Soft-Fork/Covenant Dependent Layer 2 Review - Report

- "Our goal here is to do an overview of all these proposals, figure out what technical patterns they share, figure out what kinds of new opcodes and other soft fork upgrades they need to function, and create a comparison table of how all the parts fit together."

- "Along the way we’ll also define what an L2 protocol actually is, what kind of scaling Lightning is already capable of, and get an understanding of what improvements we need to do to mempools to achieve all this."
