I was thinking about on boarding investors, on boarding clients, generating reports for this investors, collecting payments, etc. I think the meter data is of the least importance here. I've worked with huge amounts of remote metering applications that have significantly more dollars at stake. The industries that use them already have standards in place for how to deal with measurement problems.

If you are right then I'd hope you'd start an efficiency as a service company that covers upgrade costs up front and collects payments over time. There is a huge lack of providers in the space that are a few thousand dollar or less upgrades with payouts over about two years. You can see the challenge, you have to spend less than a few hundred dollars in overhead/transactions over a multi year relationship!

The vast majority of companies in this space are targeting large facilities with multi million dollar upgrades, because it is hard to make the numbers work otherwise.

I concur with your point, considering we already have methods like hashing to create rather unique signatures, and with frameworks and regulations(laws). I'm going to vaguely quote James Mickens here, but you can basically sue someone if there is an issue. If there is an issue on the block chain? You need to fork it. Oh, and the talk for anyone who's interested considering he conveys a few interesting points I've seen throughout this thread. https://youtu.be/15RTC22Z2xI

You can always write 'correction meter reading should have been ...' on the chain.
