Why the world needs a tool like xx messenger

Why the world needs a tool like xx messenger

With xx messenger now live and a growing number of digital freedom seekers flocking in daily (x), we wanted to give everybody, both new users of xx and (inevitable) future converts, a one-stop article outlining the reasons why you need to choose the right messenger. We created xx messenger with the goal of making true privacy and decentralization—and peace of mind— to everyone, and because we see it as a  sheer necessity given what’s been happening to us all in the digital world for many years.

It sure isn’t news that, even with the use of some partially protective software, our personal data, our web searches, our communications, and pretty much everything else we do on the internet is duly recorded, analyzed, and then used to fill the pockets of corporate overlords and their shareholders. But all this data is also being gathered and combed through by intelligence agencies, in what Edward Snowden tells us is referred to as “the full take”–literally all electronic communications around the world on any given day. This pervasive surveillance may seem the lesser of two evils, with the greater one(s) at least in the short term, being such as employer snooping and identity theft, among others. But in the longer term, its destructive potential for society is far worse.

The era of Web3, a still largely imaginary ‘place,’ offers the promise of freeing internet users from today’s continual and omnipresent data abuses and empowering the individual. This promise is based on decentralization. But a “decentralized” web where companies can harvest and sell user data will simply replicate Web2. So it’s imperative that we build the appropriate tools.  For Web3 to be more than a mirage, these tools must ensure that you and I can safely surf this next-generation internet and interact with each other knowing that data about our lives and the things we share belong to us and us only.

That is how communication should be in Web3 and it all starts with xx messenger.

“I have been involved in cryptography for most of my life and have been developing privacy-centric software for a good 40 years. It is my firm belief that privacy plays an absolutely crucial role in the functioning of our society and that every individual, regardless of who they are and where they reside, has an inalienable right thereto. For me, that also extends to the realm of the digital and I haven’t quite found a communications tool that guarantees said privacy. So, I decided to build one.” – David Chaum

Privacy issues, the current personal data status quo—and why it could get a lot worse. 😳

There are literally billions of reasons why what’s been dubbed “surveillance capitalism” is a gargantuan problem for society, here and around the world. Those reasons begin with the continual comprehensive violations of the privacy of everyone on the planet with a smartphone or an internet-linked computer. But the reasons multiply from there, because of what happens to all that stored personal data and what can be done with it. Here are a few of the worst examples. 

1.      Cambridge Analytica

This one made the news around the world in 2018 and even earned its very own Wikipedia page, as well as a Netflix documentary. Cambridge Analytica was the scandal of all data scandals and its impact has reverberated numerous times. t continues to be cited as the major cause of a monumental shift in public sentiment vis-a-vis privacy and its importance.

What happened? Short version: UK-based “psychometric” analytics firm Cambridge Analytica had purchased (and also scraped, contrary to Facebook terms of service) the data of millions of Facebook users. The data was used to design fake social media pages and groups intended to steer undecided voters to support the subsequently elected Donald Trump as President in the 2016 US elections. These manipulative and mendacious ‘nudge’ tactics and the personal data exploit that underlay them were referred to as “psychological warfare”.

2. Facebook’s 533 million users’ personal data breach 

Phone numbers, full names, locations, birthdates and e-mail addresses of 533 million Facebook users from 106 countries were exposed. Not a pretty picture, to put it mildly. If you’re reading this, the chances of your personal data being a part of this breach are actually quite high. Now, imagine what a really powerful computer could do with that data. Stick around and you’ll see what exactly we mean by that.

3. 700 million LinkedIn users’ data leaked and put up for sale

Another platform where ‘secure’ communication really matters. LinkedIn is a place where a lot of business-sensitive information is stored and shared, and a breach of such a magnitude is an enormous disaster, especially considering it accounted for 93% of LinkedIn’s user base.
Scary, no?

4. WhatsApp fined $266 million under EU data protection rules 

Not quite a data breach, but rather an issue of transparency over data processing, following a similar verdict going against Amazon a little while earlier as the European regulator began an enforcement action spree against Big Tech’s mishandling of personal data. Some call it the cost of doing business.

