Bitcoin Security Relies on Elliptic Curve Cryptography The security of Bitcoin depends on a cryptographic method known as Elliptic Curve Cryptography. Each Bitcoin wallet uses a private key a secret 256-bit number to generate a public key using a mathematical curve called secp256k1. This system functions as a one-way mathematical process. While generating a public … Continue reading Quantum Computing Threat to Bitcoin: How a Future Attack Could Steal Funds in Minutes
