Cryptography for a World with Quantum Computers

By The Praxxis Team

October 15, 2019

The looming threat of quantum computers means the blockchain community must adopt crypto that can meet the challenge. If quantum computing proves to be as powerful as advertised, most popular blockchains will be vulnerable. Are blockchains doomed? Or can they adapt to this challenge?

When Should We Prepare for Quantum Computers to Break Cryptography?

By The Praxxis Team

October 10, 2019

Now that we have described quantum computing and how quantum computers could break the cryptography underlying many blockchains, we must assess how soon the blockchain community should worry about this threat. Is quantum computing science fiction, or science fact?

How Quantum-Secure is Ethereum?

By The Praxxis Team

October 7, 2019

Ethereum is one of the most popular blockchains in the world today. With the advances being made in quantum computing, and with Praxxis founder David Chaum speaking this week at Ethereum’s Devcon5 conference, the Praxxis team evaluates how secure Ethereum’s cryptography is against a quantum attack.

Why Quantum Computing is a Threat to Blockchain Cryptography

By The Praxxis Team

October 3, 2019

Advances in quantum computing threaten many cryptographic systems and the blockchains that rely on them. To respond to this threat, we must understand how cryptography is used today, and recognize why these systems are vulnerable.

Recognizing Metadata

By David Chaum

August 14, 2019

During a time when the field of cryptography was focused on end-to-end encryption, David was the first to recognize and focus on the issue of metadata. In his latest blog David highlights the moment he discovered the power of metadata, and the potential threat it posed to the future of our privacy.

It Starts With Voting

By David Chaum

August 9, 2019

The publication of David’s 1981 master’s thesis “Untraceable Electronic Mail, Return Addresses, and Digital Pseudonyms” was a breakthrough moment for cryptography and privacy. But the road to that paper started long before, with a discussion about voting in a backyard along the Northern California redwoods.

Privacy Preserving Technology vs. Legislation

By David Chaum

July 30, 2019

The recent hearings on Libra and today’s hearing on cryptocurrency are exciting developments for our booming industry. But we’ve been here before, 25 years ago in fact. Legislation didn’t protect our privacy like some had hoped. It’s time to learn from our mistakes and use new creative technologies to secure our digital future.

Does Elixxir Work?

By Kate Victoria

July 16, 2019

The most common question we get is some variant of “Does Elixxir Work?” As a group with its core in cryptography, we usually assume a baseline of trustlessness in developing solutions. When it came to the progress we’ve made with our tech, it seemed clear that we couldn’t suddenly ask people to trust us.
