Les Matemàtiques al darrere de les criptomonedes Authors Elitza Maneva Abstract In the context of a presentation on the basics of cryptocurrencies like Bitcoin, we introduce three topics central to modern cryptography: digital signatures, hash functions and zero-knowledge proofs. The mathematical problems that arise here can be used as examples by teachers and professors to encourage the study of modular arithmetic, probability theory, graph theory and computational complexity.
