Detailed ways

In order to facilitate the construction of the technical means, creation features, achievement goals and effects of the present invention, the present invention will be further described below with reference to specific embodiments.

As shown in Figure 1-4, a blockchain-based service ecological supply alliance online service system includes ecological supply communication network, blockchain underlying blockchain open source platform, control terminal, payment platform, data storage server and Data processing server, wherein the data processing server establishes data connections with the control terminal, payment platform, and data storage server respectively through the state supply communication network. There are several control terminals and payment platforms, and each control terminal and payment platform are connected in parallel. Blockchain The underlying blockchain open source platform is embedded in the data processing server, and at the same time, the underlying blockchain open source platform of the blockchain pushes mapping programs and system control client programs in each control terminal, payment platform, and data storage server.

It is emphasized that the underlying blockchain open source platform adopts the HyperledgerFabric open source framework structure to build the BaaS underlying blockchain technology; it is divided into six layers:

Application layer: Support VUE, Bootstrap and other mainstream front-end technology architectures, including eight modules: electronic files, commodity traceability, financial transactions, logistics services, inventory management, settlement and reimbursement, invoice authentication, and monitoring operation and maintenance;

Interface layer: Provide software development tools such as service API and SDK;

Application support layer: adopt multi-level encryption mechanism, introduce smart contract engine to write, set up multi-level encryption mechanism, AMOP, CNS, multi-ledgers, privacy protection, blockchain governance, data management and smart monthly protection including EVM and Precompiled execution engine;

Protocol core layer: Adopt PBFT consensus algorithm and P2P network transmission protocol, which can be reviewed by everyone through the consensus mechanism, and use the timestamp mechanism to trace user behavior, ensuring the openness and transparency of the system;

Physical layer: support the deployment of multiple environments such as physical machines and cloud platforms;

Business expansion layer: Provides a variety of deployment forms, based on the popular kubernetes technology, provides a scalable blockchain platform; at the same time, expanding the system operation and maintenance tools can summarize the data provided by all parties, and use the integrated data to make it easier for each business user to carry out the system. analysis, etc.

In this embodiment, the application layer further includes eight modules: electronic files, commodity traceability, financial transactions, logistics services, inventory management, settlement and reimbursement, invoice authentication, and monitoring operation and maintenance. And link suppliers, manufacturers, Internet e-commerce, distributors, channels, banks, etc., to achieve credible information sharing of each supply chain in the alliance chain.

In this embodiment, the settlement and account book is divided into two parts: block data and state data; block data is stored in series in a block chain manner, each block points to the parent block, and the state data is a key-value pair The form is stored in the database, the transaction in the block will change the state data, and each transaction will perform a state transition.

It is important to note that the open source platform of the blockchain underlying blockchain also adopts a pluggable consensus mechanism, DPoS algorithm, fault-tolerant algorithm in the field of PBFT distributed computing, and Raft algorithm, among which:

Pluggable consensus mechanism: The consensus mechanism can ensure that each node in the blockchain system agrees on data, process and behavior under preset rules, and achieves the consistency and correctness of ledger data on different ledger nodes. And historical data cannot be tampered with. The consensus mechanisms supported by the blockchain BaaS platform include DPoS (Delegated Proof of Stake), PBFT, and Raft; different consensus mechanisms can be used for different business needs;

DPoS algorithm: Delegated Proof of Stake is based on the PoS (Proof of Equity Mechanism) algorithm, which enables everyone to choose someone who can represent their own interests to participate in the battle for bookkeeping rights, so that multiple small shareholders can vote for their own proxies , to protect their own interests. The DPoS algorithm can guarantee security in any network environment and can prevent the collusion of minority groups in voting;

Fault-tolerant algorithm in the field of PBFT distributed computing: Byzantine Fault Tolerance (BFT) is a kind of fault-tolerant technology in the field of distributed computing. Byzantine assumes that computers and networks may behave unpredictably due to hardware errors in the network, network congestion or disruption, and malicious attacks. In this case, ensure the consistency and correctness of the entire network data;

In practice, it is theoretically feasible but lacks practicality due to the original Byzantine fault-tolerant system. Practical Byzantine Fault Tolerance (PBFT) reduces the operational complexity of Byzantine agreement. PBFT is a state machine replica replication algorithm, that is, a service is modeled as a state machine, and the state machine is replicated in different nodes of a distributed system. Each copy of the state machine holds the state of the service and also implements the operation of the service. The set of all replicas is represented by the capital letter R. Usually, it is assumed that the number of faulty nodes is m, and the total number of service nodes is |R|=3m+1, where m is the maximum number of replicas that may fail;

Raft algorithm: In the practical scenario of distributed systems, its assumptions do not need to consider Byzantine faults, but only deal with general crash faults. In this case, it would be more efficient to adopt a protocol such as Paxos. Raft is a simplified variant of the Paxos protocol. In the blockchain system, the process of using Raft to achieve bookkeeping consensus can be described as follows: first, a leader is elected, and then the leader is given full power to manage bookkeeping. The leader receives the accounting request from the client, completes the accounting operation, generates a block, and replicates it to other accounting nodes. Having a leader simplifies the management of bookkeeping operations. For example, the leader can decide whether to accept new transaction records without considering other accounting nodes. The leader may fail or lose contact with other nodes. At this time, the system will elect a new leader.

In this embodiment, the data storage server and the data processing server are both directly stored in the block on the chain based on the smart contract, and the file fingerprint is stored in the block on the chain by using the file data through hash digest. data storage structure;
