IEEE had a working group on this but I hadn't seen any actually shipping chips that mortals could get their hands on.
(Edit: Apparently still vapor. Still can't find a source for the Marvell 88Q1010 & 88Q2112.)
(Edit: Only thing available seems to be this which is almost certainly some gigantic FPGA solution ... https://beyondstandards.ieee.org/connected-vehicles/intrepid...)
10Base-T1 might be a real thing someday. You might just want RS-485.
Each subscriber had their own batteries (No. 6 cells), so there was no DC on the line.
There was Ring Current of course, but that has always been well above 50 Volts.

Now you are more likely to get the minimum speed this way (1MB?) than the GB stuff some of us have come accustomed too.
Yet in 2017 we still have only 1Gbit Ethernet in LANs :(
1Gbps = 125 MB/s !!
I am running 1Gbit since 2003 at home. And all f..king home network devices still support only 1Gbit Ethernet. It's not fast enough. When can some network company finally release 10Gbit or 100Gbit Ethernet (copper or fiber) for cheap home usage.
My home network still runs on 100MBit, because of a stubborn old switch that refuses to die. By now, my curiosity to see how long this thing will last (it is about 13.5 years old) outweighs my impatience when pushing large files around. ;-)
So yes, they probably violate the GPL.
Blockchain networks have no capability of this concept
Otherwise: Dabnabbit Maude, the cows gone loose again because we lost the interwebs. (I’m half-Texan so it’s not -ist.)
Perhaps not "the internet released the cows", but at least "the stampede cut the phone lines".
Seriously, this reminds me about the stories I read on HN about how early telephone networks were established by farmers (ab)using their electric fencing for communication.
