📄️ Exposing blockchain data
While this lab utilizes the MultiversX network to demonstrate practical implementations, the fundamental principles of data exposure and querying—such as the distinction between direct VM interaction and off-chain indexing—are applicable across most blockchain architectures.
📄️ Scaling your APIs
When building a production-grade dApp or backend service on MultiversX, relying solely on direct calls to the public API is rarely sufficient. As your user base grows, you will encounter performance bottlenecks and restrictions.
📄️ Practice
In this session, we will demonstrate how a single caching layer can protect your application from Rate Limits and allow it to scale to hundreds of concurrent users using NestJS and Redis.
