the main chain and the sub-chain have no fixed specification, but the general main chain, namely all the functions, is a block chain network with complete functions, and mainly comprises distributed nodes, decentralized accounting, assets and the like. The sub-chains are designed to expand the use range of the main chain without affecting the efficiency of the main chain, usually one service system or function module corresponds to one sub-chain, each sub-chain supports respective service or function, and all the sub-chains synchronize data to the main chain in batches through a chain crossing technology to perform validity confirmation.
The sub-chain itself is also a block chain network, which may be homogeneous in design with the main chain (same technical architecture) or heterogeneous.
The request node is connected with the sub-chain in a chain crossing mode, and the verification node is connected with the main chain in a chain crossing mode, so that the communication function, the asset transfer function and the data verification function of the main chain and the sub-chain are realized.
As a further embodiment of the present invention, each node in the main chain is decentralized and records service data using a distributed architecture; each node digitally encrypts the transaction operation and broadcasts the transaction operation to a network platform based on a regional chain through a digital signature; all nodes verify the signature validity and synchronize the data in real time.
From the network topology perspective, the network platform based on the area chain is not a traditional centralized single node or a centralized plurality of copy nodes, but a decentralized distributed design that a plurality of participants maintain one account book copy respectively.
From the perspective of transaction confirmation flow, a single node or an administrator does not perform accounting any more, but multiple participants perform accounting together, the accounting sequence is random, only one accounting node is provided at the same time, but other nodes perform confirmation, and finally, the transaction is effective after most nodes confirm to pass.
As a further embodiment of the present invention, a secure communication method is provided based on the area link network of the present invention, which specifically includes the following steps:
a network platform secure communication method based on a regional chain comprises the following steps:
the method comprises the steps that firstly, each node in the network is decentralized, and service data are recorded by adopting a distributed architecture;
secondly, each node digitally encrypts the transaction operation and broadcasts the transaction operation to a network platform based on a regional chain through a digital signature;
thirdly, verifying signature validity and synchronizing data in real time by all nodes;
fourthly, checking the data of each node by adopting a consensus algorithm;
and fifthly, when the partial node data are not checked to be consistent, recovering the service data recorded in the step one.
As a further embodiment of the present invention, the method for recovering the service data recorded in the first step includes: when data of one node is lost, the latest block number X of the node is sent to the network, other nodes reply the latest block numbers Yi of the nodes, abnormal nodes with data loss compare all replies through a consensus algorithm, block numbers Y which are considered legal by 2/3X N +1 nodes are found, then block information with numbers between [ X +1, Y ] is requested to the network, the block information is re-derived one by one after the reply is received, and finally synchronization is achieved with the network; when abnormal data exists in one node, bifurcation is generated in the process of re-derivation, 2/3N +1 nodes are selected to be considered as legal bifurcation through a consensus algorithm, and finally consistency is achieved.
Since the block chain network in operation cannot always run at full load, and runs at full load during the re-deriving, the re-deriving is completed quickly.
As a further embodiment of the present invention, the re-deriving is used to re-execute all transaction records in the previous period of time according to the original sequence and logic, so as to achieve the purpose of being consistent with the transaction record data of each node on the regional chain network platform.
As a further embodiment of the present invention, the nodes include ledger nodes of whitestripe operators, banks, logistics, suppliers, distributors, farmers, and regulatory agencies.
As a further embodiment of the present invention, the ledger node includes: the account book synchronization method comprises core production nodes and synchronization nodes, wherein the core production nodes carry out random alternate accounting, only one core production node is arranged at the same time, other synchronization nodes only carry out account book synchronization, and all account book contents are the same, namely, a network system is externally provided with an account book, and distributed copies are arranged inside the network system and are respectively stored in a plurality of nodes.
As a further embodiment of the invention, the consensus algorithm includes delegation rights attestation DPos and asynchronous byzantine fault tolerant bft.
The delegation rights and interests prove DPos is used for delegating a certain number of agent nodes to conduct transaction confirmation and block production by all rights and interests holders, is a weakly centralized design, gives consideration to centralization and system efficiency, and enables the agent nodes to be variable in real time and the block output sequence to be changed randomly.
The asynchronous Byzantine fault-tolerant aBFT enables all transactions to pass through two steps of pre-proposal confirmation and proposal confirmation, wherein each step needs 2/3 × N +1 nodes to confirm to pass, N is the total agent quantity, and different from the traditional BFT consensus algorithm, the asynchronous Byzantine fault-tolerant aBFT is asynchronous in implementation, and a certain real-time property is sacrificed to achieve high expandability and reduce bandwidth pressure.
The delegation rights prove that the DPos and the asynchronous Byzantine fault-tolerant aBFT consensus algorithm are combined and combined, and the high efficiency and the reliability of consensus are guaranteed.
The blockchain network is open, and any person can participate in the operation of the blockchain network, but for ordinary participants, the cost (service environment construction) is required. The way of compromising is by mortgage the right in hand (indicating that he has the right to the blockchain network, which can be understood as shares) to a part of the nodes, i.e. proxy nodes, usually large organizations, that have the ability and capital to operate the network, and the common participants participate in the blockchain network operation in this indirect way.
As a further embodiment of the present invention, the ownership rights holders are participants who support benefits for the blockchain network, and are embodied in a manner of holding a pass-through.
As a specific embodiment of the invention, a buyer purchases agricultural products from a supplier represented by a farmer in the form of a purchase order through a network platform, and the order is validated by the buyer, the supplier and a white-stripe operator;
after the order takes effect, the farmer as a seller can deliver goods and submit logistics information through the platform, and the buyer completes goods receiving confirmation according to the actual conditions of the goods and the logistics information;
after the seller delivers the goods, the white stripe operator sends a white stripe coupon and payment amount to the seller through the platform; after receiving the white-bar coupons and the payment amount, the seller initiates withdrawal application through the platform; after the withdrawal application is confirmed by the white stripe operator and the bank, the bank completes the payment under line program.
