May Report #2: The Silence Before The Storm

May Report #2: The Silence Before The Storm

Development Update

Since a few weeks we are waiting for the new version. Just now, a small hint arrived that this may soon™ be over:

I’ll give you a short list of what we can expect and as an addition, a small summary of the biggest things you might have missed. The May Report 2.

The most important piece first: In a few days, IOTA will show its capabilities.


Right now, a day after Doms small update (above), the Coordinator is online again, but not attached to the Tangle.
That means:

  • An update of the new IRI is imminent.
  • As Dom pointed out: There will be no snapshot, for now.
  • We can expect big announcements in the following days (Maybe also when and where IOTA will be listed).
  • The wait is finally over!
  • With the new version, the spammers can be used for the main net again.
  • Countless new full nodes will be set up, mine including (Let’s meet in #nodesharing when the new IRI/GUI is here).
  • After the update the Tangle and the confirmation timings will be faster than ever.
  • YDX can withdraw all iota.
  • We’re getting closer to the “liberation of the Tangle”, when the Coordinator will be shut down in July. Then, the Monte Carlo Random Walk algorithm will be activated instead.
    That way, the tip-selection and protection of the network will be ensured, while the scalability can unfold perfectly.

Take a look in our slack in the next days to catch the next instructions and announcements. That way, we can build the Tangle topology, again, -in no time.

If you are a developer, please take a minute of your time and look at the ecosystem fund, if you want to work with and for IOTA:

Consensus 2017

Cryptocurrencies, in general have come very far.
Consensus 2017 was held nowhere else than on the New York Broadway. Hundreds of participants, CEO’s, thousands of enthusiasts were there, to share their knowledge and to show the world that Blockchains (and the Tangle) are here to stay.

As a part of Dominik Schieners US-journey, He also participated in the “IoT & Blochchain: Powering the Connected Device Economy“-Panel on Monday 22th.



David Sønstebø wanted to participate, but due to an unforeseen accident he stayed in Norway and sent Dominik Schiener instead.

Dom did a great job in describing his vision to the plenum, while the content of the discussion were not actually focused on a comparison of IOTA to Blockchains.

Instead, the discussion were hold on a meta-level and the experts shared their thoughts and insights about the chances of collaborations of banks and Blockchains, their personal vision and the problems and chances they may face in the future.

Also part of Consensus 2017 was Dr. Carsten Stöcker who took part in a panel discussion about “Energy Markets“.

Carsten, as always, did a great job in explaining his vision and afterwards, he also found a moment of his time to explain why he didn’t get into IOTA’s details. -For a good reason.

He furthermore announced that IOTA is on the testing roadmap for “Share&Charge” where IOTA is used to tag IoT devices.




David added: “We’ll unveil more info on the ‘Digital Twin project’ together next week, so stay tuned for that”

Exciting times!


The next announcement is a “medium heavy” sensation.

The “Decentralized Identity Foundation” formed around IOTA and Microsoft, Bigchain DB, Blockstack, Accenture and a lot more known companies.

The DIF is aiming for progress in the field of identification.

The different workgroups concentrate on the following fields:


More info on the workgroups you can find here:

For now, it’s unclear how and where these researches take place and what will be achieved, but considering the big list of known companies on the list, we can expect some interesting projects and fruitful results.


If you need a good comprehensive blog-post by Dominik Schiener, with an up-to-date overview of IOTA, I recommend this:

Wilfried Pimenta, IOTA Foundation member was also diligent in presenting IOTA:


With the keynote: “Introduction to the IOTA Foundation and the Tangle, the next generation distributed ledger / blockchain for the Internet of Things

Upcoming presentations

Mentionable Articles


  • [German] Der Altcoinspekulant ist zurück! Ich werde ab und an als Gastautor mitwirken und freue mich, dass der Altcoinspekulant von Lukas Fiedler und einer Reihe an Experten fortgeführt wird.

These are the most important updates for now.

This week will presumably open a lot of doors, so stay tuned!

Have a nice week,


May Report #1

May Report #1

Since we’re on a long dry spell for a few weeks now, it’s good to hear that there is still movement if we take a closer look.

The problems of the network, that has suffered quite a bit, are caused by the reduced amount of spammers in the main network.

As mentioned again and again: the devs are stress testing the new version, so they need all available hash power to ensure its functionality and security.

That’s the right way!

That being said, if people want to support the Tangle in its current situation: set up your own full node, with fresh neighbors and spam the Tangle, even if it’s just for a few days. 

As an addition: Yassin, the private escrow from has problems to withdraw iotas because the majority of transactions won’t confirm. And the list gets longer!

There is no fraudulent or malicious intent involved. With the new version, we all get the funds laying on YDX.

When this new version is ready to be used, we will also see a new era of speed, reliability, scalability and opportunities.

Blockchains will have a very hard time when the majority of developers, companies, and investors realize the true potential of IOTA.

That moment will occur, when the stress-test results are published, IOTA hits exchanges and the people feel the speed of IOTA firsthand.

A moment everyone is looking forward to.

In the meantime, have a look at the newest changes, additions, and developments in the IOTA ecosystem.


Growing Community

The main Slack of IOTA, the room for development, interesting conversations, the soil of good ideas has grown to a huge number of 3000 people already.

