It is essentially a decentralized database, a string of data blocks associated by cryptography, each data block containing information of a batch of network transactions for verifying the validity (anti-counterfeiting) of the information and generating the next block. In a narrow sense, the blockchain is a distributed account book which is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence and is guaranteed in a cryptographic mode and cannot be tampered and forged. Broadly, the blockchain technique is a completely new distributed infrastructure and computing approach that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, utilizes cryptography to secure data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data.
The current blockchain mainly issues service Token based on an intelligent contract mode, for example, ERC2.0 of an ethernet workshop, and the value is only circulated in the chain, each chain is an independent and vertical closed system, and the chains gradually become incompatible information islands, more like a local area network. The cooperation and interconnection of different blockchain platforms for different application domains becomes crucial. There is a need to enable blockchains to be used in different scenarios, including financial, manufacturing, and government regulations. Due to limited interoperability, the scalability of the blockchain is also greatly affected, and the storage capacity and transaction throughput cannot meet the multi-scenario usage.

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
A blockchain account: and based on a public and private key system of asymmetric encryption, generating a public and private key pair, then performing a corresponding hash algorithm (MD 5, SHA, SM3 and the like) on a public key in the public and private key pair, and obtaining a block chain account address corresponding to the public and private key pair through a corresponding code (Base 58, 16-system code and the like).
Root chain: the chain is created when the block chain link point is started, and the creation wallet, the number of certificates and the chain name are initialized and fixed as root. The Root chain may be upgraded to any consensus mechanism, including but not limited to POW, POS, etc., via a voting mechanism.
And (4) service chaining: the chain generated from the root chain needs to consume a certain number of root chain certificates, money packets created by the business chain, the number of certificates (circulated encrypted digital rights certificates) and the like.
Referring to fig. 1, fig. 1 is a block chain network construction method for facilitating expansion and node resource reuse according to an embodiment of the present invention. As shown in fig. 1, the method for constructing a blockchain network of the present embodiment includes the following steps:
s101: the subchain initiator determines a subchain BUSID name and the number of subchain created passage certificates, and creates a first blockchain account and a second blockchain account, wherein the first blockchain account is used for obtaining the passage certificates of the ROOT chain in the blockchain network.
In the embodiment of the invention, a link establishment initiator is in a preparation stage, the link establishment initiator firstly creates a block link account A, obtains a certain ROOT link certificate by using the account A, creates a sub-link ROOT account S, well selects the BUSID name of a sub-link, and determines the number of created certificates to be issued when the sub-link is created.
S102: and initiating a Gas transaction to a ROOT chain according to the first block chain account address, wherein the Gas transaction information comprises a link establishment secret key and is used for ensuring the safety of the Gas transaction.
In the embodiment of the present invention, an account address a (also referred to as a first blockchain account address) is used to initiate a transaction transfer to a designated transaction address G of the ROOT chain (G is a default account address for creating a subchain for Gas fee), for example: a counts out 100 and G incomes 100. The transaction information must contain a chaining secret, which is obtained by a random string str signed by the private key of the child chain root account S.
In the prior art, Gas transactions mainly have 2 types, one is a commission mode, that is, when a transaction initiator initiates a certain transaction, in addition to asset transfer of the transaction itself, some transaction commission is additionally attached. The extra transaction commission is given to the miners, who (who means the node) helps me to pack (i.e. keep accounts), and who is given. When the nodes are packaged, the transactions with high transaction fees are preferably selected to be packaged according to the ranking of the transaction fees in the transactions. The other is execution mode consumption, which mainly refers to intelligent contract Gas consumption, for example, an etherhouse, the intelligent contract needs to reserve a certain amount of Gas before execution, when each line of codes of the contract is executed by the EVM, a certain execution fee is deducted from a specified Gas account until the contract program is executed, and if the Gas account is left, the executed code is returned to a caller of the contract.
