Schnorr Signatures: A Solution to ECDSA's Malleability in Bitcoin Transactions
Written by Sadiq Ismail In our journey to understand Bitcoin's cryptography, we've already seen how the ECDSA (Elliptic Curve Digital Signature Algorithm) plays a key role in securing transactions. But, as Abubakar Sadiq Ismail pointed out in his previous piece, ECDSA comes with a notable vulnerability;