Last week, @Eragmus uploaded a little plot with an exponential curve of all members over time.

This trend is continuing upwards as lots of people are looking for an entry into “Yassin Dex”, but we also have a good amount of people, that followed the call of the ecosystem fund.

Either way, this is a splendid sign of what IOTA has become: A fast growing community that is interested in the disruptive capabilities of this distributed ledger technology.

New Developers

A few striking additions have been announced.
These guys were already working with IOTA for a while, but the time has come to give them credit and to show who’s working behind the scenes.

On the official blog are nice introductions of Paul HandySabri GoldbergAlfred Keller, Alon Elmaliah

Great people with enthusiastic, likable attitude, capabilities and of course a big impact on the whole project.

Kick-ass additions!


The IOTA Foundation is built of experts in their special fields, therefore it’s no surprise that they do what they do: they present their ideas and possibilities in conjunction with IOTA.

Dr. Navin Ramachandran, practicing Radiologist and well-known researcher from London, presented IOTA on TechUk on 8th May.

Thanks for your efforts!

Right now, Co-Founder Dominik Schiener is visiting a few important companies at the US-west coast (no info about who, when, what) , and after that, he is going to present IOTA at Consensus 2017 in New York, a great opportunity in the world of Blockchains, Fintech to show the world what’s coming after Blockchains.

Founder David Sønstebø’s plans to speak at Consensus 2017 changed due to an unforeseen accident, where David suffered an injury at his zygomatic bone.

Let’s hope for a speedy recovery!

Next on the agenda are the Accenture Open Talks on May 30th, where IOTA presents its technology.

We have to keep in mind, that these are personal efforts, and not a matter of course that they put in their free time and energy to represent IOTA again and again.

Sure, that sounds like I was praising them like some saints, but to be honest: which project you know, has founders and devs that work relentlessly to spread the word, to build an ecosystem and community?

If there is one, I’m pretty sure it’s there for a way longer time, and it’s already listed, like Ethereum or Bitcoin.

These efforts here all happen before a listing, in very serious realms, hence my enthusiasm that IOTA is a spectacular project that has to be reckoned with!


Here is just a small selection of the newest articles about IOTA.

Since the respective authors took their time, I suggest, you read them on your own:

IOTA Tangle Takes the Blocks Out of Peer-to-Peer, Distributed Ledger Networks


The overwhelming Bull market

Since the Blockchain technology as a whole gains attention everywhere, billions of Dollars are flooding into these new markets.

The recent astonishing bull market reached a total capitalization of almost $70 billion.

Most of these listed technologies are functioning on a Blockchain, so they all share the same problem: scalability.

The recent adoption, therefore, is both: good and bad because once the mass markets try to use Blockchains, they rise in value but also suffer

the consequences that we know as slow transactions, higher transaction fees and as an end result, a technical barrier to progress.

The Tangle, as we know, is scaling better, the more people use it. -Without fees.

So my personal opinion is that, with the rising adoption, there is no better investment as IOTA.

As of today, IOTAs cap is around ~$200 million. The listing alone will show how much it can rise and believe me, it will, just because the technical

circumstances of IOTA in this “blockchain-era” are absolutely outstanding.

I said it when the market cap was at $20 million (x10 since then), and I’m still going to stick to that when we hit $2 billion market cap:

There is no limit!

The next weeks will be vital and hopefully filled with great milestones. Well, we do not know otherwise.

Stay tuned and have a nice week,


The IOTA Ecosystem Fund: 2000000 $ for Development and Adoption

The IOTA Ecosystem Fund: 2000000 $ for Development and Adoption

Once again, the IOTA grassroots movement made a difference in showing the world that this is no ephemeral cryptocurrency but a serious endeavor that leads to a technology, that possibly changes everything.

The generous sponsors of the ecosystem-fund are part of the “Ecosystem-club”, initiated by Luey Forje, one of the early investors and a well-known community member.

The known sponsors are: Marc Bettinger, Achim Heiniger, Denzel Schwimmer,  Tristan Turner, Khaoudy Yassin and some more sponsors which decided to stay anonymous.

IOTA has a big healthy community of voluntarily working people and sponsors that are unified and goal-oriented in bringing the technology to life.

The ecosystem fund is meant as a development booster to attract creative thinkers, developers and the possibility of funding people’s ideas if they are beneficial for IOTA.

The IOTA foundation announced in the official blog post a selection of possible applications in the following fields:

  • Proof of concepts
  • The creation of Libraries/Modules
  • Research and development of new IXI Modules
  • Tutorials for
  • Hackathons

But there is more to it!

You could work on a coordinated marketing campaign, you could ask for specific projects that are not covered by the former list.

I’m pretty sure that the founders are open-minded and like to hear lots of ideas because that is the very purpose of this fund!

Therefore, I want to encourage everyone with a good idea to apply for a funding!

Your application can be submitted here: FORM

April Report #3

April Report #3

The second half of April in the IOTA-zone offered access to interesting background development and additionally one moment for the history books.

We saw interesting articles, a few interviews and what’s about to come.


First of all some partial results of the first and second stress test.

