Review

SDChain Alliance, established in Canada, makes full use of blockchain for IoT applications. SDChain envisions that IoT data from the physical world, should be shareable via a fast and cost-effective digital blockchain network where data producers and data users conduct digital asset exchange, within an open partnership ecosystem, based on globally standardized IoT six-domain model.

How it works

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.

Functionality

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.

Problems:

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.

Conclusion:

Let’s summarize, SDChain is a public blockchain ecosystem for the world’s first decentralized data trading, according to white paper. This ecosystem integrates blockchain platforms with the six domains in IoT. While there are some questions around it, it’s a relatively new project and we shouldn’t be quick to write it off.

Pros

  • Limited

Cons

  • No direct backing (asset, profits, commodity)
  • Possible county based regulations
  • Limited exchanges and volume.
