xx network FAQ

What are the xx network, Praxxis and Elixxir? 

xx network combines the quantum secure, high performance digital currency and consensus protocol of Praxxis with the privacy-protecting, high speed mix technology of Elixxir.  The result is the first efficient online platform that allows you to quickly and securely communicate and exchange value on your smartphone without revealing your metadata. While many messaging platforms are encrypted, no others hide metadata -- information about your activity -- from organizations that collect and sell data.  xx does.


Praxxis has developed a next-generation, quantum secure blockchain which hosts the xx coin digital currency using a unique consensus protocol. After transactions are mixed through Elixxir, payments are passed to the decentralized xx nodes running the xx consensus protocol to be confirmed and added to the blockchain.  xx network is the only quantum secure, meta data shredding blockchain solution that can combine the speed, scalability, and security properties needed for blockchain technology to achieve mass adoption.

Elixxir technology protects privacy by combining end-to-end encryption with cMix, a revolutionary metadata shredding technology which obscures metadata for messaging and payments and data transfer. With Elixxir, all transactions are mixed together in batches or “anonymity sets” and processed together, thereby shredding all metadata and preventing third parties from analyzing activity patterns and connecting senders to receivers.

Metadata is data about data, like who sent a message or payment, who received it, where it was sent from, and what time it was sent. When metadata is collected and analyzed and exploited by tech companies and governments, it reveals a lot about consumer behavior. xx network fully obscures metadata offering secure, encrypted communications and payments on the first truly private, anonymous, scalable and fast platform.  With xx, you can transact with friends, family, and service providers without the fear of being spied upon.

By combining end-to-end encryption with cMix metadata shredding technology, xx offers unprecedented anonymity between and among parties who use the network.  The xx quantum secure consensus protocol and blockchain protects all information and data from manipulation and tracking.  Finally xx performance can support high volume dApps that require high speed and secure transaction support.

The “flagship” xx messenger dApp allows users to communicate without revealing their contact database or their messaging activity (or content).  At MainNet, high speed xx coin payment functionality will be added.  As the first high performance crypto currency -- easy-to-use, and offering the true cash privacy -- xx coin will be uniquely capable of supporting decentralized, democratic life.

There are several key additional dApps in development that exploit the strengths of xx network (speed to finality, volume, anonymity).  Areas of focus are decentralized fact-checking/content curation, the DeFi market and a better smart contract.

Where is xx network based? 

The xx network team and company (xx labs SEZC) is based and headquartered in George Town, Cayman Islands. xx network uses the Praxxis digital currency and consensus technology developed in Cayman and the Elixxir cMix privacy layer developed in Los Angeles.  

Who developed it? 

xx network integrates technology from two projects and teams: Elixxir and Praxxis, both led by Dr. David Chaum.  Chaum is one of the earliest blockchain researchers and a world-renowned cryptographer and privacy advocate. xx network was founded by Chaum and is led by William Carter, a computer scientist and systems design expert.  The Elixxir technology team is led by Benjamin Wenger. The xx network teams are made up of cryptographers, developers, and marketers all working together to create the most powerful blockchain network for communicating and sharing value anywhere in the world.                                                                                                                            

Who is David Chaum? 

David Chaum is one of the earliest blockchain researchers and a world-renowned cryptographer and privacy advocate.  Chaum first proposed a solution for protecting metadata with mix-cascade networks in 1979. In 1982, his dissertation at the University of California, Berkeley became the first known proposal of a blockchain protocol. Dr. Chaum went on to develop eCash, the first digital currency, and has also made numerous contributions to secure voting technology. Today, Chaum leads the xx network, which combines his decades of research and contributions in the field of cryptography and privacy to deliver state-of-the-art blockchain solutions.

How far along is xx in its progress to MainNet? 

MainNet 1.0 release is planned for February/March 2021 along with the public release of the upgraded xx messenger.  Payment functionality for the xx coin as well as limited trading (trading among non US persons) will be introduced at MainNet 1.0.  In addition to the messenger, early release of other initial xx dApps is planned.

As part of the xx BetaNet implementation the network has grown to over 300 nodes with 60B transactions processed as of mid-February.  The comms layer of the network is being optimized across nodes which are segregated into 8 separate geographic bins (Western Europe, Middle East, Central Europe, Africa, Russia, Asia, Americas and Eastern Europe).

A 4k prime has been introduced to deliver endgame security.  Team size still needs to be increased from 3 nodes to 5 nodes.  Latency for messaging transactions is expected to be ultimately between 2 and 2 ½ seconds.  Speed to finality for payment and value transactions running through cMix is expected to be under 10 seconds.  Throughput for messaging should scale to tens of thousands of messages per second as the network grows while global value transfer transaction volume should be in the thousands of  transactions per second (and could go to 10,000 tps with gigabit network connections).  Current xx BetaNet status is here.

