S4 E9 | Millions of Modular Blockchains w/Jimmy Chang

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.
