Motivation
 Telcos are lagging behind Global Web Players but Users (as well as Regulators) are not
comfortable with Web Monopolies gaining more and more power.
 Emerging technologies enable new service delivery paradigms: it is the right time to
rethink communications and disrupt web players.

Design Principles: Decentralised Communications
• trustworthy communication among any peer without central authorities or communication
monopolies.
•inter-operability among Communication Service Providers as well as among Application
Service Providers.
• can be applied to any kind of communication, including human-to-human, human-to-
things, and things-to-things communication.

Proposition1: Interoperability with nearly Zero Standards
Interoperability without having to agree in advance
on common protocols or service APIs i.e. federation
of CSPs is not required.
(Protocol on-the-fly and Reporter-Observer peer-to-
peer data synchronization pattern)

Proposition 2: Power back to People
Users have the choice to decide who manages their private data and identities. The end-
user is empowered to decide about which Identity Provider to trust, i.e. User Identities are
decoupled from Service Providers.

Proposition 3: Hyperties, the reusable building block to
develop complex decentralized Applications
The reTHINK Framework enables the usage of microservices architectural patterns in the
Decentralized Ecosystem.
Hyperties are independently deployable components each one providing a small set of
business capabilities, using the smart endpoints and dumb pipes philosophy.

reTHINK Case Study: Digital Social Market (DSM)
 Exchange of goods and services
 Unites citizens through common
causes
 Work for a purpose e.g. Schools
 Sharing Lisboa Trial: Students,
teachers, parents, local citizens,
local business – community
• 3 Schools
• 4500 students
• 3 neighbourhoods (around 130 000
people)
• Local shops network

Conclusions
• Decentralised Communications are a big opportunity for Telcos to differentiate from
Global Web Players.
• This is a long term journey. Business cases (and models) are a challenge.
•Difficult to get internal support based on services where revenues are eroding (e.g. H2H
communication). Look where your board is investing on.
• Smart Cities fits well:
• Citizen privacy concerns (hello GDPR)
• Heteregeneous (technical and business) environment
• Budget available
• Next: decentralised economic incentives. However Blockchain is still a big “?” (the
revolution will not be tokenised?)
