The upcoming GRAFT network update will take care of problems with hashrate attacks and instability of block intervals (in addition to ASIC resistance upgrade). We would like to share the most recent results of the new difficulty algorithm testing on the testnet. The first graph shows how the existing algorithm slowly adjusts to multiple spikes of the network hashrate: The second graph shows how the upgraded algorithm quickly reacts to virtually any change of the network hashrate: The release candidate build is finalized but we are still in a process of testing of the upcoming network update. We are still on track to release it next week, stay tuned to get further notifications about specific date/time. By the way, if you haven’t seen it yet, here is the most up to date and detailed GRAFT engineering roadmap.
