It can also be stored offline because it does not need a connection to an actual blockchain. A decentralized ledger is a record of all transactions on a network.
In layman’s terms, if you take a valid address and alter it even slightly, perhaps just changing one of the characters, it will almost certainly become invalid. The chances that your alteration could result in a different valid address are less than 1 in 4,000,000,000 . All mainnet bitcoin addresses begin with a prefix of 1, 3, or bc1. You may notice that some of these addresses are longer and don’t include any capital letters. This is because they are using a different address format called Bech32.

Addresses are used for all typical bitcoin transactions occurring on the blockchain.
Why do cryptocurrencies such as Bitcoin use a two-key system?
Instead, they can be kept in an file, which can be saved anywhere and stored offline. Using two different keys is called asymmetric cryptography, which is a vital aspect of a blockchain.