5. 538 million Weibo users’ data breached and available for purchase on the dark web

And no, it’s not just the Western tech giants that suffer data breaches: Chinese media powerhouse Weibo also fell victim to a data exploit. This time around, the data of 538 million users was compromised, eventually making it to the dark web for sale. Albeit the leak didn’t affect as many datasets as the Facebook example above, it still goes to show the gravity of the issues with digital privacy.

Oh, and care to guess the asking price for these 538 million users’ data? $250. 

And those are just some of the headlines that have made their way to the public… Surely there are other instances of similar mishaps that have been either covered up to forestall outrage or are simply still undiscovered.

The Power of Quantum Computing 💣

What is quantum computing?

First things first: You’ve probably heard of quantum computers and the massive and rapid push to develop them to the point at which they become useful for other than highly specialized tasks. Once they reach that point, quantum computers will be able to perform considerably more complex computational tasks than what your device is doing right now—and in fact many tasks even the most powerful existing computers can’t do at all–.

What will make quantum computers exponentially more powerful than their “classical” (non-quantum) counterparts is the way they solve problems. -Classical digital computers convert programs into binary arithmetic, in which every bit of code is built of strings of zeros and ones (bits). For example, each letter of the alphabet is represented as a byte – a string of 8 bits. At every point in a computation, a bit may be either a 1 or a 0. But a quantum computer can hold a bit in what physicists call superposition, in which it is both 1 and 0 at the same time. So the output of a logic gate in a circuit does not have to be either 1 or 0; it can also be (1-and-0). This will allow quantum computers to solve problems orders of magnitude more rapidly than even the fastest classical supercomputers. . 

Modern encryption is mostly based on very large (200-plus digit) numbers that are extremely difficult to factorize and therefore crack. Such encryption is typically used for “uncrackable” passwords and digital signatures, But a computation that would take even a very powerful classical computer hundreds of years could be performed by a quantum computer in minutes. ecrack open code that is currently seen as uncrackable, examples being ‘secure’ passwords and even blockchain networks.

What does that mean for you now and what will it mean for you in the future?

At the moment, viable quantum computing is not yet a reality, at least not publicly. However, it’s a cliche that whatever is sent over or posted to the internet is there forever. So every byte of your data that’s floating around in the cloud is getting primed to be utilized by quantum computers in the not-at-all-distant future. Already, much of the information about you currently on the internet is being read, sorted, and analyzed by artificial-intelligence algorithms. n the majority of cases we know about, that’s being done to optimize ad targeting and increase “engagement” on social media sites, with often socially destructive and sometimes horrifying, as in genocidal, consequences. It is also being accumulated and combed through, as we’ve already noted, by intelligence agencies like the NSA and—it was recently revealed—the CIA (again, in violation of their charter and of legislation passed back in 1975). ., 

But… what happens when the danger materializes and quantum computing finally arrives? Effectively, all that  data is then handed on a silver platter to computers so powerful that they can do anything their operators and the AIs they run want with it. And not just your current data. Every email you’ve ever sent, every social media post you’ve ever made, every search you’ve ever done, every website you’ve ever visited. All of it. Now multiply that by several billion people. The malignant and manipulative uses all that data can be put to once quantum AIs have digested it are almost unimaginable.

In case this needs to be made explicit:  quantum computing is not inherently a bad thing. i. On the contrary, it has  a huge range  of applications  many scientists and technologists have been looking forward to for a long time: everything from rapid 3-D mapping of protein folding or mRNA vaccine and custom cancer-drug design, to smart energy grid management, to hyper-detailed ecosystem or climate modeling. In the hands of a genuinely democratic society, quantum computing could be an enormous force for human and environmental betterment.

The problem here, however, is that technologies even when developed to serve the common  good, is often misused or scaled to an extent where exercising adequate social control over it becomes nearly impossible.

