The fork was an upgrade to the Ethereum protocol that occurred a couple of days ago to address several outstanding issues . One of these issues was that the blockchain had become bloated with nullvalue accounts , so EIP 161 was one of the changes in the fork that would fix this . But because Geth made an error in the way they wrote that code , what Geth sees differs from what Parity sees . So Parity users are fine , and the network chugs along , but Geth users can ' t do much . until it ' s fixed . <| sep |> Thanks for all your input guys , all of them look great lol , I guess I ' ll have to pick my favorite style , although the arizer air looks awesome . Thanks friends ! <| sep |> Thanks . I haven ' t been able to see the criteria for each class from a reliable source .
