2. What is Blockchain Wallet and How Does It Work?

A blockchain wallet is a piece of digital software that stores private and public keys, as well as tracks and records all transactions involving those keys on the blockchain. A blockchain wallet, in theory, does not store cryptocurrency; instead, all records belonging to these keys are stored on the blockchain on which the wallet is hosted. Blockchain wallets have public and private keys. A public key and a private key are used in a similar way in blockchain wallets. A public key is similar to an email address in that it can be shared with others. When your wallet is created, a public key is created as well, which you can share with others to obtain funds. The private key is a closely guarded secret. It’s similar to your password in that it shouldn’t be compromised, and you shouldn’t share it.
