Streams is a level 2 cryptographic framework to send data over the IOTA Tangle. We developed a generic gateway to allow different devices using the I2T Standard, to publish their data on Streams in an easy fashion.

To this end, our I2T Gateway listens for data sent via POST requests and sends it to the Tangle via Streams. On the other end, we have provided a I2T Decoder, allowing for subscriptions to existing channels carrying information.

Streams acts as your immutable data storage, distributing the information amongst the network nodes. …

1. About the “Integrate Everything with IOTA” Hackathon

After releasing our I2T Open-Source Hub featuring integrations between a number of IoT devices and the IOTA Protocol, IOT2TANGLE is calling for community IoT/IOTA submissions for the “Integrate Everything with IOTA” Hackathon, sponsored by Espressif, STMicroelectronics, Bosch Connected Devices and Solutions, Senseering, Vass Company, IOT ONE Academy and the IOTA Foundation.

This Hackathon aims to generate quality open-source integrations that will be valuable stepping-stones for subsequent development projects that connect IOT devices with Distributed Ledger Technologies. Before you keep reading, we invite you to join the I2T Discord Server to learn more about I2T.

After almost a year, a lot of research and testing different IoT devices we are now live! In this short post we will be introducing the I2T Hub, explain how it works and what we envision for the future.

As you might know, IOT2TANGLE is a project we envisioned while working with XDK2MAM. Back then, we understood that providing an easy to run open source codebase together with clear step by step instructions was a big enabler for those trying to validate simple IoT concepts: plug the XDK110, follow our steps, start retrieving measures and send them to the Tangle.

It didn’t take us long to realize that if we could provide the same solutions for multiple devices being used by IoT developers, we would simplify and speed up the roll out of projects based on these solutions.


As we are nearing the end of the XDK2MAM roadmap, we still have a hard challenge to solve: make the XDK110 send MAM messages onboard. To tackle this endeavor, we have chosen to work with MAM2, because it has a C implementation on Entangled. But things are not easy at all: C based MAM2 is still under development and the Build system used by IF (Bazel) does not help a lot when trying to compile the needed code on devices such as the XDK110.

Since our last milestone overlaps with IOT2TANGLE (our new proposal to extend IoT-Tangle integration) we thought it would be a good idea to start by transitioning from Bazel to a more IoT friendly building tool. Considering that some work had already been done on the Entangled cclient by Sam Chen using Cmake on an ESP32, we decided that this was the right tool. …

After almost a year working on open source code to integrate the Bosch XDK110 sensor’s node with IOTA, we are now introducing a broader project involving integration of the most used IoT boards to prototyping or even for production.

Some months ago we released a post in IOTA Hispano. Back there, we already knew that to integrate this useful tool to prototype IoT was only the beggining of a wider roadmap. As that post, written on December 2018, states:

Yes, our roadmap is about the Bosch XDK110-Tangle integration, but there are too many devices out there and we are confident that we will be able to start working on solutions to integrate some of them as well. As we develop our XDK110 based roadmap, we aim to slowly build an open source Hub that will allow the community to start connecting devices to the Tangle. …


Long time no see right? We are happy to announce that XDK2MAM Phase 1 compromised to the EDF is now finished. This last six months were really exciting as we combined the development of various open source packages to connect the Bosch XDK110 sensors node with the Tangle and traveled as much as we could to conduct “hands on” Workshops and introduce IOTA’s Ledger and Masked Authenticated Messaging as a solution to decentralize information produced by this great device.

We dictated workshops in several cities of Argentina, Uruguay, Brazil and Venezuela and there is more coming! Our next workshop will be conducted in Berlin! Yes, XDK2MAM is visiting Germany and we already have plans to meet the guys behind the XDK110 at Reutlingen, Daniel Trauth and his amazing IILA and, of course, people interested on IOTA in Berlin, home of the IF. …


Origin, a quick review

We started working on XDK2MAM by Q3 of 2018 as an attempt to integrate the Bosch Connectivity XDK 110 with the Tangle, providing this great IoT prototyping tool with the capability to decentralize sensor’s data using Masked Authenticated Messaging.

Because we quickly understood the importance of a tool of this kind and found out that there was no code available to use it together with IOTA, we decided to request funding to IOTA Ecosystem.

Our mission was clear: build the bridges between this particular device and IOTA, providing open source code, guides and tutorials to help interconnecting the XDK110 and the Tangle. …

The Meetup

Daniel De Michele (Carpincho) and Alejandro Elustondo from XDK2MAM introduced IOTA in the Cardano/IOTA/EOS/Monero Meetup hosted by the NGO Bitcoin Argentina this past Friday 24th August.

The NGO Bitcoin Argentina is working with DLTs since 2013 and this invitation was a great oportunity to introduce IOTA to a blockchain-minded audience and to share space with other DLTs such as Monero, EOS and Cardano.

The goal was to introduce the Tangle as a new and revolutionary data structure, the proposed consensus model and to show the work being done by XDK2MAM to decentralize Bosch XDK 110 sensor’s data via Masked Authenticated Messaging (MAM). …
