The grue lurks in the darkest places of the earth. Its favorite diet is adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen by the light of day, and few have survived its fearsome jaws to tell the tale.

Dusk Foundation Launches the First Communication Network; The Dusk Network, a decentralized communication infrastructure that enables the secure transmission of data between peers using the platform’s privacy-based cryptocurrency. The Chairman, Emanuele Francioni will be discussing the Dusk project with us in this interview.



1 ) Please tell us your name and about yourself?
My name is Emanuele Francioni, and I am an engineer with 20 years of experience in software development as a manager and lead architect. I have delivered multi-million dollar technology projects for top corporate organizations, such as TomTom, Commerzbank and Vitrociset. I am also a successful entrepreneur with a proven capital raising track-record and several patents published in the realm of distributed sensor networks, connected vehicles and blockchain technology. Currently, I lead an international, multidisciplinary team within the Dusk Foundation with a view to research and develop the Dusk Network.

2 ) What is Dusk Network?
The Dusk Network is a decentralized infrastructure focused on providing the sweet-spot between privacy and transparency in payment, communication and asset ownership transfers.

We believe that granting the appropriate confidentiality can encourage the adoption of decentralized systems over centralized ones. Taking the financial market as an example, leakage of market positions and trade history offers unfair advantages to competitors. That’s why trading firms are going to operate on decentralized markets if and only if their privacy is protected. At the same time, regulators will reject platforms with unsatisfactory auditing and KYC procedures. Dusk Network was conceived to solve this and other use case scenarios where privacy is an important enabler for the advancement of a truly decentralized economy. Other notable examples are the issuance of confidential security tokens, compliant with regulatory frameworks or the provision of channels for secure audiovisual conferencing and file transfer. Dusk Network uses its own digital currency, DUSK, for incentivizing permission-less participation to the network and transfer value securely among peers.

3 ) Tell us more about anonymous data sharing among peers and why Dusk is focused on this area of communication.
When the internet was originally created, many important components, like a customizable privacy layer, were intentionally kept out of the foundational protocols to avoid over-complicating the initial infrastructure. Throughout the years, third parties saw the business opportunity to offer such functionalities for a premium, contributing to the creation of the lucrative cybersecurity market. These companies understood very well that privacy is an absolute prerequisite for widespread adoption of any technological innovation both in the public and private sectors.

In this era of easily accessible mutually distributed ledgers, confidentiality is even more important. The lack of privacy in many blockchains practically translates to broadcasting transactions on open ledgers that may very well be the settlement of medical or legal bills, auction bids, wages or indeed, trade secrecy around supplier sources and pay rates.

With Dusk, we aim to enable privacy-oriented communications and data transfer in a safe and decentralized environment where content providers and network enablers are compensated for their contribution.

4 ) What is the current problem facing the confidentiality and compliance requirements for launching Securitized Token Offerings?
Current solutions are based on protocols and frameworks which were not intended to handle the strict KYC and privacy requirements connected to security trading.

With Dusk, we will develop a new token standard, with configurable privacy, which we intend to use to allow the issuance of confidential security tokens. The idea is to separate the confidentiality of the currency transactions (thus preserving the fungibility of DUSK) from that of asset ownership transfers, where the purchaser of an asset/security needs to satisfy KYC requirements at protocol level to complete an ownership transfer. The KYC procedure/provider is left to the token issuer and the asset purchaser has the capability of disclosing the transfer details to the authorities upon request.

5 ) What are the major features and services provided by Dusk Network?
The Dusk Network solves the problem of private and secure data transfer, low-latency transmissions and paying for time-unbound communications with cryptocurrencies. This enables the anonymization and decentralization of media-on-demand services, audiovisual conferencing, confidential file transfer, compliance of security tokens, and much more.

6 ) Do you have any current opportunities for investors?
There is an ongoing private placement and we are highly selective in picking the right partners to help us on our journey. Potential investors can e-mail pledge@dusk.network and include their desired investment amount and a brief pitch explaining their perceived value add.

7 ) Would you like to share your Token Economy with us, why is your cryptocurrency relevant for this project?
Power and financial gain are inversely correlated in the Dusk Network, which uses a novel consensus mechanism called SBA*. The system roughly knows two types of players; provisioners and nodes. Provisioners earn a steady ROI, and nodes compete for block rewards.

SBA* uses existing ideas such as Cryptographic Sortition, combined with concepts like stealth time-locked transactions in order to implement simple but secure communication that can be audited.

