IOTA ESP32 Wallet

IOTA ESP32 Wallet

05:33 - 17/08/2019

Now that CClient v1.0.0-beta is released, IOTA can implement a hardware wallet based on it. I will, in this blogpost, briefly explain the architecture of the IOTA Wallet on ESP32 and I will demonstrate the wallet application.


The CClient library is meant to apply the Tangle into IoT ecosystems. It is able to communicate with small devices. The ESP32 is a good candidate because it has built-in wireless connectivity.

But what’s the ESP32?

  • It is a 32bit SoC (System on Chip) based on the Xtensa LX6
  • It is able to operate at 160 or 240 MHz with the memory size of 512KB
  • It provides two development frameworks: arduino-esp32 and esp-idf. Even if both of them are good, I prefer the esp-idf as my development framework since it’s native to the ESP32.

The IOTA ESP32 Wallet

The wallet architecture consists of three parts:

  • Hardware: the Xtensa LX6 processes and peripherals
  • FreeRTOS: real-time system, network, and HAL support
  • Wallet application: IOTA CClient library, SNTP client, and Console service.

The system time will be reset on reboot every time, so we need to get the correct timestamp via SNTP client. The console service allows you to interact with IRI node through the terminal.

Learning by example: IOTA Workshops

Learning by example: IOTA Workshops

17:56 - 13/08/2019

IOTA introduces a lot of new concepts, such as the Tangle and Trinary, which may seem difficult to use. That’s why we have some excellent client libraries that abstract most of the concepts into easy-to-use functions.

To help you start developing with IOTA technology, we created several ‘workshops’ for the C, Go, JavaScript and Python libraries. They teach the most common things you will do with these libraries and give concrete code examples that demonstrate how to do these interactions. The workshops are great to use when you are starting with IOTA or when you are teaching others about what IOTA is and how to interact with the Tangle.

The C workshop

The client library for the C programming language is called “Entangled” and is one of the harder libraries to work with. That’s because it has been written in a low-level programming language.

Low-level programming languages are great for performance. They are good for devices with limited processing power/memory. However, you have to do a lot more yourself when it comes to programming — memory management, for example — which makes it harder to work with over higher-level languages, like Python or JavaScript.

The Entangled client library, built from the ground up by the IOTA Entangled team, can do a lot of things in a lot of different ways. It’s an excellent candidate for a workshop!

The workshop currently consists of examples of how to:

  • Send and receive transactions
  • Check your balance
  • Generate new addresses
  • Send IOTA coins

The C Workshop can easily be cloned from the IOTA Community GitHub. The Bazel build tool is the only dependency you need to get started.

The Go workshop

The Go programming language is a well-performing programming language that has gained a lot of popularity over the last couple of years.

Go is a good compromise between the development of a higher-level language and the performance of a lower level one. The Go Client Library for IOTA offers all the basic functionality you need to interact with the Tangle using Go. This library is actively maintained by the IOTA Foundation and is extensively used in the GoShimmer prototype for Coordicide.

The Go workshop currently consists of examples of how to:

  • Send and receive transactions
  • Check your balance
  • Generate new addresses
  • Send IOTA coins
  • Send and receive multi-transaction messages
  • Utilize a real-time stream of incoming transactions using ZeroMQ

The Go Workshop can be cloned from the IOTA Community GitHub, all you need is Go version 1.10 or higher.

The JavaScript workshop

The JavaScript workshop was the first workshop created — and with a good reason: JavaScript/Typescript is very often used in the IOTA Ecosystem, including the Trinity Wallet software and a lot of the proof of concepts built by the IOTA Foundation and IOTA communities.

JavaScript/TypeScript can be used in browsers (clientside) or servers in combination with Node.js (serverside), which makes it very versatile when integrating IOTA in a web-application.

The iota.js client library is a client library maintained by the IOTA Foundation and written in TypeScript. It will most likely be your best bet when you want to develop something with JavaScript and IOTA.

The JavaScript workshop currently consists of examples of how to:

  • Send and receive transactions
  • Check your balance
  • Generate new addresses
  • Send IOTA coins
  • Send and receive multi-transaction messages
  • Utilize a real-time stream of incoming transactions using ZeroMQ
  • Send and receive data using MAM0 streams.

