What is Pura? | Beginner’s Guide

While every cryptocurrency would argue they’re trying to make the world a better place, Pura reserves 10% of every block reward to do exactly that. “PURA is the world’s first socially and environmentally conscious cryptocurrency programmed by protocol design to contribute up to 10% of its mining rewards to the common good.” What exactly is the ‘common good’? If you hold Pura, you’ll help decide within their decentralized autonomous organization or DAO. Based on Dash’s open source code, Pura is a decentralized cryptocurrency “run by the people for the people.”

Pura Planet

The creators of Pura envision a world where the popularity of cryptocurrencies make it nearly impossible for governments to effectively collect taxes. They believe the 10% set aside can help fund the necessities of society, such as roads, schools, and education. Before that day comes, the coins and DAO will fund and track “sustainable, environmental, and social projects around the globe.”

Pura Planet

Ultimately, the DAO would not only want to fund charities but bring the charities onto the blockchain. There are numerous charities with egregious overhead costs and corruption. “By getting charities, causes, and projects onto the blockchain, users ensure that contributions get tracked, the spending of funds is transparent, and fund recipients are held accountable to the community. In this way, the need to simply trust a nonprofit or prosocial cause based on good faith alone is no longer necessary.”

Target Audience

Pura, Spanish for ‘pure,’ was named with Latin American markets in mind. Given the recent examples of hyperinflation, cryptocurrencies can serve as a relatively safe store of value in Latin American countries. There are also numerous workers sending money back home looking for a low fee alternative.

However, it seems the community still has work to do penetrating these Latin American markets. It’s interesting to see Germany, USA, and Canada holds the vast majority of wallets.

Pura Wallets


The network’s features exist on top of a network of masternodes. You can run a masternode by purchasing at least 100,000 coins. At the beginning of 2018, that would cost about $37,000 dollars. These masternodes, due to their large investment in the network, are provided special rewards and abilities. First of all, they receive 60% of all block rewards. Second, you can easily deploy new features through masternodes. For more decentralized coins such as Bitcoin, new features require consensus across a large group of miners. While having masternodes sacrifices some level of decentralization, it’s believed that due to their investment, they will act in the best interest of the network. Finally, masternodes help run important features such as PrivatePay and InstaPay. You can check out a video of how to set up a Pura masternode here.

PrivatePay and InstaPay

As Pura is based on Dash’s codebase, the masternodes offer similar features. PrivatePay allows you to send money semi-anonymously. Instead of your coins going directly to the recipient, they first go to a masternode. The masternodes then start trading the coins around to obfuscate the history of the coins. A masternode then eventually sends your coins to the intended recipient.

InstaPay is similar to Dash’s InstantPay, but it’s presumed Pura’s transactions are so fast there’s no time to fully spell out the word instant. Rather than wait for confirmation on the blockchain, InstaPay is the processing of sending your coins to a masternode that locks the funds to prevent double spending. The masternode provides confirmation within seconds that the transaction locked in. The masternode then adds the transaction to the blockchain eventually. The InstaPay feature is especially useful for merchants who don’t want people waiting around for blocks to be mined.


Pura provides several incentives for merchants to accept the coin. As of February 1, 2018, they have 58 merchants signed up around the world. Through a process called “Proof of Adoption,” Pura will reserve a certain percentage of block rewards for partners accepting Pura as payment. These rewards will go into effect in the third quarter of 2018. In addition to block rewards and money savings on credit card processing, the team also believes people will support “brands with a good cause.” By using the network and increasing the value of the coins, users simultaneously increase the value of the 10% set aside to make the world a better place. If you’re interested in joining the merchant network, you can find more information here.


Pura mining uses the X11 algorithm with blocks on average every 1.5 to 4 minutes. Each block rewards 25.16 Pura. The team developed code to create the “Fair Mining Network Effect”. They’re trying to combat the issue of mining pools jumping around to different coins based on what coin is the most profitable to mine. These “jump and dumps” are bad for both network and price stability of the coin. As a countermeasure, Pura uses a “retargeting algorithm known as DeltaDiff” to readjust mining difficulty based on the average time taken to find blocks over the last 24 hours. This smoothing eliminates the negative effect and much of the incentive for large pools to jump in and out of mining.

