It looks like the Forks.green Chia Fork Exchange has gone down again with very little communication to its userbase. There isn’t any official information I can find, but I am told that the issue is that the website was hacked and the transaction database encrypted and ransomed, with the ransomer asking for 0.15 BTC which is about $8700 CDN at time of this writing.
Users is in the Chia Fork Russia discord where Forks.Green has its home are pretty upset, again, with the lack of communication. I am on their side. I like the service, I was hoping to interview the developer behind it but until the communication with users improves its going to be difficult to recommend the service to anyone.
If my understanding of the issue is correct, unless they are able to decrypt the database the service as it was is effectively gone with the only honest option being to send back to people what they deposited minus what they have withdrawn in other coins. In other words it will be painstaking effort looking at a dozen blockchains trying to figure out what happened.
