I see CAP now have 185% rate just because one of nodes have -60 min time shift. It is because developer had tried quick fix one bug (time wrap stuck), but create another.
PS. To fix this bug, just need return original function GetNextTargetRequiredV1 and reduce max time drift to 3 min.

I analyze tx from that 3 address. All belong to attacker on Cryptopia and it was not first attack. Previous was October 8,9,10. Admins from Cryptopia, it is hacker addresses: EvkWsGkW1xFhNxCMDMFG7rHjF4vc23xy2D F4GqUVjQAu2dQJeUejisw5HxbooP5CjFCJ EyViNxLswJm8Ar8KT3MTPm6hfMrjXHmtCW
Summary hacker stole 36M CAP from Cryptopia.
New hackers addresses for next attack: from 82 to 160 in rich list.
PS. Better solution will be create new coin (Hyperstake clone) and send all premine to current addresses, except hackers 82 to 160 in rich list.
I support this option. A new chain would be a lot better for a number of reasons.

So, is it worth our while to keep our wallets open for staking right now?

This would certainly alleviate some issues.

Who is going to be the developer, admin, coin swapper for any of this? Hint, it's not me... Is there anyone who cares about CAPs that has any experience with actually doing any development work? Other then myself? Speak now..

I've been a very small part of this team promoting the coin on various POS coin threads. I don't have much to lose compared to some. It would be great to see more voices chime in here. I'm too busy to know exactly what is going on, but I gather not only cryptopia is losing but many private individuals?
I respect the exchanges, but they are in a better position to take a lose probably than individuals. Almost every exchange has done things to protect their own interests over their customers at times.

I will gladly help for what I can, and if you need peer review or help with testnet, etc I can do this. What is the plan? Fork HYP? and update for CAPs. I think better to fork newest NVC or PPC straight up. I had plans to put some fixes into CAP, but not a complete reboot. Someone needs to control the OP as well. I don't have that user Account. I think it was flound1129 who had it at one point.

I have been apart of several dev teams as well and can give some support. I only own about 400k so I don't have much at stake and most are locked up on cryptopia but can help with support on bitcointalk, website and discord if needed.

New topic already started: https://bitcointalk.org/index.php?topic=2329756.0But I change later some parameters. It will be SCIFI clone with some changes. SCIFI - fork from recent NVC Coin swap very easy, after start I send premine to all old CAP addresses (see BUK swap) User just put old CAP wallet.dat to new directory and start CAPP But first I need obtain consent from Cryptopia.

SCIFI - fork from recent NVC Coin swap very easy, after start I send premine to all old CAP addresses (see BUK swap) User just put old CAP wallet.dat to new directory and start CAPP But first I need obtain consent from Cryptopia. So I think some of these need discussed with the community before they are set in stone, errr code. Some parameters: Block time 2 min Min stake interval 10 days, max 30 Max PoS block reward 100 PoW reward 1 (need for start chain, stop after 1 month.) Max PoS percentage 500% Swap rate 10 CAP = 1 CAPP Premine ~20M or 10% from max supply. Max yearly new coins - 26M real PoS rate: 1st year 100% 2nd year 50% 3 - 33 4 - 25 My opinions: Block time is good Min Stake, might as well make it one day. Just be sure to change nModifierInterval to allow for it Max PoS block reward of 100 maybe too low. I am ok with it, not sure how others feel about it? Pow only at first block? So not a hybrid? I actually like how HBN is doing POW and POS. It forces POW to only come after a POS block. Prevents flash mining but still allows for people to get in with no cash. Swap rate seems ok.. How do others feel? I assume the PoS Rate is just based on number of coins and the reward cap hitting more often, but the base rate doens't change. Do you plan on running checkpoint server. I think this is important to know.

Max PoS block reward of 100 maybe too low. - it if swap rate 10 to 1 I think make hybrid PoS+PoW 1:1 or 2:1 PoW reward 10 Max PoS percentage 360% If have big max PoS reward, difficulty will be low and easy 51% attacked. Checkpoint server run on my home computer 24/7 for BUK2 and SCIFI and also will start for CAPP. Min stake interval 5 days, max 20 (if make 30-60 days - easy for attacker to accumulate PoS weight)
current SCIFI coin parameters: * PoW Algo: Scrypt * PoW + PoS blockchain 50:50 % * 3 minutes stake spacing * 3 minutes PoW spacing * Final block spacing 1.5 min * Balanced PoW blocks and stakes weighting * 100% yearly interest PoS * PoW reward is 10 coins * PoS max reward is 100 coins * 10 days minimum stake interval, 30 days for full weight * Maximum coin supply 175M * Coin maturity: 100 Blocks * PPC type re-targeting (100 blocks window) * Max time drift 3 min

2:1 PoW is good. But still have try to limit flash mining. I agree keep max under 30 for sure, 20 sounds fine. but min can go lower then 5, but 5 is ok. ReydeApio was willing to run the CP Server from a dedicated VPS. If he will still agree for CAPP we might see if that is option. VPS can withstand flood attack if someone figures out where the CP Server is located. With dedicated CP Server, there is little ability to attack.

I can give checkpoint private key to ReydeApio. I have my own special algo to limit flash mining: if(nActualSpacing < 0) // { nActualSpacing = 0; } if(nActualSpacing > nTargetTimespan / 3) //retarget -40% maximum { nActualSpacing = nTargetTimespan / 3; } else if(nActualSpacing < nStakeTargetSpacing / 3) //instamine protection, retarget +7% maximum { nActualSpacing *= 4; nActualSpacing -= nStakeTargetSpacing; }

So, it's official we are going with this then? If so, I'll add CAPP to Crypto-city as well.