The dev-team around Dominik Schiener set up a small homepage to watch the stress test in realtime:

While reaching a Transaction per second (TPS) of max. 127 TPS (peak) in the first round, different scenarios were simulated and the test-net heavily loaded.

A small data frame gives more info about the values that have been measured.

If you are interested developer, then you may take a look at the appropriate Git:

The second and bigger test revealed a first picture of what the tangle can become, once more nodes are in the network.

The test-net reached a number of almost 230 TPS(!) which is more than the thirty fold of what Bitcoin can handle at the moment. Bitcoin is running on 7 TPS right now, without adding the problems of the problematic block size of this Blockchain.

The difference to all other projects that brag with big numbers is that IOTA actually tested it in a natural and global environment, not theoretically. All real  Problems involved. This is credible proof instead of talking.

Here are no transaction fees involved and the network can only get faster the bigger it grows. A novelty!

That being said: I’m really curious what happens when the tangle grows to a network with thousands of nodes. The scalability is incredible and held what it promised so far, what a great show!

The dev-team is planning a 1000 TPS stress test already. so we can expect more test results, further improvements and in the end hopefully a meaningful report of all measured values. update restructured their side and added Spanish to their languages.

They depend on donations so think about sending them a little obolus for their free and important service!

Internet of Things Summit in Brussels (19th and 20th April)

After countless participations, Dom again visited a highly recognized IoT conference, this time in Brussels.

Thanks for your efforts!

He told us, that we can expect further info when he has time to spare.

One little but important supplementary note: Huawei, yes, that Huawei mentioned him and IOTA.

Free advertisement and a fruitful reward to all his participations in conferences.


Possible second Big Deal!

We don’t know much, but there is possibly a second big deal on the horizon so “whales” are called to contact David in the official Slack and to discuss your potential donation.

Note: This is not a decrease of your funds, this is a smart step for your investment because the involved companies certainly add more value to IOTA than you lose with a donation to this early point of IOTAs adoption! 

My opinion (but I’m certainly no whale): Do nothing, and lower your ROI! Whatever you do, of course, it’s your money but this is just a wonderful opportunity, so think about it!



I don’t need to add anything here, just read for yourself!



In the escrow-based trading slack YDX ( info under people are buying as if hell is breaking loose.

We already reached a price per Gi of 0.034 BTC meaning that we already broke the 100 million market-cap.

Before official listing on a trader. This is truly incredible. 

However, we have to keep in mind, that not all tokens are claimed. That means that the total market cap is lower as it is shown on YDX.

At least ~300 Ti are not part of the trade right now, so much room for additional trades. Enough IOTA for everyone!

Thanks for reading,

have a good week!

April Report #2

April Report #2

I know, this update comes pretty fast after April Report #1, but that is the IOTA-sphere these days, progress everywhere!

Again a great IOTA Foundation-update:

Welcome, Wilfried Pimenta de Miranda!


Mr. Pimenta de Miranda lives in and around Oslo, Norway and is a working with new emerging technologies and disruptive systems for progress.

On his LinkedIn profile, he writes:

I shape strategic innovative ventures and initiatives that open new pathways to value creation and growth models for business and society. I bring disruptive digital technologies to life: Blockchain / Distributed Ledger Technologies, Artificial Intelligence (AI), Internet of Things (IoT) and Internet of Me / MyData. Together with a team of world leading technologists and industry thought leaders, we empower true innovators ready to transform their industries and organizations from eHealth, Transactive energy systems, Smart cities, connected/autonomous Mobility, Shipping & Logistics.

The IOTA ecosystem and the foundation are clearly gaining traction because they are able to acquire such professional experts like Mr. Pimenta de Miranda.

After last week’s addition of Regine Haschka Helmer plus the already existing circle of advisors and core-devs, we already have the most promising crypto-enterprise at hand.

I know that hype isn’t very appreciated, but it’s pretty hard to suppress with this frequently dropped high-quality news!


IOTSummit 2017 with IOTA

For any other crypto, this would be an enlightenment, for IOTA this isn’t the first solid opportunity to present its unique features.

Still, the IOTsummit is one of the most important places to be for innovations on an international stage.

The European summit will be, again, and yes I know I use this word often, a great opportunity to showcase IOTA to bring more solid companies into the ecosystem.

These are the best news!

New IRI and stress-test

Improvements of the IRI are beeing tested and deployed, once the stress tests are done and important measured values are taken.

That will be the moment when IOTA reaches an important milestone: the scalability will be tangible.

The difference of the main net (1st picture) and the test net (2nd picture) is incredible right now.

That may be partly explainable because a big share of main net-spammers is currently used in the test net.

Still, the overall transaction confirmation-rate seems to be pretty high

There is a new Tangle-explorer made possible by @Scottjp and the help of @utamaro and also @raganius!

This clearly arranged explorer is a nice addition to the existing explorer

Both explorers are important and necessary to handle the needs of a lot of people once, IOTA is adopted widely.

And interesting for speculators:

A nice price chart plus market cap: made by @wilowfoot

The next weeks will be very interesting as rumors say that we get news on the official exchange listing when the stress tests are done.

Have a nice day,


The incredible January Part 2

The incredible January Part 2


It is time!

The next big milestone was reached yesterday when the Light wallet was announced for open Beta!

