I wanted to learn crypto. I read a lot of posts. I got overwhelmed. The list of buzzwords was long and unending - proof-of-work, Merkle trees, elliptic curves, smart contracts, DeFi, DAOs, NFTs, ZK-rollups. I switched gears, and started building a prototype based on what I picked up so far.

The basic idea is to take Bitcoin core concepts and design a new cryptocurrency from scratch. We'll build iteratively to help make clear where each component fits into the bigger picture.
