What we do at Alastria


At Alastria we energise and strengthen a multi-sector ecosystem that generates and shares knowledge, with a spirit of collaboration and a common interest: the development of blockchain technology. Alastria acts as a hub, connecting stakeholders and opening up spaces for using and co-creating platforms, resources, standards and guidelines related to distributed ledger technologies.

We are a diverse, inclusive organisation made up of large, small and medium-sized enterprises and start-ups, as well as public institutions, associations, foundations and universities, both in Spain and abroad. This helps us to work impartially, speed up innovation and pool our efforts to meet the challenges of implementing blockchain across different markets.

Our networks

One of Alastria’s missions is to spread knowledge about distributed ledger technologies in a completely agnostic way, as we do not entrust all developments to a single platform. Therefore, our members work and experiment on different technologies to meet their needs and to keep us at the cutting edge of technological progress. Alastria facilitates the framework for the construction of blockchain networks by ecosystem members, who work together to design, deploy, operate and maintain the infrastructure.

  • A public-permissioned platform.
  • Our blockchain networks are general purpose, regulation-aligned and designed to support use cases from multiple industries.
  • PoA consensus model
  • Different technologies to address members’ needs and to be at the forefront of technological evolution.

T Network

This is the network based on Quorum technology. It is a robust, stable and highly resilient network. The digital identity model Alastria_ID is deployed on this network. .

B Network

This network is based on Hyperledger Besu technology. It is a modern, powerful network with the same technology used by the European EBSI network and the Latin American LACChain network. The digital identity model Alastria_ID is deployed on this network.

Digital Identity

Alastria_ID is a digital identity model proposed by the consortium for use in digital services and is inspired by the concept of self-sovereign identity (SSI). The aim is to provide a digital identity that anyone can use for all kinds of online transactions, from renting a bicycle to paying taxes or opening a bank account, easily, securely and with control over their data. It is also applicable to any other use case.

Alastria_ID is deployed as one of the core applications of the blockchain infrastructure and is based on the ten key SSI principles, which are grouped into three pillars: security, controllability and portability.
It is an open source model built collaboratively by the members of the consortium, undergoing continuous revision and testing to bolster security and privacy, and complying with Spanish and European regulations.
The MVP 2.0 version of Alastria_ID  is currently available to all members, as is a set of how-to documents in Alastria’s Git repository.

Presentation of the Alastria_ID model

The SSI model allows each person to manage their own data (credentials) securely, reliably and transparently through their devices (mobile phone, computer, etc.). This way, users can control who they share their data with and access any service.

Alastria_ID uses smart contracts and software components that allow integration with the backend of other services. All this is done through a protocol defined as part of the model and a basic app (wallet) that evolves and adapts to the requirements of users and providers in different use cases.

Using their wallet app, users have full control over what data they have shared, with whom and for how long, as well as the possibility to easily exercise their GDPR rights (e.g. consent withdrawal or data erasure) with a simple click.

Alastria_ID has become a benchmark in Spain and Europe. It has served as the basis for the publication of “Standard UNE 71307-1. Digital Enabling Technologies. Decentralised Identity Management Model based on Blockchain and other Distributed Ledgers Technologies. Part 1: Reference Framework”. This is the first global standard concerning decentralised digital identity management based on blockchain and DLT.

After its publication in UNE, the standard was submitted to the European body CEN/CENELEC for the drafting of a European technical specification on decentralised digital identity, based on the UNE 71307-1:2020 standard, which includes the Alastria_ID model.

In addition, the Alastria_ID model has been included as an example to follow in various documents produced by other international standardisation bodies, including ISO and ITU.


The Funding Desk provides an advice and support service to members, helping them connect with both public funding (EU Next Generation, REACT-EU, PERTES, etc.) and private funds (venture capital, partnership, debt funds, etc.).
For public calls and grants, the Funding Desk gathers, evaluates and supports proposals submitted by members which may be eligible to receive funding from the public body in question.

When the characteristics of a project make it ineligible for public calls, we find opportunities for connection with venture capitalists and other private sources of funding.
The Funding Desk has a team of experts with proven experience in project appraisal, as well as specialised consultancy firms (ecosystem members) that provide technical secretariat services to promote and support projects.