Similar Coins

Of course, Dash is the most similar coin to Pura. However, Pura is the only coin with block rewards dedicated to charity. Dash requires 1000 coins to become a masternode. At the beginning of 2018, this would cost you close to half a million dollars. There is also only 22 million Dash in existence with 4666 masternodes locking up a significant portion of the coin supply. This system allows only 2.9 million Dash to be in circulation. Pura, on the other hand, requires 100,000 Pura to become a masternode. With 350 million Pura in existence, a greater proportion of coins can still move around the network.

Coin Supply and Sustainability

There are currently over 173 million Pura circulating with a max supply of 350 million. On average, 1550 blocks are mined per day. After a new update, 10 Pura will be released from each block with the following distribution:

  • 5.16: Full Masternodes
  • 2.00: Miners
  • 1.00: Proof of Acceptance
  • 1.00: PuraPlanet
  • 0.44: Governance
  • 0.40: Common Nodes

Pura Team and Progress

The team consists of over 20 members and is led by Vincent Fullerton.

Pura Team

Just recently, the team formed a partnership with BitXatm to let people buy PURA with cash and withdraw cryptocurrency in cash. The team continues working on the possibility of a Pura debit card as well.

Trading History

After launch, Pura quickly rose to over $1 per coin. After a retracement, the price has hovered between 30 and 70 cents. Its price is not reliant on the release of a new feature but simply the level of adoption and volume they can start to achieve. The vast majority of blocks currently have no transactions. With an increase in price and thus an increase in block reward value, you could then see Pura Planet start to make an impact.

Where can you buy Pura?

Coinexchange and Kucoin account for the vast majority of Pura volume with a Bitcoin pairing.

Where can you store Pura?

You can store coins in the Pura Aurora wallet available for download here. With Aurora, you’ll automatically receive all features and updates. The developers will release a mobile wallet at some point in 2018.


While Pura is a coin clearly still in its infancy, it addresses several key issues in the cryptocurrency space. First, the InstaPay provides instant settlement for merchants. People won’t wait around for block confirmations and merchants don’t want to lose money on an unconfirmed transaction. Second, they provide a level of anonymity in a time of increasing government surveillance. And finally, they take a look at the big picture and the issues we as a global community should come together and solve. Their DAO for the common good is an interesting experiment into the efficacy of a decentralized charitable organization.

Just as expected in my previous analysis BIT COIN Hit the 23.6% fibo and returned with a sharp spike
Now thats what am talking about
Well i believe technically and fundamentally we coming back up from the dead as we can see alot in the market
1. the G-20 FSB surpising gave us a boosst in their rejection to exchange regulation
2. weve so long surpassed the FUD in the market and most investors are pumping back in and i mean huge investors
3. market cap dominance increased from 200k+ to 350k+ thats a fucking growth guys
4. ITS BITCOIN 0.82% BABY THE KING OF the market
5. Cheers folks and let the ride begin
technically am waiting form bitcoin 0.82% to surpass the 10k mark and close right above it that would be the breakout am aiming for and when that happens am ALL IN this doesnt mean i am on a pause i bought a few bitcoins 0.82% @ the 8k mark th 2.44% e 6k mark and currenly still buying and HODLING cause i believe in it and you only loose when you sell


What is Abra? | An Investment App on the Litecoin Network

What is Abra?

Charlie Lee, the creator of Litecoin, has long teased a “huge unexpected surprise” for Litecoin. The surprise has arrived in the form of a new app from Abra. The app allows people to invest in 20 cryptocurrencies and 50 fiat currencies through the use of Bitcoin and Litecoin smart contracts.Not only can you invest in the 70 different assets, but trading between them is feeless and nearly instant.ice_screenshot_20180321-105208.png

How does it work?

