Rumble Fish Software Development

🎉 We've been awarded a $131,200 grant by Stellar Community Fund (Stellar Development Foundation).

The mission: build the block explorer Soroban deserves.

Soroban is where the most exciting development on Stellar is happening right now - DeFi, new token standards, complex smart contract interactions. But today, most of that activity is visible only in raw, unreadable formats. Developers, investors, and users deserve better.

We're building a Soroban-first Block Explorer that decodes on-chain data into clear, human-readable information, so anyone can see exactly what's happening on the network. Huge thanks to Stellar for trusting us to do a stellar job. 💪

Our CTO, Marek Kowalski, shares how we've transformed knowledge work at our company, and what's possible when you think beyond the obvious cases. Marek dives a bit deeper into two Claude use cases:

✅ An AI-powered lead generation system that we already use at Rumble Fish, processing job boards at scale and identifying opportunities that match our expertise in blockchain, ZKP, and AI. What used to take our sales team hours of manual work now happens automatically.
✅ Deploying Claude as a shared knowledge base in the cloud, where every refinement by one team member could benefit everyone instantly, creating a system that gets smarter through collective human insight.

This isn't about automation in the traditional sense. It's about AI that can actually think through problems, adapt to exceptions, and maintain consistent quality across thousands of cases. The real result? We're already operating at a different level of efficiency. 🚀

Our favourite author, Oskar, just wrote a technical deep dive on Zero-Knowledge Proofs on Stellar, and the timing couldn't be better. Stellar's upcoming X-Ray protocol upgrade is bringing BN254 support and native Poseidon hash functions to Soroban. For anyone building privacy-preserving applications, this changes the game.

What this means for developers:
🔹 Port existing Ethereum ZK apps without rewriting circuits
🔹 Dramatically lower gas costs for proof verification
🔹 Native host functions that handle heavy cryptographic operations at the node level.

Oskar breaks down the technical architecture - elliptic curves, host functions, and why Poseidon is optimized for ZK circuits in ways SHA-256 simply isn't.
If you're evaluating chains for ZK work, this is worth your time.

Guess who's back? Oskar returns with another insightful story - this time, we're learning about indexing blockchain data on Solana. He shows us two use cases and walks us through the entire indexing process. It's a must-read for blockchain devs struggling to tidy up enormous data flows.

Thank you, Oskar! 🚀

Our latest case study is live! Rumble Fish x Tari Labs

In just two months, we delivered a secure cross-chain bridge, Tapplet-verified frontend, automated miner flows, and gas optimizations. 3,000+ transactions later and nearly 500M XTM bridged, the results speak for themselves.

🔥 New case study just dropped.

We’re thrilled to share how Rumble Fish partnered with team to unlock DeFi for their native token. In just two months, we built and deployed:

✅ A fully-functional bridge from Tari → Ethereum (WXTM ERC-20)
✅ Tapplet-enabled frontend security (a first in production)
✅ Gas-optimized batching (cutting costs by ~40%)
✅ Automated miner “Mine-to-Exchange” flow for direct token issuance

With 3,000+ transactions processed and nearly 500m XTM bridged, this solution has truly opened the door for Tari into the Ethereum DeFi ecosystem.

🚀 zk-Rollups: From Blockchain Traffic Jams to Turbo Mode

Big thanks to Oskar, our amazing blockchain developer, for breaking down how zk-rollups are revolutionizing blockchain scalability! His latest post explains how these "scaling superheroes" bundle thousands of transactions off-chain, then prove everything with zero-knowledge cryptographic magic - making blockchains faster and cheaper without breaking a sweat. It's a must-read for anyone interested in scaling their Web3 business.

Key takeaways:
✅ Projects like zkSync, StarkNet & Polygon zkEVM are already delivering results
✅ zk-rollups = speed & compression (but privacy needs extra work)
✅ Growing ecosystem from pure scaling to identity & voting applications and beyond
