From a private key in Bitcoin, you can derive the public key. The reverse? That’s where the magic of cryptography begins. It’s a bit like mixing paints—easy to combine a few colors to create a new one, but extremely difficult to later determine exactly how much of each original color was used. In Bitcoin, this works far more mathematically, relying on elliptic curves and a problem that is extremely hard for ordinary computers to reverse. That’s precisely why you can share your public key with the world without revealing your private key. As long as no one finds an effective way to reverse this process. #Bitcoin #Cryptography
