This is the relevant comparison! In another comment I asserted that I would be surprised if Blockchain doesn't use at least 2 orders of magnitude more energy per transaction than traditional banking.
Seems I was off by about 5 orders of magnitude, in Blockchains favour!
- FabHK 3y agoTraditional banking also does a lot more than what BTC does. BTC is about 9 orders of magnitude less efficient than the effective work it does. Look, you can run a full Bitcoin node on a Macbook that uses 20W. It can easily verify 5 transactions per second, put them into a block, and compute the hash of it, and do some network communications. The actual network uses 20GW, a billion times more energy, because they have thousands of nodes replicate the same work and then add PoW as a cherry on top.
