Im Gegensatz zu bitcoin, das auf einer basiert, baut IOTA auf dem Tangle, einem , auf. Dieses „Gewirr“ benötigt(e) bisher Koordinatoren, die das Netzwerk schützen sollen. Dementsprechend heißt es :
Um das Netzwerk wachsen zu lassen und es vor bestimmten Angriffen zu schützen, setzt IOTA derzeit auf einen Koordinator. Der Koordinator prüft gültige Transaktionen, die dann das gesamte Netzwerk validieren. [Er] wird von der IOTA Foundation in einer Mehrfachsignatur geführt. Der Koordinator kann nicht abtrünnig werden, da ihn das gesamte Netzwerk überprüft und validiert. [Selbiger] gibt periodische Meilensteine aus, die sich auf gültige Transaktionen beziehen. Im Mainnet werden diese Meilensteine minütlich ausgegeben.
Diese Meilensteine benötigen bisher die Mithilfe des Koordinatoren. Dieser soll sich nun bald verabschieden.
Kein Koordinator, keine Probleme?
Der Koordinator dient letztlich als zentraler Validator. Er entscheidet, ob die jeweiligen Transaktionen Gültigkeit haben bzw. ob sie nicht den Versuch eines entspringen. Da dieser Koordinator dem IOTA-Netzwerk jedoch immer wieder den Vorwurf der Zentralisierung einbringt, soll dieser nach und nach aus dem Tangle verschwinden. Dazu hat die IOTA Foundation nun ein TestNet veröffentlicht, das ohne diesen auskommt. Das bedeutet letzten Endes, dass IOTA ihrem Ziel, ein vollkommen dezentrales Netzwerk darzustellen, ein Stück näher kommt. So heißt es in der :
Dieser [der Koordinator] dient als Schutzmechanismus, während das IOTA-Netzwerk in die Richtung der nötigen Teilnahme wächst, die benötigt wird, um das Netzwerk in dezentraler Art und Weise zu 100 Prozent sicher zu gestalten. Dort kommt der Distributed-Konsens-Mechanismus des Tangle ins Spiel.
Und dieser wird künftig ohne den Koordinator auskommen. Zunächst jedoch im ZNet, also der Testumgebung für die nicht (von einem Koordinatoren) überwachte Validierung im IOTA-Tangle. Nutzer sind dazu aufgefordert, dieses ausführlich zu testen. Und zwar indem sie einen CLIRI-Node betreiben und dem IOTA-Team etwaige Verbesserungsvorschläge zukommen lassen.

Australian Solar Startler Power Ledger thinks that Blockchain Technology can stimulate the energy industry to more efficiency, reducing both distributor waste and consumer costs.
Since finalizing its initial offer of 34 million Australian Dollars (ICO), the company has participated in several blockchain studies, including one financed by the Australian government.
Power Ledger was co-founded by Dr. Jemma Green, a researcher at Curtin University in Western Australia. Before setting up his Power Ledger, Dr. Green worked as an investment banker at the JP Morgan subsidiary in London, where he also received two postgraduate degrees from Cambridge University in the field of sustainability. Dr. Green was also freshly elected as Deputy Mayor of Perth, Western Australia.
Dr. Green spoke to the CCN about the challenges of disrupting the energy industry with blockchain technology, as well as about the launch of the first ICO in Australia.
CCN: Dr. Green, you have a charming summary, at least. What prompted you to leave the investment banking industry and start developing blockchain-based solutions for sustainable energy?
Jemma Green: Halfway through JP Morgan I looked encompassing the office and noticed that there were no recycling facilities. I glanced at it and found that 500,000 pounds a year could be saved from their enlightenment, so I threw this concept to COO in Europe, and he said well. Three months later we launched recycling boxes, and I was very excited until I saw that people were recycling in their office boxes. So I formed a secondary phase called “Bin The Bin,” and I shifted the ugliest person in the office.
Something overturned my mind at that moment, and I found that renewable energies are more exciting than my daily work, so I decided to pursue the study of sustainability.
CCN: What will be the role that blockchain platforms, such as Power Ledger, will play in the future of the energy industry?
Jemma Green: Blockchain platforms will support to facilitate our future energy distribution with the better return on investment for solar panels and batteries. It also allows for a low-cost, low-carbon energy system that sets the client in the first place.
Clients will have more authority over their functionalities, as well as a better knowledge of their energy profiles.
CCN: What are the vast barriers that Power Ledger and other energy companies face when trying to decentralize the energy industry?
Jemma Green: There are a lot of adjustments in the field of the energy industry, so it is indeed an obstacle. The most challenging part is finding a way to work within the rules, while disturbing sector – it is a balancing act, but one that we managed through partnerships.
By saying this, there are limited incentives in specific markets for a market that needs to innovate on a platform like the Power Ledger.There is also a massive educational process that has to happen so that purchasers understand their choices when it comes to energy.
CCN: You had an ICO / TGE with great success, mainly since you were the first Australian startup to keep one. What was the most challenging about this experience?
Jemma Green: It was very hard for our resources. I was simultaneously juggling the business while I was also spending 12 hours a day at ICO. Being a startup, everyone has been and still is using multiple hats, so we steadily manage how to spend the best time, making sure that we do not differ too much from our long-term goals.
It’s also hard because you do not need to outsource anything. So we’d be in our telegram chat until 1 am and the dawn break that runs the business. It was imperative for us, as executives, to be involved in the community throughout the ICO process, introducing new customers and leading the company.
CCN: In retrospect, occurs there any aspect of the ICO / TGE you would like to have treated uniquely, or advice that you would give to other companies that are trying to launch token sales?
Jemma Green: Through all the madness, sometimes we were caught reactive preferably than proactive with our official answers. For example, we would be in trenches on our telegram chat!. Talking with each person instead of being strategic and using the voice of the company and getting to it.
We also had crew members radiated all over the globe, which was very good to reach, but brought its challenges. I would advise other ICO’s to prioritize the establishment of an internal connection both in the location and in the discipline.
In retrospect, these things were easy to change, but the reality is that we could not have gotten a better result than what we have achieved.