The JavaScript Workshop can also be cloned from the IOTA Community GitHub repository. All you need to run them is a recent version of Node.js and npm.

The Python workshop

Python is a popular higher-level programming language used for a lot of different purposes, including web development, automation, and data science. It’s easy to learn and work with, and it’s often recommended as a good first programming language to learn. A client library — called PyOTA — is available for IOTA. It covers all the basic functionalities you need to interact with the Tangle.

The Python workshop currently consists of examples of how to:

  • Send and receive transactions
  • Check your balance
  • Generate new addresses
  • Send IOTA coins
  • Send and receive multi-transaction messages
  • Utilize a real-time stream of incoming transactions using ZeroMQ

The Python Workshop can be cloned from the IOTA Community GitHub. It requires Python 3.5 or 3.6 installed on your system to run the examples.


We hope these workshops show you how easy it is to develop something that interacts with the Tangle.

As you might have noticed, these workshops are not part of the regular IOTA Foundation GitHub Organization. They are part of a separate Community Organization.

The current autonomy allows us to easily add community developers — who wish to contribute to the IOTA Ecosystem — to the organization. Someone, for example, who wants to develop a version of the workshop in another programming language or a tool that benefits others in the ecosystem.

We are always open to pull requests for additions or improvements to the existing workshops. We update and extend the workshops over time when new functionalities become available in the various client libraries.

If you wish to add a contribution, feel free to contact Dave de Fijter or Lewis Freiberg on Discord (you can find them in the IOTA Foundation section of the user list). They will add you to the organization.

Welcome Jonathan Shaffer to the IOTA Foundation

Welcome Jonathan Shaffer to the IOTA Foundation

15:58 - 08/08/2019

Jonathan Shaffer joins IOTA as a Senior Electrical Engineer, based out of Atlanta, Georgia, with expertise in programmable logic devices, digital signal processing, and hardware design. He brings with him an extensive background in avionics systems and a passion for all things engineering.

As a teenager, Jonathan discovered his interest in embedded software design after learning MIPS assembly language to hack video games. It wasn’t until much later, halfway through his co-op at Georgia Tech Research Institute, that he would change his focus (and major…) to hardware. He also improved his skills in firmware development for programmable logic designs and peripheral interfaces. Since then, he has expanded his knowledge in systems-level analysis and verification test procedures, which has helped ensure design robustness.

He completed his Bachelor’s of Science in Electrical Engineering from Kennesaw State University and hopes to finish his Master’s when he can find the time to do so.

On Joining IOTA

In May 2019, I stumbled upon an article about the IOTA Crypto Core FPGA. With my interest piqued, I found my way to the IOTA discord and was immediately matched up with the Qubic development team. Needless to say, I have been involved as much as I could be since then. Even with Qubic being my current primary interest at IOTA, I couldn’t help but be inspired by all the other ideas being passed around. Not just the members from the IOTA foundation, but the community as a whole. As a member of IOTA, I look forward to working with the existing high-level talent to make the IOTA vision a reality.

We’re extremely happy to be able to add someone as talented as Jonathan to the Qubic FPGA team. His experience has already caused several breakthroughs, and while functioning as a mentor, he has already up-leveled the entire team. Please give him a warm welcome!

The 5th Cohort of IOTA Ecosystem Development Fund Grantees

The 5th Cohort of IOTA Ecosystem Development Fund Grantees

18:18 - 07/08/2019

Over the last few months, we’ve worked very hard to improve the IOTA Ecosystem Development Fund and to make sure we use the funds in the best way possible to benefit the whole Ecosystem.

Today, the IOTA Ecosystem team is very happy to announce that we have six great new grantees and a brand new EDF website to share with you!

The funded projects range among a full node software written in Go, a new semi-permanode solution, a swift library and awareness building & educational material.

With the help of the grantees, the growth of the IOTA community can be ensured and the current network is strengthened and used to its full potential.

We look forward to seeing the progress of these new projects and will make sure to keep you updated about their development.

Grant Updates

Hornet (€154,500)

Sebastian Fuchs (IoTMOD), Maximilian Hase (muXxer) and Alexander Sporn (alexsporn) are the three founders of “TangleKit GbR”, a company created specifically for building products and providing services based on IOTA technology. Their first service enables fast “Proof of work as a service” for devices with limited computational power and can be found here.