You can download the official Full/Light-wallet GUI here: Light wallet

More about the release by Dominik Schiener:

If you are looking for a node to run the Light wallet, is the right address.

There you can find a growing number of nodes, which are online 24h a day / 7 days a week and set up solely for this purpose.


That means, that the list of things we need to have a successful exchange listing is finally completed.

This list was given by the devs in Octobre:

That doesn’t mean that the list won’t grow from here, we likely see a mobile wallet announcement soon. is working on that, and AFAIK it’s already been tested.

Still, we can expect the exchange listing everyone is waiting for, very soon. 


Since IOTA is a community-based project, CORE is encouraging every developer to step up and create a working proof of concept for IOTA to show the technology.

For that, you don’t need to have extraordinary skills and knowledge about IOTA and its intrinsic functions, you can just use the newly released sandbox environment

If you want to take a look at the sandbox, you can follow this link


You need inspiration for a proof of concept?

Here we go: POC



To draw a conclusion: 2017 started tremendously for IOTA!  Part 1

The core dev team and strategic management again have shown their extraordinary skills and made IOTA what they told they would.

Now, the next phase of IOTAs path can start, real use-cases.

IOTAs success will depend on these use-cases so I can only encourage everyone who is skilled to code a line or two: built something and become a part of IOTA!

You won’t regret it!


Have a nice day,

The incredible January

The incredible January

Hey Folks!

Lots of important stuff has happened since my last entry so time to sum it up for you! Fasten your seatbelts, IOTA is on its way to launch its rockets!


Light wallet is already in beta test

-The light wallet is already completed and beta tested while I’m writing. With this wallet, people are able to work with IOTA, conduct transactions and claim their IOTA’s but they don’t need to manually add neighbors. They just need to add one peer to be connected to the main net. This software is a big step to connect to a broader range of people especially if they are not that tech-affine or interested in spending too much time on adding neighbors.
As this service is not the focus for IOTA’s future in hindsight of its machine-economy, it is very important to get more people on board.
One successful point on the list to get ready for official exchanges.

Free server for the coming light wallet:

-@moodledidoodledi and @scottjp as the owner of are happy to announce a newly set up server to provide users of the light wallet with a peer-IP. is proudly supported by and would be grateful to get donations to keep up the support and service they provided for months now! became a reliable source of information and provided help for countless people, so let’s help them out! These guys deserve it!

Mobile wallets are also beeing tested 

Needless to say that this mobile wallet is a big important addition to the software spectrum, the community has created. Great work Oliver, Sascha and Adrian!
The team behind provided us with an important piece of software on the long road to mass adoption and the listing at exchanges so if you can spare a coin or two,
donate and show them some love!

@bahamapascal set up 6 nodes for a better network.

On behalf of the Blockchain research lab, Pascal took his time to set up 6 additional nodes for a better connection within the tangle. Great work!
If you struggle to find enough peers for your wallet, pm @bahamapascal in slack and share your (if possible) static-Ip with him to be a part of the tangle.

This also applies for all members of #nodesharing in the slack. If you need peers, pm people in nodesharing and share your IP.

The server costs were supported for 2 months by so I’m pretty sure Pascal would also be happy to get a few coins for his support and efforts for the upcoming months of support!

IOTA C# implementation.

Tomer Krisi (@Artik123) delivered an incredible piece of work: He just ported IOTA to C-Sharp.
This is a BIG step towards a better distribution, getting more developers into IOTA . Also: this was voluntarily done. What a great job!

New foundation-members

-Chris Skinner joined the IOTA foundation as an advisor! This is an invaluable addition to the already astonishing expertise, the IOTA foundation managed to bring together.

Also: Navin Ramachandran joined the IOTA Foundation: priceless!



-A new OTC bot provided with the excellent service of Yassin (@yassinnxt) is life to enable trading before IOTA is listed on official exchanges.
@come-from-beyond took his precious time and integrated this bot in slack.
This service was set up to provide a temporary solution as CORE is occupied with important tasks behind the curtain. The bot is pretty cool considering the automatic features it provides.

The OTC-bot service assisted by Yassin works as follows:

1. You send BTC or iotas to an address provided by Yassin (via private message)
2. Yassin executes a command to deposit the accordant amount to your balance tracked by the bot
3. You buy/sell iotas (this can happen as many times as you need)
4. You send Yassin an address to withdraw the earned BTC/iotas
5. Yassin adjusts your balance and sends real tokens to your address
6. Trades are taxed with 0% fee.
7. Deposits/withdrawals are charged with 1% fee (rounded up).
8. Min amount of a deposit/withdrawal is 10’000 microBTC/2 Gi.
9. To get instructions on how to trade iotas once you get your tokens on the balance type “HELP” on #trading channel.
10. As a precaution, you are advised to provide Yassin with an extra BTC and IOTA-address to be able to receive your funds once you left slack for different reasons, such as a ban or technical issues.
11. For each IOTA deposit, a new address must be generated. This is necessary to show the right balances for each entry listed by the bot.
12. For better usability, Gi and microBTC for fees are always rounded. (1Gi for 2GI-100Gi, 2Gi from >100Gi-200Gi and so on)

The service was tested with test tokens, but it is still possible that an undiscovered bug may lead to a loss of all your BTC/iotas, so we suggest to trade small amounts per session.


