BSV and Digital Signatures

This course introduces how the BSV blockchain (BSV) uses digital signatures, powered by the Elliptic Curve Digital Signature Algorithm (ECDSA) on the secp256k1 curve, to secure its network.

You will explore:

• How digital signatures protect BSV transactions, proving ownership and authorization.
• The role of signed messages, enabling users to prove authorship outside of the blockchain.
• How miner identification works as an optional way for miners to sign and verify their contributions.

By the end of the course, learners will:

• Understand how digital signatures function within the BSV system.
• Recognize the three key contexts where they are applied: transactions, messages, and miner identities.
• Appreciate why digital signatures are essential for authenticity, integrity, and trust in Bitcoin SV.

This course is designed for beginners. No prior knowledge of BSV or cryptography is required — only an interest in learning how trust is established and maintained in the BSV network.
