## Description

At Pragma Paris 2023, Martin Derka and Jan Gorzny from Quantstamp unveil new Ethereum Foundation-funded initiatives focused on Layer 2 security and transparency. Martin introduces a proposed open standard for Layer 2 block explorer APIs, aiming to unify data access across diverse L2s like Optimism, Arbitrum, zkSync, and Scroll. By defining modular, extensible APIs and publishing them as open source on GitHub, the Quantstamp team invites developers to build better explorers and support broader interoperability across rollups.

Jan follows with a deep dive into Quantstamp’s second grant initiative: a comprehensive security evaluation framework designed to fill gaps in current analysis tools like L2Beat. This framework covers over 130 detailed questions addressing escape hatches, trust assumptions, fraud proofs, hardware dependencies, and other critical security aspects of L2s. The talk outlines how to score rollups based on feasibility and resilience, and calls for community contributions to improve and validate the models. If you're building or auditing rollups—or just care about secure scaling—this is a must-watch.

🇫🇷 *Pragma Paris*
Pragma Paris took place at the Pavillion Vendome in Paris on July 20, 2023, and was an in-person summit for builders and leaders in the web3 ecosystem. Watch the full Pragma Paris 2023 playlist here: https://youtube.com/playlist?list=PLXzKMXK2aHh42f0yI-hyeOCbNZpvV2fIT&si=Ez6ych6OAdn_sq1D

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. Ever since we first introduced our new event series Pragma in Tokyo of the spring of 2023, we have been fostering a curated, global community of individuals who deeply care about web3.
