Hello,
In reply to:
http://bitcoinist.net/attack-krypton-dry-run-ethereum/Dear
@covertress, I kindly ask you to stop spreading lies that my pool was involved in 51% attack targeted at Krypton network.
Attack was performed 2016-08-24 around 20:27 CEST, when malicious miner (
http://explorer.krypton.rocks/#/address/0x3476cac2670e87e237b738a54fdce381640e5c05) revealed his blockchain fork (174 blocks) that had more work and was longer about 59 blocks from the main chain. Blockchain reorganization took place and attacker's chain won. All work performed on Krypton network between 2016-08-24 19:25 CEST and 2016-08-24 20:27:52 CEST became invalid and lost. Here are logs:

http://pastebin.com/carHv0S2I am also concerned about the development of the project. From where I can get go-krypton 1.3.3? I see that some of the pools already use it. Is it a version for the chosen ones?