By splitting tasks based on intensity and relaying them to transaction and non-transactional nodes the network’s speed greatly increases, whilst decreasing the chance of a partitioned network, and guaranteeing a higher availability of the entire network. Using SBA* there is zero chance of an unintended fork of the blockchain, meaning there will be no doubt about what the main branch is. This translates into the appealing property of achieving transaction “finality” as soon as consensus is reached for a new block.

In addition to finalizing a new block onto the chain, Notaries are also responsible for a secondary procedure which generates the block rewards through a set of coin-base transactions, essentially minting new DUSK. This new DUSK will be sent to the address of the Block Generator – the successful lottery candidate. Provisioners do not gain their reward by winning sortition, rather they gain a fixed ROI at the end of a block. This ROI is also a coin-base transaction and is awarded to all provisioners, not just those who took part in this specific block committee.

Counterintuitively, the rewards paid are inversely proportional to the staked amount, where bigger stakes get proportionally less rewarded, with respect to smaller stakes.

This measure is novel and to our knowledge, not a viable option outside of the Dusk Blockchain. The motivation is twofold. Together with preventing the ‘’rich get richer’’ scheme, the intention here is to create a counter position between power acquisition, intended as the capability to influence block generation by being selected as part of the Block Committee, and currency, intended as the financial benefit acquired from running Provisioners.

Considering that SBA* is already protected from Sybil attack by making it probabilistically disadvantageous to dilute a stack into several balances, similarly, by reversing the proportion between rewards and stake, the system prevents financially motivated participants benefiting from organizing themselves into a few Provisioner pools at the expense of decentralization.

The block rewards, together with the provisioner’s ROI, will form the DUSK network’s inflation rate. You can read more on the DUSK network’s economy in upcoming articles focused specifically on how the whole network will operate economically, however, I can say that incentives will align with decentralization and early adoption.

8 ) The cryptocurrency market still remains volatile and currently experiencing downward trends, what will be the benefits for your crypto holders?
Research indicates that cryptocurrency returns are largely unaffected by the current market trend.

(https://lunardigitalassets.com/blockchain-research/2018/analysis-ico-performances-bull-vs-bear/)

Ultimately, the benefits of picking high-quality projects with a strong team and long-term vision speak for themselves.

9 ) Could you tell us about your team and customer support?
We have a growing team of nearly 20 developers and engineers working on Dusk, and a small, highly efficient team of between 4 and 5 people (at any one time) who are focused on the business and fundraising side of things.

As our proposition is largely that of an ecosystem and a strong tech arm is key. However, a strong business arm is also important. Together with a solid legal partner, and have a team of very good advisors who will soon be announced.

Customer support around the project will happen through any of our social media channels, most notably e-mail and Telegram. We’re employing the best 24/7 community management team to make the Dusk Network community a success

10 ) How Safe is Dusk Network, would you like to talk about your legal and security measures?
The Dusk Network is exclusively using established, appraised protocols and frameworks in order to achieve maximum security and scalability for the platform.
Everything we produce is, or will soon be, public and can be freely examined and vetted by the open source community.
Moreover, we have partnered with two major international research centers in order to provide open feedback to the cryptography embedded within the platform.

ABSTRACT
In order to satisfy a broad set of data transfer scenario, the Dusk network adds an additional layer of security to the IP protocol suite (used mostly in a peer-to-peer fashion). Through the adoption of a mix of established strategies and novel techniques, the Dusk network has been conceived specifically to protect the privacy of the communicating peers from any form of eavesdropping while satisfying a variety of challenging use cases varying from fast communication (e.g. voice calls) to large data transfer (e.g. file transmission). Dusk circumvents the notorious unreliability of crowd-sourced infrastructures by embedding economic incentives into the core mechanism of the network itself. Such incentives are designed to encourage peers to partake in the network in a permission-less, anonymous and private fashion

Dusk in a Nutshell
The Dusk Network is a decentralized infrastructure focused on providing the sweet-spot between privacy and transparency in payments, communication and asset ownership transfers. It departs from consensus mechanisms like PoW/PoS, which are poorly suited for privacy, to introduce a new privacy-oriented consensus mechanism called Segregated Byzantine Agreement. Dusk is a new blockchain that provides true privacy and a fast and a secure streaming mechanism called Secure Tunnel Switching (STS), all powered by a privacy-oriented cryptocurrency: DUSK.

This means that we are building the first blockchain enabled platform that allows for streaming, file transfer and storage, and video/audio conferencing, all paid in crypto and fully decentralized, unsurveilled, and uncensorable. Our roadmap focuses on three main use cases; payments, digital asset transfer, and p2p communication. Especially in the asset transfer area Dusk aims to be the first platform to reconcile the requirements set out by both businesses and individuals with regulatory auditability requirements. This means that our confidentiality and privacy ecosystem will become the perfect, compliant, launching pad for Security Token Offerings (STO’s).

