Detailed Description
In order to facilitate the implementation of the technical means, creation features, achievement of the purpose and the efficacy of the invention, the invention is further described below with reference to specific embodiments.
The block chain-based service ecological supply alliance online service system comprises an ecological supply communication network, a block chain bottom block chain source-opening platform, an operation terminal, a payment platform, a data storage server and a data processing server, wherein the data processing server is in data connection with the operation terminal, the payment platform and the data storage server through the ecological supply communication network, the operation terminal and the payment platform are multiple, the operation terminal and the payment platform are connected in parallel, the block chain bottom block chain source-opening platform is embedded in the data processing server, and meanwhile the block chain bottom block chain source-opening platform pushes a mapping program and a system operation client program in the operation terminal, the payment platform and the data storage server respectively.
The method mainly comprises the following steps that (1) a BaaS bottom layer block chain technology is built by adopting a HyperLegendric fabric open source frame structure on the bottom layer block chain open source platform; and has a six-layer structure:
the application layer supports mainstream front-end technical architectures such as VUE (maintenance utility), Bootstrap and the like and comprises eight modules of electronic archives, commodity traceability, financial transactions, logistics services, inventory management, settlement and account reporting, invoice authentication and monitoring operation and maintenance;
interface layer: providing software development tools such as a service API and an SDK;
applying a support layer: adopting a multi-stage encryption mechanism, introducing an intelligent contract engine for compiling, setting the multi-stage encryption mechanism, AMAP, CNS, multi-account book, privacy protection, block chain management, data management and an intelligent quota monthly execution engine comprising EVM and Precompiled;
protocol core layer: the PBFT consensus algorithm and the P2P network transmission protocol are adopted, all people can review the system through a consensus mechanism, and the user behavior is traced by utilizing a timestamp mechanism, so that the public transparency of the system is ensured;
physical layer: supporting the deployment of a physical machine, a cloud platform and other multi-environment;
and a service expansion layer: providing a plurality of deployment forms, and providing an extensible block chain platform based on the popular kubernets technology; meanwhile, the extended system operation and maintenance tool can summarize data provided by all parties, and the integrated data is utilized to facilitate operation such as system analysis of all service users.
In this embodiment, the application layer further includes eight major modules, namely, an electronic archive, a commodity tracing source, a financial transaction, a logistics service, inventory management, settlement and accounting, invoice authentication, and operation and maintenance monitoring. And the suppliers, manufacturers, Internet e-commerce, distributors, channels, banks and the like are linked together, so that the information of each supply chain in the alliance chain can be truthfully shared.
In this embodiment, the settlement and account book is divided into two parts, namely block data and state data; the block data are stored in series in a block chain mode, each block points to a parent block, the state data are stored in a database in a key value pair mode, transactions in the blocks change the state data, and the state transition is carried out once each transaction is executed.
It is important to explain that the block chain bottom layer block chain open source platform additionally adopts a pluggable consensus mechanism, a DPoS algorithm, a fault-tolerant algorithm in the PBFT distributed computing field, and a Raft algorithm, wherein:
a pluggable consensus mechanism: the consensus mechanism can ensure that each node in the block chain system agrees with data, flow and behaviors under a preset rule, and the consistency and correctness of the account book data on different account book nodes are realized. And the historical data is not falsifiable. The common recognition mechanism supported by the block chain BaaS platform is DPoS (delegation rights and benefits certification), PBFT and Raft; different consensus mechanisms can be adopted for different service requirements;
DPoS algorithm: the entrusting equity certification is based on a PoS (stock right certification mechanism) algorithm, and each person can select a person representing own interests to participate in the competition of the accounting rights, so that a plurality of small stockholders can select own agents by voting to guarantee own interests. The DPoS algorithm can ensure safety in any network environment and can prevent the condition of colluding and colluding votes of minority groups;
fault tolerant algorithm in the field of PBFT distributed computing: byzantine Fault Tolerance (BFT) is a Fault Tolerance in the field of distributed computing. Byzantine assumes that hardware errors, network congestion or interruptions, and malicious attacks occur in the network, and that computers and networks may behave unpredictably. In this case, the consistency and correctness of the data of the whole network are ensured;
in practice, it is theoretically feasible but lacks practicality due to the original byzantine fault tolerant system. The operating complexity of the Byzantine protocol is reduced by a practical Byzantine fault tolerant system (PBFT), the PBFT is a state machine copy replication algorithm, namely, a service is used as a state machine for modeling, and the state machine performs copy replication at different nodes of a distributed system. The copies of each state machine preserve the state of the service and also enable the operation of the service. The set composed of all the copies is represented by using a capital letter R, and the number of fault nodes is generally assumed to be m, the number of the whole service nodes is | R | =3m +1, and m is the maximum number of the copies which are possibly failed;
the Raft algorithm: in a practical scenario of a distributed system, the assumption condition does not need to consider byzantine faults, but only deals with general crash faults. In this case, it is more efficient to employ a protocol such as Paxos. Raft is a simplified version of the Paxos protocol. In a blockchain system, the process of using Raft to achieve billing consensus can be described as follows: a leader is elected first, and then the leader is given full rights management accounting. And the leader receives the accounting request from the client, completes the accounting operation, generates a block and copies the block to other accounting nodes. Having a leader simplifies the management of accounting operations. For example, the leader can decide whether to accept the new transaction entry without regard to other accounting nodes, the leader may fail or lose contact with other nodes, and the system may elect a new leader.
In this embodiment, the data storage server and the data processing server both adopt two types of data storage structures that are directly stored in the blocks on the chain based on the intelligent contract and store the file fingerprints in the blocks on the chain in a hash digest mode by using the file data;
meanwhile, the ecological supply communication network comprises a cross-chain interaction mechanism, and the cross-chain interaction mechanism realizes the information and value cross-chain generalization between homogeneous and heterogeneous chains through a cross-chain contract on the chain and a cross-chain service under the chain.
