Been looking for a decent replacement to the PPC every block retarget algorithm. KGW, DGW, DigiShield, whatever else does no good. Have got the job done myself finally.
https://github.com/ghostlander/Orbitcoin/blob/1e417b40a65dc316037855b1d3db3b32165c80db/src/main.cpp#L1157Re-targets every block with separate fixed targets for PoW and PoS. Two averaging windows (short of 5 blocks and long of 20 blocks), both are limited against time warping. Interwindow averaging and 0.25 damping with the final +1% / -2% difficulty limiting. Runs fine so far.
P.S. Though BOB has Coingen roots, Testnet does work. So that's always an option. Though the seed node can be wonky at times.
OMFG, this Bobcoin spam is now here at Bitcointalk. This annoying Coingen nonsense will get killed some day. The sooner is the better.
