David Chaum’s Elixxir Delivers First Platform Capable of Protecting Privacy by Obscuring Metadata



Reading Time: 2 minutes


Elixxir, led by David Chaum, the “father of online privacy,” announces Elixxir’s unprecedented privacy-protecting blockchain technology will be launched on a BetaNet supported by node operators on six continents.

The Elixxir platform will allow users to communicate without revealing metadata related to their activities—that is, Elixxir will obscure who sends messages, when messages are sent, where they are sent from and who receives them.

Metadata recently became a hot topic when Facebook CEO Mark Zuckerberg laid out a Facebook “privacy-first vision for social networking,” focused on readily available end-to-end encryption with no attention to protecting metadata. In an open letter to Zuckerberg covered by Forbes, Chaum described the Zuckerberg approach to privacy as “fooling those mostly young people [Zuckerberg] says are moving off newsfeed to messaging into believing that end-to-end encryption means privacy.”

Though end-to-end encryption obscures message contents, it does not protect the behavioral details of people’s activities. Elixxir nodes, which operate a highly efficient decentralized mix network, provide full metadata protection for users as well as end-to-end encryption. The Elixxir mix network technology, invented by CEO David Chaum, delivers unprecedented speed by using precomputation to create a mix network framework in advance. After precomputation is complete, each team of nodes stands ready to rapidly process a batch of messages, quickly breaking the links between message sender and recipient, as well as links between users and their blockchain message history.

Elixxir BetaNet Nodes

In January, Elixxir initiated its BetaNet node selection process with a community survey addressing preferences for platform governance, incentives, and community structure. Based on survey results, a node application was designed to determine which nodes would operate the Elixxir BetaNet. Since the release of the application, Elixxir has received hundreds of applications from around the world. Elixxir plans to launch a privacy-protecting, decentralized BetaNet supported by node operators on six continents.

Members of the public interested in furthering Elixxir’s mission of protecting the privacy and security of users are encouraged to apply to run a BetaNet node before Friday, April 19th on the Elixxir website.

Bounty Program

As part of its efforts to rally the privacy community, Elixxir has launched a bounty program to raise the profile of the BetaNet node selection process. Participants who refer applicants who successfully run a BetaNet node will be eligible for up to two extra nodes in Elixxir’s MainNet.

CCELL Launches Environmentally Conscious Eco Star AIO Vaporizer




SHENZHEN, China, April 15, 2024 /PRNewswire/ — CCELL®, the world’s leading technology brand focused on creating trendsetting vape hardware products and advanced vaporization technology, today announced the launch of the Eco Star, the company’s all-in-one vaporizer focused on sustainability, wide-ranging oil compatibility, and ease of use.

The Eco Star’s casing material is made of biodegradable and plant-based PLA, a material that can be decomposed by bacteria or other living organisms. By adopting this type of eco-friendly casing, CCELL seeks to provide an option that can reduce the cannabis industry’s overall environmental impact and build a more sustainable society.

Built within the casing is a removable and recyclable lithium-ion battery. This thoughtful pull-apart design allows consumers to easily remove the battery before disposing of the casing, empowering them to contribute towards a greener Earth.

The Eco Star also features complete compatibility with all types of cannabis oils, clog-free dual air vents, and an isolated airway that ensures the cleanest possible vapor.

With increasing environmental challenges worldwide and tightening regulations on vape products, the Eco Star was introduced with the intention of raising environmental awareness across the industry.

The company has also implemented other measures to align its practices with its long-standing sustainability-focused values. These include offering biodegradable and plant-based PLA mouthpieces among its customization options. Additionally, the company uses energy-efficient aqueous processing in producing its patented ceramic heating cores to reduce greenhouse gas emissions.

Before the product’s official launch, CCELL provided their customers and consumers with an early look at the Eco Star at TPE24 and Hall of Flowers Ventura in the US, and Spannabis Barcelona in Spain.
