Fundamentals of Cryptography in Bitcoin: Public/Private Keys, Digital Signatures, and Large Integers

Bitcoin’s security relies on proven cryptographic principles—large‑integer public/private key pairs and digital signatures that authenticate transactions locally without exposing secret keys—making brute‑force attacks infeasible and ensuring that only implementation errors, not the mathematics, can compromise the system.
