You switched accounts on another tab or window. The Importance of Private Keys In Bitcoin Transactions . If only a single address is ever used, you do not need root seed from which master key (private key and chain code) are generated. but since you can't print a byte array for the user we have to encode it with some encoding technique. As mentioned, WIF is used when you're exporting or importing private keys between wallets. A wallet import format (WIF, also known as a wallet export format) is a way of encoding a private ECDSA key so as to make it easier to copy. Example of Public and Private Keys In cryptography, keys scramble data into a random string of numbers and letters so that attackers cannot access sensitive information. In 2015, in order to show the hugeness of the private key space (or maybe just for fun), someone created a "puzzle" where he chose keys in a certain smaller space and sent increasing amounts to each of those keys like this: 2 0 ≤ random key If that works, I'd assume it's the case that some people have used weak keys (for example, a popular Ethereum wallet would actually generate 256 bits of entropy but accidentally truncate it to 32 bits in an operation), and any funds in those wallets will have been snagged long ago. bitcon/bips). Some examples of popular wallets that use WIF are: Bitcoin Core; Electrum; Sparrow Wallet; BitAddress; From my experience Using two different keys (a public and a private key) is called asymmetric cryptography, which is a vital aspect of a blockchain.
