Last year MWC was the time of minimum knowledge and maximum hype for blockchain. Now we have much less hype, but there are also much more real uses for blockchain. Edge has had much less general hype, rather it has been telco hype. But actually Edge and blockchain together can be components for true significant changes in internet services; to the point where the internet is not same anymore.
For example, last year I was listening to a middle Asian telco describing a strategy to conduct bitcoin mining, because they have cheap electricity.
