A note from the builder

Hi, I’m Cyril.
I built Blocks.

One curious person, building a place for curious people.

I’m Cyril Foday-Kailie, a software engineer based in St. Paul, Minnesota, and the solo developer behind The Book of Blocks. I build AI tools, data pipelines, and web applications.

Why this place exists

Crypto has a lot to say.
Understanding it should feel easier.

I’m building Blocks to bring the scattered pieces together: a clear definition, the history behind a project, the ideas its community believes in, and the market data that puts today in context.

The aim is to make it comfortable to start small and go deeper. Read the quick explanation, follow the evidence, and come back with better questions. There’s room here for both your first “What is a blockchain?” and the details you want to investigate next.

As a solo project, Blocks grows one improvement at a time. My focus is a useful reading experience, clear sources, and tools that help you find your own understanding.
