but you also assume that POW is how currencies should be managed, and as you know there are rivaling strategies.
I don't recall saying that anywhere. EOS has solved the scaling issue better than bitcoin and ethereum, but does sacrifice some security and decentralization to do so. Each blockchain has its different uses.
I did not try to ask about the whole scaling issue.
I only asked about storage of entire histories.
And it may not be only a POW issue, because Byteball has it too.
It might have a good reason that still evades me.
I ask because I want to know if it exists and if it does, then what is it?
Study how the hashes of each block link the blocks together in a chain. This is in Andreas Antonopoulos's book "Mastering Bitcoin" on github. It's not impossible to change these things, but a hard fork would be necessary and that's potentially dangerous to the ecosystem.
Does it apply to Byteball?

I haven't looked at the Byteball code.
