We are a working group focused on the DLT for IoT, since we are convinced of its potential. We are not experts in this area, but we want to learn and collaborate on interesting ideas, so do not hesitate to contact us if you are also interested in this field 😉

We are open to collaborate with people from all over the world, but for geographical and language reason, we believe that our group may be of more interest for Spanish speakers (all current members are from Spain).

Our current goal is not to make money, but we appreciate any donation to pay hosting, buy some cool gadgets to try new ideas or carry out activities to publicize our group.


We do not expect to receive many donations, but in the ideal case that we receive several donations, we promise to be transparent 😉

Our active members are the following (listed in alphabetical order):

  1. Estrella, Fco Javier
  2. Moya, Francisco
  3. Quesada, Francisco J.

Do you know that IOTA uses Witernitz hash-based cryptography signatures and this implies that an IOTA address should not be reused for payments?

MAIA is the acronym of Masked Authenticated IOTA Address. It is a public MAM channel in which each message is an IOTA address and which always returns the last message. What is this for? To provide a way to always obtain your valid IOTA address.

Kiri allows you to running a private IOTA testnet in a low cost single board computers. It is based on https://github.com/schierlm/private-iota-testnet.

Its main advantages are that:

  1. It is an application for Kura (easy to install and manage).
  2. It works in ARM architectures (it uses a fork of RocksDB).
