Financial services (lending, borrowing, trading) offered by centralized platforms like exchanges.
A wallet that stores private keys offline (e.g., hardware wallet). Highly secure for long-term storage.
The process of a transaction being included in a block and validated by the network. More confirmations = greater security.
The mechanism by which a blockchain network agrees on the state of the ledger. Examples: PoW, PoS, DPoS.
A wallet where a third party (like an exchange) holds your private keys. Convenient but less secure.
A decentralized stablecoin pegged to the USD, created by MakerDAO and backed by over-collateralized assets.
