It basically generates a hash based upon a timestamp using an incremented seed value, until it's able to create a HASH ending with x number of trailing zeros, at which point it's got a value token. Server side needs to be implemented specifically for each backend, but it should be a no-brainer for most. The point is the algorithm and the idea ...
