How Blockchain-as-a-Service Is Driving the New Digital Infrastructure

Blockchain and cloud computing are converging to form a new strategic layer called Blockchain-as-a-Service (BaaS). The author argues that, like cloud computing a decade ago, BaaS is still in its early stage but is rapidly becoming a core component of the national "new infrastructure" agenda alongside cloud and AI.

For enterprises focused on application development, BaaS eliminates the need to master low‑level blockchain protocols or rebuild foundational components. Instead, they can consume a managed service and concentrate on business logic.

Cloud‑chain integration is presented as a key concept: cloud resources (IoT, big data, AI) are layered onto blockchain to solve real‑world problems while reducing development cost and complexity.

The Tencent Cloud TBaaS platform, launched in 2017, exemplifies this approach. Its architecture is described in three layers:

Infrastructure layer : underlying cloud servers, networking, storage, and automated operations.

Platform layer : enhanced Hyperledger Fabric engine, full lifecycle network management, governance (alliance, network, sub‑chain), monitoring, and developer tools such as an online smart‑contract IDE with templates, debugging, compilation, and execution support.

Application layer : industry solutions including trusted notarization, electronic invoicing, supply‑chain finance, smart city platforms, construction blockchain, and charitable applications.

TBaaS also supports flexible multi‑enterprise node interconnection across clouds and regions, and a cross‑chain communication scheme that breaks the isolation of individual blockchains.

A concrete case study illustrates the value of BaaS: a warehouse‑receipt pledge financing solution for a steel‑trading company in Foshan. From March 2019 to November 2020, the system recorded 85,000 tons of steel, onboarded 75 new clients, increased financing volume by 50% year‑over‑year, and surpassed ¥3 billion in loans.

The solution combines blockchain for immutable receipt digitization, IoT sensors for real‑time asset monitoring, and AI video analysis for post‑loan risk control, ensuring the authenticity and safety of pledged goods.

Overall, the article concludes that BaaS, backed by cloud infrastructure and auxiliary technologies, is becoming a foundational service for digital transformation, enabling enterprises to adopt blockchain with lower cost, higher reliability, and greater scalability.
