Nxter News – May 2018 (III): The Surest Way To Make Your Dreams Come True Is To Live Them

May (III)


Welcome, dear Nxters and other followers!

Our dream is a world in which society is all around better, more accountable, more connected, and more convenient – all powered by distributed ledger technology: blockchain. We are living out our dream of a world in which ecosystems of decentralized apps exist and our data is secure and untampered and our voting systems are reliable and immutable. Our dream has a long way to go before it comes to complete fruition, but every week we see progress. Yes, the world seems to have embraced ICO’s, but there is so much more to the technology than trading tokens that are pumped by (insert clueless celebrity here) marketing. Everyone can dream, but not everyone follows through on them. Perhaps you, dear reader, can be inspired by us to make the world better – or at the very least be inspired by our passion and knowledge to join us on our journey. Our journey is only just beginning and we might not know the path, but we do know the end.

Last week as we lived our dream, much happened – especially in the Meetup space, Lior wrote two articles that we summarized – one about the use of Lightweight Contracts and a second concerning Transaction Vouchers, videos were released, an Ardor based proof-of-concept DEX was presented to Binance, Ignis micro-messaging app FreeBird concluded their airdrop and ICO,  Bitswift talks about their new CASH token, and much more.

We welcome back our old readers and warmly welcome our new ones. We want our readers to stay up-to-date with the blockchain evolution and we also want our readers to keep themselves and, their data, as safe as possible. Become experts in the Nxt / Ardor / Ignis blockchain ecosystem. So lean back and learn about all of last week’s progress.








This week’s newsletter is put together by apenzl, Jose, James, and rubenbc.


  • Jelurida

As much as we are eagerly waiting for the reveal of the Nxt, Ignis and Ardor roadmap from Jelurida, which will be announced live in Korea this week, it has not been a boring week.

Much of the week went into attending conferences. Also, Lior expanded upon his introduction of Lightweight Contracts with more informative posts about these user-created smart contracts on Ardor. A presentation of a new feature that has been added to the roadmap, “Vouchers” was also explained in more detail.

Read more about this, in the “Development” section down below.

  • Binance – Dexathon

Last week we announced that community member Patoshi was going to demonstrate an Ardor based DEX to Binance, one of today’s most popular crypto exchanges. Binance launched a “Dexathon” to help them create a new decentralized exchange engine that will run on their own native blockchain: Binance Chain.

Patoshi stood up for us and offered them this:

wat u guys think…
seems real…

After the presentation, Patoshi warned us that a video of the seance will be coming:

it went well! many liked the demo of the reskin and kept thinking it was done by binance…. i have it recorded. i’ll process it and upload it.

Thanks for the work, and the demonstration in NYC!

xCubicle, a blockchain lab on Wall Street gives a proof-of-concept demo for the Binance DEX competition being held in 2018. The demo uses the Ardor blockchain platform to build out the decentralized exchange along with other features like crowdfunding to KYC restrictions.

  • Jaxx Multiwallet will Include Nxt, Ardor, and Ignis

Last week it was pre-announced that Jaxx will include support for our three favorite tokens!

Elizabeth wrote:

Update after the Decentral Cruise where they announced the new Jaxx hardware wallet will be released on July 1. Get ready because it should include Ardor, NXT and Ignis, I hoped for specific mention in the announcement but they didn’t mention included tokens. Let’s watch for more details.

A deep and long look at Ardor. The narrator believes Ardor is a good investment and goes into a thorough explanation as to why. This might not be shocking news for longtime readers but it is always good seeing the wider crypto-sphere confirm our beliefs with independent, unbiased analysis.

A couple days ago I put Ardor on your radar as a good buying opportunity, Today I wanna dive deeper and take a look into what ardor does and if it’s a good investment. Straight forward & easy to understand.

Build the tech and they will come – to Meetups! Last week was a busy week for the public-facing figures in Jelurida, Ardor Nxt Group, and the community. Oxford, Monaco, London, and NYC all were visited!

Here’s a recap of the action:

Jelurida at Oxford University, May 14th

Alberto Fernandez (almonte) wrote:

We had an amazing experience in the yesterday event. Some attendees from the University of Oxford had an idea. They want to setup an Oxford public node for experimenting and being part of the community. The issue is that they do not have funds so I came up with the idea that maybe it might appear some community members willing to lease their balance for them.

Are you willing to contribute leasing your forging power? Please let me know so I can synchronise everything, once everything is set up.

Although the current Ardor transactions fees are very low in terms of rewarding the nodes, the profits would go towards the society’s events, so not for profit of course. It is really interesting that they want to test a rasp pi 3 for forging and get some measures. Thanks! Once they configure their node I´ll let you know the address.

You can contact Almonte on the ArdorNxt Slack, or drop us a line in the comments field.

  • Consensus 2018

Elizabeth, the director of the ANG, attended Consensus 2018 in NYC.

Elizabeth updated the community along the way, in Slack

In case you missed it in another thread, I just set up a meeting with a man and his colleagues about smart city applications when I am in Arizona next month.

Right before that I connected with a man who wants me to speak at his meetup soon.

I met some really interesting people over lunch including some blockchain builder consultants that said our platform was on their radar and a CEO of a sharing community that wants to build a big blockchain project.

I’m going to try to give you a play-by-play so you will see how productive these events can be.

But maybe of more interest meeting @alex0909 and @gabriel. Here’s proof, I’ll try to grab a photo with Alex the next time I see him

  • Lior Yaffe in Medium – Lightweight Contracts Design

Jelurida has been very busy developing their new Lightweight Contracts concept. Lior wrote about the latest changes that he and the other devs at Jelurida have been at work on. This article does a good job of explaining the technical side of implementing and triggering Lightweight Contracts and goes into deeper detail on “Vouchers” and their usefulness and versatility – analogous to an invoice, but nowhere near as limiting in scope.

He wrote:

To summarize, the design of the lightweight contract feature is rapidly progressing. In the upcoming days, we will release additional examples of new contracts functionality which addresses real use cases, explains how transaction vouchers work, and how they can be easily integrated with contracts to unleash the full power of decentralized applications.

  • Lior Yaffe in Hackernoon – Introduction to Transaction Vouchers

If it seems like we are hammering you on the head with Transaction Vouchers, hey – thanks for noticing! This is a very useful and immediately applicable concept that Jelurida is being a thought-leader in. As mentioned above, a Transaction Voucher can be thought of as a secure invoice for payment that is easier to use than the current methods. Anyone who has tried to send funds to or from an external third-party exchange, like Bittrex, knows how scary and intimidating the process is. It may not be that hard, but it sure can look less intimidating and Transaction Vouchers are going to go a long way towards making such payments easier and more secure, such is the dream after all!

Lior wrote:

Think about transaction vouchers like an invoice. A request to pay a certain amount to a certain address signed by the private key of the recipient. The idea is based on the Bitcoin Payment Request proposal but using the rich functionality of Ardor/Ignis, we can do so much more.

The voucher itself is a JSON format, composed of the transaction json, transaction bytes and a digital signature of the transaction bytes.

Say, Alice wants Bob to pay her 100 IGNIS. She logs into the Ardor wallet using Bob’s account and sends payment as if she were Bob. Of course, she does not have Bob’s passphrase, so she cannot submit the transaction. Instead, she signs Bob’s payment using her passphrase and generates a voucher.

Alice then downloads the voucher and emails it to Bob.

Bob receives the voucher and loads it into the Ardor wallet. The Ardor wallet automatically verifies that the voucher signature is valid and that the voucher bytes are a correct representation of the voucher transaction JSON. After validation succeeds, the wallet presents Bob with the request, it shows Alice’s address as the recipient, the amount she wants him to pay, any attached messages and any other transaction parameters.

All Bob needs to do is validate the data, sign, and submit the transaction using his passphrase.


But vouchers are not limited to payments. They can be used for any transaction type supported by Ignis. For example Bob wants to delegate a poll vote to Alice. (…) Or, as another example, Charlie, a forging pool operator, wants Bob to lease his balance to his pool. Again he performs the leasing request on behalf of Bob, then sends a voucher that Bob needs to sign and submit.

  • Ardor Lite Update

Updates from the Ardor Lite project. The creator is accepting feedback on changes that you would like to see added to the Android app – and an iOS app is in development.

mrv777 wrote:

Version 0.8.4 of Ardor lite released to the Google play app store. Changes include:
• Korean added to translations (in time for the South Korea meetup)
• Loading splash screen added
• Clicking on coin exchange prices now loads that price and displays the max available at that price
• If <0.001 on coin exchange, says that instead of rounding to
• Fix decimal formatting for buy/sell in coin exchange
• Styling improvments
• Increased max amount of trades shown in coin exchange

If anyone has any more suggestions for Ardor Lite please let me know. I am trying to finalize version 1.0 for Android and iOS. Everything looks good on Android currently, iOS needs some styling tweaks

Anyone want to test on iOS?

  •  Weekly Reminder: Forge OR lease your forging power

Did you read that call for ARDR holders to support students by leasing their balance to them?

Nxter, if you are not forging, please consider leasing your balance to a hub like the above. By doing so, you do not just support a great project, you’ll also be securing your investment in the blockchain. Why? Forgers create all new Ardor blocks, confirm all child chain transactions, and secure the whole Ardor network.

