Definition

The present document defines a RA for a Permissioned Distributed Ledger platform. Following the terminology and general architectural requirements, the present document discusses the architectural components listed below:

a) Orchestration, governance, process management, and eco-system coordination in a complex environment (for example node and PDL management in an environment involving multiple competing parties or supply chains).

b) External and internal information exchange (for example through Oracles, APIs, micro services, webhooks, or external data sources).

c) Off-chain Storage (another chain, local/cloud node that is not part of the PDL, PDL node but not sharing with other nodes of said PDL, trusted by a single node or trusted by all nodes based on governance, etc.).

d) Smart Contracts (including commonalities between Smart Contracts, interoperability of Smart Contracts across chains, PDL agnosticism).

In scope

a) Definition of functionalities, interfaces, reference points (for example Identity services such as PDL identity, Node identity, and User identity).

b) Functional capabilities of commercial applications using PDL to create/trade value (for example wholesale settlement, cryptocurrency or stable coins-based payments, tokenization, and asset/inventory management).

c) Non-functional capabilities of commercial applications using PDL to create/trade value (for example network design, security, privacy, and access control).

d) Capabilities of different PDL protocols (common aspects of PDL protocols that can be use case, platform, application, and service agnostic amplified through inter-ledger interoperability).

Out of scope

a) Architecture design and implementation details.

b) PDL network design and implementation details.

c) Design and implementation details of platforms built on PDL network.

d) Specific application/ service implementation details of application platforms built on PDL network (for example implementation of identity using a specific method).

NOTE: Any platform, application, or network specific implementation details will be added at a later phase through dedicated ETSI-ISG-PDL PRD documents (Including Functional, Privacy and Security related services and requirements) or an annex to the present document (for other services) on need basis.
