gRPC Lays the Foundation for Smarter Data Access on Sui

Sui has rolled out full beta support for gRPC APIs across its Full Nodes, revolutionizing how developers access and interact with blockchain data. With performance and developer experience as key priorities, the new implementation replaces traditional JSON-RPC with advanced features like binary serialization, real-time streaming, and standardized schema definitions. This strategic upgrade marks a broader shift towards building modular, push-based data infrastructure to power highly responsive and scalable Web3 applications.

Key Ideas

gRPC becomes the backbone for Sui data access: Features include strong typing, efficient serialization, real-time streaming (SubscriptionService), and uniform schemas across services.
JSON-RPC phase-out begins: gRPC is positioned as the canonical API, optimizing indexing, application responsiveness, and backend reliability for future Sui dApps.

Why It Matters?

Sui’s gRPC upgrade is the foundation for enterprise-grade blockchain utility. Investing in scalable, real-time data pipelines through Sui enables verticals like logistics, finance, and IoT to evolve into Web3-native ecosystems with confidence and performance at their core.
