## ECDSA

ECDSA, or Elliptic Curve Digital Signature Algorithm, is a cryptographic algorithm used to create digital signatures based on elliptic curve cryptography. It is the industry standard for securing transactions on many major blockchains, including Bitcoin and Ethereum.

ECDSA offers high security with relatively small key sizes, making it efficient for resource-constrained environments like hardware wallets and smart contracts. The algorithm relies on the mathematical difficulty of solving the elliptic curve discrete logarithm problem, which is currently computationally infeasible to break.

When a user initiates a transaction, the ECDSA algorithm generates a signature that confirms ownership of the private key without revealing the key itself. This provides a balance of speed, security, and scalability that is essential for global financial systems operating on decentralized ledgers.
