What does “crypto” mean?
Crypto is a broad name for digital assets whose ownership or transfer follows cryptographic and network rules. It does not mean that every asset is safe, useful, or valuable.
Read the full lesson ↗Why do people call a blockchain a shared ledger?
Participating computers check an ordered transaction record using shared network rules. A public record does not reveal every real-world fact about the people or assets represented.
Read the full lesson ↗Does every task need a blockchain?
No. A database controlled by an accountable operator can be simpler and easier to maintain. A shared ledger makes sense only when its benefits justify its costs and trade-offs.
Read the full lesson ↗Is owning crypto the same as controlling its keys?
No. An asset may be held by a service for you, or you may control it through self-custody. Custody determines who can authorize a transfer and what recovery might be available.
Read the full lesson ↗Why check a token’s network-specific address?
Names and logos can be copied. Check the intended network and its token mint or contract using an independent trusted source before taking action.
