You missed a factor of 1,000. 100 bytes * 1B = 100GB/day. You Still got the 36TB/year part right though. Another thing to keep in mind is 100GB/day / (86400s/d

You missed a factor of 1,000. 100 bytes * 1B = 100GB/day. You Still got the 36TB/year part right though. Another thing to keep in mind is 100GB/day / (86400s/day) = 9.2MB/sec ~= 90Mbit/sec Internet connection. That's not a small potatoes connection...

Yea, noticed the typo. Anyway, you can get 1,000Mbit connections in much of the world for under 100$ per month which should be able to handle a full node. Also, most people don't need to actually run a full node to be a miner. Assuming you trust someone running a full node and the block is signed by hash of hash of (node + random value ) < some value then most miners need only get that initial hash from the trusted party which is under 1kb. You can also send back the best hashes you find to the full node to demonstrate you actually have that hashing power. It's appealing to have a lot of full nodes backing things up, but in practical terms I don't think it makes much difference if there is 1,000 or 100,000 full nodes. The important bit is for anyone to be able to trust the network not just to waste as much computing power as possible. And for that you can verify some random collection of transactions with less than full bandwidth which lets you verify the full node you're supporting. PS: You could also set things up with shards, but again I don't feel it's nessisarily worth it.

  Where do you live? In the US, Canada, Australia, many African countries you aren't getting 1Gbit fiber for under $100!

    Don't need home internet connection that fast. Just rent a server at a datacenter near an internet exchange point, and could get plenty fast bandwidth.

    Google fiber charges 70$ a month for Gigabit network speeds without throttling in the USA. And get this it's profitable for them without subsidizing it. https://fiber.google.com/cities/atlanta/ https://fiber.google.com/cities/atlanta/
