Distributed Ledger Technology


The objective of the ATIS DLT project is to validate key aspects of distributed ledger technology as it applies to real-world challenges facing today’s communications industry. Through the analysis of a specific use case, it will assess if the unique characteristics of DLT can be a game-changer by enabling innovative solutions to difficult problems.

The basic idea behind the use case the focus group has identified is to study how we can combine data about outgoing calls (origination, end customer, call purpose, etc.) leveraging a distributed ledger so that the terminating service provider (and their analytics/call-blocking service) can provide a better mechanism to differentiate between good and bad calls. This is especially difficult – and valuable – in complex calling scenarios where, for example, a call center may be originating calls on behalf of an enterprise, using 3rd party calling platforms, and multiple originating service providers, for a short-term calling campaign such as a product recall. This very realistic scenario isn’t adequately addressed by SHAKEN, but it can leverage capabilities that are provided by SHAKEN. Therefore, the analysis will build on the STIR/SHAKEN mechanism that provides verified information about the calling party number as well as the origin of the call — known as “attestation.” It will combine SHAKEN with information about the call origination and use DLT to allow a range of players to access the information they need for their role while protecting the information from unauthorized access – something that is central to DLT.

The following FAQ provides answers to key questions about the definition of SHAKEN and how it relates to this DLT project.