Here’s an example of how to use Abra. Imagine you deposit $1000 of LTC into the app and want to trade for some exposure to Stellar’s price at $0.25. This creates a transaction on the Litecoin network that requires multiple signatures, like that of a smart contract. You sign the first half of the transaction to Abra and lock up your LTC at the trading price. If Stellar doubles in price relative to LTC, you would now have double the LTC. Then, you can have Abra sign the second half of the transaction. This would unlock your LTC and send your profit, resulting in $2000 of LTC in your wallet.

Abra App

At no point in this process would you ever own any Stellar coins. It would not be possible to send Stellar from Abra to a Stellar wallet. You are simply providing yourself market exposure to the price changes of altcoins. Abra creates a synthetic currency that follows the price of Stellar, but you are really engaged in Litecoin the whole time. You can invest in 70 different currencies, but never actually own them. You would own synthetic currencies that follow their price via smart contracts on the Litecoin blockchain. “In this way, Abra enables you to invest in multiple cryptocurrencies without creating a separate wallet, managing separate keys, or figuring out how to buy cryptos on an exchange.”

Synthetic Currencies

Liquidity of synthetic currencies won’t be a problem. Abra has successfully run these multi-sig contracts to “manage fiat, Bitcoin, and ether counterparty risk for over a year now with no service interruptions.” You can always trade for Bitcoin or Litecoin and send those coins to whatever wallet you like. In the US, you can also liquidate to fiat currency and send money to your bank account.

Abra can guarantee these smart contracts to their users by hedging their users’ positions. To hedge your trading positions, Abra performs “a combination of buying and selling cryptocurrencies with different exchange partners.” Their hedging provides no risk to the users or Abra. Their profit comes not from hedging but on the difference in price when you perform your trades.

Building on the Litecoin Network

Up until recently, Abra created smart contracts related to synthetic currencies on the Bitcoin network. However, they now plan on using the Litecoin blockchain for the majority of transactions.

“Abra has chosen Litecoin as the primary asset class for our investment platform although we now have the ability to move users between Bitcoin and Litecoin contracts. We chose Litecoin after a long and thorough research process to determine the asset class that met our criterion: secure, safe, scalable on-chain and off-chain, low mining fees, and preferably with adherence to the published Bitcoin core roadmap.”

Abra determined the future of their business can rely entirely upon the Litecoin network. Unlike other coins, Litecoin is free of hard fork drama, network outages, and spikes in transaction fees.

Abra believes that “Bitcoin will always be slightly more secure than Litecoin due mainly to its smaller block size – many refer to Litecoin as digital silver vs Bitcoin’s digital gold. But this small security tradeoff means lower mining fees and more on chain scaling for our users. We believe that Litecoin is the best choice today for these contracts.

Not only are Litecoin’s fees lower than Bitcoin’s, but the latest Litecoin Core update lowers fees even further. Average transaction costs could potentially be less than 1 cent.

What does this mean for Litecoin?

Abra dramatically reduces the complexity of investing in multiple cryptocurrencies. Users outside of the US interested in the investment platform can get started by first obtaining Litecoin. If Abra is able to attract a significant amount of users, this could drive demand for Litecoin. On the supply side, the numerous smart contracts on Abra will lock Litecoin away reducing the circulating supply of LTC. Finally, Abra’s choice adds credibility to Litecoin. Out of all the competitors such as Ripple, Ethereum, or Bitcoin Cash, Abra’s research showed Litecoin to be the best option.


How to use Abra?

To get started, first download the app here and write down your private keys. Abra is a non-custodial wallet so you have access to your own funds at all times.

Then using an American or Philippines bank account, American Express card, Bitcoin, Litecoin, or Ethereum, start funding your wallet. Once you add funds to your Abra wallet, you are ready to invest in any of the 20 available cryptocurrencies.

Final Thoughts

Charlie’s ‘big surprise’ might have been somewhat confusing at first, but there is no doubt Abra is nothing but good news for the future of Litecoin and its applications. Most coins are still looking to be added to new exchanges. In the case of Abra, the new exchange is added to Litecoin.

What is Enigma? A Beginner’s Guide to Secret Contracts and Off-Chain Scaling

What is Enigma?  