Don’t you know how to lease your balance?

In the Client Dashboard, under your balance, click More Info

Select Account Leasing > Lease your balance to another account

Enter the account you want to lease your balance to

Calculate fee (it’s 0.1 ARDR). Lease Balance.

You can submit 2 leasing transactions just after each other and prolong the leasing period to 92 days. By leasing your balance you do not put your ARDR at risk – you can still use, spend, and move them as you wish. Your coins and your passphrase are not sent to the forging hub – it only gets the ability to forge with your balance.

To support the University of Oxford’s public node, contact almonte or leave us a comment.

Nxter Magazine’s forging account is ARDOR-NYJW-6M4F-6LG2-76FR5 – you’ll support our work.

Bitswift has a forging hub with payouts here.
And the good old https://ardorpool.tezzigator.com has payouts too.

Want to forge by yourself? Read more about the forging algorithm here, and don’t forget SegfaultSteve’s advise!

  • FreeBird 2.0 – Update

Last week the FreeBird team announced that their airdrop and ICO are complete! More FBC tokens can be had by frequent users of their new microblog platform.

Goodrain wrote:

Airdrop and 2.0 ICO is finished.

Freebird 2.0 is now available. In order to promote this decentralized microblog system, we launched dividends and active user rewards.

1. Dividends
All FBC (IGNIS asset:10901629157658360185) holders will receive 1% dividend every week. We have prepared 80,000,000 FBC for dividends.

2. Active user rewards
Every week, we will select up to 50 active users to send FBC rewards. Active users are those who publish messages on FreeBird 2.0. We have prepared 20,000,000 FBC for rewards.

The above activities will take effect from today until the end of the rewards.

  • Bitswift Child Chain Update

Last week Bitswift had the following updates, including their CASH token.

bitswiftbro wrote:

instead of focusing on how to build a better blockchain, we focus on apps that connect people to the blockchain
each app having some business aspect to it.. some purpose.

A practical guide to generating passive crypto token rewards on the Bitswift blockchain

Paul Busch

I am most excited for CASH token as we will be marketing it as a “digital currency” and plan to integrate it into future platforms. For example there is nothing saying we cant enable the decentralized marketplace, and have CASH being the primary currency for that market place. I have some other ideas in regards to gaming and CASH token, where we could have a gaming divison of Bitswift that focuses on developing VR content that utilize CASH token. (I am a big fan of VR). Actually I have been thinking quite a bit about using CASH token as the basis for an economy inside a virtual reality world. Where community members could visit to claim CASH tokens, I wonder how CASH could be used to influence player locations and interactions.

I feel volume will pick up as we continue to add more utility to the tokens. Our tech business is also getting an increase in amount of interest from our general business customers regarding crypto. Part of the reason we are releasing Bitswift.cash is so that these users can just enter our ecosystem through that platform which will act as an exchange on its own.
I think Bitswift.cash could also be used as a proof of concept for universal basic income on the blockchain.

Will users be able to trade cash for other cryptocurrencies?

Paul Busch
Yes there will be a market for CASH tokens on the asset exchange.
This is a platform that we support, so expect the market to have support.
Working on legals, business stuff, adding some stats on the CASH token market, testing, more testing, move flexepin service to production, release.

Distribution will happen through the bitswift.cash platform. Users have to claim cash token there to recieve it. Either that or trade it on the asset exchange. Each user can claim the same amount per day.

So the market will go live when we offically launch the platform. ETA… not sure.. it seems to take lawyers a long time to do things. I would hope that we have it publicly available within 30 days or so. That is of course if we are not finding any problems.

Bitswift cash is just one application on bitswift. It provides a use case example for how applications may use the blockchain.
Ardor already has AEUR, the euro gateway, so I am thinking Bitswift.cash will become the Canadian gateway. It should be relatively easy to hook up other payment methods like interac E transfer online, and even credit card for those users we really trust, such as our current business customers.

How many ppl are working on Bitswift with you?

Paul Busch
There are 2 core people doing the blockchain dev stuff, myself doing project management, then we have a few community members who do various things, such as making our reddit look nice for example. Then our tech business has 5 guys doing stuff, and we have admin (my wife) who takes care of all the paperwork. Mike (my brother ) manages all the bitswift.shop stuff. Hes doing a really good job with that, if you check out the products now everything is really nicely formatted and such, hes done that all.

  • What Is Action Coin?

Months ago we wrote about the Action Coin and their ICO. But apart from existing, many people do not know who they are or what differentiates them from thousands of other legitimate platforms out there. In short, they say they are a blockchain-based reward program that is built on Nxt, so there was an airdrop for anyone with a balance of NXT on the Nxt blockchain. We caution against using your Nxt passphrase to login to their site to check on your ACTN tokens as we do not know how secure their site is – use your account address if you want to check your balance – ALWAYS SAFEGUARD YOUR PASSPHRASE.

They wrote:

Action Coin is built on Nxt Blockchain technology

The first cryptocurrency, Bitcoin, was launched only nine years ago. Today there are more than 1500 known cryptocurrencies, and the number of coins is increasing every day. Many of these digital assets are tailored towards payments, but some offer much more than that.

On February 8th 2018, we cloned the Nxt Public Blockchain, thereby forming the basis of the Action Coin Public Blockchain. Our clone includes all of the wallets that were on the Nxt Blockchain when we took the snapshot, and 10% of the total Action Coin supply was automatically airdropped to all (more than 234,000) Nxt holders (as per the terms of the Jelurida JPL), at the approximate ratio of one (1) ACTN for every Nxt held on that date.

Nxter News – May 2018 (II): Life Can Only Be Understood Backwards; But It Must Be Lived Forwards

May (II)

Welcome, dear Nxters and other followers!

Progress is not always elegant or “picture-perfect.” Progress is often slow, painful, but ultimately greatly worth the momentary inconveniences of the growing pains. The computer did not change our lives in a day, it took decades for the technology to mature to benefit the average person. Then came the internet which exploded in popularity after only years. Now we have blockchain and ICO’s and cryptocurrencies and the like. America continues to, slowly, appreciate and regulate ICO’s and tokens like XRP and ETH – more ICO’s are planned for this year than ever before and we are at the forefront of this technological evolution! Progress is moving forward and learning these things – if this scares you, well, it should not, it should excite you! Last week we challenged you to spend an hour using the Ardor client. Did you do it?

We are not here to judge you, rather we are here to guide you through all this. Last week was eventful for the Nxt / Ardor / Ignis community. Jelurida released an intermediate roadmap, new videos, we warn you about filthy scammers, we reviewed the Ardor Blockchain Bootcamp course on Udemy and confirmed that you, yes you can become an advanced user of Ignis and Jelurida’s Ardor client. We bring you the latest info on the Triffic ICO, the latest Meetups that are happening  (and there are many), and much more!

We welcome back our old readers and warmly welcome our new ones. We want our readers to stay up-to-date with the blockchain evolution and we also want our readers to keep themselves and, their data, as safe as possible. Become experts in the Nxt / Ardor / Ignis blockchain ecosystem. So lean back and learn about all of last week’s progress.

  • Jelurida

Ardor Roadmap Updated

Lior Yaffe, co-founder, core-developer, and spokesperson for Jelurida, posted on Slack last week:

Ardor/Ignis roadmap update:
As promised I’m posting an intermediate roadmap update for Q2/2018 in order to update the community about the development progress. The release of the full products roadmap, including NXT, is scheduled for the Ardor Seoul Meetup and will take place on May 28th.

What we announce today is as follows:

Q2/2018 release:
• Asset, Currency, Goods specific bundlers
• Translation of wallet to 14 languages
• Lightweight Contracts Add-on – testnet
• Transaction Vouchers – testnet
• Java 9 support

The Pruning and Snapshots feature will be available on testnet in Q3 and on mainnet in Q4.

We are making good progress with the design and implementation, however, we must make sure everything works 100%, before we can go live with such an important and unique feature.

And so, https://www.jelurida.com/ardor-roadmap shows the following changes:

Changes in the roadmap. Former roadmap (on the left, from Google Cache). New roadmap (on the right, from jelurida.com)

What is this  “Transaction Vouchers” now? And where did the “Additional child chains launched on mainnet” in Q2 go?

We will have to stay excited until the 28th of May when Lior goes on stage in Seoul, but following the indicators and action going on on the chats and forums, it is not a delay that we need to worry about. Triffic, the first child chain ICO on Ignis is not delayed, the Transaction Vouchers concept is well explained by Lior in a video below,  and “Asset, Currency, Goods specific bundlers” looks like an addition that screams for getting more attention soon. If you recall the “0 transaction fees post” about custom child chain bundlers, you might have a hunch about what will be added.

At Nxter.org we feel nothing but confident and eagerly await the next two weeks.

  • Binance Dexathon – thanks for the pizza

Some weeks ago Binance announced a “Dexathon“, a coding competition with a $1M prize. The competition aims to create a new decentralized exchange (DEX) that will use its own native blockchain, Binance Chain.

Having launched the world’s first DEX, with the successful Nxt AE (Nxt Asset Exchange) online from 2014, some community members found it hard not to pitch in. One person that took matters into his own hands was community member: @patoshi.


giving an ardor demo…. lets see how it goes.

