Sign without knowing the private key in ECDSA
While knowing one's private key is essential in generating a valid digital signature, using ECDSA makes it possible to sign even without the private key.

Quantum-resistant Bitcoin using Lamport Signatures
Lamport Signatures provide an added layer of security for Bitcoin against attacks triggered by quantum computers, which are increasingly becoming powerful as technology advances.
Bitcoin is not ‘crypto’
There is no crypto in Bitcoin. When people use the word crypto, they are just using the short form for cryptography, which uses tools and codes to create messages intended only for the recipient.
Offline addressing
Author Dr. Craig Wright explained how several possible protocols could be created on top of Bitcoin and described the original protocol and templates that existed in 2009.
BSV Academy introduces new course on digital signatures for Bitcoin developers
The course is divided into four stages, discussing the concept of digital signatures, pre-requisites to understanding ECDSA, technical aspects of ECDSA, and how it forms part of the Bitcoin protocol.
BSV Academy launches free digital signatures course
The three-hour free course is aimed at developers and breaks down digital signatures – both from a theoretical and practical standpoint – with a particular focus on the Elliptic Curve Digital Signature Algorithm (ECDSA) which is utilized in BSV.
ECDSA-based oracles on Bitcoin: An alternative to Rabin signatures-based oracles
sCrypt has developed an algorithm to verify arbitrary data from a certain party in Bitcoin smart contracts; it is based on ECDSA and reuses native keys to generate and verify signatures directly.