What makes xx the right messenger for Web3? 🎯

Let’s dive into our tech for a minute. After all, it makes sense to know what’s at the back end of the interface you are looking at, and what lets xx messenger check all the necessary boxes.

The xx network’s founder, David Chaum, has dedicated his life’s work to cryptography. He  started off  with “vault” technology, the basis of blockchain, and mixnets, which are used now in protocols like so-called onion routing for email but which also, in radically improved form, are the basis of xx messenger’s metadata protection–as we’ll see. He continued with the invention of electronic money as anonymous as paper cash and its deployment via his company Digicash. All In all, David has spent four decades years building privacy-centered cryptographic solutions aimed at empowering the digital individual and providing a fertile ground for fair and secure internet use.

David – who invented mixnets in the first place before email was even widespread – is also the prime mover behind the invention of cMix, the proprietary technology through which all messages on xx messenger are sent. Cmix, combined with a couple of other techniques, has enabled our messenger dApp to offer  the following features:

  • True privacy
  • End-to-end quantum-resistant encryption
  • Total metadata shredding
  • Scalability
  • Full decentralization

What exactly is cMix and how does it work?

cMix is a type of mixed network or a ‘mixnet’. A mixnet is an anonymous communications protocol aimed at protecting network users’ identity and data. Currently, the majority of internet traffic is encrypted to protect its contents. The issue, however, lies in traffic pattern analysis, which can yield a staggering amount of data leaks. Encryption is therefore not a privacy panacea for  messages you send online! While providing confidentiality and integrity, encryption doesn’t do much when it comes to hiding senders and recipients. .

More specifically, the cMix mixnet protocol David Chaum and our product team have developed in-house protects each xx messenger user’s unique metadata, a term you’ve probably heard or seen before. If you are unfamiliar with it, metadata is essentially the who, what, when, where, and how of a given data point. Or in other words, metadata is the ‘back end’ of your message – who sent it, when it was sent, where it was sent, and via what platform(s)  as well as how often messages pass between sender and receiver. For advertisers and intelligence agencies alike, metadata is actually more valuable than message content, because it cumulatively reveals a user’s entire “social graph,” which is a demographic and intelligence goldmine. Here is a full list of what falls into the category of metadata when it comes to messaging: r:

  • Message sender
  • Message receiver
  • Geographic locations of sender and receiver
  • Message sent time
  • Message received time
  • Message size
  • Sequence of messages
  • Frequency of sent messages
  • Frequency of received messages

You wouldn’t want all of this public, would you?

Using cMix, xx messenger is able to unlink sender and recipient data and protects traffic-analysis attacks. The latter types of attacks are quite prevalent in other privacy-focused protocols, namely onion routing, proxies, and other types of mixnets. So even if you use another mixnet protocol,, and even if your message content is end-to-end encrypted, your data is not 100% safe, nor your identity 100% anonymized.

Surveillance and data privacy are undoubtedly near the top of many  internet users’ concerns list. cMix technology provides full-on protection,, making it impossible to track xx messenger users. Messages and transactions sent over the xx cMix are mixed in batches called ‘anonymity sets’ that are then processed as a group. In each round, just five nodes in the network are selected at random from among hundreds (eventually, as the network grows, thousands) to pass a batch of thousands of messages. Each node reshuffles the messages while simultaneously “forgetting” all information about the previous node, including the previous shuffle. So the mixing instantly “shreds” all metadata and is guaranteed to prevent any third party from analyzing activity patterns and connecting senders to recipients. Even a quantum computer can’t do it.

Another shortcoming of ‘regular’ mixnets is high latency; that is, they are slow and unable to process many transactions at once, rendering them difficult to scale and therefore unfit for widespread commercial use. cMix is a high-performance mixnet that solves this problem too – by incorporating a precomputation process that drastically shortens real-time cryptographic latency (the time it takes to encrypt and decrypt) and lowers computational costs, thereby eliminating the need for expensive real-time public-key operations for senders, recipients, and nodes.
