David Chaum Says His New Cryptocurrency Is Quantum Computer Resistant

E-cash inventor David Chaum has unveiled yet another cryptocurrency which he says is resistant to quantum computer attacks. 

In a Blog post issued Aug. 20, Chaum championed the new offering, Praxxis, which has seen a six-month development process. 

The new blockchain follows on from Chaum’s Elixxir project, which debuted in September last year, and is intended to interact closely with its framework. 

The Praxxis consensus protocol simultaneously overcomes the scalability, privacy, and security challenges faced by legacy blockchains, the ‘trilemma’, to deliver the ‘purely peer-to-peer version of electronic cash’ that Satoshi called for in the first few words of his whitepaper. And Praxis currency is also designed to leverage the power of its sister Elixxir’s privacy-protecting platform,” the blog post explains. 

Chaum is widely recognized as one of the fathers of digital money, while his efforts in recent years have become marked as separate from Bitcoin BTC itself.