Enigma is an off-chain network meant to complement blockchain networks by providing secondary-layer data storage and computation.  The protocol will offer privacy and scaling solutions to any blockchain program that uses it, as data offloaded onto the Enigma network will be both private and freed from on-chain network congestion.


Secret contracts will be the butter to Enigma’s privacy bread.  They’ll be to Enigma what smart contracts are to Ethereum, and they’ll allow developers to build end-to-end decentralized applications that center on confidentiality.

How Does Enigma Work?

Enigma is blockchain interoperable and agnostic, and it will serve as an extension to conventional blockchain platforms for off-chain computations.  Code is processed both on the blockchain, where it is public, and on Enigma’s off-chain network, which is private.

To ensure that data remains secure, data can be encrypted before being sent to the network and this off-chain layer is responsible for distributing this data across Enigma’s nodes and keeping it private.  The blockchain’s public ledger only stores references to this data to provide proof of storage, but none of the data itself is public–it remains obfuscated, private, and split-up on the off-chain network.

Off-Chain Ecosystem: MPCs and DHT

To give you an idea of how this will work, Enigma is looking to use secure multiparty computations (MPCs) and an off-chain distributed hash-table (DHT) to ensure data privacy.  Don’t get too caught up on these cryptic phrases.  Basically, the MPCs distributes data between nodes on the network, splitting the encrypted information into separate pieces to ensure its safety.  The DHT, then, is responsible for storing this data in an off-chain database.  We can look at the MPCs and DHT as two halves of the same whole.  The DHT stores the data while MPCs are responsible for handling and retrieving it, while both ensure that the data handled remains completely private.

Enigma structure

Think of it like a puzzle.  Each node holds a piece to this puzzle, but each piece is useless without all of the others.  Moreover, the nodes’ operators don’t know the picture that all of the pieces make.  The user accessing Enigma to store her data, however, does know what the picture is, and with it, she can retrieve all of the pieces to reconstruct this picture when she wants.

Get the picture?  The puzzle pieces are the values that nodes store for the encrypted data.  These values derive from the data’s private key, the picture needed to verify that the puzzle pieces are yours.  Without the private key, you cannot access every piece of the data necessary to recreate the whole.Enigma nodes

Thus, all data “is split between different nodes, and they compute functions together without leaking information to other nodes. Specifically, no single party ever has access to data in its entirety; instead, every party has a meaningless (i.e., seemingly random) piece of it,” the project’s whitepaper states. Unlike Bitcoin’s nodes, not every node is responsible for storing information sent to the network.  Instead, Enigma’s network reduction technique selects nodes for any given project based on its performance ability and reputation, ensuring that only the right nodes take on a task based on its computational demand and that the network is being optimally utilized.

Node operators will receive fees–not mining rewards–for their efforts, as both computational and storage fees will be applied to network transactions to incentivize operators to provide computing resources.  To keep them honest, full node operators must make a security deposit that they risk losing if they act up, the Enigma whitepaper explains:

“To participate in the network, store data, perform computations and receive fees, every full-node must first submit a security deposit to a private contract. After each computation is completed, a private contract verifies correctness and fairness were maintained. If a node is found to lie about their outcome or aborts the computation prematurely, it loses the deposit which is split between the other honest nodes. The computation is continued without the malicious node (e.g., by setting its share of the data to 0).”

To wrap this section up, we can see Enigma serving two crucial functions for the blockchain realm:

Privacy: You’re probably sick of hearing this one–and yes, it is probably redundant to hit on it again–but this core feature is what Enigma is all about.  With Enigma, users can enjoy the full-proof certainty of an immutable public ledger (the blockchain) with the security and secrecy of an off-chain, encrypted storage option (Enigma).  Say, for example, a university wanted to record health issues with its students on the blockchain without revealing the ailments that plague each student.  With Enigma, they could keep a record of each condition recorded in the survey without revealing which student has what.  A comprehensive record of the survey and the conditions recorded are public on the blockchain, while each individual’s input and information are held privately on Enigma.

Storage/Scalability: Enigma can likewise be used for off-chain storage, whether this data is encrypted or not.  Thus, Enigma presents an off-chain storage option and a scalability solution, for it can be used to process heavy/intensive computations that are still publicly verifiable on the blockchain.

