You still don't understand what I'm talking about. If you just attached some transactions to your block without securing them then no one cares about them. Realying nodes may change them while relaying and next miner can just ignore them and add there any transactions he wants.
Sure. And? Transactions would be malleable and not considered confirmed
at all until N confirmations. Each additional N confirmations would offer what is currently 1 block worth of added integrity. An N block fork would then be equivalent to what a 1 block fork is currently, and N block forks would become as common as 1 block forks are currently. Other than "scaling the security factor down by N" what is the problem?
Centralized banking system is also difficult to attack by anyone "not them". But the whole point of cryptocurrencies is that no one should have any large control.
Yup... right now we botters are the ECB of the moto. However, my point is that if 1000 people fire up bots it will add *far* more security to the network than if 1000 people human-mined.... in the same way that the first people to run asic on BTC basically owned the BTC chain for awhile, but now the btc chain confirmations have what you might call "ridiculously high integrity" because of those asics. (compared to the integrity afforded by CPU/GPU miners.) Sure, they consolidated and centralized things more than we probably would've liked, but the network as a whole is
much stronger for it, now.
Yes, I didn't thought about it, this makes it almost useless as protection from bots.
Yes, and I think this applies generally to anything that is "added work" to the run calculation. Adding work to map generation (like requiring 100 rounds of sha instead of 1 for each seed point, for example) "works" in some sense, but is mitigated by the early bailout factor that I mentioned earlier. (I'm still not sure if this early bailout is avoidable either, at least not without a very significant change anyway.)
It is a very tough nut to crack, but I'm confident that between us we can find a good approach!
