Enter TamperLock, an S4S (Script for Script) library (collection of scripts) that aims to stop unauthorised script modification in projects. Every time a script using TamperLock runs, TamperLock verifies the blocks used, and, if the used blocks differ from what it expects, TamperLock stops the project. Here is an example project using a minimal version of TamperLock which contains one block: Say () for () seconds. You will notice that if you add another TamperLock Say () for () seconds block, TL recognises that the script was modified and stops the project. Full version of TamperLock with more blocks coming soon!
