Leapfrog filter

Leapfrog filters are a way of making sure that information is correct when it moves from one place to another. They are like gatekeepers that check each piece of data that tries to get through. The filter checks if the data is correct and makes sure it is accurate before it can pass through. The filter uses a system of "layers" or levels to check the data, like a series of gateways that each check a different part of the data before it can go through. In this way, it can catch any mistakes or errors that might be hidden in the data.
