Rollups have become the narrative focus of scaling Bitcoin lately, becoming the first thing to truly “steal the limelight” from the Lightning Network in terms of wider mindshare. Rollups aim to be an off-chain layer two that is not bound or constrained by the liquidity limitations that are central to the Lightning Network, i.e. end users required someone allocate (or “lend”) them funds ahead of time in order to be able to receive money, or intermediary routing nodes requiring channel balances that can facilitate the movement of the payment amount all the way from sender to receiver.
These systems were originally developed to function on Ethereum and other Turing complete systems, but as of late the focus has shifted to porting them to UTXO based blockchains such as Bitcoin. This article is not going to discuss the current state of things being implemented on Bitcoin currently, but going to discuss the function of an idealized rollup that people are aiming for in the long term