In the embodiment of the invention, the Gas transaction is a single payment execution action, and the transaction cost is not given to a specific packing node but to a chain operator. And the chain establishment initiating party pays the chain establishment Gas cost to the chain establishment operator. The Gas charging account is an account designated by a chain operator, the sub-chain creation program can check whether the account receives the charge paid by a chain establishment initiator, namely the Gas transaction, check information reserved in the Gas transaction by the chain establishment initiator after the detection, and then start the chain establishment program to create the sub-chain after the check is passed.
S103: and determining whether the subchain initiator submits a subchain creation request to the blockchain network or not according to the transaction result.
And after the transaction is successful, the sub-chain initiator requests to create the sub-chain, otherwise, the sub-chain creation request fails.
In an embodiment of the present invention, the creating the content of the child chain request includes: the name of the sub-chain BUSID, the number of the sub-chain generations of the testimony, the account of the second block chain and the public key thereof, the Gas transaction ID, the Gas consumption, the original string str of the build chain secret language and the description information of the sub-chain.
S104: and verifying the sub-chain establishing request, including verifying the sub-chain establishing parameters and verifying the link establishing password.
In an embodiment of the present invention, after receiving the request for creating the sub-chain, the blockchain network checks the link establishment parameter to see whether the link establishment parameter meets the requirement, and meanwhile, searches the Gas consumption transaction by using the Gas transaction ID to obtain the link establishment secret in the Gas transaction, and verifies the link establishment secret and the original string str of the link establishment secret by using the public key of the sub-chain root account S.
S105: and after the verification is passed, the block chain network creates a sub chain creation block according to the link creation information, wherein the link creation information comprises a second block chain account, the number of sub chain creation passphrases and a sub chain BUSID.
In an embodiment of the invention, after the creation block of the sub-chain is completed, the creation block includes the sub-chain BUSID, and a sub-chain is derived subsequently, so that a block chain with a tree structure is formed, and partition and fragmentation of the block chain are realized. In this embodiment, the sub-chains generated by the method are parallel, so that the blockchain can be infinitely expanded, thereby improving the overall performance of the blockchain.
In the invention, the service sub-chains are created based on the BUSID identification, the sub-chains are logically isolated, each chain can share the node capability, the partition and the fragmentation processing of the block chains can be conveniently carried out, and the support is provided for the TPS customization of the specific service chain; creating the sub-chain in a Gas transaction mode, so that the creation of the service sub-chain is convenient, simple and controllable; and ensuring the safety of the link establishment based on a link establishment secret language safety mechanism.
Referring to fig. 2, the present invention provides a conveniently-expanded blockchain network system with node resource reuse, including a plurality of sub-chains and a plurality of blockchain nodes, wherein the plurality of blockchain nodes are divided into: the accounting node is used for joining the blockchain network system, participating in transaction consensus, recording transaction information and storing the transaction information in a block falling disk manner; the monitoring/observer node is used for joining the blockchain network system, receiving the network transaction information but not participating in transaction consensus, and recording the consensus transaction information and storing the consensus transaction information in a blockchain manner;
the light node is used for generating a blockchain account without adding the blockchain network system, and initiating transaction inquiry and blockchain inquiry to the blockchain network system; the plurality of sub chains and the plurality of block chain nodes are divided into a plurality of virtual block chain networks, and whether block chain link points participate in transaction consensus or not is determined according to sub chain BUSID names in different virtual block chain networks, so that accounting nodes are determined; and authorizing the accounting node processing by other block nodes which do not participate in transaction consensus in the sub-chain.