Elizabeth, director of the Nxt and Ardor Group (ANG):

I’m looking forward to talking with Patoshi this week at Consensus and looking at ways ANG can help.

There are so many opportunities for team work and support here in our community! @patoshi is working hard on many fronts. It will be fascinating to hear more about both his Meetups in NYC and his development projects!

Binance benefits from the Meetup they will sponsor. If we want the same attention we would need to find a way for Ardor to uniquely provide a benefit to them. (…) think on that while we wait :slightly_smiling_face:

  • Scam Accounts on Twitter

Lately, a lot of fake twitter accounts are appearing offering Ethereum giveaways. Jelurida has them, Nxter Magazine, nxtplatform, ardorplatform, ardornxtgroup, sazan have them. Ask yourself: would any of us give away free ETH? If it seems to good to be true, it is.

The fraudsters impersonate our profiles to promote their scams – it is not very brilliantly done, but we can see that they steal from some. Nxters, please BE AWARE!

One of the hundreds of scammer accounts. Blocked us, so we can’t them.

People, do not fall for it. Seriously. You do not send cryptocurrencies to accounts you do not know.  And Nxters, if you see fake Nxt/Ardor accounts, please let us know, and help us report them. Newbies are getting hurt by these scams!

HitBTC – Opened IGNIS/ARDR Deposits and Withdrawals

HitBTC opened Ignis and Ardor exchanges last week:

Hitbtc open deposit and withdrawal Ardor and Ignis

just checked hitbtc, both are available for deposit/withdraw

So they released people’s ardor and Ignis after 5 months? Can’t be.

Unfortunately they didn´t credited my IGNIS airdrop coins.

Help us hold them responsible!

Nxters, readers, other crypto followers – opening the wallets is great, but finishing the distribution of the IGNIS Airdrop tokens as promised should be accomplished too.

ChangeNOW – ARDR and IGNIS Enabled


https://changenow.io, Ardor and Ignis enabled.


Looks like its finally working (at least it provides the exchange rates which was a problem with IGNIS last month). If someone would like to test their service I would really appreciate it.

  • Triffic – ICO About to Start

The Triffic team updated the community last week about when their anticipated ICO is going to occur – June 4th is the announced date.

coinerz also wrote:

We are holding our ICO on the Ardor platform and eventually we will become our own Ardor childchain.

This is a fact, but there’s a huge reason why it doesn’t appear on the roadmap. That’s because the child-chain implementation timescale rests with us and not Jelurida.

As a company, we have several hoops to jump through before we are ready to implement the childchain.

We have our ICO, we have building and scaling our app. We have to build up the worldwide community and we have to ensure that what we create is compelling for as many people as possible.

This may take six months or less, it may take a year or longer – at the moment there are so many variables, it’s impossible to predict a timeframe, let alone one that is publically announced to fit in with another company’s roadmap.

My point to this is that the perceived slowness of new childchains is nothing to worry about. Good projects take time to do properly, but they are coming.

  • Generate and Get Paid with Vouchers, Using Ardor

In this video, Lior explains a new feature from Jelurida’s roadmap, “Vouchers”, to a captive audience in Oslo. In essence, “Vouchers” look like an easier way to create unsigned transactions JSON’s and send them to each other. You can do this with NXT and any Ardor child chain already, so what we are looking at might not a completely new feature but an optimization of the UI, and perhaps some new API’s.

In the video, Lior shows how to send a “Voucher”, consisting of a simple money transfer – in essence, an invoice for money owed.

If you want to send invoices today you can

1. Log in to any node, like nxt.nxter.org or ardor.nxter.org with the Payer’s account address.
2. Create the transaction and click ‘Advanced’ > ‘Do Not Broadcast’ > ‘Do Not Sign’ > ‘SUBMIT’.
3. Paste the ‘Unsigned Transaction Bytes’ or JSON into a text file or an email and send it to the Payer.

The Payer can now sign it with his passphrase and broadcast the transaction.

Or sign with NxtBridge OFFLINE tool or SigBro OFFLINE, and broadcast securely via the nxter.org website.

We look forward to learning more about the inbuilt “Vouchers” feature, which is planned for testnet in Q2/2018.

  • Blockchain Generator Based on NXT Clone Starter Kit

Building upon the backs of giants, one Farbod Saraf, announced his project CoinGenerator: an open-source command line tool which allows you to create your own Proof-of-Stake (PoS) cryptocurrency (a Nxt blockchain clone). A nifty and elegant idea – but remember, per the terms of the JPL, 10% of any tokens created are reserved for NXT holders.

Farbod wrote:

We wanted to create our own cryptocurrency to integrate into our product but soon we realized that there are not many resources to help to build an energy efficient coin. So we decided to create this open-source tool which enables you to make your own cryptocurrency with its blockchain in less than a few minutes: https://www.producthunt.com/posts/coingenerator

Why your own crypto? Just a few use cases:

  • Build a local currency for your city
  • Build an asset management system for your company
  • Build an internal bonus system for your employees
  • Integrate blockchain to your existing product (e.g. to create a gamification ecosystem for your app) – or just play around for testing.

PS. For every cryptocurrency being generated via this tool, 10% of the tokens go back to NXT holders (due to NXT JPL license).

Come share this special moment with us on Product Hunt (we’re trending!) and tell us what you think about CoinGenerator.

We’ve made this [MOTIV currency] using the CoinGenerator: https://motive.network/
So basically 10% of the MOTIV coins will go to NXT holders. Same for any other projects made via this tool.

  • How to Issue an Asset on Ardor in 5 Mins

In this article, the author guides you through step-by-step how to create an asset on Ardor using the Asset Exchange. It really is that easy and simple to do!

The author wrote:

Ardor is touted as the leading contender in the BlockChain as a Service space and with good reason. It is more user friendly for individuals or business to get started with as everything can be done out of the box from within the official wallet without stress or worry.

  • Business.com – 5 Industries Primed for Blockchain Disruption

This article present use cases for blockchain and Ardor is highlighted as the premier example of Blockchain-as-a-Service (BaaS).

They wrote:

Blockchain as a service

Many blockchain projects have tried different methods to fix Ethereum’s scalability issue, including Ardor, the new BaaS that offers data cloud storage, customizable monetary tokens, decentralized trade, encrypted voting and messaging, and a local marketplace. Where Ardor is notable is in its unique method of tackling blockchain bloat.

Ardor actually consists of two blockchains: a parent and a child. The parent chain, Ardor, takes on the brunt of the processing functions, while the child chains pay a fee to have their transactions processed. Older transactions can then be pruned, with certain nodes opting to act as archives for obsolete transactions.

Ardor has already launched its first child chain, Ignis, with more to come, promising a cost-effective and secure solution for companies to piggyback on a full-fledged blockchain as opposed to building their own from scratch.

  • Bitscreener – Innovation and Enthusiasm Abounds in Crypto, but Where is the Trust and Experience?

ICO’s are exploding and it seems that everyone is trying to get in on this “hip” scene. But there are few trustworthy entities out there and the phrase “Caveat emptor” holds as true as ever. Jelurida continues to buck this trend by bringing maturity and experience to the blockchain space as there is a direct legacy between 2013 and the creation of the first 2.0 blockchain, Nxt, and Jelurida now. With years of experience and mature technologies, Jelurida is a lighthouse of stability in a cluttered and crowded sea of “bandwagoners” seeking to make a quick buck by throwing a celebrity and a flashy marketing campaign.

They wrote:

Jelurida, the company which owns the NXT Blockchain [IP rights], is another one that has history of experience having been around since November 2013. Jelurida is also expanding its growth with the experience it has garnered since taking up NXT, by building the Ardor Blockchain.

Both of these products from Jelurida are suitable for companies, but they differ in that NXT is designed for the private sector, and the public sector where as Ardor has more use-cases in the business sector. This indicates that the company has taken the time, and garnered the experience, to decide what is right with their Blockchain solutions in different circumstances.

Jelurida is strategically maintaining and developing for both Nxt and Ardor as both of them have common selling points, like PoS, java, APIs, and other such working features.

It has behind it trust, as well as experience, something that is vital, but mostly lacking from the new wave of cryptocurrency businesses.

  • Coinbureau – NXT Coin Review: A Deep Dive into the Original Blockchain 2.0

This article is a well-done overview of NXT. From the creation of the Nxt blockchain to the definition of Blockchain 2.0 to the present day: this article highlights that although Ardor is technically Nxt 2.0, the original coin and its blockchain are still around and still worth keeping tabs on.

They wrote:

In Conclusion

Nxt was the original proof of stake coin, and is considered by some to be the realization of blockchain 2.0 – an improved version of Bitcoin built with Java.

It has lost its luster over the years, and other blockchain 2.0 technologies have stolen its limelight, but it is still a powerful and unique blockchain. With the development of Ardor, the Jelurida group hopes to restore its grip on blockchain 2.0 technology, with an improved and scalable solution.

You can learn more about Nxt here or get involved in its active community of enthusiasts and developers here. You’ll also find a download for the Nxt client, as well as an online demo to show you how the client functions before you download.