The Praxxis consensus protocol and digital currency, which has been running in Alpha, will be integrated with the Elixxir privacy mix during the Fall 2020 xx Integration TestNet.  TestNet performance was documented on the TestNet dashboard for public review.

MainNet 2.0 will feature decentralized governance with full transfer of value and trading.  MainNet 2.0 is planned for Summer 2021.

As additional historical background, the xx AlphaNet launched in Spring 2020 followed with BetaNet nodes launching in July 2020.  The public selection process for nodes began in Winter 2019 and has continued as part of a monthly, rolling process.  Nodes are now located in almost 50 countries organized into 8 separate geographic bins.

What problems does the xx network address? 

The point of crypto currencies (and blockchain more generally) is to decentralize ownership and power so that coinholders, nodes and users have control as opposed to entrenched, centralized entities.  The blockchain movement, to a large extent, is a populist reaction to a global history rife with exploitation of centralized control by small groups serving their own self interest.

Critical to the blockchain vision, is that network infrastructure be provided by a group of heterogeneous, decentralized computers managed by consensus so that no self-interested party can create unauthorized value by  “printing money”, double spending existing money, stealing money etc.)

In the modern tech world, the introduction of the high speed, global internet has enabled email, social media, and mobile applications transforming the way we communicate and exchange value. But the mainstream companies that have become dominant during this transformation have proven unwilling or unable to protect user privacy, and instead they have opted for maximizing profits based on advertising.

Even with encrypted applications, centralized companies have collected metadata to track and monetize consumer behavior.  Information including sender, recipient, and time stamp for various activities are regularly collected with governments and organizations using this data to manipulate us and ultimately to threaten our freedom.

xx network is implementing blockchain technology and encryption which obscures metadata to offer a truly private, decentralized messaging and payment platform. This means that with xx network technology, there is no way for any third party -- including governments or tech companies or even the network itself -- to see  information about the sender or recipient(s) of communications or payments. Plus, xx network will operate seamlessly so that users can send messages and payments just as quickly as they can with any traditional network.

Why Blockchain? Why is this better than Venmo, Facebook, Paypal, WhatsApp, etc.?

Despite its promise, blockchain remains a mysterious technology to many people. Blockchain is about removing the incentive and ability of self-interested organizations to mismanage platform users and their data. With blockchain, decentralization using incentivized governance mechanisms put users and other stakeholders in control of the development and operation of the platform. 

In xx network, users are paid to make important decisions about the platform and to run the servers and infrastructure themselves. The effect is that you are in control of your data and how it’s used through unbreakable cryptography and social governance rather than demonstrably ineffective regulations, privacy policies, and terms of use. Existing social media and payment platforms have built their businesses on the monetization of your data leading to election manipulation and the selling and leaking of personal data that we see regularly in news headlines. The xx network takes away the incentive and ability for centralized organizations to abuse your data.

How is xx blockchain better than other blockchains? 

Since the early days of Bitcoin, many projects have attempted to develop decentralized platforms capable of providing global-scale payments systems. However, these networks have been burdened by large fees, slow payment confirmation times, high energy consumption, and a lack of built-in security. This has slowed user adoption and prevented decentralized networks from presenting a viable alternative to centralization.

xx network is the first blockchain capable of simultaneously achieve decentralization, speed, privacy, all with quantum-secure technology. Rather than using PoS or PoW, the xx network uses a brand new consensus mechanism called Proof of Quantum Random to achieve maximum performance. In addition, Elixxir integrates metadata shredding to ensure privacy goes beyond encryption.

Does xx’s Proof of Quantum Random use Proof-of-Stake or Proof-of-Work? 

No, neither! The xx blockchain uses a completely new technology deliver unprecedented speed, security, and scalability while maintaining full decentralization on the network. xxBFT allows the xx blockchain to achieve linear authenticator complexity and single block finality. xxBFT is scalable to thousands of nodes and is truly egalitarian, granting every node equal operating time and rewards. Furthermore, xxBFT is quantum secure and requires very low energy consumption, two major advantages over existing blockchains.

How can the xx network, a blockchain, handle large scale communication?

Communication functionality provided by the xx network is not grounded in blockchain technology because successful communication does not require addressing the digital currency “double spend” issue.. Therefore, network wide consensus is not needed in the processing of messages, only in the selection of and management of node teams to ensure the messages will be handled correctly.  As a result, the number of private messages the xx network can handle is not limited by blockchain technology, it is only a function of the number of nodes it has processing messages. As more nodes are added, the network can process more and more messages.

