BIP 300/301 (Drivechains) Basically programmable and trustless sidechains that uses BTC as a currency. It's such a wonderful concept. It could solve the long-term security budget issue, fight alt coins thus enforcing the 21 million cap, attract even more builders and enable extremely useful feature for you and me. https://www.drivechain.info/

I don't have a very deep understanding of such things, but it was a fun thing to consider for a while.
Just imagining the future and how these incredible technologies will stack and layer creating new potentials Humanity has never had available to it.