  • How I Created a Cryptocurrency that Rewards you For Doing your Own Tasks

From the same author as the previous entry, this article walks you through the creation of Motive, a cryptocurrency that rewards you for “getting things done” (GTD). An interesting, but long, read.

Creator: On the left, the wallet of the cryptocurrency created, and on the right, Kanbanote!

From the creator:

[With] ERC20 Tokens, the only problem is that I would have to pay fees for each transaction which makes sending 1 MOTIV per task done, a very costly action for the users! Also ERC20 uses Ethereum that uses the proof of Work consensus which is using a lot of electricity power! That is why I went for the PoS solution. (…)

I then found NXT. After more researches, I even found the NXT Clone Starter: https://bitbucket.org/Jelurida/nxt-clone-starter. There was even a video tutorial made by the team. The only con which is actually good for adoption is that 10% of the new coins will be given to the NXT holders! (…)

Now the cryptocurrency works. I had to integrate it to Kanbanote. (…) I always try to improve the user experience, so this Cryptocurrency should not interfere with a normal usage!

Ardor Blockchain Bootcamp Reviewed or: How I Learned to Stop Worrying and Master Ardor


What a great feeling it is to challenge yourself and accomplish something that you have been meaning to do so for a long time. As an editor of Nxter for the past year, I have written much about the advanced functionality of Ardor and yet my dark secret until last week was that I had never truly explored the advanced functionality of Ardor. Sure I could parrot the concept of Phased Transactions but I have never created my own approval model. I could highlight the Asset Exchange functionality of child chains like Ignis, yet I have never issued my own asset or even bothered to see what assets are out there.

I acted like this guy:

But I really was like this:

I have that exact shirt!

But the plot twist here is that I decided to change all of this. I conquered my fear and my inadequacy and dammit I sat down and went to the Ardor Blockchain Bootcamp. Herein lies my review, and my experience.

SPOILER ALERT: the course is very well designed and has something to offer anyone, no matter their experience level and I highly recommend it to anyone who desires or wishes to be able to explore the advanced functionality of Ardor in a structured and guided manner. Yes, this course costs actual cash money, but I fervently believe that this course is a bargain for anyone who completes it as they are going to have a very solid understanding of many, but not all, of the functionality of the Ardor client.


What is Udemy?

For the uninitiated, Udemy is a website full of online courses, designed by knowledgeable and passionate people that are structured to teach you about specific courses. I needed to register an account with them to take this class.

Once I had passed the paywall I was in. It was comforting to read that this course ASSUMES NO PRIOR KNOWLEDGE. Nothing about Nxt, the Airdrop or anything like that. No special programming knowledge is required is plastered in the course description. While I personally enjoy programming, I get how the average plebian might be relieved to read this. This entire course is just using the Ardor client and the Ardor testnet. Oh yeah, I learned how to use the Ardor testnet too! #Exciting


Part 1: the Basics

The headphones are on, the calming lights are activated and I am ready to do this. The very first thing I am treated to is a calming video of the creator, Eric Funk, explaining to me what I am about to learn and what the objectives of this course are. I am excited to gain real-world, hands-on experience with the advanced features of Ardor.

What lies ahead of me is creating my own cryptocurrency, setting up my own poll using the Voting System, creating my own Asset on the Asset Exchange, issuing my own currency and more. I am actually knowledgeable about everything in part one, as is likely the average user. The first videos are likely very skippable for most Nxters – chances are that most everyone already has the Ardor client installed and an account created. No worries if this does not apply to you.

Like many Nxters my Ardor account is the same address as my Nxt account, but you know, with ARDOR prefixing it and not NXT. It was a little odd seeing an account creation process from scratch.

One thing that I heard that bears repeating, nay, tattooing onto your forehead, is that THERE IS NO CUSTOMER SUPPORT for Ardor. If you lose your PRIVATE KEY you have lost access to your account. This is the 21st century people – take some responsibility!

An interesting note is how US-centric these videos are. As our American audience knows, about the only real way to access the crypto world is through Coinbase. Oh, the horrors, the PTSD-like flashback of my account registration process with them last year. Shivers descend down my spine. Yet I persevere, I am not afraid. A critique I have is how hand-wavey the “Obtaining Ardor” video is for those who are truly beginners. The course recommends buying Bitcoin and converting it to ARDR on third-party exchanges. It reminded me of those cooking shows you see on TV: the host just magically has a pre-made version of the recipe just below the counter while you are struggling and making a mess of your kitchen trying to mix all the ingredients together. The video abstracts away A LOT of the frustration many users will experience as they try and convert fiat currency to crypto. Alas, us Americans do not have access to MisterTango accounts so the convenience of AEUR is unavailable to us. Regardless, the videos do a decent job of explaining how to fund your account with ARDR.

Now I am watching how to declare your public key by completing my first transaction. I want to nitpick how he does not explain the difference between Ardor, the blockchain, and ARDR the token of the blockchain. I am a perfectionist and such things bug me to no end. But again, I am here to learn and not to complain.

Overall the first part was very informative and complete – it exposes the core important concepts of blockchain without going into unnecessary detail. Simple and easy to follow along and all-in-all a pleasant experience. Videos around an hour.

Wow, an hour of my time has passed. I felt like I deserved something and so do you for reading this far. I present you with fuzzy kittens!



Part 2: Advanced Placement

Part two of the course gets you down and dirty with the Ardor. For those only interested in trading crypto, Part 1 is enough. For those wishing to truly use and appreciate the future that is the blockchain, part two is for you. This is also where casual users of the Ardor platform can jump in and begin dabbling with the advanced functionality of the client.

Here I begin to explore the functionality of Ardor by using the Ardor testnet! Essentially I am using a real copy of the Ardor blockchain with FAKE tokens that have no real value. This way you can experiment without fear of losing tokens. From here on out the course takes place in the Ardor testnet in your browser and not in the Ardor client.

A shout out to Ardor.World – man this a great resource for anyone. In order to proceed in the course and become adroit at Ardor, I need to fund my testnet account. Luckily, you can get FREE testnet coins from the faucet links on the landing page!

It seems odd to me that FAKE testnet ARDR and IGNIS tokens are scarce – like why can I not have infinitely many fake ARDR tokens? I suspect that has something to do with how Ardor.world is set up. If I am wrong, please correct me in the comments.

Interesting to note that all the exercises for this section make use of the creator’s testnet accounts. There is no reason not to use your own, but I wanted to see if I could exactly use the same testnet accounts as Eric, the presenter, and I totally can. I feel like this does not scale with increased user activity, but hey, it works.

I finally get to experience conditional transactions. Not sure why they are called “Phased” transactions – I am ignorant of that distinction, I suspect it an esoteric computer science term. I created my first Approval Model and I saved it! Yet WTF am I limited to FIVE characters to naming things. Arbitrary limit is arbitrary, yo.

Random stock photo woman agrees with me

Continuing on now I am experiencing the Asset Exchange part of Ignis. I get it now, Ardor does not have an Asset Exchange. You and I cannot issue assets on Ardor but we can on Ignis because it is permissionless! That is sweet and totally makes sense now. This is coming from a guy who has written about this for a while now and yet it did not click until I actually created my own asset! The importance of asset control is mentioned many times here – the ability to control who can trade the asset.

Issuing assets and creating dividends is fun, it makes me feel like my own CEO. It is annoying how you need to search for assets by IDs so I hope you have handy the long string of numbers that represents the assets you wish to buy. A poorly optimized piece of UI for the Ardor client, but hey, it is what it is. Disclaimer, I understand that asset names are non-unique and that during the Ignis ICO there were many scammers out there selling assets named JLRDA. The only way to be sure you have the correct asset is by the asset ID. I just wish that there were a UI mechanism that would allow for verification of proper asset names such that I did not need to keep an ID string around.

I also get what Singleton assets are – nondivisible assets; like those absurdly popular crypto kitties on Ethereum.

Oh, for anyone who diligently does the exercises using the same testnet accounts you will need to copy and paste the passphrase like literally a million times.

Now for some real unknown waters for me: the Currency System. I have no idea how to create a currency, let alone do I know how they are different and distinct from assets. My understanding of Ardor continues to grow, as does my hair but that is not the point. The point is that I am deep in the course now, over two hours, and I am continuing to comprehend and appreciate the advanced features of Ardor.

Issuing my own currency is a little weird for me, but hey I can say that I have done it. The nuances of whether or not you want your issued currency to be “Reservable” and/or “Claimable” are subtle but powerful. Luckily the Ardor client (testnet and mainnet) are smart enough to not allow you to issue a currency with conditions that make it inoperable, but I sure wish that there was more documentation on what the significance of the categories are. I know the nxtwiki has documentation on this but it is not easy to grasp everything fully. It was fun to learn that, in essence, you can create “mineable” PoS coins and that you can enact conditions that only release the currency when they are fully met. There are many different currency types and different use cases for all of them. Admittedly this part was a little hard to follow.

The last few sections covered the many topics briefly. I created a poll whose only participants were the holders of my fake Ignis asset. Sweet – I see the usefulness of these polls. Why do I personally not use polls more often? Nxter needs polls – they drive engagement and are very easy to use. My only doubt is how can you link to them? This question is going to keep me up at night. But boy, are they useful!

