But I don't see why there is the need for hostility.
Because you're being disingenuous. Despite having this pointed out multiple times in countless threads you are still propagating falsehoods.
"Bitcoin can not scale to high transaction rates on affordable hardware" is false.
"Bitcoin requires improvements to the way it stores and broadcasts blocks in order to scale to high transaction rates on affordable hardware" is true.
And in what way should that be possible?
Please give concrete suggestions.
edit: I've logged just 7 hours so far reading this forum so it's likely I haven't seen the posts in which it is explained how you can make Bitcoin scale to 1000+ transactions/s, so please be a bit patient with me if I don't know the suggested ideas already.
the simplest explanation i am aware of is two fold: one, altering the blocksize limit so allow more then 7 transactions a second at maximum. whether this is done, how it is done, when it is done, is a major discussion point.
of course, in addition to allowing more transactions, we need a way to handle the ever increasing size of the blockchain. this is where pruning comes in. i'm not totally familiar with the technical aspects of it, but it basically boils down to not needing to keep of record of transactions that have been entirely spent in the past. if/when implemented, this will dramatically reduce the size of the stored blockchain. combined with "light" clients that don't store it, like web wallets and such, that should resolve this particular issue.
