Blockchain technology has often faced many limitations when it comes to achieving scalability without sacrificing decentralization. Up to this date, no project has been able to scale to meet today's demands without putting decentralization at risk. I'd be a "miracle" if we get a cryptocurrency that's highly-scalable and highly-secure at the same time.

Now I'm starting to wonder if there's a project that's aiming to achieve "unlimited scalability"? To my knowledge, there isn't a cryptocurrency with an unlimited block size. If there was such cryptocurrency, it would've been highly centralized, making it no different than traditional banks. Still, I'm curious to know if blockchain is capable of scaling infinitely to billions of people worldwide. If it's possible, then governments can use the same technology to replace the monetary system of today.

What are your thoughts?