The Data Cloud is cool, but documents are limited to 40K of space, good for hashes and code snippets. I understand that I can pay for more but man that seems small. Also, kudos to whoever listed Top Secret as a tag in the Data Cloud. I salute you, sir, or madam.

The Marketplace functionality of Ardor is great. I am guided through the Marketplace. The ability to list and sell things is great, but I wonder what guarantees I have of receiving the product? The same question exists on Craigslist and eBay but with them, the company can intervene on my behalf if a seller does not ship the product. On the testnet the products are fake – 5 IGNIS for a sailboat is too good to be true. LOL on whoever listed cocaine on the testnet Marketplace. The creativity and dark humor of people amuses me to no end.

Messages are the last section on my journey and it is mostly as advertised, but with an important distinction that I am probably the last person to appreciate: Shared Keys allow for third-parties to see encrypted messages to me without me giving up my Private Key/ Passphrase. That is a great point to understand and one that was here-to-before lost upon me – with them you can share sensitive data like identity documents, medical journals, certificates, whatever. Again, I am probably the last person to get this, but hey, better late than never!

And that is it, I put my headphones down. My 3.5-hour long journey is over. Before I was but a padawan, but now I am an advanced user! I am pumped and want to sell this exciting and exhilarating feeling of completing the course and gaining a much better understanding and intuition of the powerful functionality of Ardor.

I am no master of Ardor, but I am a sufficiently advanced user who now has the foundation to continue to explore and build my knowledge base. My journey is not over – it is only beginning.  It is a little deceptive to claim that anyone is a “Master” of Ardor after completing this course, but you definitely will be an advanced user.

The hands-on structure and constant manipulation of the Ardor testnet account were a great asset to me, and likely will be to anyone interested in exploring and mastering Ardor as well. A few minor gripes aside, (more on Forging and Bundlers please) and a complete lack of any mention to Lightweight Contracts, Multisig Transactions, and Cold Storage and proof-of account-ownership tokens, the course was engaging and methodical.

Nonetheless, believe that this course is very thorough and well-paced if not a little brief infrequently. The nuances of the many restrictions possible for currency and asset creation requires more of my time to fully appreciate all the different use cases for them.

Kudos to the creator for making this course. The material is accessible to all and well presented. The beauty of Udemy is that you do not need to watch every single video. You have access to all the content from the beginning and can immediately jump to the sections that interest you. Manipulating the exercises in Part 2 requires nothing from Part 1 if you already have the Ardor client installed and running.

The blockchain is the future people, experience it! Long series of sequentially hashed files are the future and now I am an advanced user of Ardor. I am prepared. My Private Key is secure, my high fives are for sale and I am ready to broadcast on Ardor, and to the world, that I am truly appreciative of the advanced blockchain features that are standard on Ardor.


I feel accomplished and I experienced, hands-on, much of the great functionality of Ardor. What are you afraid of when it comes to learning and personally exploring Ardor? Here, let me incline you to begin the same journey as me by offering this Nxter code course discount!

To many, a blockchain is a scary thing, an abstract concept that is hard to connect to. This is patently absurd – overcome your fear by practicing with it – it exists right now. Wonderful functionality already exists that is immediately usable for most anyone and this is just the beginning of what is to come!  There are many great features of Ardor: the Coin Exchange, the Monetary System, the Voting System, the ability to add conditions to transactions, Aliases, Currency creation, the Marketplace, all of it. But it is nothing more than words unless you experience it – dabble with it. Make it your own! With the release of this course, I believe that the time of being hesitant is over. Take the course and learn the advanced topics and concepts of Ardor. Now it is May and soon it will be June and then it will be summer and then you will be dead! Act now and learn the joys of using Ardor, you will be filled with regret of not taking a small amount of time to appreciate just how powerful a tool we have at our fingertips right now.


If you have been a follower of the biggest development in the cryptoland, Ardor, then you must have read the first episode of this article series. Well, if you haven’t read it or you haven’t been following, then I say congratulations to you for seeing this sequel. Verily, you have finally found the future; now it lies in your hands. In the first episode, we discussed some of the adorable features of Ardor. They are adorable for, with Ardor and all which it represents, Cryptocurrency becomes worthwhile and interesting. Now, we shall discuss another feature of Ardor, by discussing what it involves and basically how it works.

May 2017, Jelurida’s Co-founder and Senior Developer, Lior Yaffe, was in Spain where he presented a voting use case based on the Ardor Blockchain platform at a live broadcasted Blockchain event organized by El Pais Retina in Madrid. The demo was prepared and demonstrated in collaboration with Accenture Spain and it showed how easily our Blockchain and its voting feature can be adapted to this important real world use case.

Well, you may begin to wonder what voting has got to do with activities in the cryptoland. You are probably asking if Ardor has secured the contract to organize the next presidential elections. Fortunately, we are here for you, for everyone, and for every organization. Since we often make decisions from time to time, we have established the voting features for use by our members.

Using the Voting System, any account can create a poll with one question and up to 100 answers. The creator of the poll qualifies who can vote based on the account, the balance per voting account, an asset, or a currency. Here is a summary of how it works.

#Poll creation: This is the first step in the voting system. Here, the administrator will be eligible to create specific questions and add them in the blockchain.

#Registration/Notification: The registration will be received through a medium which shall be received by stakeholders or eligible candidates.

#Casting of Votes: While votes are being cast, counting of the votes is on, and this will be done by the Blockchain itself.

#Poll Validation: The votes are confirmed and validated.

#Poll Ends: Here, the voting is brought to an end, after which nobody will be eligible to vote.

#Poll Results: Results are instantly presented in graphics and other forms.

The voting system allows for an online database, unlike the manual voting based on paper. A consensus method is adopted in casting and the results are released instantly; so no more waiting or unnecessary delays. Also, votes can be cast from anywhere, whether browser or mobile application. The system is user-friendly and there are in-built fraud avoidance features, which make it immutable, traceable and reliable.

So do you get the idea? The Cryptoland has been hit by changes, and the only solid ground is that which is open to positive changes. Not anymore is it just about the coins or trading in them, but a whole lot more. We are glad that Jelurida, the umbrella under which these groundbreaking ideas surfaced is at the forefront of this evolution. This is just the beginning. The wonders of Utopia cannot be comprehended or experienced in few days in time or pages in tales.

Ardor, A tour through Utopia (I)

One of the previous publications on Ardor addressed a germane issue in the Crypto-land. This issue is that which is concerned with investment, patience and ultimately, the need to make massive profit after strategically adopting the former concerns. The publication was inspired by a conversation among Crypto actors on the expected return from their investments in Ardor. Fortunately, they were later convinced that Ardor is no scam or fraudulent scheme, but a platform that has come to stay and also a platform, where the future of blockchain lies.

But let’s put that aside. Have you realized that Ardor has some adorable features which makes cryptocurenncy worthwhile and interesting? No? Ooopppsssss, you are definitely missing out.

Yes! You might probably refer to it as E-commerce in a new dimension, but it is certain that this is one feature which you will definitely enjoy. Buying and selling has been made easy with Ardor and members of the blockchain can easily trade goods win one another. Easy, right? Definitely. Here, two things come to play -members buy from and sell to others on the blockchain; and enterprising members are empowered to market their products to others on the Ardor platform.

So, Ardor allows you to have a blockchain marketplace where anyone can buy and sell physical and digital items. The Marketplace is already a part of the Ignis child chain and any other child chain to be established under Ardor shall possess this great feature. This is cryptocurrency renewed, this is adorable, this is Ardor.

The Ardor platform describes this feature thus; “The Marketplace enables direct peer-to-peer trading on the blockchain. It is an open decentralized store for all digital goods. You may sell or purchase software, music, video, ebooks or any other kind of digital good here. Simply browse the available products, place an order and the seller will send you information of how to download the good (usually a link) inside the blockchain system.”

The platform acknowledges a development which shows progress and commitment, thus “although Marketplace was designed for buying and selling digital merchandise, physical items have also been listed for sale”.

It is well known that security is key to the success of any business -online and offline. In the case of online businesses, like operations in the crypto-land, it is always of great need and emphasis with the aim of protecting online actors, avoiding exploitation and manipulation of various kinds. Therefore, it is for this reason that Ardor and it’s child chains possess the Account Control feature, which is a security measure that ensures that access is rightfully restricted and unapproved transactions are prohibited.

The Ardor platform explains the features further. It states thus; “Restrict access to a blockchain account or prohibit transactions without approval by multiple parties. Rules can be written for each account to limit the terms of a transaction. Features of Account Control include setting a lock on an account to prohibit any outgoing transactions and defining a set of rules for unlocking the account”.

It should be noted that above are just two among the several features of Ardor. While other features shall be discussed in subsequent publications, it is already evident that with Ardor, activities in the Crypto-land is interesting, enjoyable and adorable. If you want to journey to a far land, yet so near; with beauty beyond which words can describe; and have an interesting voyage same as the rest but with a different experience, then take a journey to Ardor. The Utopia of Crypto-land. The chains have gathered, the train is moving and the destination is nowhere but the future of blockchain.

