About

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 😉

Projects

MAIA

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 based in public MAM channels and always returns the last message.

Starting with version 3, MAIA allows you to define arbitrary fields such as a public IOTA address, an email address or a version of a file. You have control over which fields to create.

MAIA implements a data structure designed to optimize efficiency. Therefore, the first updates will be slower, but do not despair, it’s just an illusion 😉

MAIA also allows you to define views, which are transactions that index the field of a MAIA address.

KIRI

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).

Deltangle

With deltangle you can do three things:

  1. Store a text file. You will get a unique hash that will allow anyone to download the file.
  2. Update a text file. You will get a unique hash that will allow anyone to download the new version.
  3. Control the published version of a text file. You will get a unique hash that will allow anyone to download the version of the file that you want.

Deltangle updates files by storing the difference in a new bundle, so it minimizes the number of transactions required to be stored.

In addition, it uses MAIA, which allows you to create a unique address for an updatable text file.

Do you want to try it? Do it here.