As part of the grant, the three grantees will create an IOTA fullnode for the mainnet called Hornet. It is written entirely in Go and will allow to install and run an IOTA fullnode on low-end devices such as a Raspberry Pi with significantly increased performance.

Sebastian Fuchs, Maximilian Hase and Alexander Sporn are all excited to grow the IOTA Ecosystem even further:

“By supporting the development of different fullnode implementations like IRI, cIRI and Hercules, and also by creating a high performance IOTA transaction spammer with multiple attack strategies, we gained a lot of knowledge about the IOTA technology. We want to give this knowledge back to the community in the form of an optimized open-source full node software.
The main goal of this project is to achieve feature parity with IRI v1.8.0. In addition, HORNET will try to solve currently known bottlenecks which exist in IRI’s implementation (i.e. tip-selection).”

– Fuchs, Hase & Sporn

AION (€56,240)

Olaf van Wijk is a software developer with a broad interest in everything data, security, privacy and AI-related. Some might know him from his work on IOTA-Pay. Similar to many other projects, he was looking for a solution to keep his needed data in the Tangle alive instead of snapshotting it away.

Olaf’s recent work on separating storage & retrieval, as well as his work on path descriptors, led him to a solution for the problem with the ‘Selective Permanode’.

The EDF funds will be dedicated to creating AION, a fully open-source method of managing IRI so that it knows which transactions and solid paths to selectively store.

With the new open-source method, Olaf envisions the following benefits to the wider IOTA Ecosystem:

- Developers can host-specific data relevant for their use-case
- Direct incentive to host your own IOTA node
- Users can ask nodes to keep data alive
- Anyone could host their own application data
- Opens up a financial incentive structure for node operators
- “Self Sovereign Data”
- Self-referencing MAM/Data streams

“After I built a few test applications and proof of concepts on top of IOTA, I kept on running against the same problem: Where has my data gone? Snapshots! It is either: host the entire tangle or delete everything. After my research on separating the API calls from the internal storage of IRI, it struck me!
When AION is finished, I believe it will provide a great boost in IOTA development, and with the EDF grant I can make sure it is open source and available for the entire community!”

– Olaf van Wijk

IOTAKit ($7,000)

Pasquale Ambrosini is an Italian software developer who has been working with iOS since 2010. He is also a very passionate member of the IOTA community. In the past, his work was successfully used in the Trinity Wallet for native proof-of-work and to speed up the address generation on iOS.

With this grant, Pasquale will create a fully written IOTA library in Swift and an example application for iOS devices utilizing this library.

“I think IOTA has made great strides in recent years, but there is still a lot to do and IOTAKit wants to help developers make it easier to integrate IOTA in iOS/macOS applications.
About 40% of smartphones use Swift (iOS). Offering the right tools to native developers means improving adoption, and at the same time simplify the life for developers by making the tools more efficient.
This is IOTAKit, a great library made (with love) from developers to developers.”

– Pasquale Ambrosini

IOTA Developer Essentials and Lab ($8,160)

Petr Zizka (known in IOTA community as Hribek25) is the man behind the IOTA Developer Essentials project.

As a part of the grant, he will complete his self-study onboarding material to cover at least three different programming languages. On top of that, he will set up an IOTA interactive experience lab that turns the self-study onboarding materials into a complete, interactive experience for anyone that wants to get their hands on the IOTA protocol.

“I personally believe in learning-by-doing. I also strongly believe that having top-notch learning onboarding materials is the key attribute to wide adoption and success. I want the IOTA protocol to succeed and this is my contribution to that goal. Thanks to the EDF grant the IOTA interactive lab will be a great addition to the project.”

– Petr Zizka

Everything Tangle — Season 2 ($13,475)

David Florio’s Everything Tangle YouTube channel is widely known in the IOTA community for providing high-quality, educational YouTube videos about IOTA.

To date, the channel has amassed nearly 20,000 subscribers and surpassed 500,000 views. 11 original videos have been published. They cover a wide range of IOTA topics, with the most popular topics being translated and re-released in three additional languages.

