Bitcoin Q&A: Cryptographic Primitives
How are cryptographic primitives employed in Bitcoin? What are hashes and digital signatures? How does elliptic curve cryptography work?
See details in Chapters 4 and 6 of 'Mastering Bitcoin': https://github.com/bitcoinbook/bitcoi...

Chapters
0:00 Can you explain the cryptography employed within the Bitcoin network, in digital signatures, in a little more detail, please?
1:33 One-way cryptographic function
2:40 Digital signatures use some tricks of addition and multiplication, knowing that division is impossible, to produce a proof that the person who has created the digital signature possesses the private key, without revealing that private key
4:00 Elliptic Curve Digital Signature Algorithm (ECDSA)
These questions are from the MOOC 9.3 session which took place on March 2nd 2018. Andreas is a teaching fellow with the University of Nicosia. The first course in their Master of Science in Digital Currency degree, DFIN-511: Introduction to Digital Currencies, is offered for free as an open enrollment MOOC course to anyone interested in learning about the fundamental principles.
