firstly. i was dismissing the fud that pools like viabtc do not own a full node and only have a litewallet to their name'(SPV).. as that FUD is completely factually incorrect.. the myth that pools only own litewallets(SPV) was done so to create some propagandist FUD that pools are dirty, nasty, dangerous to the network (a rhetoric being passed around for the last 7years)
I hope you are not confusing SPV mining with running a SPV client.
Doing SPV mining doesn't mean the pool is running a SPV client. That just means that they run a full node but they have modified it to
postpone full verification of the blocks or the headers they receive and only verify the header just like a SPV client would and then build on that.
They could also do "spy mining" where they spy on other pools to be able to get the new header even faster and build on top of that without receiving the block or the header through the P2P network.
actually they do not postpone verification..
they actually do do full verification..
they just do not postpone working on a new block until verification.
which is what you think pools do.
sorry to burst your bubble but not all pools just turn off their asic miners for a few seconds while the pool does some checks..
your premiss is still trying to suggest that viapool(this topics exampled pool) doesnt even bother validating when it works on a next block.
or your now trying to suggest that all pools just switch off their asics and give no work for X seconds until all verification is complete..
when infact they do the verifcation AND also mine at same time. they just dont do it in the order you think. nor the way you think
