For the IoT you might want to check out this thread. As @bochaco points out:
… there are several frameworks and protocols out there (e.g. MQTT and CoAP) but they are all pretty much having similar issues, and their challenge seems to be mainly related to security and NAT (to connect to the devices in different networks). Then I found out that the way they all seem to solve it is by having servers/brokers in the network, which not just adds complexity to the development of the devices’ software, but it also brings in security concerns about who you are sharing the information with when your IoT things need to communicate using these servers, you are forced again to trust third parties.
Now, it’s obviously early days but in theory SAFE could solve many of these issues.
Security is probably the benefit of SAFE that’s easiest to understand and promote, namely:
- All data on the network is encrypted
- Possibilities of DDoS are hugely reduced
- Resilience of the decentralised architecture - should be pretty much impossible to take it down.
Then there’s performance. Unlike the current internet, the more machines that are connected the faster it will be, and the more popular a certain file, the quicker it will download.
The proof of the pudding will be in the eating of course, but that should whet their appetites.
Blockchain enthusiasts should be interested in the potential for a consensus model that does not require proof of work and is much more scalable. XOR networking is well explained here. Meanwhile if they are interested in the difference between BTC and Safecoin they could look here.
