The document discusses potential applications of blockchain technology in the telecommunications industry. It begins with an introduction to blockchain and why it is relevant. The agenda then outlines discussing known facts about blockchain, market growth predictions, fantasy projects that cannot be started in 12 months, immediate opportunities, and a case study on a peer-to-peer telecom exchange. Specific applications mentioned include interconnect/roaming, supply chain management, IoT provisioning and control, and enabling 5G/global service delivery. The case study focuses on using blockchain and ENUM for a P2P voice call exchange accessible to both operators and individuals. Challenges mentioned include rapid technology evolution, data privacy issues, and authentication gateways.

with various degrees of
trust

11. 'Traditional' VoIP
exchanges
● Multiple independent
authenticators
● Each participant
contributes processing
nodes
● Transparent for end user
● Central data authority
● Added operational
costs
● Poor UX for end user
Blockchain-based

12. Challenges