For this Ecosystem project, Everything Tangle is currently developing five new videos scheduled to be released throughout the last quarter of 2019. These new productions will discuss emerging IOTA topics and address gaps in public educational resources.

The IOTA Foundation is happy to continue to support Everything Tangle in providing high-quality, informative videos and their mission to inspire, educate and grow the IOTA Ecosystem.

“The goal of Everything Tangle is to create educational content that is both engaging and easy to digest. From inside the IOTA community, it is easy to forget how foreign the concepts behind IOTA must seem to the wider crypto space and the general population. I make my videos in hopes of breaking down that knowledge barrier, so that any viewer can begin to grasp the innovation that IOTA is delivering. As global understanding increases, so too will support and adoption. I am grateful and honoured to continue working with the IOTA Foundation in pursuit of this goal.”

Integrating physical devices with IOTA ($12,000)

Hugo Gregersen (known in IOTA community as huggre) is a hobby developer and IOTA enthusiast. He likes to explore different use cases and to solve everyday problems using IOTA technology. He proved in his previous Coinmonks Medium posts that he is very capable of writing easy-to-use tutorials that can be used by anyone without prior experience in electronics or programming.

The EDF grant will allow Hugo to continue his work on creating awareness and knowledge about IOTA and IOTA development among tinkerers, hobbyists, academia, etc. In addition to writing tutorials, the grant also covers the authoring and publishing of an “IOTA for Dummies” style book that will be available to the community for free.

“I believe that easy-to-use documentation and tutorials are essential for the adoption and success of the IOTA project. If my work can help anyone (especially kids) start playing around with electronics, programming and IOTA, then my main motivation for writing these tutorials has been accomplished.”

IOTA-powered Telco Asset Marketplace: Architecture overview (Part 2)

IOTA-powered Telco Asset Marketplace: Architecture overview (Part 2)

21:36 - 26/07/2019

After reading the first and more business-oriented part of our blogpost, this second part will guide through the technical implementation of our Telco Asset Marketplace and show how it works in practice.

A multi-sided marketplace can only build on a decentralized trust layer. In our prototype marketplace, the trust layer was provided by the IOTA infrastructure.

To build an asset-trading marketplace, we need to develop a number of building blocks, more or less decentralized.

Generic Marketplace Architecture
The result of our work is the first IOTA Telco Asset marketplace PoC. You can play with it here.

For our first PoC (Proof of Concept), we focused on the Orders Management, Settlement and Payments architecture blocks. By storing agreements onto the IOTA Tangle, we keep an immutable trail of which asset is accessed by which Service Provider, without the involvement of any centralized third-party authority. Based on this information, requested payments can be easily tracked and distributed.

The figure below summarizes the different functions available to the marketplace actors, namely Asset Providers, Service Providers and Auditors.

Actors functions

To implement the proposed workflow and to capture each actor data and transactions, the implemented architecture utilizes MAM channels. A digital twin based on the offers, requests and orders data models was defined as the basic structure for every MAM message. As a result, each MAM channel represents an immutable audit trail of asset offers, requests and orders.

MAM Channels were preferred to store data instead of using individual and independent IOTA transactions, for the following reasons:

  • Assets belong to a given Asset Provider, therefore they are unique and need to have associated offers easily linked together. This can be done by posting MAM messages with the current offer (e.g., availability and price) in a dedicated Asset MAM channel.
  • Requests generated by the same Service Provider need to be linked in order to force one request per asset at a time (per Service Provider) and to simplify auditing. This can be done by posting MAM messages with the current request in a dedicated Service Provider MAM Channel.
  • Assets assigned to Service Providers through orders should be linked to the identity of the Service Providers. To this extent, identifiers of MAM Channels (root keys) can be used as a proxy for the identity of Assets and Service Providers. A dedicated Orders MAM Channel maintains this information.

Asset Providers create a new MAM channel for each of their assets. The first MAM message contains details of the asset. All following transactions specify the start and end of a specific offer and link to the successful order (if any) involving it.

Service Providers create a request by specifying the details of the requested asset. A new MAM channel is created for this request. The first MAM message contains details of the needed asset. All following transactions specify the start and end of the specific request and link to the successful orders (if any).

