## Description

Join Nader Dabit at Pragma Lisbon 2023 for an in-depth demo of Momoka, the scalability solution powering Lens Protocol’s next-generation Web3 social experience. Learn how Lens leverages Arweave, Bundlr, and Polygon to create a hybrid decentralized storage architecture that dramatically reduces cost and latency while preserving immutability, sovereignty, and user ownership.

Nader explains why traditional blockchains aren't optimized for high-throughput social content and introduces Momoka's gasless, signless UX — delivering Web2-level performance with Web3 guarantees. Watch a live verifier demo, explore Lens’s open-source infrastructure, and see how 64,000+ transactions were processed for just $26.
