## Description

Louis Bellet explores how state channels can revolutionize high-performance decentralized applications (DApps) in this technical deep dive. Learn how Nitro and Nitrolite enable instant, fee-less off-chain transactions while maintaining blockchain security.

Discover the challenges of designing peer-to-peer state channel networks, the importance of standardization (ERC-7824), and real-world use cases like high-speed trading and multiplayer gaming. This talk is essential for developers building scalable Web3 applications that demand low latency and high throughput beyond traditional L1/L2 limitations.

🇹🇼 *Pragma Taipei*
Pragma Taipei 2025 was held on April 3rd at POPOP in Taipei, Taiwan and was an in-person summit for builders and leaders in the web3 ecosystem. Watch the full Pragma Taipei YouTube Playlist here: 

ETHGlobal's Pragma series takes place in cities around the world, and is designed to be a different kind of event. Pragma is a one-stage conference with founders-only on stage, bringing together a small group of curated attendees and speakers to discuss the future of web3 and reflect on the past.
