We are living in first person the Digital Revolution and broadband connectivity and telco networks are at the heart of this Revolution. We are building the networks for the future and connectivity is crucial for new applications like AI or autonomous cars. The future travels through our networks, and the networks can give an additional layer of trust to the operations. We don’t say security, we don’t say reliability, we don’t say privacy. We say TRUST. Nobody has to validate, certificate or audit what’s happening in the network, the network itself will do it through a blockchain layer.

The starting point
What we are supposed to do
Industry analyst and consulting firms
released from 2015 on a lot of reports
listing use cases for telcos. Most of them
include Fraud prevention, Identity and
Data management, new networks and
IoT devices deployment and security,
clearing and settlement, roaming
management, number portability, etc.
https://jln.bz/30OVAkl
https://jln.bz/30OXEbP
The GSMA also released a document of
opportunities for telcos that also
included cases such as content
aggregation & delivery, wallet services,
mobile money, P2P Networking,
decentralized compute services &
storage, OSS & BSS efficiencies,
tokenization and trading of digital
assets, etc.
Consortiums appear as the most extended option to
address blockchain projects, following a use-case-guided
development or generic approaches to technology
Hyperledger
Telecom SIG
Vendors and startups are also very active proposing telcos
pilots and PoCs to create a new and vibrant blockchain-
based telecom ecosystem

3. The opportunities
What people wanted us to do

4. 44
What’s next?
We need a framework to choose among the opportunities
… but we have to really understand
the benefits and assess REAL
opportunities to decide how to
implement Blockchain across the
organization to solve specific
problems better than using other
alternatives
Do I need a
blockchain?
NO

What we learnt
Beyond the impact, we found some key learnings
FRAGMENTATION
A unique and global reliable
blockchain network is not needed
anymore
REPLICABILITY
Most of use cases get the
same benefits from
technology: data saved
immutability and consensus
GIVE ME THE CASE
People want a solution that
addresses their pains and they don’t
care about underlying technology,
consensus mechanisms, consortia or
architecure

7. Blockchain adds a trust
layer to the operations

Our vision
We understand the main benefit to adopt Blockchain

8. Our big bet: Telefónica TrustOS
Transfering the TRUST proposition to the network
A kind of decentralized kernel or middleware including modules and APIs to
transparently manage, track and settle cryptoassets and decentralized
identities that seamless flow and interact with existing platforms and current
blockchain networks and ecosystems.
