Frequently asked questions.
In today’s digital world, most of us are accustomed to using passwords to safeguard our accounts and valuable data. Private keys are similar to passwords, but much more robust. A Bitcoin private key is a string of random characters known as a 256-bit number. This number is so astronomically big that any attempt to forge or guess it would be a waste of time and resources, even with the world’s most powerful computers.
Bitcoin is a bearer asset. If you have the private key in your possession, the bitcoin is technically yours because you can spend it anytime, just like a gold bar or cash.Your private key is used to spend bitcoin, so it’s the root of your Bitcoin security protection. With a private key, you can generate a public key, which in turn can be used to generate Bitcoin addresses where you send and receive bitcoin. You could think of a private key as a “seed” from which public keys, addresses, and signatures are ultimately generated. In fact, Bitcoiners often use seed phrases, readable sequences of 12 or 24 words, to document their private key.