Catalyst and Data Marketplace

As we briefly reviewed, Enigma employs secret contracts that allow developers to create decentralized applications that focus on privacy.  Our university illness survey, for example, is one such use case for a secret contract dApp.  Others run the gamut from voting applications, to company financial audits, to identity management.

One such use case, a data marketplace for trading, is already live on the network.  Catalyst is the first dApp built on Enigma, and it makes use of a marketplace where users can curate, share, and swap data to build crypto investment strategies.  As the Catalyst whitepaper puts it:

“The main goal of Catalyst is to serve as a one-stop shop for developers (or quantitative traders) who are interested in developing trading strategies that operate in the expanding domain of crypto-markets. Developers can utilize the myriad of data sources that will be made available through our platform, and will be served through Enigma’s peer-to-peer data marketplace protocol, to build their models, back-test them according to historical data, as well as put their strategies to the test in a simulated or real trading environment. Over time, Catalyst will also serve investors without coding skills, creating If This Then That (IFTTT) for developing investment strategies.”

Enigma’s general data marketplace will serve the same function as Catalyst for a plethora of industries and use cases.  Data for anything from healthcare institutions to tax records could be compiled on the marketplace, and the application/usability of this data is only limited to the imagination of those who choose to use the marketplace.

Enigma Team and What’s to Come

Enigma’s team is replete with MIT-connected individuals.  It consists of MIT Lab and MIT Sloan fellows and seasoned software engineers.

Enigma team

Guy Zyskind, Enigma’s CEO and cofounder, has more than a decade of software development experience with an M.S. from MIT, was a former MIT Media Lab research assistant, and taught the first ever class on blockchain at MIT.  Can Kisagun, the project’s CPO and other cofounder, graduated from MIT’s Sloan School of Management has experience with a handful of tech startups, and worked at McKinsey & Company as a business analyst after completing his MBA.

The project is also vetted by a list of impressive investors, including Floodgate, Flybridge Capital Partners, the Digital Currency Group, and (unsurprisingly) MIT.

As for Enigma’s roadmap, there’s no fully fleshed-out infographic you can direct yourself to or trello board to keep track of the project’s developments.  The team does keep a fairly active Medium, and at the time of writing, the biggest news is the upcoming release of Enigma’s data marketplace to complement Catalyst.

Enigma’s Competition

You may be thinking that any and all privacy coins are in the competitive arena for Enigma, but privacy coins are focused on transaction privacy, while Enigma’s raison d’etre is data privacy–similar concept, different end game.

There are a few projects that are building data-driven marketplaces (see IconomiCindicatoriExec RLC), but the first two lack the off-chain privacy component that Enigma offers and iExec’s main focus is off-chain cloud computing for dApps. Bluzelle is focused on data management, but it also lacks Enigma’s off-chain approach as well as its data marketplace.

Keep Network may be the closest thing Enigma has to a competitor, but it’s still in its infancy and doesn’t have (to this author’s knowledge) any plans for a data marketplace of dApp development.

Enigma Trading History

Enigma reached a peak of just over $8.20 on January 10th, only to see a steady downtrend back during the January-February crash.  As of this writing, it’s ranked 88th on CoinMarketCap and has been floating in the ~$2.50 range.

Where to Buy Enigma

Enigma’s dominant markets are on Binance, Huobi, and Bittrex, and you can trade it for both BTC and ETH on all three of those exchanges.

Where to Store Enigma

Enigma is an ERC20 token, so any Ethereum compatible wallet (e.g., Ledger Nano STrezorMyEtherWallet, MetaMask, Parity, etc.) has you covered.

Final Thoughts

Enigma promises to offer two much-needed solutions for data management/storage on the blockchain: privacy and scalability.  With Enigma, secret contracts will allow users to keep sensitive information underwraps while also have the reliability of a blockchain network to validate this data.  In addition, developers can use Enigma to offload computation-intensive data on to Enigma’s off-chain network, giving blockchain platforms a scalable storage option and alternative resource to process data.

