Research: Validity Rollups on Bitcoin

One of the results of the decade-plus research into scaling and expanding the capabilities of blockchains such as bitcoin is the invention of the validity rollup. Given the observed benefits that validity rollups have for the blockchains that have already implemented them, attention now turns to the question of whether they would be beneficial for bitcoin and existing bitcoin L2 protocols such as Lightning, too. We explore this question by examining validity rollups from several angles, including their history, how they work on a technical level, how they could be built on bitcoin, and what the benefits, costs, and risks of building them on bitcoin might be. We conclude that validity rollups have the potential to improve the scalability, privacy, and programmability of bitcoin without sacrificing bitcoin’s core values or functionality as a peer-to-peer electronic cash system.
