What does blockchain mean for OCF? It's hard for me to see a near-term synergy. OCF tries fairly hard to be stateless, at least in terms of protocol (RESTful); security setup is at least partly a different story. Blockchain, on the other hand, is about as stateful an application as you can imgine: not just is current state crucial, but as a ledger, historical state and the immuability thereof is also important, bringing with it the possibility of lots of storage requirements, which in turn implies the network probably needs some kind of master ledger nodes so small-footprint nodes don't have to keep local copies. I know there's a lot of smoke coming from this direction, and one assumes there must be some fire behind it, but I'm not seeing it. I presume there are people much smarter than me with ideas.... That's pretty much where I am. I cannot (yet) see how you can have both ultra-constrained nodes and blockchain, but that's prolly cause I'm not smart enough. The one use case I can see is audit trail, keeping a record of on/off-boarding, config changes, OTA updates, etc. Afaik OCF does not directly support that so you would have to build an upper level to do it anyway. I can almost imagine BC doing that. G
