IOTA core functions like address generation, signing, “Mini-Pow” and Proof of Work (PoW) need much computational power which makes it almost impossible (in a practical sense) to be done by small embedded systems.

The aim of this project is to develop several modules that can be use by existing or new embedded applications needing IOTA core functionality.

The first is an IOTA Core FPGA module which provides most IOTA core functions with hardware acceleration. It will offer a high-level API which is easy to use whereas computationally intense low-level calculations are off-loaded to specialized logic which gives significant advantage in speed compared to a software-only solution – making it perfect for embedded applications.

Additionally, the FPGA module implements several security mechanisms which will make it very hard for attackers to unauthorizedly gain access of seeds which are stored on the module.

The second module will be a System-on-Module (SoM) which will use the FPGA module. This SoM will have enough resources to use it for a large number of applications. It even could run Linux. The SoM could be seen as an integration example for the FPGA module. It can be used unmodified for own applications but other microcontrollers could be using the FPGA module easily as well.

The third module is an application board using the SoM which will be an IOTA sensor gateway for simple and cheap sensors.