When an order is created, a new MAM message in the orders MAM channel is created to immutably link into the IOTA Tangle the relevant matching asset offer and request.

A matching algorithm runs automatically once a new offer or a new request is created.

Manual matching is also available and can be triggered by initiating a search of assets and offers.

After confirmation of a found match, payments are then processed. IOTA tokens are transferred from the Service Provider wallet to the Asset Provider wallet as soon as an order is confirmed.

Although the current architecture focuses on a restricted number of functionalities, however, we already implemented a notifications service that should simplify integration of third-party building blocks. For instance, this allows a connected Orchestrator to listen for orders creation notifications and consequently configure temporary access to selected assets for service providers.

All APIs have been matched to existing TMForum APIs, in order to simplify such integration with external third party services.

Marketplace Overview

Asset Marketplace walkthrough

For a live demo of the marketplace, check out this video:

The marketplace is composed of two main sections. A Marketplace area (shown below), can be accessed by everybody, without any registration. This area shows the list of currently available asset offers and requests and their details.

Marketplace section

Once a marketplace user logs in, his/her requests and offers are highlighted. By selecting an active offer or request, the system automatically identifies matching requests and offers (if any).

These matches can be reviewed in the other section of the marketplace, the Dashboard page. The Dashboard is only accessible after log-in. (At the moment we provisioned a simple log-in mechanism through Google OAuth ID). From the Dashboard a user can:

  • Fund his/her IOTA Wallet to pay for assets
  • Create new asset offers and requests by filling out template forms that collect the required asset’s (offered or requested) info and to immutably save them with one click onto the IOTA Tangle
  • Managing existing (not expired) asset offers and requests by enabling, disabling, or removing them
  • Generate orders from matching asset offers and requests, and immutably store them with one click onto the IOTA Tangle
  • Automatically send or receive the corresponding IOTA payments
  • Review owned asset history by gaining insights into orders that make use of them and corresponding generated revenues
  • Access transactions’ raw data and explore them using any IOTA Tangle Explorer
Dashboard section

From the dashboard, a user can also access his/her API Key and User ID. These are useful to call the provided APIs from third-party services and to guarantee access to auditors who wish to review existing orders for compliance purposes.

IOTA Benefits

Developing a decentralized, immutable audit trail of asset offers, requests and orders allow all the transacting parties to increase their trust while auditors can gain full transparency and traceability of the process.

Using IOTA for such infrastructure brings additional benefits:

  • The feeless microtransaction structure does not impose any extra cost for the use of this infrastructure, neither does it limit the amount of data and transactions that can be processed
  • The flexible transaction structure allows for the accommodation of various asset descriptions along with offer, request and order data models
  • The permissionless nature allows each stakeholder to host a node and a copy of the ledger, thus removing the single point of failure as well as the need to trust intermediary third parties to provide the marketplace “trust” layer
  • The use of restricted MAM channels protects the confidentiality of the order (who has access to what) and controls the access to the relevant information
  • The IOTA token provides an interoperable payment system.

From PoC to marketplace MVP and MVE

While this PoC confirms the value of an Asset Marketplace, our future work will continue to facilitate development of other elements of this decentralized platform. This is in addition to continuing engagement with an ecosystem of CSPs for the deployment and testing of this marketplace in real testbeds.

If you are an asset or service provider who wants to learn more and help to shape this vision and participate in real testbeds, please do get in touch with (or

On the other end, if you are a technology provider, we would like to understand how your technology can fulfil the requirements of the missing marketplace building blocks. Interesting functionalities will include:

  • Decentralizing asset and service providers organizational identities
  • Decentralizing asset delegation and access
  • Building a reputation system for asset and service providers, leveraging the integration of IoT data to monitor asset use

New business models: how to reduce Telco infrastructure costs and accelerate mobile services deployment

Back in May, the IOTA team attended the TMForum Digital Transformation World event in Nice. The event was organized by the TMForum, a not-for-profit industry association, whose mission is to drive the digital transformation for the future growth of its partners, operating in the telecommunication and related sectors. For them, the TMForum paves the way for the exploration of new technologies and business models.

