Here, we look at some examples of how the core concepts of Entangled Rollups can be understood by analogy. Think of two tamper-proof databases or digital spreadsheets (picture Excel-like spreadsheets), which each comprise independent records of economic activity. These spreadsheets are hosted on separate computer networks with incompatible operating systems, making it very difficult to integrate them, and users face significant challenges when they wish to perform transactions that would affect both spreadsheets. Many attempts to bridge these disparate databases involve aggregating transactions into a third-party spreadsheet. This method, however, introduces several significant issues. First, it adds a layer of complexity to the interaction between the databases, as all transactions must pass through this intermediary. This slows down the process, making it more cumbersome for users and prone to errors.