1. Alice contacts @yassinnxt and says “I want to deposit 50 BTC”
2. She sends 50 BTC to an address provided by Yassin
3. Once 50 BTC are confirmed, Yassin types “GIVE 49.5 BTC TO @Alice (1% fee included)
4. Alice contacts Yassin and says “I want to withdraw 200 gigaiotas (Gi)”
5. Yassin executes “TAKE 200 Gi FROM @Alice”
6. Yassin sends 198 Gi to Alice
7. Alice contacts Yassin and says “I want to deposit 200 Gi”
8. She sends Yassin 200 Gi
9. Once 200 Gi are confirmed he types “GIVE 198 gigaiotas TO @Alice” (1% fee included)
10. Alice contacts Yassin and says “I want to withdraw 50 BTC”
11. Yassin types “TAKE 50 BTC FROM @Alice”
12. Yassin sends 49.5 BTC to her (1% fee included)

Also worth mentioning: 

-The newly created sandbox beta can be tested in #sandbox-beta

-@bahamapascal and @strongwares created a node-sharing manager. I will deliver more info about that when I tested this tool myself. Great work!

-Dom wants developers to start coding real PoC for bounties! If you are interested: Go into Slack and offer your help and I’m pretty sure he can provide you with some inspiration!

If you are capable and creative: Take this chance and become a part of IOTA! You won’t regret it.

Blockchain research!

The Blockchain Research Lab of the University of Hamburg is pleased to announce the first of our Blockchain Monitor surveys. It forms the basis for creating a sentiment index about blockchain use cases in finance.

Please help the Blockchain world by completing this survey:

(and, of course, we would greatly appreciate if you help us to spread the link) – here we go!


So, all in all, we saw an unprecedented month so far and it’s just the 16th of January so I’m pretty excited to see the rest of it!

If you have questions or additions, feel free to contact me in the Slack at @limo

Have a good day!




Happy Holidays and a Happy New Year!

Happy Holidays and a Happy New Year!

Dear readership,

2016 was an exciting year for IOTA, an exciting year for me and the birth of

I want to thank all of you for all the constructive criticism and helpful comments for this blog.

I’m really happy and cannot really put into words, that has had over 10.000 views since Octobre 28th. Which is far more than I have imagined and shows the interest IOTA has attracted.

Thanks for that!

I hope that your year was as interesting as mine and that you have a few days to celebrate Christmas or just a few days with your families and friends!

Hopefully, 2017 will be a year full of good surprises for all of us!

Happy Holidays!


[German] IOTA: Die Internet-der-Dinge Revolution

[German] IOTA: Die Internet-der-Dinge Revolution

Das Internet-of-Things (IoT) ist keine Träumerei mehr. Längst werden sämtliche Geräte an das Internet angebunden. Hierbei sind Philips Hue, die Oral B Smart Brush oder per App steuerbare Heizungen nur noch die Spitze des Eisbergs. Die Liste der Geräte ist so groß wie die Zukunftsvision: Der Kühlschrank, der selbst Essen nachbestellt oder das Auto das minutengenau den Parkplatz bezahlt – bald soll jedes Gerät aus dem Alltag mit anderen Geräten selbstständig kommunizieren und diese auch bezahlen können. Der Nachfrage wäre gigantisch, die Zeiteinsparungen enorm. Aber mit technologischem Fortschritt geht immer zunächst ein Sicherheitsproblem einher. Erst kürzlich wurde eine große Anzahl an IoT-Geräte gehackt, um eine gebündelte DDos-Attacke auf Twitter, Github, AirBnB & Co. durchzuführen. Es wird also eine Technologie benötigt, die die Geräte sicher untereinander kommunizieren lässt und im Optimalfall auch noch ein Zahlungssystem bereitstellt, sobald monetäre Transaktionen innerhalb des IoT durchgeführt werden müssen. Genau diese Technologie ist IOTA. Doch bevor man das Konzept hinter IOTA verstehen kann, muss man zuerst die Blockchaintechnologie und Bitcoin verstehen.

Blockchain, Bitcoin und deren Limits

2008 wurde anonym ein Whitepaper veröffentlicht, welches ein schnelles und dezentrales Zahlungssystem basierend auf dem Internet vorstellte. Die Rede ist von Bitcoin (Abkürzung BTC oder auch XBT), der Onlinewährung, die am heutigen Tag ~700$ das Bitcoin kostet und weltweit monetäre Transaktionen innerhalb weniger Minuten ermöglicht. Bitcoin ist komplett dezentralisiert, d.h. es unterliegt weder Entscheidungen von Regierungen oder Banken, noch kann es ausfallen. Alles ist im Programmcode genau festgelegt und funktioniert über synchronisierte Peer-to-Peer Verbindungen. Transaktionen werden hierbei in sog. Blocks gegliedert, die wiederum aneinandergereiht werden (daraus entsteht die sog. Blockchain). Die Weiterverarbeitung des jeweiligen Blocks erfolgt durch einen sog. „Miner“, also Computer von Menschen, die über eine Peer-to-Peer Verbindung miteinander verbunden sind. Miner haben mehrere Aufgaben. Zum einen stellen sie die Rechenkraft, um neue Blocks zu generieren. Denn es gilt: der intrinsische Gegenwert eines Bitcoins wird initial durch die Stromkosten des Miners gestellt. Dabei stehen die Miner untereinander im direkten Wettbewerb. Es kann beliebig viele Miner geben. Der Wettbewerb besteht darin, mit dem Computer eine Rechenaufgabe zu lösen – hierbei ist relevant: je mehr Rechenleistung (Hash-Power) desto wahrscheinlicher, dass man die Aufgabe löst. Jedoch passt sich die Schwierigkeit der Aufgabe der Gesamtrechenleistung aller Miner an) um den nächsten Block zu minen. Wenn sie sich erfolgreich gegenüber den anderen Minern durchgesetzt haben erhalten sie alle Transaktionsgebühren aller Transaktionen, die in diesem Block enthalten sind sowie einen Bonus (durch den Bonus entsteht eine festgelegte Inflation; Der Bonus nimmt über eine definierte Zeitspanne ab, bis er schließlich Null erreicht).


