Rehash Live Bangkok: Deconstructing Rollups and Layer 2s w/David Silverman (Polygon)

This special live edition of Rehash was recorded during Devcon7 in Bangkok, Thailand.  The episode was initially set to feature a debate between David Silverman (SVP, Strategic Product Initiatives at Polygon) and Kelvin from Optimism on rollups, but a last-minute change led to an in-depth discussion on rollups, interoperability, and scalability in Ethereum with special co-host Jonah Erlich (Co-founder of Den and previously Rehash guest on S8 E1).  David dives into the technical nuances of rollups, including optimistic and ZK rollups, the challenges of decentralization, and Polygon's approach with the AggLayer. He also touches on future developments in Web3, interoperability solutions, and rollup decentralization, accompanied by a spicy twist as David and Jonah sample hot sauces throughout the discussion. 👋 FOLLOW US:  Diana: https://x.com/ddwchen  David: https://x.com/davidesilverman Jonah: https://x.com/Jierlich ⏳ TIMESTAMPS: 00:00 Intro 03:04 What are rollups? 07:08 Optimistic vs ZK rollups 13:20 Interoperability and the future of L2s 19:36 Ethereum's role in L2 migration 21:20 Debating the Optimism solution 24:00 Examples of successful interoperability 27:11 Future of rollups 32:42 Spicy takes 37:15 Follow David and Jonah 🤝 SPONSORS: ​  CrossCats: CrossCats is the only bridge built for altVMs to help you connect to hard-to-reach blockchains so you can access new opportunities and make more money.
