IOTA / Ethereum Summer Camp

Recently, we’ve been working with IOTA’s team by adding their MAM (Masked Authentication Messaging) support to RuuviTag.

This made RuuviTag the first IOTA compatible low-power sensor device available.

To showcase the new feature and to allow developers to use RuuviTags in their IOTA/Ethereum projects as soon as possible, we headed to Frankfurt where a 5-day blockchain/tangle hacking event took place.

The sold out event was organised by Frankfurt Business School Blockchain Center and had a several fascinating speakers.

The week was really productive and inspiring in many ways:

Dozens of talented developers built their real-world IoT business [proof of] business concepts on top of IOTA/Ethereum using Raspberry Pi / HiKey hardware platforms and RuuviTag sensors.

After brainstorming on the first day, teams decided what to build and if they would like to use RuuviTags in their projects.

The teams created in total 15 (!) awesome projects and presented those at the closing event on Friday.

This is one of the projects:

Basics of the project. A RuuviTag on bottom and a Raspberry Pi 3 as a gateway. Could be also a mobile phone.
An encrypted MAM message
An encrypted MAM message sent successfully from RuuviTag to the Raspberry Pi 3. After this, the RPi publishes a transaction to the Tangle.
