What Is Bitcoin Private Key? Everything You Need To Know !!
Bitcoin uses cryptography to create a key pair that controls access to bitcoin on the blockchain. Each bitcoin key pair consists of a public and private key. A bitcoin private key is simply a large bits secret number that allows bitcoin to be unlocked and sent. Each private key creates a unique signature that authorizes the transaction of bitcoin for the owner.
A bitcoin public key is another large number but allows bitcoin to be locked and received. People can over-complicate explanations by trying to explain digital signatures, signing transactions, and wallet import formats.
These two keys or numbers are related mathematically on the secpk1 elliptic curve. The private key is a randomly generated number plotted on the curve, and the corresponding public key is a related point on that curve.
The real point of this magical curve is that it creates trap door functionality , meaning that once we generate the first point on the curve the private key the corresponding second point public key is easily found but impossible to find in the opposite direction.
Because public kets come in different formats they can start with a 1 , 3 or bc1. There are uncompressed public keys, compressed public keys, and wif format. The private is generated from a part of the software that is specially designed to be able to handle big numbers and generate them at random.
TIP: To get a more hands-on understanding of this you can play around with bitaddress. There a lot, about 10 million million million million million million million million, or possible private keys to be exact. The number of possible keys is so large, that security of bitcoin relies on the assumption that no one will ever randomly generate the same two private keys twice.
In the same way numbers can be expressed as words zero and numerical digits 0 , keys are just a really long string of numbers that have the same properties. Instead of using the word expression of the random number, the seed phrase uses a list of 12 or 24 random words to represent the random number. The purpose of the mnemonic is to convert currency, money, and funds into human-readable words. So that the transfer of value can be written on to paper, or spoken over a cell phone and easily shared.
The most secure way to store private keys safely is offline in cold storage, on a dedicated hardware device with your recovery mnemonic stored separately.
