Crypto Catalog is a reference site for people who keep running into cryptocurrency terms — blockchain, proof of stake, smart contract, stablecoin — and want plain-English explanations grounded in primary sources rather than marketing copy.
Every page here answers one concrete question, and every technical claim traces back to an authoritative document: the NIST blockchain overview, the original Bitcoin whitepaper, the Ethereum developer documentation, and official U.S. government consumer and tax pages. Where those sources don't answer a question, we say so instead of guessing.
The centerpiece is the Whitepaper Coverage Checklist — a scoring tool that walks you through seven questions any crypto project's documentation should answer, from "what problem does this solve?" to "who controls protocol changes?" It measures how complete a document is, not whether a project is good, and it's designed to be reused every time you sit down with a new whitepaper.
What you will not find here: price predictions, coin recommendations, or investment advice of any kind. This is a catalog of concepts, not a buying guide. Start with What is a blockchain? if you're new, or jump straight to the checklist if you have a document in front of you.
