scope:

The present document defines a RA for a Permissioned Distributed Ledger platform [i.1]. The present document also describes the characteristics and behaviour of this platform, along with the services that it provides and exemplary solutions that can be built using it.

The objectives of the present document are to:

• Maximize the choice of technology solutions available to entities using ETSI endorsed PDL platforms.

• Maximize ETSI endorsed PDL platforms' scalability in terms of the applications supported and the number of entities able to use them.

In scope:

• Definition of Functionalities, Interfaces, Reference points (e.g. Identity Services: PDL identity, Node identity, User identity).

Out of scope:

• Specific implementation details (e.g. Implementation of identity using a specific method). Such implementation details may be added at a later phase as separate documents or as corollaries/annexes to future releases of the present document.

The approach taken in the present document is to focus on defining what needs to happen, not how it is implemented.
