SPV mining *is not proper mining*.

Is that not clear to you?

It is irrelevant whether or not they use the SPV protocol to do that so (and in fact they don't as they use the "relay network" which existed a long time before SPV support was added to Bitcoin) so your desperate attempts at trying to discredit me are failing and just making you look even more stupid.

If you mine that way then you end up on a fork (as has already happened) and as I have already tried to explain (but seemingly you are incapable of understanding) the larger you make the blocks then the easier it would be to trick other miners into mining on such forks.

And btw - the only *flawed understanding* here is your own.

You are way off topic. Lets zoom back out again.

At the start of this discussion, you made an assertion that a 64MB block takes a long time to validate, and that such a block could be crafted by a miner in order to "own" the bitcoin network. Specifically that this miner could "get all the fees and block rewards".

I asked three questions, the first was the most important. The answer you gave implied that you thought block validation time was the key to the malicious actor owning the network.

You had not stated this explicitly so to clarify, I asserted that the validation time of a block has no bearing on whether other miners can start mining the next block, as they can mine knowing just the block header.

I labelled this as being "SPV mining" (but as you rightly point out in your previous post could have been obtained through the Relay Network). The salient point was that any miner has the potential to mine the next block, because they have the block header and did not need to have (yet) validated the full block.

However you refuted this, stating that "everyone else" (other miners) would not know the header, because the header was only broadcast to "your miners (if you are a pool)":

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?).

Your original premise that the block chain can be owned by crafting a expensive to validate block, relies upon miners having to validate the block before they can start mining relies on your refutation.

There is circumstantial evidence that your statement is incorrect, in the blockchain (401302/401303) which you have not offered any explanation for.

You have not provided any factual evidence of you claim above, and so I have to assume that it is wrong.

If the statement is wrong then you demonstrably have a flawed understanding.

If your original assertion relies on a flawed understanding then the original assertion cannot be held true.
