I had not heard about the Sovrin Foundation initiative, thanks for pointing it out. The fascinating thing about Blockchain is that the power of connectivity comes naturally to us "Netheads". Beyond the hashtags and the Byzantine General's problem - Blockchain takes the concept of universal connectivity to a new level. It's unversal. It's untrusted. And yet immutable and secure. Hence I'll make sure to follow Cisco's Blockchain involvement closely. There's something aout Blockchain that is inherently tied to network technology.