Besides technical innovations Dusk Network is a project that will deliver according to a strict project schedule, combining decades of IT delivery experience. The Dusk Network’s research and development is coordinated through the Dusk Foundation, a non-profit foundation that focuses exclusively on delivering the Dusk Network, and the academic, humanitarian, and commercial benefits it brings. Read our whitepaper Here.

The Dusk Network consists of three layers:

1 — DUSK Anonymous Network Layer

A gossip oriented communication tier inspired by I2P.

2 — Segregated Byzantine Agreement

A novel privacy-oriented consensus algorithm vastly more efficient than PoW or PoS. Powered by Proof of Blind Bid.

3 — Secure Tunnel Switching

A protocol allowing cryptocurrency payments for time-unbound and fast data transmission.



(Dusk Network’s three layers.)

We conceived the Dusk Network to be the first unrestricted and fully distributed communication network that does not compromise high data-rate transmission capabilities with the security and anonymity of its peers.

The system features a new consensus algorithm vastly more efficient than proof-of-work or proof-of-stake called Segregated Byzantine Agreement, and built on top of a low-latency gossip network which utilizes non-repliable datagram and garlic routing in order to prevent IP Address propagation.

Finally, the Dusk Network is complemented with an off-online file transfer mechanism and with realtime Dusk payment channel to enable undetectable and fast peer-to-peer data communication through a technique we call Secure Tunnel Switching.

Why Dusk?
The very existence of freedom of expression, access to cultural heritage, information pluralism and economic liberty depends on the availability of a mean of communication capable of guaranteeing uncontrolled exchange of information and messages.

The Dusk Network was conceived for this purpose: to provide its peers with an unsurveilled and unstoppable network infrastructure that grants them the possibility to communicate freely while safeguarding their identities.

Everything within Dusk Network is skewed toward decentralization, privacy and communication efficiency: from the anonymous transport layer which solves IP tracking to the Secure Tunnel Switching protocol which allows efficient data transmission paid for through a blockchain-based digital cash called DUSK.



Use Cases
The Dusk Network solves the problem of secure data transfer, low-latency transmissions and paying for time-unbound communications with cryptocurrencies. This enables a sweet spot between transparency and privacy, and enables the decentralization of:

  • Payments
  • Digital Asset Transfer (STO’s)
  • P2P Communication (Confidential Streaming)
This means that the Dusk Platform can function as an infrastructure for a decentralized service like Netflix, WhatsApp, YouTube, or a communication protocol for a drone fleet, a service where whistleblowers can safely communicate, a platform where cultural or political censorship is impossible, or the place where a business seeks to tokenize its equity without having to go through an arduous IPO process where the costs outweigh the benefits.

Conclusion
The Dusk Foundation is leading the R&D and delivery of the Dusk Network, a new blockchain that uses several technical advancements to deliver an ecosystem laser focused on providing the best trade off between privacy and transparency per use case.

The Anonymous Network Layer explained
What is the Dusk Network?
The Dusk Network is a decentralized infrastructure focused on providing the sweet-spot between privacy and transparency in payments, communication and asset ownership transfers. It departs from consensus mechanisms like PoW/PoS, which are poorly suited for privacy, to introduce a new privacy-oriented consensus mechanism called Segregated Byzantine Agreement. Dusk is a new blockchain that provides true privacy and a fast and a secure streaming mechanism called Secure Tunnel Switching (STS), all powered by a privacy-oriented cryptocurrency: DUSK.

In this introductory series we aim to take a look at specific aspects of the Dusk Network and explain them in a nutshell. In this article we will look at Dusk’s Anonymous Network Layer, a gossip oriented communication tier inspired by I2P. The Dusk ANL serves to enable full privacy for its decentralized network, and we will explain some of its components in this article.

For a detailed description of The Dusk ANL please refer to the whitepaper.

What is the Dusk Anonymous Network Layer for?
In the vast majority of blockchain implementations, network communication protocols limit themselves to just embracing the privacy standards we have in place today for our daily internet needs: TCP/IP, UDP, SSL for encrypting communication channels to name a few. These protocols are necessary to interconnect network devices on the internet, or as a communications protocol in a private network.

