What is Bitcoin?
Bitcoin is a decentralized digital crypto-currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: transaction management and money issuance are carried out collectively by the network.
What is a private key?
A private key in the context of Bitcoin is a secret number that allows bitcoins to be spent. Because the private key is the "ticket" that allows someone to spend bitcoins, it is important that these are kept secure. Private keys can be kept on computer files, but in some cases are also short enough that they can be printed on paper.
What is WIF?
WIF is an abbreviation of Wallet Import Format (also known as Wallet Export Format) and is a way of encoding a private key to make it shorter and easier to copy.
Every single private key can be represented as two different WIF private keys: compressed and uncompressed. A compressed WIF private key starts with "K" or "L" and corresponds to a compressed public key/address. An uncompressed WIF key starts with "5" and corresponds to an uncompressed public key/address.
On our site, we list both, compressed and uncompressed WIF keys/addresses.

What is a brainwallet?
A brainwallet is the concept of storing Bitcoins in one's own mind by memorizing a recovery passphrase. An early old-style brainwallet was created by memorization of a passphrase and converting it to a private key with a hashing or key derivation algorithm (example: SHA-256). This method was found to be very insecure and should not be used because humans are not a good source of entropy.
