KEY TAKEAWAYS
- Sui launches full beta support for gRPC APIs on its Full Nodes, enhancing data infrastructure capabilities.
- gRPC offers a faster, more expressive method for interacting with the Sui blockchain, replacing the legacy JSON-RPC.
- The beta release introduces new services like SubscriptionService, enabling real-time data streaming for developers.
- This initiative aims to reimagine blockchain data serving, with gRPC becoming the canonical Full Node API.
Sui has announced the launch of full beta support for gRPC APIs on its Full Nodes, marking a significant step in its mission to provide a world-class data infrastructure. This beta release is designed for testing and preparing applications for future production readiness, with potential changes based on user feedback. The introduction of gRPC aims to offer a faster, more expressive, and future-ready method for interacting with the Sui blockchain.
gRPC, a high-performance, schema-driven communication protocol, is intended for modern distributed systems. It is set to become a foundational component of Sui’s long-term data serving strategy. Compared to the legacy JSON-RPC, gRPC provides strong typing and client generation support across multiple programming languages, compact binary serialization via Protobuf, and real-time data streaming capabilities.
New Services and Capabilities
The beta release of gRPC introduces a comprehensive set of Full Node services to support various developer and infrastructure needs. These include the MovePackageService for introspecting deployed Move packages, the SignatureVerificationService for pre-verifying digital signatures, and the TransactionExecutionService for submitting signed transactions to the network. Additionally, the LedgerService allows querying of objects, transactions, checkpoints, epochs, and system state, while the LiveDataService fetches active state data like balances and simulates transactions.
One of the standout features of this release is the new SubscriptionService, which enables server-side streaming APIs for onchain activity. This service allows developers to subscribe to executed checkpoints and fetch details using other batch API services. The streams are gapless and ordered, ensuring that indexers, bots, wallets, and explorers can stay synced in real-time without the need for polling.
Implications for Developers and Infrastructure
The introduction of gRPC APIs on Sui Full Nodes is poised to enhance the way blockchain data is accessed and utilized. Developers can build responsive applications with real-time data, simulate and execute transactions, and track live user or app activity. Exchanges can maintain fast, reliable infrastructure by rapidly executing and verifying transactions and accessing both recent and historical data.
Indexers and data providers can power high-performance APIs and dashboards by combining live subscriptions with batch queries. Meanwhile, RPC providers and node operators can serve modern developer needs with fast serialization, real-time streaming, and typed, maintainable interfaces built for scale.
This release is part of a broader initiative to reimagine blockchain data serving and consumption on Sui. The data serving guide outlines a vision that includes a clear separation between raw data (gRPC) and rich, derived data (GraphQL), support for real-time streaming alongside batch APIs, and a next-generation indexer framework. As Sui phases out JSON-RPC, gRPC will become the canonical Full Node API, offering lower latency and richer semantics.
