SDChain (SDA)

SDChain Alliance, established in Canada, makes full use of blockchain for IoT (Internet of Things) applications. SDChain intends to promote and contribute towards the formation of a new infrastructure that combines the IoT and blockchain technology. The objective of this new infrastructure will be to improve the efficiency of interaction between users, physical objects and digital asset resources.

SDChain allows data producers and data users to exchange digital assets within an open partnership ecosystem, based on globally standardized IoT six-domain model.

SDChain is an acronym for SixDomainChain, a native blockchain which will be integrated with IoT. SDA (Six Domain Assets) is the native token that will act as digital asset. Users will be able to exchange SDA for services and transactions within the SDChain platform. The SDChain team also intends to use SDA as an incentive to encourage the maintenance of the ecosystem.

SDChain intends to attract different business industries by providing core functions for DApps (Distributed Applications) developed by those industries. Some of the core functions include:

• Management of digital credit
• Data storage on blockchain
• Authentication and authorization
• Data query
• Development of Smart Contracts using Lua

Some of the industries that SDChain intends to improve with its platform include:

• Agriculture
• Textile
• Energy
• Healthcare
• Smart Home
• Smart Parking

SDChain has very elaborate structure and it’s pretty hard to get the inner workings of it. The infrastructure has very niche use cases and it’s unlikely we’ll ever see it adopted at a wide scale.

There is no part to explain why the project would specifically link IoT with the blockchain. In terms of token economy, there was no apparent mechanism to incentivize ecosystem participants.

Also, it is based out of China, which has been known to be quite an uncertain country when it comes to cryptocurrency regulation.

Functional views describe the typical functional components of the SDChain system through a hierarchical structure of four horizontal and four vertical layers, including user layer, service layer, base layer and cross-layer functions.

• User layer: User functions, Business functions, and Management functions.
• Development: IDE, SD, Test Management and Construction management.
• Service layer: Access management, Nodes management and ledger management.
• Operation: Strategy management, Abnormality management, Delivery management and cross-chain service management.
• Core layer: Consensus, Bookkeeping, Smart contract, encryption, Digital signature and Scheduled services.
• Security: Authentication and identity management, Authorization and security policy management and Privacy protection.
• Base layer: Storage, Communication Computation, and P2P network.
• Governance and audit: Governance support and Audit implementation.

SDChain is designed to address the various requirements and business needs from different companies and users with the IoT Six-Domain Model, such as IoT business users, IoT device users, IoT service platform users, IoT operation, regulatory platform users, third-party business cooperation users, property owner users and others.

It will optimize in depth for current blockchain technology, specifically in sub-fields of digital assets issuance, credit of user identity management, P2P communication, encryption algorithm, consensus algorithm, smart contracts, cross-chain smart contract models, market consensus incentives, decentralized DApps and fast access to new business, to ensure the benign, fast and sustainable development of SDChain ecosystem.

By doing so, it will promote the coexistence of token, blockchain, and IoT technologies, achieve efficient circulation and transition of digital assets credit, therefore SDChain will become a universal benchmark to promote the real social development through the combination of IoT and Blockchain.