The Equal Market You Ought to Explore

Equality has always been a farfetched term and only exists in the dreams. Unfairness and inequality have gone beyond the five fingers and have eaten deep into all systems. But then, this isn’t a conversation that concerns us at the moment. However, the market is. Who can survive without a market? No living man can, unless he provides everything he needs all by himself. The greatest of all markets of course is the financial market, as money is another commodity one can’t do without and a conversation everyone wants to engage in. After all, it makes the world go round. So, let’s talk about “The Market”, “The Money Market”.

Let me throw out a rhetorical question to my dear readers. “Have you ever been to a market place?” The obvious answer is that nearly everyone has – whether from the corner of our rooms through the internet windows on our mobile phones, or actually through physical interactions. It’s a place for all commodities essential to human life. Several years back before the introduction of the Financial Market system, it will be deemed a myth to forecast a future of such market. Today we have Foreign Exchange Markets and, even more, we have the Exchange for Digital currencies. Now, that’s a market everyone is talking about. A future some few are afraid of.

The idea of having a decentralized, difficult to corrupt system and a future of independent financial structure terrifies me. I am the man behind the corrupt politics, a wealthy aristocrat who wants it all for himself.  But then, the world we know has become little and encircled by the Crypto-space. Cryptocurrency is here to stay. Cheers to the common man as he at last has a fair and equal opportunity in the space.

Available materials show that Cryptocurrency came in as a side product of another invention. Satoshi Nakamoto, the unknown inventor of Bitcoin, the first Cryptocurrency, never intended to invent a currency. In his announcement in late 2008, he declared that he had developed a ‘Peer-to-Peer Electronic Cash System”. Satoshi’s invention was a successful creation of a decentralized digital cash system, which came in after several attempts had failed. Well, that was about ten years ago when Satoshi made his invention, which is still raising questions, fear, as well as optimism among the populace.

Years have passed and the rains of ideas have fallen unto the plains of execution effecting sudden germinations of several digital currencies. They rose from all directions with similar offer but only a different name and people behind it to distinguish them. Few stood out with more to offer and determination to bring that future even nearer. From BCNext came the idea of such a rare currency in 2013. A second generation of cryptos that was developed from scratch. It came with it many features that would have been thought of to be the future of digital currency such as shuffling, decentralized DNS, peer-to-peer exchange, voting system to mention a few. It emphasized on the broad nature of blockchain which was more than just a currency.

As a continued effort of the 5-year Legacy of NXT came Ardor in the earliest hours of 2018. A second iteration of NXT, a whole new exciting journey of cryptocurrency with new and interesting features. Sitting on the throne as the first parent chain, Ardor welcomed the first child chain, “Ignis”, each with individual differences and goals in the blockchain vision realization. To the team behind it, the future is all that matters. A future with a carefully laid foundation is definitely a never-ending one. Part of the features that makes the whole development more than just a currency to be traded is the Market Place. The end dream of every currency is to be spent and not just traded of. Paving the path to the future where cryptocurrency realizes its goal of being a genuine means of exchange makes it a cryptocurrency of the future.

As the Ardor Platform puts it: “The Marketplace enables direct peer-to-peer trading on the blockchain. It is an open decentralized store for all digital goods. You may sell or purchase software, music, video, ebooks or any other kind of digital good here. Simply browse the available products, place an order and the seller will send you information of how to download the good (usually a link) inside the blockchain system. Although Marketplace was designed for buying and selling digital merchandise, physical items have also been listed for sale.”

So, when the idea crossed your mind of being part of the great future in the emerging blockchain industry, think no further. It can’t get any better than the one that builds on the two greatest entities, Market and Money. This is the big thing. It is a market for you, me and every one of us. It is a market you ought to explore.

IGNIS Airdrop

The holiday season is upon us and soon free IGNIS tokens will rain down into your Nxt accounts! 500M IGNIS tokens will be airdropped on NXT coin holders at the New Year!

What is Going On?

On Dec 28, 2017: a snapshot of the Nxt blockchain will occur:

Jelurida takes a snapshot of all NXT accounts with everything in them, including the NXT you hold, your registered aliases, account properties, your NxtAE (asset exchange) portfolio, Marketplace items, Monetary System coins, etc. The state of the blockchain. Your NXT balance @ the snapshot block determines how much IGNIS you will get: 1 IGNIS per 2 NXT.

With the snapshot block, some coins and trading markets will be temporarily frozen.

These tokens will, temporarily, become untradeable: ARDR (the Nxt asset which represents ARDR tokens on the Ardor blockchain platform), JLRDA (which represents the IGNIS tokens sold during the ICO), Janus (which will be re-issued on IGNIS/Ardor), and also BITSWIFT, which will be reborn as an Ardor child chain, along with Ignis, with the Ardor Genesis block.

The Ardor platform and its first child chains will launch on 1/1-2018 0:00 ETC.

From that moment, when the Genesis Block is forged, the markets for the beforementioned tokens are open again. For every 1 NXT you have in your Nxt account on Dec 28, at the time of the snapshot, you will find an additional 0.5 IGNIS, on the Ardor blockchain. You can already log in to the Ardor testnet with you current Nxt account ID and see how it works. Also, 10% of the BITSWIFT child chain tokens will be distributed to IGNIS holders. Not because of the JPL license, but because Bitswift has decided to reward the Nxt and Ignis community, with an extra Xmas gift to holders!


IGNIS is the transactional token of the unrestricted open to all blockchain 2.0 Ignis child chain, spawned from Ardor, the scalable disruptive platform that Jean-Luc, Nxt lead developer since 2013, and Jelurida, have created.

Those that listened know that the Nxt platform will not become obsolete but will be taken care of, as a perfect showcase for Jelurida and a still relevant featureful public blockchain, under the JPL license. The JPL (Jelurida Public License) aims to protect investors in the NXT token, while at the same time keeping the core code open source. According to the JPL, any clone of Nxt must distribute 10% of the newly issued tokens among NXT holders, proportionally according to their stake in NXT.

Jean-Luc explained:

[With JPL], unlike the GPL, in addition to the copyright owner (Jelurida) any token holder can initiate a claim, because he has incurred a loss. It will also be much more straightforward to demonstrate the total monetary value of such losses, as 10% of the marketcap of the infringing clone.

IGNIS inherits all the features of NXT. Plus more. Much more.

Ignis is spawned from Ardor. The Ardor server software can run on a mobile phone, a Raspberry Pi or a VPS, and anyone with ARDR can earn fees from forging ChildBlocks (blocks of bundled transactions made on Ignis and other Ardor child chains). Forging is Nxt and Ardor PoS’s equivalent to PoW “mining” and secures the full Ardor network.

Other ways to support and monetize the network is (currently) Bundling or running Archival Nodes.

Child chain transactions are not forged on the child chain but are bundled and sent in blocks to the Ardor parent chain, which forges, files, and secures them. Anyone can become a Bundler, and bundle child chain transactions. It takes ARDR to be a Bundler, because the Bundler must transfer ChildBlocks (those consisting of bundled child chain transactions) to the Ardor parent chain. Ardor only accepts ARDR. Bundlers are paid in child chain tokens for their service. They set their own fee.

Archival Nodes expand the default network when it comes to storing data on the blockchain. Messages sent between accounts as well as other kinds of encrypted or public data uploaded to the network are “pruned” from child chains. Only hashes are stored, which makes the child chains scalable – unnecessary bloat is removed at regular intervals. Archival Nodes, on the other hand, store pieces of data, so they can be dug up and used. Thus, Archival Nodes provide a distributed data storage network to Ardor’s blockchain ecosystem – which, of course, also can be monetized. This is already built into the platform. The first archival node service provider will be Jelurida, but competition is welcomed.

Smart Blockchain

IGNIS lives on and communicates with this full network. It’s part of a scalable platform; Ardor, the advanced EXISTING BaaS platform, which allows transactions to be sent across the full network of child chains, globally. For example, an asset that is issued on Ignis will become instantly tradeable on all child chains that support the AE. Be they business token child chains or simple gateway child chains with tokens pegged to other cryptocurrencies or a bank/government-backed fiat coin, like DKK, EUR, USD, YAN, which you can deposit/withdraw directly to your bank account. On top of this, Asset tokens can be issued with their own unique rules set and specified- like, if they can be traded by all, or only by selected accounts, pre-approved by the issuer of the asset, or tagged in the blockchain as KYC/AML/CTF compliant accounts. Also, Ignis currency tokens (MS-coins) can be traded between child chains. Whatever you do, you can scale it. Whatever you do, it is in your control, finally.

I think that the Nxter Magazine should soon begin talking about use cases. Or about building commercial applications on the public blockchain. Maybe we could even run a contest! Describe a use case that solves a problem for you, and win!

It could be a lot of fun. Those that win the contest by vote, could get an advisory board, some initial funding, marketing and possibly a partnership arrangement with core Nxters. Nxt, IGNIS, and Ardor are supposed to solve real problems, you know, and the tech is capable of it. As IGNIS and ARDR appreciate in value, and with our sponsorship with Jelurida we *could* make this happen. Follow, learn about Nxt and Ardor, sign up for the news. Maybe we will make such a contest. Until then, feel free to post ideas for use cases in the comment field. Here’s why:

Use Cases

One of the most important aspects of Ignis is what it offers to the developer; e.g. businesses, local societies and even to national governments. All the advanced basics of connecting your use case to the blockchain are covered. Tested, reviewed and approved in the wild, Ignis (and the NXT and Ardor platforms) offers working executable secure inbuilt smart contracts, that developers can combine into the use cases he/she/the customer wants, as easy as with Lego bricks, with the API.

