The necessary scalability of Layer-1 on blockchain

Blockchain has opened up many possible applications, including payments, tokenization, smart contracts, and in general, data access management. For beginners, a recent article The Crypto Story written by Matt Levine on Bloomberg is a good read. It explains quite well in non-technical language some of the problems blockchain could potentially solve, as well as the problems it currently has. Especially, the article makes a good common sense case for the need for a new kind of database to replace the existing ones, something that the current crypto world largely misses.