On top of both of these solutions we have Catalyst an Enigma’s data marketplace.  The first providers traders with useful tools to optimize their investing choices, while the latter could provide a comprehensive, secure marketplace of various data that individuals can consume or contribute to with the privacy and integrity of the Enigma network.

It’s rare to come across such a unique project with a dedicated, vetted team striving to make conception a reality.  If this reality comes to fruition, there’s no telling what Enigma’s secret contracts and data marketplace could bring to the crypto-sphere in the years to come.

“Blockchain is the real deal”: JP Morgan Unveils Report on Crypto’s Economic Advantages

JP Morgan Looks to Crypto’s Future with Optimism

In a recent report entitled “Unlocking Economic Advantage with Blockchain: A guide for asset managers,” JP Morgan makes the case for blockchain’s use in legacy business and asset management, which includes the bank’s take on blockchain’s adoption timeline.

“There is a growing realization that distributed ledger technology — popularly known as blockchain — will bring a radical shift in the way we think about financial assets and the way the financial industry will operate in the future,” the report begins.  Co-authored by management consultant Oliver Wyman, the writeup “[argues] that asset managers need to get off the sidelines and take the initiative to understand and embrace blockchain.”

As such, JP Morgan presents “a guide to how the technology may evolve, the impact it may have on asset managers and the action they can take.”  The first section of this guide details “Four Anticipated waves of blockchain deployments,” which are:

Information Sharing (2016-2019): In this stage, blockchain technology is used to store and share data, either within a single organization or between multiple organizations.  Blockchain will be tested in current working environments for proof of concept and feasibility of use cases.

Data Solutions (2017-2025): At this second phase, JP Morgan sees blockchain being integrated into business solutions to foster an environment for storing and managing data.  This integration will allow entities to reduce operational friction and improve existing infrastructure. When user interest and confidence is high enough, blockchain platforms will move from working alongside existing infrastructure to replacing it entirely.

Critical Infrastructure (2020-2030): Now, blockchain adoption is at full throttle.  At this point, it will be “adopted by market participants as [the] main infrastructure for critical functions.”  This could include replacing the outdated asset, payment, and/or transaction infrastructure and setting a new business standard for efficient data management.  Certain iterations of the technology will still be centralized at this point, though, for the convenience of access rights, deployment, standards, etc.

Full Decentralized (no date forecasted): The era of a truly decentralized economy.  Blockchain would replace certain centralized models, infrastructure, and systems with a decentralized solution.  This means completely peer-to-peer digital asset exchange and a legal framework for overseeing asset ownership and transfer using blockchain technology.  In essence, blockchain and cryptocurrencies become so ingrained in daily life that they become as normal as the internet or smartphones today.

The report continues to discuss the benefits blockchain offers to asset managers, including frictionless data management and solutions.  JP Morgan sees cost advantages, as well, wherein cutting out unnecessary processes and more efficient data aggregations mean lower costs for managers.  In the near future, the firm sees operations, IT, portfolio management, and finance sectors reaping the rewards of blockchain the most.

Additionally, revenue potential will increase for managers and businesses with access to improved data sources and liquidity mechanisms.

Towards the end of the report, JP Morgan implores managers “on the sidelines” to get off the bench and get into the game, claiming that those who will benefit most from this disruptive technology are those who get in early and work towards solutions.

JP Morgan Blockchain

Its authors also devise a “playbook” for chief officers of companies looking to work with blockchain, stressing the deliberation on the following:

  • Assessment of and education on the potential of blockchain in your organization
  • Guidelines for your organization’s vision and ambition going forward
  • Blockchain’s position on your leadership team’s list of priorities
  • An environment that fosters transformative approaches and innovative thinking within your tech teams
  • An external adoption/engagement approach

Some Takeaways

Back in February, JP Morgan said that cryptocurrencies could one day be integral to a diverse and well-balanced financial portfolio.  Last week, the bank publicly announced that cryptocurrencies pose a threat to its financial model.

Now, the institution is fully vetting the potential of blockchain to asset managers and business entities alike, a sea-change of sentiment from an organization whose CEO called crypto a “fraud” last year.  Recently, Jamie Diamon retracted this statement, and complementing his remorse, he endorsed blockchain technology for its wealth of potential.

