This kind of shit makes me just not want to post at all.  No it isn't an admission like that.  All security models involve assumptions.  The assumption for Bitcoin is that the attacker will not gain 51% of the network hashrate and that gaining that would be prohibitively expensive.   You will notice the words "I believe", it isn't "I know".  An alternate security model will be a tradeoff.  There is no guarantee the modified assumptions will make the network more secure.  Security is ALWAYS about compromise.  The system which is most secure from an attacker with significant resources would be where an absolute central authority that manages the network.  No 51% is possible but you now need absolute trust in the central authority.  Although it solves one problem it creates another and I wouldn't consider that an acceptable tradeoff.

Do you get tired of being a shill?  Don't you ever just want to think and discuss?  Why not just read the post and agree or disagree without looking for some angle?  Don't you find it tedious and small?  At one time this forum (especially this section) was a place to learn, think and explore.  I guess that is dead now.  Honestly I don't give a shit anymore.  This will be my last post.