One way TMForum does this is through the Catalysts program. The Catalysts are innovation activities by the TMForum. Each Catalyst has a champion (usually one of its member organizations) whose role is to identify a business problem/challenges to be solved and convene a number of technology providers to work on rapid innovation sprints. Innovation sprints span a 12-weeks timeframe and conclude with the presentation of a prototype solution.

The IOTA team participated in the Catalyst focused specifically on exploring the role that blockchain and distributed ledgers will play in creating new markets for Communication Service Providers (CSPs).

In Nice, IOTA demonstrated the DLT-based Telco Asset Marketplace. A new form of decentralized digital marketplace. The presented work was shortlisted for an award.

The problem

So what is the Asset Marketplace presented by IOTA? Before explaining the solution, let’s start with understanding the problem.

There is an axiom that CSPs understand well: An underused asset does not generate enough Return of Investment (ROI) to cover the Capital Expenditures (CAPEX) required to build it. However, an underused asset still requires Operating Expenses (OPEX) to maintain it. So as a result, an asset of this kind generates costs that are not covered by its returns — an unintended problem that investors and asset owners are constantly dealing with.

Although this problem generally applies to various industries, let’s focus on the assets we are talking about in the realm of CSPs. In this case, a few examples can include cell towers, wifi infrastructures, frequency bands, fiber networks, and aerial drones used to bring connectivity in remote/rural areas.

When do these assets become underused? It can happen anytime. Most of the telecommunication networks have overestimated capacity in many urban areas. However, they can also be underestimated in less populated regions or easily fall short of required capacity when special events occur in particular locations and at specific times. Think of large sports events, music concerts and festivals.

You have probably already experienced the frustration of trying to use your mobile phone to upload a picture during a concert or a football match.

However, this under and overcapacity is mostly the result of the network infrastructure being siloed within each CSP domain and used only for its customers without any cross-CSPs customers sharing.

So you can see how an opportunity to offer these assets emerges. If there was a marketplace for them to be displayed and offered to potential buyers.

But is there a demand for these assets? The answer is Yes.

In particular with the advent of 5G networks and service-based architectures, the concept of Infrastructure as a Service (IaaS) will represent a driver for innovation.

In a similar way, Mobile Virtual Network Operators (MVNOs) already need to provision in advance resources for their customers before their actual use. This involves making requests to Mobile Network Operators (MNOs), that own the infrastructure. It is clear how increased flexibility in this process would definitely benefit the market.

Together with new business models, two new types of stakeholders appear. The Asset Providers (Sellers), those CSPs with unused assets, and the Service Providers (Buyers).

But who are these new Service Providers? It can be anybody developing a mobile service. In particular Small and Medium Enterprises that leverage innovative technologies to create services for their customers (B2C) or customers of their customers (B2B2C).

But with Service Providers being mostly SMEs, neither them nor their customers can afford to sustain the capital investment required to deploy the infrastructure hosting their mobile services. This hinders the opportunity to deploy many innovative new solutions.

If demand and offer meet, a new market will flourish

With that, the revenues generated by consumers using these services can help to cover the operational costs and generate a new return of investment for underused assets provided by asset owners. Underused assets would no longer be something that worries CSPs.

Think of the following scenario: a concert organizer wants to provide an immersive experience for its participants, consisting of virtual (VR) and augmented reality (AR) effects accessible through participants’ mobile phones and smart goggles.

The concert organizer requests a pioneering AR/VR SME to develop this service as a mobile app. However, the deployment of this service requires users to access a large mobile Internet bandwidth which is usually not possible in very crowded areas when only a CSP provides it for its customers.

On the other hand, the service provider and the event organizer cannot afford to ad hoc deploy the required infrastructure. But the situation might change if different CSPs can offer unused frequencies, cell towers, aerial drones, and WiFi infrastructures for a limited time irrespective of their customers being in the area or not.

A marketplace where this demand and offer can be matched is still missing.

So how do you develop such a marketplace? In the best scenario, digitization can lead each CSP to build its own marketplace where service providers can search and request needed assets.

However, in this case, the friction generated by the fragmentation of marketplaces will easily overcome their benefits. With asset offers posted on different marketplaces, service providers will need to process results from different platforms. This increases the complexity of the assets discovery.