This report serves physical testament to the increased interest in blockchain and cryptocurrencies we’ve seen over the past year.  Coming from one of the largest and most respected financial institutions in the world, the endorsement should further legitimize crypto to its skeptics.  As the arch of adoption continues forward and up, official reports like these, whether from the private or public sector, will be crucial for educating the public and dispelling misinformation and myths about blockchain and its abundant potential.

What is Nexus (NXS)? | Beginner’s Guide

What is Nexus?

Nexus is a peer-to-peer network that improves on the speed, scalability, security, and accessibility of current blockchain protocols. The project mainly accomplishes this through the use of a quantum-resistant 3D blockchain in combination with communication satellites in space. With this, Nexus founder Colin Cantrell is aiming to “decentralize the decentralization”, by taking it out of reach of any government control or mining pool monopolies.

Hold on to your hats, folks. This is one of the more ambitious projects out there, so let’s get right into it.


As at today 27 february, 2018. Nexus(NXS) is ranked 137 in the crypto market with a market cap of $102.88M and a trading volume(24H) of $2.40M, indeed a lot of prospective for this coin in the near future

In this Nexus guide, we’re going to go over:

Three Dimensional Chain (3DC)

Nexus uses, not one, not two, but three consensus mechanisms to form a three-dimensional blockchain. The team argues that having three different mechanisms in place reduces miner centralization and enables more efficient on-chain scaling.

Prime Channel

The Prime Channel is a Proof-of-Work channel. In this channel, miners search for 308-digit dense prime clusters through trial-and-error. Dense prime cluster mining is more ASIC-resistant than traditional hash mining. Therefore, even if you have just a CPU, you can mine on this channel.

Outside of cryptocurrency, the mining on the Prime Channel produces data that can be further used in prime number research for quantum physics.

Hashing Channel

The Hashing Channel is also Proof-of-Work but uses Hashcash instead of dense prime clusters. This is similar to Bitcoin’s mining algorithm except that miners search for SHA-3 (with Skein) hashes while Bitcoin miners find SHA-256 ones. The Nexus block hashes are 4x the size of Bitcoin block hashes.

You should use a GPU when mining on this channel.


The third and final channel uses Proof-of-Holdings to secure the network. This is essentially the same as the Proof-of-Stake consensus method used by coins like NEO. You earn newly minted Nexus coins (NXS) just by holding the ones you already have.

Four attributes determine what your return will be when you stake your coins:

  • Interest Rate – An annual percentage of your balance, this is the rate at which you receive new coins. This starts at 0.5% annually and increases to a 3.0% annual maximum after 12 months.
  • Trust Weight – This is an indicator of your node’s trust. It starts at 5% but quickly reaches its 100% maximum after just one month.
  • Block Weight – This attribute resets to 0% each time you receive a staking transaction. It then slowly climbs to 100% over 24-hours. If your block weight ever reaches 100%, your Trust Key expires and all your attributes reset. The reset trigger ensures that you’re continually working to maintain the network.
  • Stake Weight – The value of this is roughly determined by the average of your trust weight and block weight. The higher this is, the more likely you are to receive a transaction.

Nexus Hardware

Nexus has a three-pronged distributed telecommunications system to further decentralize the network.

Mesh Networks

Because the network provides three distinct mining opportunities, almost anyone around the world can run a node and participate in network security. All nodes in a mesh network work together to solve a block rather than compete against each other. This serves to distribute network data more so than other systems.

To take things further, Nexus may produce specialized antennas for you to purchase to operate locally based networks as well.

nexus satellite

Cube Satellites

Nexus has partnered with Vector Space Systems (Vector) to create a Low Earth Orbit (LEO) Satellite Network of nodes. The satellites, in combination with the ground mesh network, will host the Nexus network as well as any decentralized apps (dapps) built on top of it. Even more outstanding, the satellite network will provide a worldwide decentralized Internet giving service to those previously unable to access their own.

