I fail to see how "Witnesses power the blockchain". From my gathering most witnesses are a net drain on it, especially with most of them running some form of bot and making bank due to that.

Or is this due to your other comment in regards to the common misconception that witnesses were the ones running the IPFS nodes and not just the average everyday joe blow with no power at all?

(I run an IPFS node and I'm a plankton)
