An overview of ECDSA use in Bitcoin
ECDSA (Elliptic Curve Digital Signature Algorithm) is the cryptographic signature scheme that Bitcoin uses to secure transactions and prove ownership of bitcoins. Here’s how it...
How is SHA-256 used with Bitcoin?
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that plays several critical roles in Bitcoin’s architecture and security model. Core Functions in Bitcoin...
How does Grover’s Algorithm reduce SHA-256 security from 256 bits to 128 bits?
Grover’s algorithm reduces SHA-256’s security from 256 bits to 128 bits through its ability to search unsorted databases quadratically faster than classical algorithms. Here’s how...
