IoT is growing with around 50bn IoT devices forecast by 2025. At the same time, other developments like Autonomous Cars, Smart Cities, 5G, AI, and Blockchain are shaping a new dynamic of interoperability and integration. All of which is driving the transition to the internet of value. Vodafone partners with businesses of every size and are embracing positive change through digital communications technologies. They are working with the world's largest multinational companies, fast-growing enterprises, Government teams, ambitious start-ups, and small businesses across the globe. However, Vodafone is much more than mobile, fixed, and unified communications. The company isdeveloping the capability to leverage their IoT SIM to generate PKI and also incorporate a SIM wallet to equip IoT devices to be part of the economy of things. I wanted to learn more about how it will provide the capability to transact peer to peer and how the blockchain also acts as a trust anchor/ledger for IoT device interoperability (Security and Authentication). Smart Cities/Smart Citizens are also developing to act as a service provider for things, and a possible purchaser of data generated by IoT devices. Recent developments in Smart Buildings and IoT Payments also show how Vodafone is approaching these challenges. After seeing David Palmer talk about Blockchain, IoT, and 5G for Vodafone Business, I invited him on to Tech Talks Daily to talk about what it all means for technology communications and enterprises.
