Elliptic Curve Digital Signature Algorithm (ECDSA)

The Elliptic Curve Digital Signature Algorithm (ECDSA) serves as the cryptographic signature algorithm utilized by esteemed cryptocurrencies like Bitcoin, as well as wallets and exchanges. By employing private keys, public keys, and cryptographic signatures, this algorithm ensures that only individuals possessing the private keys can initiate bitcoin (BTC) transactions. The tBTC system also relies on ECDSA cryptography to tokenize bitcoin.
