Redstone is very slow for building digital circuits, so I thought I could make it much MUCH faster by basically offloading all processing of the circuit to another thread, and also this 'swiftstone' doesn't cause block updates and its rendered separately. so it can go as fast as your PC can handle.
The goal isn't to emulate redstone mechanics one-to-one, This is basically a glorified digital circuit sim with gates that are single-blocks.
If you still need to use redstone in conjunction, don't worry, there will be swiftstone->redstone and redstone->swiftstone converters so signals on these different systems can interact with each other.