Eine weitere Aufgabe eines Miners ist, die Hash-Power des Netzwerkes dezentral aufrechtzuerhalten. Selbige darf nie über 50% bei einem Miner liegen, da sonst eine “dominante” Blockchain gebildet werden kann, die ab dem Zeitpunkt weder dezentral noch sicher ist. Eine breite Aufteilung der von Minern gestellten Rechenleistung ist also eine Grundvoraussetzung für eine sichere Bitcoin-Blockchain.
Es können maximal 21 Millionen Bitcoins generiert werden. Diese Anzahl klingt gering, wird aber durch die hohe Anzahl an Nachkommstellen ausgeglichen. Die kleinste Einheit beim Euro ist Cent. Beim Bitcoin wird selbige Satoshi genannt (nach dem anonymen “Erschaffer Satoshi Nakamoto”). Ein Satoshi ist dabei gerade mal 0.00000001 BTC, also ein hundert Millionstel eines Bitcoins. Auf diese Weise kann selbst bei einer ernormen Wertsteigerung und einem Währungsersatz auf globaler Ebene mit kleinsten Werten gehandelt werden.  
Wie wird nun die Sicherheit in einem solchen Netzwerk garantiert? Eine wichtige Rolle spielt hierbei die Verschlüsselung der Blocks mithilfe eines Hash-Algorithmus. Solche Hashes sind praktisch nicht zu entschlüsseln, denn der Aufwand steht in keinem Verhältnis zum Nutzen. Somit ist die Blockchain rückwirkend nicht mehr veränderbar. Um die Bitcoin-Software nutzen zu können, muss daher jeder Nutzer zunächst die gesamte Blockchain herunterladen. Diese authentifiziert dann den Nutzer gegenüber anderen Nutzern im Bitcoin Netzwerk. Dieses Verfahren lässt nur eine Schwachstelle offen: Die Schnittstelle Software <-> Nutzer.

Basierend auf diesem Konzept gibt es zahlreiche weitere dezentralisierte Währungen, die sich auf unterschiedliche use-cases spezialisiertert haben: Ethereum, Dogecoin, Nxt, Steem und viele weitere. Nicht alle streben dabei einen Währungsersatz an, sondern nutzen die Blockchain-Technologie für Datensicherung, Anonymität oder das Internet der Dinge. Diese und auch Bitcoin selbst haben jedoch aufgrund der zugrundeliegenden Blockchaintechnologie zwei entscheidende Nachteile. Zum Einen die Skalierbarkeit: Je mehr Transaktionen durchgeführt werden, desto mehr Probleme bekommt ein Blockchain-Netzwerk. Durch die steigende Anzahl an Transaktionen, wird der Platz innerhalb eines Blocks ausgereizt. Diese Blockgröße führte jüngst zu der nachhaltigen “Blocksize-debate”, die dem Bitcoin noch immer vor einige Probleme stellt, die bisher nicht gelöst sind. Die Blockgröße muss also mit dem erhöhten Aufkommen von Transaktionen steigen, das jedoch tut sie bisher nicht. Der größte Nachteil allerdings sind die Transaktionskosten, die benötigt werden, um die Weiterverarbeitung von Blocks zu garantieren und zugleich als “Spamschutz” dienen, um das unnötige Verbrauchen von Block-Platz einzudämmen. Hierdurch werden Mikrotransaktionen, für die es einen stark wachsenden Bedarf gibt, unwirtschaftlich (als Beispiel: Ein Nutzer möchte eine Transaktion über 0,00001$ durchführen, aber die Transaktionsgebühr kostet 0,07$). Diese Nachteile machen die Blockchaintechnologie zur Anwendung im Bereich IoT unattraktiv. Wie also eine sichere Kommunikation sowie eine schnelle Bezahlung im Bereich IoT sicherstellen?

