one of the main arguments for drivechains, from the author himself, is that it would anchor shitcoins onto the bitcoin network, defending bitcoin from being overtaken by some future superior chain with better features.

this argument is naive at best but feels more like fear mongering than anything else. I think Proof of Work with a fair distribution and no issuer was the real innovation here, and that’s not something you recreate today for a variety of reasons.

Bitcoin doesn’t need shitcoins, shitcoins need Bitcoin.