While this can be considered acceptable for centralized environments or platforms where user privacy is not the main proposition, the privacy requirements established with the Dusk network impose the adoption of technology offering a much higher level of privacy protection. To achieve this goal, Dusk is enabling full anonymity over its decentralized network by integrating an advanced, custom bi-directional routing, fully compatible with I2P’s Garlic-Routing technology for all its networking communications, but extending the underlying protocol not only for the deployment of additional functionality (such as fully anonymous file transfer) but also for allowing the default anonymous gossip protocol which powers the entire Dusk network.

The proposed architecture has been designed to make it computationally infeasible for an eavesdropper to tell apart Dusk related traffic from other network activities. Additionally, it should be very hard for any network node to associate a transaction with the IP address of the original initiator.

How does it work?
Dusk’s ANL is inspired by and compatible with I2P’s Garlic Routing technology. Garlic routing generally refers to two things; Layered encryption, and the bundling of messages together. Garlic routing was in turn inspired by ‘Onion Routing’ (TOR). It is relevant to briefly start at the beginning to explain the decision made for the Dusk Network. Onion Routing is a technique that builds paths (tunnels) through a series of peers. Messages are encrypted a number of times, sent through the tunnel, and each peer in the tunnel strips away a layer of encryption and finds just the information it needs to send it onwards. The message and its routing instructions are only fully exposed at the end of the tunnel, once all the (onion) layers have been peeled back. Garlic routing is conceptually similar, but bundles messages together, which makes it more efficient, and makes it more difficult to track a single message if you are insistent on exposing a communication’s intended endpoint.

The Dusk Network uses a more advanced version which roughly works as follows:
  • 1. Alice and Bob want to transact/communicate.
  • 2. Alice and Bob are a node or connect to a node.
  • 3. The node connects to a Voucher Seeder, and obtains a signed list of active nodes.
  • 4. The node chooses a node from the list to act as an entry tunnel to the Dusk Network, thus bootstrapping Alice’s connection.


  • 1. Alice’s Entry Tunnel forwards non-repliable packets to the Dusk Address of other nodes.
  • 2. These nodes gossip the data further to other nodes until the message is propagated far enough through the network to reach Bob’s Exit Tunnel.
  • 3. Bob receives the transaction/communication.


The Dusk Approach
Compared to similar solutions, the Dusk approach offers the following benefits:
  • 1. Makes use of packet routing, instead of circuit routing. This means transparent load balancing of all networking message across peers, instead of a single tunnel.
  • 2. Multiple packets are joined together in inconspicuous messages, making it exponentially difficult for an attacker to expose network communications.
  • 3. True decentralization: it uses a distributed directory to have an overview of the network, as opposed to relying on a centralized bulletin board.
  • 4. Uni-directional tunnels guarantee that incoming and outgoing traffic is kept decoupled; a measure engineered to enhance transmission unlinkability through data stream separation.


Conclusion
The ANL’s chief concern is to hide the identities of our transactors, most notably their IP Addresses. Many current privacy blockchains don’t have an IP obfuscation feature, and the implementation of Garlic Routing together with a gossip protocol ensures that a sender’s IP address will never be reconstructed.

SBA* in a Nutshell

What is the Dusk Network?

The Dusk Network is a decentralized infrastructure focused on providing the sweet-spot between privacy and transparency in payments, communication and asset ownership transfers. It departs from consensus mechanisms like PoW/PoS, which are poorly suited for privacy, to introduce a new privacy-oriented consensus mechanism called Segregated Byzantine Agreement. Dusk is a new blockchain that provides true privacy and a fast and a secure streaming mechanism called Secure Tunnel Switching (STS), all powered by a privacy-oriented cryptocurrency: DUSK.

In this introductory series we aim to take a look at specific aspects of the Dusk Network and explain them in a nutshell. In this article we will look at Dusk’s consensus mechanism, called Segregated Byzantine Agreement, or SBA*. SBA* is a new consensus algorithm vastly more efficient than proof-of-work or proof-of-stake, and it was engineered to provide the best possible trade-off between security, efficiency and flexibility.

For a detailed description of SBA* please refer to the whitepaper.

The mechanics behind SBA*
SBA* uses existing ideas like Cryptographic Sortition(lottery), and combines it with concepts like stealth time-locked transactions to implement simple but secure communication that can be audited. SBA* makes use of a few different types of actors in the network to reach consensus:
  • 1. (super)Nodes. These are points in the network that facilitate transactions. They compete with each other for the generating and proposing blocks. These are computationally very light tasks, and a node will not require high computational power, or a big stake.
  • 2. Provisioners. These are nodes that have committed a certain minimum stake to the Dusk Network and take care of more intensive tasks such as block verification, voting, and notarization (VVN operations). These types of nodes are non-transactional.