Right off the bat, Ardor is a well-prepared infrastructure of an entire economic system, with all its twists and turns, an infrastructure built on the blockchain, which is ready to go global on January 1st.

New GUI’s, apps and Dapps (decentralized apps) are expected to emerge:


The child chain infrastructure seemed to solve all of the problems we were looking at, blockchain bloat, reducing fees, fast confirmations, everything we want it comes with to start building on.

Our rewards network is built on top of this blockchain technology which ensures stability, reliability and transparency, while maintaining exceptional performance.  

Dan Charbonneau, CEO of CBT Nuggets:

[Our] learners will buy training content with crypto and consume the content. We’re developing a cryptocurrency to be deployed as an ARDR child chain that will provide a financial incentive to learning. There are quizzes throughout the content so you can prove you learned the material. When you answer the quizzes correctly, 30% of your purchase price is returned to you. In addition, everything you learn is stored in the blockchain so we will maintain a lifelong record of learning for you.

When you interview for a job, you’ll be able to show the interviewer everything you’ve learned. The transcript will of course be private only for you and shared with the people you choose. The value of our cryptocurrency will be pegged to ARDR on a 1-to-1 basis. The initial launch will be with 50M of the new cryptocurrency paid for with 50M ARDR. The currency will be redeemable on a 1-to-1 basis for ARDR so it has value out of the gate.

I’m hoping this changes education worldwide, providing greater access to quality content and adding competition and the principles of the free market economy to education at all levels.

Alex Pfeiffer, University of Danube – Center for Applied Game Studies:

As we talk on a daily basis with Jelurida (…) at the moment I am 100% sure about doing the following “proof of concepts”. I can speak about my plans but I don’t like to reveal any partners before the ink is dry ;).

Doing my research for several months I switched all my developing plans first from Ethereum to Ethereum Classic and finally decided to fully go on Nxt and later Ardor for my plans regarding setting up new ecosystems.

I also decided to work with Ardor and Nxt for a very simple personal reason. I am economist, social scientist, game designer and conceptional developer. I am not! a “real” technican. Working with Ardor gives me the chance to understand most of the stuff the tech people are doing with it and it enables me to chance things and not crashing the system.


Adel is built on the Nxt platform which has numerous features that will be extended to the Adel ecosystem. [Adel] will move to the Ardor platform, once it is deemed suitable. With this foundation of advanced blockchain features, the Adel ecosystem can focus on project development, best-in-class business practices, and an efficient and self-sustaining community. Adel will continue to capitalize on the features of Nxt and Ardor as both evolve.

So, What Is Next?

The “Bitcoin-thing: transferring money, is one use case of the blockchain; but Ignis and Ardor bring ALL the Blockchain 2.0 ideas to life. Ideas like running secure proven smart contracts on a scalable decentralized blockchain infrastructure, not with the old energy-wasting PoW algorithm but an energy efficient and green 100% PoS algorithm.

You can build decentralized applications with little coding experience on Ignis. Run your own business on Ignis, even create a DAO. Or with Ardor you can get your own child chain, it’s scalable, connected to the network. The impact and transformative nature of the changes to businesses and governments that the Ardor / Nxt / Ignis blockchains bring are unimaginable.

To old Nxters, this is not news. But it must be said: on January 1st, 2018, Ignis, Bitswift and Ardor will launch. Almost everything envisioned by the great, early Bitcoin (and Ethereum) blockchain visionaries will be doable and live with Ignis and Ardor. One can only hope that the launch on Jan 1st will spark a disruptive network effect. And oh yes, you can be part of it! Begin by sharing this article.

Learn about the utilities of Nxt and Ardor, and apply it to your own life and see which problems you can solve with it. Share it with us.


We have all seen the price of NXT and ARDR increase. I see it talked about a lot in forums, slacks, and on social media, and I spend a lot of time giving answers to folks who want to know if they will get IGNIS, ARDR and BITSWIFT if they hold their NXT on either this or that centralized exchange. Short answer: Why would you?

I have used NXT for a long time. Now Ignis and Ardor are coming. I know, for a fact, that in a not so distant future I will never have to use a centralized exchange ever again. If YOU don’t know that, you don’t know what you’re investing in. You invest in disruptive tech. Not like Jelurida is against the established system, with its taxes and governments, they will work with them all. Yet, their tech is public. Anyone can use it out of the box or build applications on top of it, change things.

Maybe NXT and ARDR exchanges like Bittrex will support the snapshot. Maybe Poloniex will, and AEX, Bitcoin Indonesia, HitBTC, Litebit, all of them – and maybe they won’t! None of these exchanges have made an official announcement about the IGNIS airdrop yet, the date is closing in, but what they all want is to get paid. By Jelurida.

UPDATE: These exchanges have announced support of the airdrop

So you ask me: Will the airdrop be supported by this or that exchange?

No one knows yet. IMHO, centralized exchanges act like they are banks, nowadays. They will list IGNIS, as well as NXT and ARDR, of course, they will, they earn millions in trading fees, but that’s not enough. Profit maximizing middlemen, some of them are, and they do not even provide an indispensable service. We do not really need them. Nxt and Ardor have inbuilt unhackable decentralized exchanges. So, to make sure you get your IGNIS and Bitswift tokens for holding NXT, and your Ardor tokens for holding ARDR, I strongly recommend you to simply claim your own private account on the network.

Create it offline, with a web client, or locally, by downloading and running the NRS client from Jelurida. The web client is the fastest and easiest, requiring only a minute or two of simple setup. Be sure to keep your passphrase safe!

Personally, I care about supporting blockchain technologies that I know will accomplish great things. I do not buy and trade shitcoins. And I do not know how many day traders, dolphins, whales, and bots manipulate the price of each coin, including NXT. That’s not my thing.

Buying cryptocurrencies seem like a (risky) get-rich scheme to a lot of people today. Even “average Joes” seem to think they know the market and that it’s probably a good time to enter. But a lot get burned. There’s no cancellation of transactions. Do your due diligence. Make your own decisions. And never invest more than you can afford to lose.




Ardor vs. the Competition, Pt. 6: Komodo/SuperNET

This post is part of a series that compares Ardor to other blockchain projects with similar features or goals. You can find the previous posts here:

This week I studied Komodo, the blockchain platform that forms the basis of SuperNET.


Like Waves, SuperNET was founded by someone who was quite active in the Nxt community in the past. And as with my article about Waves, I won’t attempt to rehash that history here.

Suffice it to say that James/jl777 was the developer behind SuperNET, the Multigateway, and several other projects on Nxt, including a number of assets on the Nxt Asset Exchange, but he left the Nxt community during the turbulent period of late 2015 and early 2016. Since then, he has created the Komodo platform, which now serves as the foundation of SuperNET.

The vision of SuperNET is to enable users to seamlessly transact with many different cryptocurrencies in order to enjoy the unique advantages of each coin. The experience is to be so seamless, in fact, that the user might not even realize that he or she is using multiple coins. For example, if I understand correctly, a SuperNET application might allow users to transact privately with Bitcoin by converting to and from a privacy coin like Komodo behind the scenes. From a user’s perspective, it would be as if Bitcoin had “borrowed” Komodo’s privacy feature.

SuperNET isn’t itself a blockchain. Rather, it is a framework comprising several parts. The main ones are:

  1. Komodo, a blockchain anchored to Bitcoin;
  2. assetchains and geckochains, independent blockchains anchored to Komodo;
  3. the Agama wallet, a multicoin wallet;
  4. BarterDEX, a decentralized exchange (DEX) that will be integrated into the Agama wallet; and,
  5. Iguana, the codebase that underlies the Agama wallet and part of Komodo.

Note that much of the literature about SuperNET refers to the Agama wallet as the “Iguana wallet,” which was its previous name.

The “anchoring” process in items 1 and 2 is Komodo’s delayed proof-of-work consensus algorithm, which I describe next. I’ll return to BarterDEX later.

Delayed Proof of Work

Komodo is a fork of zCash, which is a blockchain that uses zero-knowledge proofs (via zk-SNARKs) to allow users to transact without publicly revealing their account numbers or the amounts that they exchange. Komodo has added several features to its branch of the zCash codebase, including the delayed proof-of-work (dPoW) consensus algorithm and a mechanism for creating additional blockchains that are periodically anchored to the Komodo chain.

The dPoW white paper argues that the dPoW mechanism allows any blockchain to secure itself using Bitcoin’s hashpower by periodically notarizing itself to Bitcoin. In a nutshell, consensus on the weaker blockchain occurs in two stages: an initial consensus by normal means (e.g., PoW or PoS), and a second layer of consensus established periodically by a set of notary nodes, elected by stakeholders, that record a hash of the weaker chain’s most recent block on the Bitcoin blockchain. All nodes on the network agree that, in the event of a fork, they will not reorganize the blockchain past the last time it was notarized on Bitcoin.

