So this is not withholding block finds and broadcasting the transactions one after the other?
It doesn't seem to be, but it would be difficult to know for certain. If it can be demonstrated that this orphaned other blocks, that might increase the suspicion, but even then it would be difficult to prove with any certainty that it was any type of bock withholding attack.
They seemed to scaleback to 22% for fewdays
Or, they just got less lucky for a few days?
then back to 30% today
Or, just got a bit luckier today?
for the jackpot rolls.
What are "jackpot rolls"?
This is beyond luck or chance.
It looks perfectly normal to me.
BTC.com 46 30.87% ,<---gain %
AntPool 25 16.78% ,<---lost %
BTC.TOP 17 11.41% ,<---lost %
antpool lost hashrate..as did btc.top then we see the jackpot streak again.
You've got that backwards...
It is impossible to know what the hashrate of those pools is. What we DO know is how many blocks they admitted to adding to the blockchain.
The ESTIMATED HASHRATE is calculated by counting the blocks that are solved and the speed at which they are solved. So, when they solve more blocks, it increases the ESTIMATE of their hash rate. When they solve less blocks, it decreases the ESTIMATE of their hash rate.
