Introduction and context

6.
The European Union's main aim is to promote
peace, its value and the well-being of its
people in an area of freedom, security and
justice without internal frontiers, in which the
free movement of persons is ensured in
conjunction with appropriate measures with
respect to external border controls, asylum,
immigration, and the prevention and combating
of crime. In its relations with the wider world, the
Union shall uphold and promote its values
and interests and contribute to the
protection of its citizens.

What is EBSI?
The European Blockchain Services Infrastructure (EBSI) aims to become a “gold
standard” digital infrastructure to support the launch and operation of EU-wide
cross-border public services leveraged by blockchain technology.
EBSI aims to establish itself in ‘virtually’ every public sector domain that can
benefit from blockchain technology. EBSI will focus on specific use cases where
blockchain technology can enhance cross-border digital public services.
These use cases are identified and selected each year by the Member States
(European Blockchain Partnership) and the European Commission.

Problems we want to solve
with ESSIF
● Data acquisition and maintenance
● Data processing
● Data silos
● Lack of data control
● Privacy issues
● Lack of universality
● Lack of interoperability
● Limitations of eIDAS
● Lack of certifications

23.
● How to facilitate cross-border interaction with SSI.
● How to make/keep national SSI projects interoperable.
● How to integrate/align existing building blocks such as eIDAS,
e-delivery, once-only with SSI.
● Stimulate the SSI-transformation of public services
● How to conceptualize and build an identity layer in the new European
Blockchain Services Infrastructure.
● How to preserve European/democratic values in the implementation of
Self Sovereign identity.
● Stimulate SSI development and standardisation on global level.
Scope ESSIF
ssimeetup.org · CC BY-SA 4.0 International

24.
Out of scope of ESSIF
● The interpretations of the data (semantics) and the necessary
standardizations and business logic is however outside the scope of ESSIF.
● ESSIF will provide in its first instance support for other EBSI use cases (like
diploma and notarization)
● The issue of consent is partially implicit and for the other part out of scope.
● ESSIF will not build and maintain an SSI wallet for all European citizens and
interfere in this way with the emerging market of SSI solutions and personal
data storage.
● Academic research on SSI is out of scope of the EBSI use case ESSIF.
● Measures to cope with the dark side of SSI are out of scope but need to be
subject of further academic research.
