That's good. It can be hard to find source materials, though I know they're all somewhere. What I've been trying to figure out lately is the real energy cost of the Steem blockchain. I feel like my father and mother would love it here. They, like many on here, are permaculture enthusiasts. But that's precisely why they are resistant. They worry that the energy cost of maintaining the blockchain, like it's been reported about the Bitcoin chain, is excessive inefficient use of power. I think and hope they're wrong, but there are 14k+witnesses, and multiply that by however much energy each witness machine uses, and you've got a lot. And considering how relatively few accounts that's supporting (1 million-ish, fewer active accounts) and it does look like, even though it could be fairly efficient if we only used the 21 minimum machines needed, it won't be until there are many more users than witnesses/wannabe witnesses.
