of the upper layer block chain node through two modes of vote and digital currency, the development of the consensus of the upper layer block chain towards the centralization trend of digital currency gathered in a small number of upper layer block chain nodes can be effectively avoided, and the decentralization characteristic of an upper layer block chain network is maintained.
In the embodiment of the disclosure, votes can be issued to upper-layer blockchain nodes in an upper-layer blockchain network through different rules according to needs so as to exert influence on the consensus election through the votes. Preferably, votes can be issued to the upper layer blockchain nodes contributing to the upper layer blockchain network, and a right is given to the contributing upper layer blockchain node consensus nodes, so as to stimulate each blockchain node in the same upper layer blockchain network to maintain the normal operation of the upper layer blockchain network together.
Specifically, as an alternative embodiment, the method shown in fig. 2 further includes: receiving transaction information sent by an upper layer blockchain node in an upper layer blockchain network to which the node belongs; determining a preset numerical value according to the transaction information, wherein the preset numerical value is used for representing a numerical value added to a second account of an upper layer blockchain node of a transaction object provider corresponding to the transaction information; and sending the preset numerical value to each upper layer block chain node in the upper layer block chain network to which the node belongs, so that each upper layer block chain node stores the preset numerical value into the corresponding upper layer block chain.
Optionally, different upper tier blockchain networks correspond to different upper tier blockchains, the different upper tier blockchains storing transaction information corresponding to different types of transactions.
The embodiment describes a scheme for issuing votes to an upper layer blockchain node in an upper layer blockchain network, where transaction information is information of events in which transactions are performed between the upper layer blockchain nodes, and under different conditions, the upper layer blockchain node serving as a transaction provider may be a full node or a light node, and the upper layer blockchain node serving as a transaction purchaser may be a full node or a light node; the full node is a blockchain node capable of performing a block data structure packing operation, performing a data recording operation, and running an intelligent contract, while the light node cannot perform the block data structure packing operation and the data recording operation and cannot run the intelligent contract, but may have a first account and a second account regardless of the full node or the light node. The transaction information sent by the upper layer blockchain node comprises at least one of the following items: information of the transaction object, information of the transaction object provider, and information of the transaction object purchaser. And issuing a vote with a preset numerical value to the upper layer blockchain node serving as a transaction provider. When the vote is issued, the identification information of the upper layer blockchain node as the transaction provider and the determined preset numerical value can be broadcasted to each upper layer blockchain node together, so that each upper layer blockchain node with data recording capability correspondingly stores the identification information and the preset numerical value of the upper layer blockchain node as a transaction provider into a respective blockchain database, the corresponding relation between the identification information of the upper block chain node as a transaction provider and a preset numerical value is uniformly recorded in the upper block chain, namely, information which represents that a preset value is added to a second account which is an upper layer blockchain node of a transaction object provider is uniformly recorded, this information is co-supervised by each upper blockchain node in the blockchain, and in accordance with the above, this information is also synchronized into the underlying blockchain to ensure the monitorability and irreversibility of the vote issuing process.
As an optional embodiment, the determining the preset value according to the transaction information includes: and determining the preset value according to the total amount of the transaction matters corresponding to the transaction information. The method comprises the steps of measuring the contribution of an upper layer blockchain node serving as a provider of the transaction to an upper layer blockchain network where the upper layer blockchain node is located according to the total amount of the transaction, and issuing votes corresponding to the contribution of the upper layer blockchain node serving as the provider of the transaction.
Based on the above description, the beneficial effects of the present disclosure are as follows:
firstly, the present disclosure adopts a structure of a bottom layer blockchain network and a layer blockchain network, different upper layer blockchain networks correspond to different application scenes, and the corresponding upper layer blockchain records data of different application scenes, and this structure expands a one-dimensional blockchain into two dimensions, thereby greatly increasing the transaction throughput of the whole blockchain network.
