区块链存证系统解决方案 Blockchain Certificate Storage System Solution
1 方案背景 Scenario Background
As a subversive technology, block chain is leading a new round of technological and industrial changes, and is expected to become the "source" of technological innovation and mode innovation, and promote the change from "information Internet" to "value Internet". Block chain, as an integrated innovation of point-to-point network, cryptography, consensus mechanism, intelligent contract and other technologies, provides a trusted channel for information and value exchange in untrusted networks.
At present, China's block chain technology continues to innovate, and the block chain industry has initially formed. It has been rapidly applied in supply chain finance, credit information, electronic data certification, energy trading, product traceability, copyright trading, digital identity and other fields.
Block chain can record the whole process and the whole transaction data, and all the data are shared by all the nodes in the chain. It realizes the truthfulness, trustworthiness and non-tampering of electronic data storage, makes the information in network space more transparent and traceable, and can check the data consistency in real time, break the information island and realize information sharing. In addition to the transaction subject, some regulatory departments can join the block chain as nodes, real-time monitoring of other user nodes'transaction information, to prevent the occurrence of risk events.
Block chain intelligent contract is an event-driven, stateful, multi-party recognized program that runs on block chain and can automatically process assets according to preset conditions. It can automatically monitor network transactions and achieve more automated and intelligent business development and supervision.
2 建设目标 Construction Goal
We will build an honest block chain to provide data warehousing and inquiry services for various businesses, and ensure the reliable development of big data credit reporting, supply chain finance, photovoltaic, integral, shopping mall, payment and other businesses. Provide interfaces to support large data credit, supply chain finance, photovoltaic, integral, mall, payment and other business, including block chain deposit, inquiry, authentication, asset transfer, integral cash in and out, credit application, financing credit, commodity trading, photovoltaic trading, payment settlement and other interfaces.
It provides the functions of creating, generating, running and configuring intelligent contracts, including payment and settlement intelligent contracts, financing credit intelligent contracts, transaction intelligent contracts, dispatching intelligent contracts, etc.
Provide honest block chain system support to protect the legal rights and interests of all participating methods.
3 总体技术路线 Overall Technical Route
Block chains are deployed in three ways: public chains, private chains and alliance chains.
Public chains refer to the block chains that are open to all people in the world. Everyone can become a node in the system to participate in accounting. They usually combine incentive mechanism and encrypted digital verification to achieve consensus on transactions.
Alliance chain refers to the block chain in which several organizations participate in accounting, i.e. the members of the alliance reach consensus through mutual trust among multiple centers. The data of federation chain only allows members of the system to read, write and send transactions, and record transaction data together.
Private chains are not decentralized, but they are distributed. The central controller establishes the scope of members who can participate in and validate transactions.
Compared with public chains, alliance chains have more advantages in high availability, high performance, programmability and privacy protection. They are considered as "partially de-centralized" or "multi-centric" block chains. Alliance chain simplifies the number of nodes, makes the system run more efficiently and cost less, and the number of transactions that can be confirmed in a unit time is much larger than that of public chain.
Through the above analysis, the scheme uses block chain technology to build "Integrity chain" alliance chain.
4 诚信链建设方案 Integrity Chain Construction Scheme
Integrity chain uses block chain technology to build up user enterprises, courts, procuratorates, judicial appraisal centers, third-party electronic certification agencies, banks and departments.
