Chia founder Bram Cohen has just tweeted that some of the Chia mines with security concerns claim they have problems falsifying space certificates, which is not really a problem at all. At the very least, assuming they're in the fully validated section, who knows what I'm not checking for, but more so they're effectively checking the part, but allowing users to join pre-existing blocks and just hope that the malware they're farming on the user's machine succeeds in preventing them from retaining the reward when they actually find the block. Such an approach is cunning. Blockchain should be used to evict fraudsters without trusting others and using real identification and exploratory methods. Blockchain should use a truly secure protocol. Chia's entire team is now working on our new standard pool protocol, which not only allows users to jump between pools at any time, but also prevents fraud.
