so the ant pool stats page looks like. 1 sec block
the btc.com. shows. 6 seconds
inconsistent .
I think block timestamp variance is normal, some explore to use the "mined at" timestamp, they extract that from the block itself, others use the "received" time which is the time that their node became aware of that block, and it takes time to propagate the block, so it's there is no problem with that.
The strange thing, however, with block 628,427 is that Antpool reported 2020-05-01 15:15:
53 while explorers (including those oweded by Bitmain) reported 2020-05-01 18:15:
47, one would think that the pool's time should be
less since the pool first finds a block and THEN sends it out, I think the status on the pool pages are not accurate.
You should keep in mind that the time displaying on every other explorer is under the control of antpool anyway, since they are the once who put it, they also own btc.com so they could change the status there too, I think this is only a bad input on the pool side, they might very well be counting on the miner's time and just so happened that miner's clock was off by a few seconds, since we don't know how does the pool itself gets it's timestamps, we can't conclude anything.
but of their 2 blocks I checked
628428/628427 was 1 or 6 seconds apart
624652/651 was 31 or 34 seconds apart.
I am looking to do 2 things establish that 1,2,3,4,5,6 second variance in reporting is random and neutral or favors ant-pool
and see frequency of
1-15 second empties
16-30 second empties
31-45 second empties
46-60 second empties.
antpool is the biggest pool it should have the most empties = fact simply because it is more likely they anyone to do a 1 second block.
but the four groups above for bitmain should have for arguments sake
1-15 = 30%
16-30 = 25%
31-45 = 25%
46-60 =20%
I have no idea what the % will be or should be I put those up for a simple reason
they should be roughly the same if you use the
unknown or f2pool or btc.com or bw.com
the time ratios for all bigger pools should not be far apart.
if antpool has a really different grouping it indicates intent
ie
antpool
40
30
20
10
all other pools
25
25
25
25
would be interesting to know they simply match the others and are bigger then the others or they do something to alter the ratios. of time.
I am pretty sure they did not doctor all time stamps on the other pools if they doctored theirs this would show a big difference.
If they match more or less they could just be bigger.
the four category time ratio for empties could be helpful .
put another way they have 17% of the empties and roughly 15-18% of the network
but do their empty block time patterns match that of the other big pools empty block time patterns.