By splitting tasks based on intensity and relaying them to transaction and non-transactional nodes the network’s speed greatly increases, whilst decreasing the chance of a partitioned network, and guaranteeing a higher availability of the network. Using SBA* there is no chance of an unintended fork of the blockchain, meaning there will be no doubt about what the main branch is. This translates into the appealing property of achieving transaction “finality” as soon as consensus is reached for a block.

Phases of the consensus mechanism
SBA* foresees different subsequent cyclic phases:
  • 1. Block Generation Sortition — nodes participate in sortition(lottery) to acquire the right to broadcast a block proposal.
  • 2. Default Block Generation Sortition — run by Provisioners in parallel to the Block Generation Sortition. They will propose a default empty block, in case consensus is not reached on the proposed block.
  • 3. Validation — run by a subset of Provisioners called Verifiers. Verifiers confirm the legitimacy of the block proposal and its proposing candidate. If everything was done correctly they will sign the proposed block, otherwise they will sign the default block proposed by the provisioners.
  • 4. Voting — a number of rounds each of which run by a different subset of Provisioners called Voters. Once consensus is reached on the block it can be notarised and added to the chain. If consensus is not reached they will vote to add an empty block.
  • 5. Notarisation — the Voters which reached voting consensus on the pre-block are called Notaries. Their public key is added to the pre-block and they play the role of Verifiers in the next block’s Validation phase. The pre-block is then turned into an official block by the Notaries.


Sortition
VVN Operations are conceptually easy to grasp, and relatively self-explanatory. They merely explain how a proposed block is tested and potentially added to the blockchain. The sortition mechanism that plays a big part in the first stages of SBA* however is worth spending a bit more time on.

A node that wishes to participate in the sortition (and become a Block Generation candidate)is first required to lock an arbitrary amount of DUSK. A time-locked transaction is a special transaction where the output is un-spendable for a predetermined period of time. In order to participate to the Sortition lottery for proposing a block, the candidate performs a time-locked transaction toward a Stealth Address. Such a transaction is indistinguishable from the normal others. After completing this transaction the candidate receives a lottery outcome, think along the lines of a lotto number, and gossips this to the rest of the network.

After all participating nodes (candidates) have gossiped their lottery outcomes to the provisioners, a winner is selected that can propose a pre-block. In case no nodes participate in a certain round the default block generated by the provisioners will be used. The big benefit of how SBA* combines sortition with gossip is that nothing needs to be known about the stakes, identity, or balances of the candidates, whilst still allowing for an audit of candidate’s honesty. The likelihood of a winning sortition outcome depends on a weight correlated to the amount of DUSK committed by a node. Proof of blind bid (SBA*) renders it statistically and economically disadvantageous for an actor to attempt bad behaviour, since he would risk losing his stake.

Rewards
In addition to finalizing a block onto the chain, Notaries are also responsible for a secondary procedure which generates the block rewards through a set of coin-base transactions, essentially minting new DUSK. This new DUSK will be sent to the address of the Block Generator(the successful lottery candidate). Provisioners do not gain their reward by winning sortition, but rather gain a fixed ROI at the end of a block. This ROI is also a coin-base transaction and is awarded to all provisioners, not just those who took part in this specific block committee(those performing VVN operations).

Counterintuitively, the rewards paid are inversely proportional to the staked amount (i.e. bigger stakes get proportionally less rewarded, in respect to smaller stakes). This measure is novel and to our knowledge not a viable option outside of the Dusk Blockchain. The motivation is twofold. Together with preventing the ‘’rich get richer’’ scheme, the intention is to create a counter position between power (intended as the capability to influence block generation by being selected as part of the Block Committee) and money (intended as the financial benefit acquired from running Provisioners). Considering that SBA* is already protected from Sybil attack by making it probabilistically disadvantageous to dilute a stack into several balances, similarly, by reversing the proportion between rewards and stake, the system prevents financially motivated participants to benefit from organizing themselves into few Provisioner pools at the expense of decentralization. Centralized pools are in our opinion a highly undesirable property of a good network.

The block rewards, together with the provisioner’s ROI, will form the DUSK network’s inflation rate. You can read more on the DUSK network’s economy in upcoming articles focused specifically on how the whole network will operate economically. However, incentives will align with decentralization and early adoption.

In order for this 100% anomine transaction to occur, should both use the same DUSK technology? For example, I use Dusk as an email service, I send an email, will the message be 100% anonymous until I reach the recipient?

A lot of technical information, many strong people in cryptography. Honestly, it is very difficult to understand the technical description of the project, but this is for those who do not understand. Cool project.