In this way, the author argues, the weaker blockchain inherits some of the security of Bitcoin. Even an attacker with a large majority of the network’s hashpower won’t be able to modify the blockchain back past the most recently notarized block. Accordingly, somebody who waits for a transaction on the weaker chain to be notarized on Bitcoin can be confident that it won’t be reversed.

The white paper also proposes a mechanism to allow the network to fall back to the initial consensus mechanism in the event that the notary nodes become unavailable. The idea is that all nodes on the network are eligible to mine, but the notary nodes are assigned a lower difficulty level than normal nodes. As a result, notary nodes will normally win most or all blocks, but if an attacker were to somehow take them offline–by a DDoS attack, for example–normal nodes would be able to continue mining blocks and the blockchain would continue uninterrupted, except without the added security of Bitcoin. In this way, the dPoW chain is somewhat less centralized than it appears at first blush.

This line of reasoning does beg the question of exactly what is gained by the notarization mechanism, though. In particular, if an attacker can gain control of the notary nodes, he can prevent them from signing the Bitcoin transactions that notarize the weaker chain’s blocks, forcing the weaker blockchain to rely only on its initial consensus. So it appears that the extra security provided by the notarization process depends implicitly on an honest majority of notary nodes.

[EDIT: After talking with jl777, I learned that Komodo allows a minority of notaries, 13 out of 64, to sign each notarizing transaction. This simultaneously reduces the Bitcoin fees that must be paid and makes the proposed attack harder, since an attacker would have to control a supermajority of notaries to defeat the notarization mechanism. My original statements were based off of what he wrote in the dPoW white paper, which suggests that 33 of the 64 notaries must sign the notarizing transactions.]

This is basically the security model of delegated proof-of-stake (DPOS) blockchains like BitShares. In both dPoW and DPOS, users vote by stake for a set of “special” accounts that the rest of the network depends upon for its security. Both systems suffer the same weaknesses, too: a burden on users to keep up with the “politics” of the system to know which accounts are trustworthy enough to vote for, and the corresponding voter apathy that this burden produces.

All things considered, I’m not sure I see a strong case for dPoW over and above other alternatives. If the weaker chain’s initial consensus mechanism is strong enough to secure it, given its current economic value, then paying Bitcoin fees to notarize it seems like a waste of money. If the initial consensus is not sufficient, on the other hand, then it seems that the security of the chain rests entirely on the election of honest notaries. But in that case, why not use DPOS and take advantage of the increased transaction throughput that DPOS chains have achieved?

Setting these considerations aside, though, it is worth noting that the Komodo platform uses nested dPoW chains to help achieve SuperNET’s vision of interconnecting a variety of different blockchains. Komodo’s additional chains are called “assetchains” and “geckochains”. These chains notarize themselves to Komodo, which in turn notarizes itself to Bitcoin. Again, the claim is that all chains involved inherit the level of security of Bitcoin, but as described above, a lot depends on each chain’s notary nodes.

Unlike assets on Nxt and Ardor, or even child chains on Ardor, Komodo’s assetchains are fully independent blockchains. Their only connection to the Komodo chain is the dPoW notarization mechanism. In this way, they are perhaps closer to the sidechains that Lisk and Stratis envision than they are to Ardor’s tightly-coupled child chains.

Geckochains are like assetchains but with support for smart contracts. I haven’t found many details about geckochains, and they don’t appear to be available yet, but the Komodo client does currently support assetchains via a command-line interface.


SuperNET’s decentralized exchange, called BarterDEX, allows users to atomically trade coins across supported blockchains in a trustless way. The team has not yet integrated it into the Agama wallet’s user interface, but they’re working on it now, and in the meantime BarterDEX can be used on its own.

BarterDEX consists of three main components: a designated set of nodes for matching orders; a set of “liquidity provider” nodes to act as market makers; and a protocol for users to exchange coins from two different blockchains with each other as a single, atomic operation.

The order-matching nodes serve the same role as they do in Waves: they partially centralize the task of matching buy and sell orders in order to provide a more responsive user experience. This way, traders don’t have to wait for the next blocks on the blockchains in question to know whether their orders have been filled or to cancel an order.

Liquidity provider (LP) nodes maintain balances of at least two supported coins and automatically trade them at a user-defined profit margin relative to a centralized exchange. For example, it is possible to set up an LP node that trades BTC and KMD on BarterDEX and also on Bittrex. Operators of LP nodes assume the risk associated with holding funds on a centralized exchange, and in return they profit from arbitrage opportunities between the two markets. Other BarterDEX users, for their part, get more liquidity and tighter bid-ask spreads than they would see otherwise, without having to store their coins on centralized exchanges.

After a user’s order is matched, likely to an order submitted by an LP node, BarterDEX uses an atomic cross-chain swap protocol to settle the trade on the two blockchains involved. Presumably the details vary somewhat depending on the trading pair, but conceptually the process is similar in each case. One blockchain is assumed to be compatible with Bitcoin, or at least to support the equivalent of Bitcoin’s hashed timelocked contracts (HTLCs). The other blockchain must support 2-of-2 multisig transactions.

Suppose Bob is trading his funds on the Bitcoin-compatible chain for Alice’s coins on the other chain. Alice and Bob each create a public key/private key pair and exchange public keys and hashes of the private keys. Alice sends Bob a 2-of-2 multisig transaction that he can spend once he knows both private keys, and Bob sends Alice a hashed timelocked transaction that Alice can spend by revealing her private key. Once she does, Bob uses it to unlock her multisig transaction and the trade is complete.

The protocol adds a bit of complexity to protect each party in the case that the other exits the process early. If Alice walks away without spending the transaction that Bob sent, Bob can recover his funds after the timelock on that transaction expires by using his own private key. Conversely, in order to protect Alice from the same risk, the protocol requires Bob to submit an initial “deposit” in the form of a hashed timelocked transaction. If he walks away before paying Alice, she can wait for the timelock on this deposit to expire and claim it for herself.

This is admittedly only a high-level overview of the atomic swap protocol, but hopefully it gives you an idea of how it works. The most important part is that there is no centralized exchange to facilitate the trade: Alice and Bob have exchanged coins on different blockchains without having to trust each other or some intermediary. You can find more details in the BarterDEX white paper.

Compared to Ardor

What do we make of Komodo and SuperNET, then? This question largely hinges on whether Komodo’s delayed proof-of-work algorithm offers a substantial degree of additional security to Komodo and its assetchains. In my view, it does not: it offers roughly the same degree of security as the delegated proof-of-stake algorithm, even if the notary blockchain is assumed to be perfectly immutable.

In this light, Komodo’s assetchains look a lot like the user-deployable sidechains that Lisk and Stratis aim to offer. In all three projects, and in contrast to Ardor’s child chains, each assetchain or sidechain is responsible for its own security. Komodo seems to have a head start on both Lisk and Stratis in terms of functionality, though, as users can already deploy their own assetchains and conduct atomic swaps on some pairs.

Note that Ardor’s child chains store hashes of their blocks on the Ardor chain, rather like Komodo stores hashes of its blocks on Bitcoin, but there is a crucial difference: Ardor’s forging nodes validate all child chain transactions. Each child chain effectively inherits all of the forging power of the Ardor chain, rendering it just as secure as Ardor and obviating the need for separate miners or forgers.

With regard to cross-chain atomic swaps, Ardor and Komodo are perhaps a bit more comparable. Ardor natively supports transactions among child chains and also between each child chain and the parent chain. Moreover, it supports a phased transaction type that is equivalent to 2-of-2 multisig, enabling the same kinds of atomic swaps with Bitcoin-compatible blockchains that BarterDEX uses. Ardor even adds the ability to combine multiple phasing conditions with Boolean AND, OR, and NOT operators, potentially allowing users to create the equivalent of a hashed timelocked transaction. Using BarterDEX’s approach, this feature could enable atomic cross-chain swaps to any blockchain that supports 2-of-2 multisig.


SuperNET’s vision of independent but interconnected blockchains is quite compelling, and between the Komodo platform, the Agama wallet, and the BarterDEX exchange, SuperNET has made real progress towards realizing that vision. While I am skeptical that the delayed proof-of-work algorithm provides substantial additional security to Komodo and its assetchains, the ability to quickly deploy an assetchain at least puts Komodo ahead of Lisk and Stratis in the race to build a functioning sidechain platform. Also, I see a lot of value in the ability to easily conduct cross-chain atomic swaps using BarterDEX.

Even so, I have to wonder whether there exists at the heart of SuperNET a fundamental tension between two of its goals. On the one hand, it aims to integrate the best features of many disparate blockchains, providing users and developers a seamless way to enjoy the unique advantages that each chain offers. On the other hand, it has offered Komodo as a single platform to solve most problems, supporting as it does private transactions, user-provisioned sidechains, and, in the future, smart contracts. Success at either of these goals seems to undermine efforts to achieve the other.

Ardor, for its part, also has a compelling vision, and one that is perhaps a bit more coherent: to support a multitude of businesses and projects on its child chains, making available to each a set of prepackaged features, allowing each to interact with the others, and requiring none to provide for its own security or to store forever the histories of the others. Ardor already offers most of the technology required to realize this vision; what remains is for businesses, developers, and users to put that technology to good use.