At the same time, asset payments are done using different systems. With service providers needing to set up and manage different accounts with increased overhead and costs. This is particularly relevant for small service providers. As a result of this fragmentation, the auditors’ job in certifying the compliance of different marketplaces also becomes costly and complex.

Instead of fragmentation, the answer is a marketplace shared among all CSPs but not owned by a single one. This can bring various benefits. Developing a transparent open marketplace with permissionless access, where both asset and service providers post asset offers and requests, and where automated matching and payments settlement with tamper-proof audit trails are provided, will deliver many gains. These include:

  • A real-time offer and request discovery process and optimal asset matching
  • The maximization of ROI for Asset Providers and best asset selection for Service Providers
  • A unique payment system to speed up asset access
  • An easy-to-review audit trail and fast usage agreements clearing for auditors

However, there are also barriers to developing such a multi-sided marketplace. First, the lack of trust and difficult accountability of who offers and who accesses what, under which conditions. Second, the distribution of revenues and tracking of liabilities in case of misuse.

To overcome these barriers we developed the IOTA-powered Telco Asset Marketplace.

Curious to know how we built this marketplace? Why don’t you take a look at the second and more technical part of this blog post?

Sergey Ivancheglo departs from the IOTA Foundation

Sergey Ivancheglo departs from the IOTA Foundation

18:42 - 26/07/2019

Sergey Ivancheglo, better known as Come-from-Beyond/CFB had planned his resignation from the IOTA Foundation when the Alpha and Omega engineering teams were to be merged at the end of June. As planned Sergey submitted his resignation letter on the 26th of June and stepped down from the Board of Directors. Since then he has handed over some backlogged work in the role of an unofficial advisor to the Foundation but holds no position in the organization.

Sergey Ivancheglo on his departure from the IOTA Foundation

I no longer believe that the IOTA Foundation is the best setting for me to realize what we set out to create back in 2014 and 2015. I have always done my best work in a less rigid environment. I am looking forward to continuing the work on both hardware and software development of IOTA independently. Additionally, my use of free speech has repeatedly been leveraged in unfair attacks against the IOTA Foundation, something I am very tired of. I represent myself and only me when I express myself via personal mediums such as Twitter.

As everyone knows, CFB has been and continues to be one of the most prolific and influential people in crypto and has served an absolutely pivotal role in the IOTA project. We fully supported his decision to depart when he revealed his plans to resume working independently to us back in March. The IOTA Foundation is very grateful to Sergey for all his contributions to the Foundation and looks forward to a fruitful collaboration with him in his role as an independent developer.

A personal note from David

Although I don’t always agree or approve of CFB’s unorthodox actions as it pertains to communication, I fully trust him as my co-founder and nothing has changed in terms of the development of the big picture.

This blog post was planned to be released in a couple of weeks, but due to unforeseen events today we chose to make this public today.

What is the IOTA?

If the Aether is turned towards smart contracts, the IOTA (or MIOTA) is linked to connected objects, to the Internet of Things, which some people call “fourth”. industrial Revolution”.

Created in 2015 by David Sonstebo, Sergey Ivancheglo, Dominik Schiener and Dr. Serguei Popov. IOTA is based on a technology that allows free and instant transactions between machines in the Internet of Things environment.

Unlike Bitcoin and most cryptocurrency, IOTA units already exist (2.779.530.283 in total), and the motto is not based on the mining system (creation of units via computers, note).

IOTA also differs from other cryptocurrencies in that it does not rely on the blockchain technology mentioned above. It is based on Tangle technology, fully decentralized, which allows transactions at no cost, secure, and instant.

The applications are numerous. The IOTA allowing micro-transactions since there are no fees, many companies, including small businesses, merchants could be interested. The Tangle technology on which the IOTA is based can also be used to transfer data, can be applied to set up electronic votes, or even serve as a basis for encrypted e-mail.

IOTA could also be set up in the area of ​​the shared economy. We can imagine Paris Vélib ‘working with this technology, but all kinds of connected objects could be shared.

The IOTA has experienced a recent craze its course passing in less than a week of a few cents to more than 3 dollars per unit. This interest is explained by the announcement of a partnership with major companies such as Microsoft, Samsung, Cisco or Volkswagen.
