The Problem With Bitcoin L2s | With Mike Casey
Michael Casey was brought on by MARA to address an often overlooked problem in the world of Bitcoin Layer 2s… they generally don’t contribute much to the security budget of Layer 1 Bitcoin. We often hear concerns about fees being either too high OR too low depending on how you look at it… too high if you’re optimizing for 8 billion people being able to use the network in a self-custodial way—but too low if your goal is maintaining network security as Bitcoin block rewards continue to halve over time. In this episode, we discuss:- Why MARA is funding a Bitcoin side-chain development proje- The power of merge mining in solving this “fee-scaling dilemma” - How Bitcoin was used for payments in a pre-Lightning world- Why L2s ultimately need to pay Bitcoin miners to sustain the network in the long runWe also cover some fun Bitcoin history—like the impacts of Bitcoin’s cultural shift from being “network-focused” to “asset-focused,” why BIP300 may have been a good idea after all, and the little known history of Paul Sztorc’s BitAssets.As always, this episode can be viewed on Spotify or YouTube—full episode in the comments or linktree in my bio.
