Core lessons
1. What is a wallet?
Wallets store cryptographic keys. They do not "hold coins" — the ledger does. Think of a wallet as a secure signer that proves you control an address.
2. How transactions work
A transaction is a signed message instructing the network to update the ledger. Nodes validate signatures and consensus rules before including it in a block.
3. Decentralization, briefly
Decentralization spreads trust across many participants. Different systems trade decentralization for speed, cost, or governance simplicity.
4. Security basics
Use hardware wallets for large holdings, verify addresses, and beware of social-engineering attacks. Back up seed phrases once and never share them.

When you read news about “layer 2” or “scalability”, the core idea is the same: move frequent, cheap operations off the most expensive shared ledger, while keeping final settlement secure. That allows more use cases without compromising the underlying security model.

FAQ
Q: Is crypto the same as blockchain?