Ground Stations

The Nexus ground stations connect the mesh networks on the ground to the satellite network in space. They run the uplink/downlink operations including address endpoint route defining and ground-based caching. They also run their own instance of Daemon, the software component of the Nexus system.

Nexus Coin (NXS)

The Nexus coin (NXS) is the currency of the network. There’s no cap on the amount of NXS that will be minted. Instead, the coin has a 10-year distribution period in which 78 million NXS will be distributed until September 23rd, 2024. After this time, the supply will inflate each year by a maximum of 3% through the holding channel and 1% through the prime and hashing channels.

Nodes create blocks, on average, every 50 seconds, and an NXS transaction requires 6 confirmations. Currently, most transactions cost 0.01 NXS. However, once the 3DC is built and 10-year distribution is complete, transaction fees will disappear. Instead, the system will absorb the fees through inflation.

Nexus didn’t hold an ICO. Instead, the project has a Developer Fund that takes a small commission from mining rewards. This commission starts at 1.5% and increases to 2.5% over 10 years. Additionally, 20% of the block rewards are slotted for marketing as well as the production and launch of the Nexus satellite network.

Nexus Team & Progress

Colin Cantrell, also known as Videlicet, is the founder and lead developer of Nexus. He first named the project Coinshield (CSD) when starting in September 2014. The original code only contained the prime channel; the team added the hash channel in October 2014. In April 2015, the team rebranded to Nexus, and they added Proof-of-Holdings in July 2015.

Besides partnering with Vector on the satellite network, Nexus has also joined forces with SingularityNET to provide their 3DC architecture to the project’s decentralized AI network.

Moving forward, Nexus is releasing major updates following their TAO (Tritium, Amine, Obsidian) roadmap strategy. The releases include the 3DC, mobile wallets, quantum resistance, and the satellite network, among many other things.

Nexus TAO outline

Nexus is one the most ambitious, if not the most ambitious, projects in the cryptocurrency space. First and foremost, the project is attempting to dethrone Bitcoin as the top peer-to-peer currency. With the decentralized internet produced from its space mesh network of satellites, Nexus is also competing with Substratum.


Like most of the crypto market, Nexus was relatively quiet until 2017. During that year, the price rose from $0.026 (~0.000027 BTC) to $3.34 (~0.00087 BTC) by September. Shortly after, the price fell back down to about $1 before skyrocketing up to an all-time high of $13.33 (~0.0008 BTC) in January 2018.

This significant rise in price can most likely be attributed to the Vector partnership announcement in combination with the success of the entire market at that time. Since then, the price has drastically fallen, sitting at $1.75 (~0.00018 BTC) at the time of this writing. News of the SingularityNET partnership seems to have had no effect on the price.

The team hasn’t published a roadmap with exact dates, so it’s hard to make any price predictions for the immediate future. As with most cryptocurrency projects, though, important development releases should have a positive impact on the price. With the scope of this project, you should probably consider it a long-term hold.

Where to Buy NXS

You can purchase NXS on either Bittrex or Upbit with BTC. If you don’t currently own any BTC, check out our guide on how to buy some.

As mentioned early, you can also earn NXS through mining. Check out the Nexus mining page to download the miner that fits best with your strategy. As a reminder, you should mine with the Prime Channel if you’re using a normal CPU, and you should check out the Hashing Channel if you plan to use a dedicated mining rig like an ASIC.

Once you hold at least 1,000 NXS, you can stake to earn additional coins.

Where to Store NXS

Nexus has an official wallet for Windows, Mac, and Linux desktops. Although you can keep your NXS on an exchange it’s highly recommended that you move them to a wallet. You’re only able to stake your coins if they’re in a Nexus wallet.


Nexus is building a new type of blockchain with three separate mechanisms for securing the network. On top of that, the team is sending node satellites into space to create a decentralized Internet and network outside the control of any one entity. The overall mission is to create an improved Bitcoin with faster transactions, lower fees, and less miner centralization.

Nexus is one of the few projects truly addressing quantum resistance and other potential future issues. If these problems become as large as the team believes they will, and they can accomplish their lofty mission, Nexus may just be one of the few projects still in action 20 years down the road.