In one embodiment of the present invention, a schematic diagram of a chain network system is provided, and a block chain network is formed by 14 block chain link points. Generally, the block link points may be distributed in one sub-chain, or in a plurality of sub-chains, specifically, 14 nodes are distributed in different sub-chains A, B, C and divided into 3 virtual areas, where five nodes a1, a2, A3, a4, a5 on the sub-chain a judge that they participate in the consensus protocol according to the BUSID of the sub-chain, and form the consensus node of the sub-chain a. Therefore, if the BUSID in the blockchain network is the transaction of the sub-chain a, the transaction consensus is performed only in the consensus nodes in the sub-chain a (of course, the sub-chain a also has nodes other than a1, a2, A3, a4, and a 5), and all other nodes in the sub-chain a delegate the transaction to the consensus nodes for processing (including the consensus blocks, queries, and the like). Similarly, if the BUSID in the blockchain network is a transaction for subchain B, then the transaction consensus is only performed in subchain B consensus nodes (B1, B2, B3, B4, B5), and if the BUSID in the blockchain network is a transaction for the ROOT chain and subchain C, then the transaction consensus is performed in these nodes in the middle (C1, C2, C3, C4). That is to say, in the blockchain link network system of the present invention, the nodes of each sub-chain can perform certain division of work, and by using the BUSIDs of the sub-chains, it is possible to logically distinguish each service chain, and also to share blockchain link points and also to operate at their own blockchain link points, thereby conveniently and flexibly supporting partitioning and fragmentation, improving the TPS capability of the system, and satisfying the needs of different service scenarios.
In the embodiment of the invention, the block chain links and the nodes are connected by a P2P communication method, specifically, after a sub-chain is created, each chain also has a BUSID, so that all data of the type of chain is responsible for the BUSID-named communication group, and the data of the type of chain is not automatically forwarded to the corresponding BUSID communication group to be processed after the communication group receives the request information of the chain. And, according to the business needs, corresponding communication group services between the nodes can be started and stopped dynamically.
Specifically, each billing node is activated and joined to a public service group, where each billing node is in peer-to-peer communication. After each sub-chain is created, the blockchain network creates a sub-chain communication service group for the sub-chain, namely a BUSID communication group. The sub-chain communication service group is a logical communication group on the public service group, nodes participating in sub-chain identification can join the sub-chain communication service group, related communication in the sub-chain identification nodes can communicate in the sub-chain communication group, and communication among different sub-chain nodes can communicate through the public service group. According to the invention, the BUSID communication group is arranged, so that the communication of the bookkeeping nodes participating in the consensus is controlled in the sub-chain communication group, the communication range of the consensus node can be effectively controlled, the network flooding is avoided, and the response efficiency is improved.
In the embodiment of the invention, the plurality of sub chains and the plurality of blockchain nodes are divided into a plurality of virtual blockchain networks, and whether block link points participate in transaction consensus or not is determined according to sub chain BUSID names in different virtual blockchain networks, so that accounting nodes are determined; wherein, whether to participate in the transaction consensus is completed by adopting a consensus algorithm, and the consensus algorithm is as follows:
n is the number of online accounting nodes of the whole network, and each accounting node monitors all the online accounting nodes in real time through a network heartbeat mechanism;
p is the participation of the accounting node,
the initial value of P is 1,
m is the whole network transaction times recorded by the accounting node, and q is the consensus correct times recorded by the accounting node that the accounting point participates in accounting;
t is an algorithm adjusting parameter, wherein,
and setting according to actual business needs.
The longer the operation time is, the more loyalty is caused by the accounting nodes adopting the consensus algorithm; the higher the accuracy in the consensus accounting is, the more loyal the accounting nodes are; accounting nodes belonging to the same organization or individual, and in the event of consensus conflicts, the calculation weight will be reduced in equal proportion. The method avoids the achievement of the accounting consensus through a resource consumption mode, and divides a service partition mode through the consensus algorithm mechanism to deconstruct a network model, thereby improving the TPS and the expandability of the system.
Fig. 3 is a schematic diagram of a terminal device according to an embodiment of the present invention. As shown in fig. 3, the terminal device 6 of this embodiment includes: a processor 60, a memory 61 and a computer program 62, such as a program for credit financing, stored in said memory 61 and executable on said processor 60.
