F2Pool is suspected of fraud related to the time of generation blocks
Claims occurres from researchers at Hebrew University who brought charges against one of the largest cryptocurrency mining pools. The reason is that the generation of blocks does not occur properly and this gives the pool the opportunity to get advantages in earning rewards.
According to the university during ETH-miming the miner has “freedom” and can put block times earlier or later as is needed. While the metrics are within the limits it is considered as correct. But in this case this allows the blocks of different miners to be “replaced”.
The accusers from Aviv Yaish, Giland Stern and Aviv Zohar revealed that F2Pool had been using such a strategy for at least two years and got higher rewards for all these time.
In response the pool's co-founder said he respected the consensus and, if anyone has an objection, make Tim Bako send a new version of the manifesto.
Some experts in the industry are confident that working on PoS will solve these problems fast.
