Did you know Satoshi Nakamoto's implementation of public key cryptography in Bitcoin was revolutionary? The elegance lies in its use of elliptic curve mathematics.

In Bitcoin's early commits, Satoshi chose the secp256k1 curve - a decision that perfectly balanced security and efficiency. This curve's unique properties enable the creation of public keys that are mathematically linked to private keys, yet impossible to reverse.

This mathematical foundation became the cornerstone of digital sovereignty in Bitcoin.