Die Lösung: IOTA

IOTA löst die Probleme der Blockchaintechnologie und besitzt zugleich dieselbe Sicherheit, mehr sogar: denn IOTA ist Quantum-Computer resistent, als erste Technologie seiner Art. Je mehr Transaktionen, desto schneller wird das IOTA Netzwerk. Auch sind Transaktionen komplett kostenfrei. Der Unterschied zu herkömmlichen Cryptowährung liegt hierbei in der Verwendung eines Tangles statt einer Blockchain. Die Transaktionen sind in einer Art Strang angeordnet, wobei jede Transaktion zwei vorhergehende Transaktionen bestätigt. Hierdurch entfällt die Notwendigkeit der Weiterverarbeitung von Blocks und somit auch die Transaktionsgebühr. Es gibt keine eingebaute Inflation.


Die Skalierbarkeit ist also ein großer Vorteil des Tangles. Auch das Minen neuer Blocks entfällt. Eine Mehrheitsattacke, bei der über 50% der Hash-Power bei einem Miner liegen, ist somit nicht möglich.
Bedenkt man die schier grenzenlose Anzahl an Geräten innerhalb des IoT, ist die Anzahl an Satoshis im Bitcoin-Netzwerk zu gering angesetzt, um in Zukunft jeden Bedarf zu decken. IOTA hat daher eine signifikant höhere Anzahl an kleinsten Einheiten vorgesehen.
IOTA stellt also die ideale Technik zur Verwendung im IoT Bereich zur Verfügung. Zurzeit befindet sich IOTA noch in der Entwicklungsphase, doch bereits jetzt haben zahlreiche Firmen Interesse an der Blockchaintechnologie 3.0. Es wird erwartet, dass IOTA noch Ende dieses Jahres an den Crypto-Börsen gelistet wird.

Internet der Dinge und Mikro-Bezahlungen mit IOTA

Mikro-Bezahlungen sind geringe Geldbeträge, die, um kleine Handel durchzuführen, im Bereich von 1 Cent bis 5 Euro durchgeführt werden. So wie Kaffee aus dem Automaten, Mp3-Lieder Download oder zeitweilige Medienlizenzen bei Amazon-Prime, am besten vom Auto aus.

Diese Käufe stellen bestimmte Ansprüche an Anbieter, um die Nutzer ohne viel Zeitaufwand und sicher das jeweilige Produkt erwerben zu lassen.

Wikipedia liefert eine anschauliche Liste an Bedingungen, die ein solches System optimalerweise liefern muss.



Entsprechende Zahlungssysteme wurden immer weiterentwickelt. Eins der bekanntesten ist Paypal, doch auch pre-paid Systeme oder NFC-Zahlsysteme finden immer mehr Anwendung in den Märkten.
Dabei ist zu beachten, dass keines der Systeme in der Lage ist, alle Anforderungen abzudecken.
Es finden sich weder vollständig betrugssichere Systeme, noch sind alle schnell im Bezahlvorgang.

Ein optimales System müsste also in der Lage sein, alle oben genannten Anforderungen zu liefern.

Da IOTA, im Falle einer breiten Martakzeptanz, über ein redundant ausgelegtes Netzwerk verfügt, wäre der Tangle extrem schnell. “Portemonnaie-Programme” auf mobilen Endgeräten machen das Bezahlen in nahezu jeder Lage zu einem Arm-wink, sodass die IOTA’s in wenigen Sekunden verschickt würden.

Die Idee: Transaktionen sollen immer möglich sein, auch wenn die Beträge extrem klein sind. Da IOTA keine Transaktionsgebühren verlangt, eine Selbstverständlichkeit.
Die Sicherheitseigenschaften des Tangles sind zudem ein Garant dafür, dass das System unknackbar ist.
Die Dezentralisierung verhindert Systemausfälle und die Implementierung der Open-source Software ist für Unternehmen eine Leichtigkeit.
Da IOTA besonders für das Internet der Dinge geschaffen wurde, ist es natürlich im Bereich der industriellen Sensortechnik interessant, welche Sicherheitsprotokolle voraussetzt.

Internet der Dinge und Sicherheitsprotokolle mit IOTA

Jüngst wurde, wie bereits erwähnt, das bestehende Netz an Geräten missbraucht um sogenannte Distributed-Denial-of-Service Attacken (DDoS) auf besondere infrastrukturelle Punkte im Web durchzuführen. Diese Attacke übernimmt die Sendefähigkeit von zahllosen angebundenen Geräten und nutzt diese, um gemeinsam bestimmte Server anzusprechen. Das führt in den meisten Fällen zu “Datenstaus” und Ausfällen, da Attacken dieser Größenordnung Teile des Internets einfach blockieren können.

Das war möglich, weil die Vernetzung von Milliarden Geräten ohne die notwendigen Sicherheitsgrundlagen im Fokus der Industrie stand, die Abschirmung vor schädlichen Zugriffen jedoch nicht.

Ein unknackbares Sicherheitsprotokoll ist also unerlässlich. Der gerichtete azyklische Graph: Tangle von IOTA ist aus diesem Zweck so konzipiert worden, dass Ausseneingriffe nicht mehr möglich sind.


Selbst Zukunftskonstrukte wie der Quanten-Computer trifft bei dem synchronisierten Tangle auf Widerstand, sodass IOTA das einzige System ist, welches auch auf diesen Fall vorbereitet ist.

