What can I help with?

In the ever-accelerating world of blockchain development, speed, scale, and access to real-time data can make or break an application. For developers building on Solana—the high-performance blockchain known for its lightning-fast transactions—those demands are even more acute. Enter Substreams, a cutting-edge data streaming framework that's quietly transforming the way developers interact with on-chain data.

Developed by StreamingFast and recently integrated into Solana's tooling ecosystem, Substreams offers something that traditional RPC endpoints and indexers never could: modular, composable, and parallelised access to real-time blockchain data—without the latency or overhead.

For Solana developers, this is a game-changer.

Traditionally, building decentralised applications that rely on historical or live data has required setting up and maintaining full nodes, writing custom indexing code, or relying on third-party APIs. These systems often buckle under Solana's throughput—more than 65,000 transactions per second—and its rapid block finality. Substreams solves this by allowing developers to define custom "modules" in Rust, which transform raw blockchain data into clean, usable streams. These modules can be combined and reused, reducing duplication and increasing speed dramatically.

More importantly, Substreams run in parallel, leveraging the scale of cloud and decentralised infrastructure to deliver blazing-fast performance. A DeFi protocol, for instance, can use Substreams to track every swap or liquidity pool update in near real time, then feed that into analytics, dashboards, or on-chain logic—all without maintaining a heavy backend.

The tooling is already being embraced across Solana's ecosystem. Projects in gaming, NFTs, and decentralised social are using Substreams to power live feeds, rankings, and user stats—all streamed directly from the blockchain itself.

Substreams also help bridge the gap between developers and decentralisation. By running on services like Pinax, developers no longer need to centralise data processing; they can build lighter, faster, and more open applications.

For Solana developers focused on performance, composability, and scale, Substreams isn't just another tool—it's becoming the new foundation. In a network built for speed, Substreams finally offers a data layer that can keep up.

As blockchain networks grow more complex and interconnected, a quiet revolution is taking shape in how data is analyzed and understood. At the center of this shift is Perplexity's Sonar API—a technology that represents a fundamental departure from traditional search paradigms.

"We've moved beyond the era of keyword matching and link retrieval," explains a senior developer at the company. "What users need is contextual understanding of blockchain activity across multiple networks, synthesized in real-time."

The Sonar approach stands apart from conventional search engines by focusing on answer synthesis rather than document retrieval. For blockchain applications, where data exists in siloed networks and disparate formats, this capability has proven transformative.

Industry analysts point to three distinctive capabilities that make Sonar particularly valuable for blockchain intelligence: its web-scale information retrieval, its ability to maintain factual accuracy even with rapidly changing data, and its natural language interface that democratizes access to complex blockchain metrics.

In practical applications, Sonar API acts as the connective tissue between raw on-chain data—streamed through technologies like Substreams—and the summarization capabilities of models like Google's Gemini. This creates what developers call an "intelligence pipeline" that flows from raw blockchain events to actionable insights.

The integration is especially powerful when examining cross-chain activity. As capital and data flow between Solana, Ethereum, and emerging Layer 2 networks via protocols like LayerZero, Sonar can track and contextualize these movements in ways traditional analytics platforms cannot.

"Before this integration, users had to manually piece together information from multiple block explorers, Twitter feeds, and developer forums," notes a DeFi researcher who requested anonymity. "Now they can simply ask natural language questions about complex cross-chain interactions and receive synthesized answers."

As blockchain ecosystems continue to evolve toward greater interconnectivity, technologies like Sonar that can seamlessly traverse network boundaries while maintaining coherent narratives about on-chain activity are likely to become essential infrastructure for both developers and users.

Early adopters can experience this capability by querying the platform about recent Solana developments, cross-chain transactions, or specific protocols—revealing a glimpse of how AI is reshaping our understanding of decentralized networks.
