When it comes to the “crypto” part of cryptocurrencies, David Chaum’s work predates the crypto ecosystem. His efforts as a renowned cryptographer date back to 1989, long before Bitcoin (BTC) was a thing. 

Chaum developed the protocols that act as the basis of DigiCash — the world’s first digital currency secured by cryptography. As the CEO of privacy-focused network developer Elixxir, David Chaum is working with the Swiss central bank to develop a central bank digital currency (CBDC) that could also attract the crypto ecosystem due to its privacy features.

Named eCash 2.0, the new project aims to develop digital cash that would be “inalienably private” and quantum-resistant to counterfeiting. Since the technical details require a deep understanding of cryptography, Cointelegraph sat down with Chaum at Istanbul Blockchain Week to get a better understanding of the mechanics behind this crypto-friendly CBDC project.
