There is a known flaw in stratum that allows you to submit many more shares than you actually could mine. So you can mine with let's say 100KH but make it appear that you are mining with 10,000KH. They are not actually providing that amount of work and coins are not being mined faster.



What happens is that since the pool thinks that they are mining the lion's share that they deserve the majority of the coins that are actually mined. So you fake 95% of the pools hash power and get 95% of the coins mined when they were only putting in a very small share.



This is an old issue that has come back to life with pool operators using unpatched pool software. The issue has been raised in on GitHub and a an example of how to recreate the problem using a mining stratum proxy is in the link below.



https://github.com/Crypto-Expert/stratum-mining/issues/313 There still seems to be some confusion over the large miner over at ForkPool. That large miner that people thought was botnet is actually a small miner generating a large number of fake hashes.

We will be the new home for GPU miners when those Scrypt ASICs hit.
