In this highly technical episode of Rehash, we sit down with Jimmy Chang, Co-founder of Catalyst, to break down some big brain topics in web3 and help listeners better understand blockchain technology. Jimmy dives deep into the definition of a blockchain, as he explains the difference between monolithic blockchains, modular blockchains, and DAGs. He breaks down the 4 pillars of blockchain technology - execution, transaction ordering, settlement, and data availability and he explains how layer2s can manipulate those pillars to achieve a desired goal. We discuss topics like data availability problems and solutions, Rollups and RaaS, and Jimmy shares his vision of a million chain future.We get the inside scoop on what Jimmy is working on at Catalyst, where he got his iconic hat, what he thinks of Ordinals, and some of his favorite experiments. COLLECT THIS EPISODEhttps://www.rehashweb3.xyz/FOLLOW USRehash: https://twitter.com/rehashweb3Diana: https://twitter.com/ddwchenJimmy: https://twitter.com/0xJimCatalyst: https://twitter.com/catalystammSPONSORSLens Protocol: https://lens.xyzAmbire Wallet: https://www.ambire.com/NFT.Storage: https://twitter.com/NFTdotStorageEDITORSEllie: https://twitter.com/elliedotsTyler: https://twitter.com/tylerinternetLINKS Cata Labs: https://catalabs.org/Hitchhiker's guide to Rollups as a Service: https://0xjim.medium.com/hitchhikers-guide-to-rollups-as-a-service-2e3438242adaCelestia: https://celestia.org/⌛ TIMESTAMPS0:00 Intro0:57 Sponsors!5:10 Welcome Jimmy!5:54 What is a DAG?7:48 What is a blockchain?13:43 What is a modular blockchain?16:52 Execution, transaction ordering, settlement, and data availability21:38 Data availability problems23:37 Data availability solutions25:57 A multimillion chain future31:01 Rollups and RaaS34:36 Catalyst 38:32 Jimmy’s experiments40:56 Jimmy’s hat42:50 Apps that would benefit from Catalyst 44:08 Jimmy’s thoughts on Ordinals 46:37 This or That game48:13 Follow Jimmy!DISCLAIMER: The information in this video is the opinion of the speaker(s) only and is for informational purposes only.