Using the xx network

As a user

As users of online platforms, we generally don’t have the time or energy to research and understand the technology that enables our favorite apps. If we did, we’d be shocked to learn how much personal information these platforms collect and how easily that information can be used to influence our decisions and behavior. The xx network is a new generation of technology that is governed by its users.  The xx network puts you back in control of your information through the use of seamless, easy-to-use apps

These apps may initially be developed by us. The xx messenger will let you communicate and exchange money with your friends, family, and associates while using the most secure cryptography in the world. Ultimately we are working towards making interfaces that would enable your favorite organization and developers and your favorite companies in banking, commerce, and social media to use our technology. In time, we believe you should be able to do most of the things you currently do online but without compromising your identity.

As a developer or company

As the creators and providers of online products, using the right technology and having an eye for future trends is imperative to building competitive and sustainable value. Privacy and security has proven to be the battleground of the future and the xx network will enable you to build valuable applications with the strongest privacy and security properties in the world.

The xxDK is available to enable existing applications to interface with the xx network to send communications with complete identity protection through our revolutionary mix network. Eventually, we will integrate seamless payments and communications.

What is xx messenger?

xx messenger supports messaging that's actually private. Existing privacy messengers encrypt your messages, but they reveal who you are talking to and when you’re talking. Elixxir’s open source cMix technology breaks the link between sender and receiver, fully eliminating your digital footprint. And messages stay end-to-end encrypted.

Your life should be yours. Coming March 2021.

How do I download xx messenger? 

xx messenger alpha testing ended with over 2400 users. The updated xx messenger is coming back in March 2021. To get updates, join the email list here.

Is the xx network free to use? 

 xx messenger is free for users with a verified account. Those .running decentralized applications, smart contracts, and businesses on the xx network can use xx coins to purchase higher bandwidth. 

What is the xx collective?

The xx collective is a global community supporting the xx network. The xx collective app supported alpha testing of the xx messenger and community involvement at events and conferences, but following the transition to BetaNet is no longer available.

xx coin

What is the xx coin? 

The xx coin is a secure, denominated digital currency that can be traded among users and businesses while incentivizing operations on the xx network. The xx coin is used to incentivize governance that enforces transparent operation of the network and empowers users to participate in the ecosystem. The xx coin is also used to pay for high volume messaging, effect payments and for dApp incentivization.  Because the xx coin is secured by the xx network, it is completely private and quantum secure.

How can I purchase the xx coin? 

Prior to MainNet, the xx coin has been available to non-U.S. persons in limited public sales. To learn more, please visit https://xx-coin.io/

How many xx coins will there be and how will the xx coin be distributed?

In the xx genesis block, one billion xx coins will be minted. Initial distribution of xx coins will be via an ERC-1404 smart contract which will be converted to native xx currency at MainNet. Denominated xx coins emulate physical money with pre-set values, in base-two, that is, 1, 2, 4, 8, 16, 32, etc., and can only be spent once because of the type of signature used. This is the most private way to send money on the network. The xx network also will support wallets so that users can send and receive payments repeatedly without creating a new public address and multisig wallets for transactions that require at least two parties to sign off will also be supported.

How will xx coins be allocated and distributed? 

70 percent of xx coins are intended to be disbursed or allocated to the xx network community through public sales, private sales, and community incentivization programs. 25 percent of xx coins will be reserved for WBM Corp., developers of the Praxxis software, and project creators. 5 percent of xx coins will be reserved for the xx network ecosystem, including developer rewards. The xx network considers usability, privacy, and security to be its top features.

How does the xx network generate revenue? 

xx nodes receive block rewards, which are composed of a share of the income the network generates and an inflationary reward of newly minted xx coins. Inflation is expected to be roughly .5 percent to .8 percent. As MainNet goes live, during the first several years, inflation may temporarily be higher. A small portion of block rewards go towards governance to incentivize participation, and to a foundation to cover developmental costs. 

xx nodes

What are xx nodes and how do they work on the xx network? 

xx nodes are servers that collectively operate the xx network. xx nodes must be reliable and high-performing to achieve the necessary capability and scalability to serve a global user base and replace centralized systems. The xx network promotes an egalitarian approach, where any independent individual or organization is welcome to apply to the xx network to become a node. 

How are nodes selected?

To learn more about node selection, check out the nodes page. MainNet nodes, which will number in the thousands, will be selected through a governance process.

Decentralized Governance

How does governance work on the xx network? 

The xx network is completely decentralized, meaning there is no central authority managing the xx network and resolving disputes. The xx network requires governance to achieve collective agreement on code, core data updates or even adding or removing nodes (to name a few critical network issues). Governance within the xx network relies on sample voting, a process developed by Dr. David Chaum which randomly polls a subset of the voting population and incentivizes the subset to make informed decisions. 

What is sample voting?

With sample voting, a subset of voters can investigate and cast a vote on a given topic. As a result, selected voters can be incentivized with fixed or lottery-based rewards without any linking of compensation to votes. This governance process ensures fairness and transparency within the xx network, and technical measures are in place to prevent bad actors from infiltrating the governance process and sample voting system.
