Orb: A First‑Principles Block Explorer

In this episode of Talking Tokens, Jacquelyn Melinek speaks with Mert Mumtaz, Co-Founder and CEO of Helius. He shares his take on Solana evolving from earlier years with its NFT boom to the memecoin era and where it’s heading, as well as why better infrastructure, indexing and data readability were essential for scaling the network. Mert breaks down how Helius built the tools that make Solana legible, why transparency actually reinforces the need for privacy, and how its new Orb aims to become a first-principles block explorer designed for internet capital markets.

They discuss Solana’s performance culture, the challenges of indexing petabytes of historical data, and how developers and traders rely on Helius for both high-frequency data streams and consumer-grade UX. Mert also shares his views on meme coins, Solana Foundation, internet culture, Crypto Twitter authenticity, and why teams must aim for exponential growth rather than incremental success.
