I am always ready to learn, and quite happy to concede when I am wrong about something.
Strange - but although you are ignorant and keep posting rubbish you haven't conceded a single thing - yet keep trying to attack me with your stupid nonsensical posts.
If you aren't @franky1's alt then you ought to team up with him as between the two of you perhaps you might almost have a quarter of a brain.
Unfortunately it is pointless to try and explain SPV mining to someone as dense as you as you simply can't grasp it (no matter how many times it is explained to you).
Perhaps try hiring a "brain coach" or the like?
(some people might even coach you out of pity for free - but that ain't me as I have a rather low tolerance of morons)
Yes, I haven't conceded that I am wrong because you said:
You only broadcast that to your miners (if you are a pool) not to everyone else (you do know how this stuff works or don't you?).
Which is contradicted by evidence that I have posted (rubbish you called it) that suggests this is not true.
I am open minded enough to accept that I have misunderstood something. That every source I have was equally mistaken. That the evidence I have provided I have misinterpreted. (There is a chance BW.COM actually had the full block 401302, but just decided to mine an empty block, for example)
I'm wide open to be proven wrong, and I am more than happy to concede that you were correct about block headers only being sent to miners within your pool (though this does sound a bit like some kind of block withholding attack).
Given the whole premise of your argument about 64MB blocks is based on what *appears to be* flawed understanding, I think its fairly important to establish just exactly how SPV mining works in this regard, so that others that may read this thread don't make the same mistakes as I may have done.