Anwendungsfälle für IOTA sind somit nicht mehr auf einzelne Dinge begrenzbar. IOTA bietet die Technologie um nahezu alle vernetzten Systeme sicher und schnell zu ersetzen. Egal ob Sensortechnik, Datenabfragen, Zahlungssysteme, Sicherheitsprotokolle, adaptive Systeme zu Energieeinsparungen oder Integritätssysteme zur Betrugsprävention.

Die schiere Anzahl an Möglichkeiten ist der interessante Aspekt, der IOTA zu der interessantesten Technologie 2016 macht.

IOTA befindet sich momentan in der Beta-phase, in der hunderte Tech-Interessierte an dem Aufbau des Netzwerkes mitarbeiten, Probleme besprechen und “Proof-of-Concepts” entwickeln, bevor es dann vermutlich noch Ende 2016 gehandelt werden kann. 

Die Gründer David Sønstebø, Dominik Schiener und viele weitere leisten dabei beispielgebende Arbeit, um das Ökosystem IOTA nachhaltig aufzustellen und das Internet der Dinge zu revolutionieren.

Es bleibt daher abzuwarten inwiefern 2017 das Jahr von IOTA wird, wir sind gespannt!

Sustainability through Innovation

Sustainability through Innovation

Hello world

Let’s draw a link between sustainability, which is the challenge of the 21. century, and innovation in the realm of the Internet of Things and Blockchains.

Bitcoin’s success was a combination of a pioneer-technology paired with the possibility to change the world’s financial problems; a solution where one currency replaces others.

Cryptocurrency as an object of speculation also generated several bubbles within the last years. Not surprisingly, many people’s involvement was incentivized by money, or worse, greed.

The diversification and evolution of Blockchains, however, lead to new fields where the incentive became innovation itself.

Sustainability in the field of IoT and Blockchains can be an important part of the challenges of the 21. century.


The Anthropocene

A good start for understanding the responsibilities of the future is to outline what has happened in the past and what will happen in the future; in this way, the history of mankind is important in understanding our recent issues.

This expansion is, other than seen in the animal kingdom, not necessarily driven by survival. Humans tend to take everything, wether they are required or not.




The industrial revolution and the time that followed, including electrification, was and is the main reason scientists refer to the Anthropocene. The age, when humans became a part of the stratigraphic geology of the earth.

As part of this transformation, the energy consumption rose exponentially .

The extreme hunger for energy lead to the climate change, a problem people in the western world are still trying to fathom. Then there are people with no access to education or those who just don’t care.

While the carbon dioxide levels are rising, we still raise our annual energy consumption to new levels and run our power-plants with coal and natural gas.

Fortunately, we have an agenda in turning this problem into a solution.


The Energy Transition

“China set a world record, again, in 2015 by adding more installed capacity of both wind and solar in a single year than any other country (32.5 GW of wind and 18.3 GW of solar). By the fourth quarter of 2015, China overtook Germany with the largest installed capacity of solar power in the world (with a total of 43 GW).”
Heinrich Böll Foundation, 2016


One strategy to curtail the consequences of the climate change is the transition from fossil to renewable energy resources like wind-, water- and solar-energy.

The need of these new resources is revealed when we take a look at the carbon cycle of the earth, which is significantly affected by human emissions ( figure 1 below,

Approximately 9 billion tons of carbon a year are emitted by human activities.




The continuing industrialization beginning with the western world, which is now spreading through countless developing countries demands new solutions on a global scale, not just in certain areas of the world.

As mentioned, the first step is and will be the energy transition. The upcoming demands of billions of renewable energy-systems, the industrial transition to better technologies, in general, generates millions of new jobs and opportunities for the economy.

Considering the remaining need of heavy construction vehicles in the field of heavy industries, it’s likely to say that this energy transition will take time.

The economy will still depend on fossil resources as these systems are multi-spherical and not easy to change.

One way to accelerate this infrastructural transition is to change the energy-consumption on a local or personal level in our daily lives.


Intelligent consumption


Here is where innovative Blockchains can make a difference.

Let’s imagine a system functioning on a Blockchain, which is able to reduce the energy-consumption worldwide.  This system is able to replace countless other systems, where energy would be wasted.

This system would also be decentralized to prevent it from being captured or turned off.

A distributed network where a political decision wouldn’t matter because of no institution but the connected peers had the authority to change its behavior.

The first non-political system on a global scale, to unite humanity and to improve the life of billions of people.

Millions of sensors would observe climate conditions and as a consequence adjust climate control systems so that energy wastage would be prevented effectively.

These adaptive systems could be installed everywhere and on any device. The most prominent use-case would be adaptive streetlights.

We don’t need light were no one is walking or driving, so why wasting energy?

The installation of these innovative solutions could spare a lot of energy and money. As a positive feedback-loop of sustainability, this money could be used to built even more

renewable energy facilities.

Another big part of an environmentally friendly system would be to observe and detect humidity levels in soils.

Big agriculture farms are usually in sunny regions but as a matter of fact, sunny regions often cope with low levels of subterranean water which is not regenerative and decreasing fast (Figure 2, USGS).




Humidity-adaptive systems for modern irrigation of agriculture are therefor the only solution.

In the end, it’s the peoples choice to support those systems and the become a part of it.

To close the circle: Blockchains can be and will be an important part of the future and even if this vision is given with an aftertaste, not all Blockchains or tangles are the same!


Have a great day,
