An Intro to Crypto
https://www.hunterlabs.org/an-intro-to-crypto/
When you hear the word crypto, the first thing that comes to mind is probably cryptocurrency. However, before Bitcoin, Ethereum, crypto was widely known to be an abbreviation for cryptography, the process of encrypting and decrypting information.
A good introduction to crypto should start with the underlying technology rather than price movements. Understanding distributed ledgers, cryptography, consensus mechanisms, wallets, transactions, smart contracts, and blockchain infrastructure provides a much stronger foundation for exploring the ecosystem. Once these building blocks are clear, it becomes easier to understand how different crypto applications and networks are designed and where their practical use cases come from.
