- Cryptocurrency is a type of decentralized digital currency that investors can buy and sell along the blockchain.
- Some digital assets are secured using a cryptographic key, like cryptocurrency in a blockchain wallet.
- Consortium blockchains, also known as federated blockchains, are permissioned networks that are operated by a select group.

The important part of a wallet — and the part where new users often find themselves getting into trouble — is the private key. Anyone who has access to the private key of a wallet can take control of the balance held there. But unlike a safe deposit box, crypto users who hold their own private keys and make transactions using non-custodial wallets (i.e., a wallet not hosted by an exchange or other third-party) become their own bank.
