Substreams Enhances Solana (SOL) Data Access with Fork Awareness

Solana (SOL), known for its high-speed blockchain capabilities, poses unique challenges for developers, especially in accessing and interpreting on-chain data. According to The Graph, Substreams has launched a solution to streamline Solana account data retrieval, offering enhanced data streaming capabilities with fork awareness.

The Challenges of Solana's Architecture

Solana's architecture, designed to execute thousands of transactions per second independently across accounts, separates transaction execution from account state. While this design boosts performance, it complicates data access and historical data interpretation for developers. Critical data such as token balances and NFT metadata are stored in accounts, detached from transaction or block data, making reliable data querying a complex task.

Addressing Fragmented Data Issues

Developers face several hurdles due to Solana’s fragmented data model:

• RPC Limitations: Public RPC providers often struggle with the load, resulting in slow, costly data queries.
• Lack of Historical Data: Most streaming services focus on real-time data, lacking historical depth unless developers maintain their own infrastructure.
• Re-org Challenges: Frequent re-orgs in Solana's fast-paced environment require self-managed tools, often leading to inaccurate data reporting.

Substreams: A Comprehensive Solution

Substreams addresses these issues by providing a filterable, fork-aware stream of Solana account changes. Key features include:

• Bypassing RPC Bottlenecks: Utilizing gRPC, Substreams streams Solana block data efficiently, avoiding RPC rate limits.
• Historical Data Access: Offers up to 90 days of historical account change data, facilitating analytics and system syncing.
• Automatic Fork Awareness: Ensures data consistency with the canonical chain by tracking Solana re-orgs and accounts.
• Integrated Decoding: Provides decoded account changes for major Solana programs, eliminating the need for custom parsing.

Real-World Application: Helium Protocol

Helium, a prominent user of Substreams, leverages its capabilities to enhance user experience by tracking real-time account state changes, reducing redundant infrastructure and improving reliability.
