Cardano Fundamentals
This is the conceptual bedrock for building on Cardano. It explains what a blockchain actually is, the cryptography that secures it, how Cardano reaches agreement through Ouroboros, and how the platform differs from account-based chains like Ethereum. You don't need all of it before you start building, but if you are new to Cardano (or new to blockchains), it pays for itself quickly.

What is a blockchain?
The fundamental architecture of blockchain technology, from distributed ledgers to the trust problem blockchains solve.
Cardano architecture
The four layers that make up Cardano (ledger, consensus, networking, scripting), the reference node that implements them, and the eras the chain has moved through.
Cryptographic primitives
The mathematical building blocks of blockchain security, from hash functions and Merkle trees to digital signatures.
Consensus & Ouroboros
How distributed networks agree on a single truth, from Proof of Work to Cardano's Ouroboros Proof of Stake protocol.
