An important prerequisite for the development of the digital economy is to accelerate the construction of new infrastructure. Under the background of "new infrastructure", promoting digital industrialization and industrial digital upgrading has become the consensus and direction of efforts of the entire industry. The blockchain, with its characteristics of decentralization, non-tampering, and trust transmission, has become an indispensable underlying technology in the "new infrastructure". In the face of the booming digital industrialization and industrial digitalization process, blockchain technology needs to carry a larger scale of applications, more business scenarios, and wider industry participation, which puts forward higher requirements for the underlying technology of blockchain.
At the same time, in order to actively explore the integration and development of the two sides of the strait, promote cross-strait and international economic, trade and cultural exchanges, and strengthen cross-strait and global business cooperation and win-win cooperation, the construction is guided by the China Industrial and Commercial Cooperation International Committee and cooperates with the International Science and Technology Cooperation Committee of the China Technology Market Association and Beijing Peili. Vocational College, Digital China Research Institute (Fujian), Fujian Provincial Property Rights Exchange Center, France-China Exchange Promotion Association, Fujian Provincial Federation of Enterprises and Entrepreneurs, Fujian Provincial Blockchain Association, Entropy Chain Technology (Fujian) Co., Ltd. and many other authorities Initiated jointly by institutions and units, Entropy Chain Technology (Xiamen) provides technical operation support to build a new generation of blockchain underlying technology service platform - "Strait Chain".
Straits Chain independently develops the "one core and two wings" blockchain architecture, which consists of "core chain", "open permission chain" and "open consensus chain". Developers can quickly and flexibly build blockchain basic services according to different usage scenarios .
Among them, the "core chain" serves as the basic anchor point of platform trust to realize the overall supervision and governance of the Straits Chain. The supervisory committee composed of the initiators of the Straits Chain jointly supervises and governs the operation and daily affairs of the Straits Chain through the core chain. At the same time, the core chain provides basic blockchain services such as data cross-chain, oracle, and privacy protection.
"Open permission chain" and "open consensus chain", under the premise of accepting the supervision of "core chain", are respectively customized for enterprise application scenarios with multi-organization and complex security access control, and flexible and brisk consumer application scenarios. It facilitates the flexible development, deployment, and application of different blockchain application scenarios, and supports low-cost multi-chain expansion.
Straits Chain also provides a self-developed "licensed IPFS storage network" to realize decentralized storage of off-chain data, data confirmation, privacy protection and permanent storage .
The overall technical framework of the Straits Chain is as follows:
Strait Chain Technology Framework Diagram
From the technical framework diagram, it can be clearly seen that Straits Chain is in order from bottom to top: file service layer, blockchain layer, service provider layer and application layer.
File service layer: Contains 3 major modules (IPFS contract module, light node access terminal and heavy node storage network), and integrates the licensed IPFS storage network to provide data support for the blockchain layer and realize the decentralization of files Persistent storage, rights management and version management. At the same time, various types of blockchain application data can be saved, for example: storing the original data of NFT in the IPFS network to achieve permanent data storage, which cannot be changed, is open and transparent, and can be queried.
Blockchain layer: It is the core part of the entire Straits Chain, responsible for various core tasks including: on-chain governance, data supervision, contract review, billing management, etc. The blockchain layer consists of the core chain, the open consensus chain, the open permission chain, these three chains and the external connection bridge.
The core chain is the supervision center and trust anchor of the blockchain layer. The data on the chain of the open consensus chain ZONE and the open permission chain ZONE will be regularly anchored to the core chain, so that the core chain can supervise the data on the sub-chain and prove the validity of any transaction. , each sub-chain can also complete cross-chain through the core chain.
The open consensus chain ZONE mainly meets the application development needs of small and medium-sized enterprises (to B) or consumers (to C). The data is open and transparent, and everyone can query and browse the data through the blockchain browser. It has a built-in SC-Runtime virtual machine, which is compatible with EVM, supports the operation of Solidity smart contracts, and provides a wealth of development libraries and developer tools to facilitate developers to develop applications and provide services on it. In addition, the open consensus chain ZONE can deploy multiple chains according to business needs, so that it has endless scalability and solves the problem of TPS limitations.
The open licensed chain ZONE mainly meets the needs of the government (to G) or industry alliances to use the chain. The data on the chain can be supervised, and you can choose whether to open it to the outside world according to the business situation. It adopts Fabric's alliance chain architecture, and nodes need to apply for certification before joining the open permission chain ZONE. Supports Go and Java smart contracts, which can be deployed locally in the enterprise, hosted or shared, flexible and convenient. It also integrates a visual blockchain management and monitoring platform, a trusted identity system, and privacy protection functions, reducing the threshold for business development and use costs of the alliance chain.
The external connection bridge consists of a cross-chain HUB and an oracle. The cross-chain HUB integrates the SBI interface, which can complete cross-chain interaction with homogeneous or heterogeneous blockchains. Oracles include centralized oracle machines and decentralized oracle machines. The centralized oracle machine adopts the organization's digital certificate and signature technology, and introduces off-chain data provided by intelligent centralization, such as degree certificates, real estate certificates, etc., and the decentralized oracle machine uses a game-based consensus network to introduce decentralized off-chain data. Data such as weather, prices, game results, etc.
Service provider layer: abstractly encapsulates a series of service interfaces, including wallets, blockchain browsers, SDKs in various languages, contract management, NFT interfaces, IPFS interfaces, third-party interfaces and other application development tools, providing enterprises and developers with Improved technical support and lowered the development threshold for developers.
Application layer: mainly the enterprise application service market, which provides a series of smart contract applications and services developed by officials or developers. Enterprises can purchase various types of services or applications such as NFT, finance, games, certificate storage and traceability in the application service market for users to use. Developers can submit all kinds of developed smart contract applications to the application service market for sale and obtain continuous benefits.
Based on the strong underlying technical framework of Straits Chain, Straits Chain has highly secure privacy protection, supports multi-chain parallel expansion, distributed file storage, pro-supervision and easy governance, and meets diverse business needs and other technical advantages.
In terms of security, Straits Chain has implemented a complete set of security solutions, including: network access mechanism, file authority management mechanism, content review mechanism, key management mechanism, contract audit mechanism, etc. At the same time, Straits Chain supports a complete national secret algorithm system, supports homomorphic encryption and privacy calculation of zero-knowledge proof, and guarantees the privacy and security of data on the chain to the greatest extent.
