This was a bug in the code, actually it was code that was missing and allowed a vout to be created that wasnt constrained. It is closer to the billions of bitcoins bug.
I announced the block that will be rolled back to, pretty much in realtime, so it is more a stopping the chain at 235300 than rolling back. of course a few hundred blocks were generated during the time to make the fix. so yes, technically it is a rollback of a few hours, of the blocks that happened after 235300 was announced.
Let us not make a political circus out of this. It was a bug that was abused.
The attack started about 36 hours ago during the weekend. We detected it about 6 hours ago and had a fix that would go into effect at 236000. At that point the attacker would have had coins, but it would have been absorbable.
Then the attacker must have seen that things will be cutoff at 236000 and he went wild. He started a high frequency attack and started to move funds, even some z-transactions.
There were 15 blocks prior to 235300 with the illicit KMD in vout1 and the new version prevents any block with any tx that spends any of these 15 as invalid. Unfortunately, this will require a resync of the chain as the local DB has invalid blocks in it and even with the -rewind, komodod will be complaining.
If you are running native komodod, you need to update and resync. delete the usual blockchain files and komodostate in the ~/.komodo folder. Make sure to not delete your wallet.
The simplest is to leave the illicit KMD in the utxo where they are, frozen. So there wont be any dilution due to this.
+1 to the decision to roll back. Dont listen to trolls here. They may be sockpuppet of the attacker. Rolling back chain few hours is no big deal. Those not happy with the Dev's decision can move on.
and stupidity and greed win again wtf

Zcoin is doing very good at the moment. The bug was fixed ASAP and the damage was contained. ZCOIN is at 0.03BTC/XZC at the moment. Not bad for a coin whose price was 0.0004BTC/XZC when the bug was found. In fact the bug discovery nailed the reason for downtrend in coins price and lead to a massive rally of 900% post bug fixing.
Do not fall for it they are only up as they have some huge chinese MLM guy behind them throwing more money than ideas u really wanna end up like that
good luck eh (there is more important things than $$ in starting a coin like this - value will follow trust !!!)

you are nutz do NOT roll back - does not matter how many blocks !!
this is ETH and the bailout all over again ! do NOT be greedy - let run as is - and burn supply after !!!
(should have learned from Zcoin mistakes !!)

Re: [ANN] AMP - The Currency That Powers Your Attention On Synereo
Anybody seen the devs? Are some of them still here? Do you have slack? The link slack.synereo.com does not work.
saw Dor on FB yesterday - he eventually always come back when somebody pinged him he sais: working it - news coming soon i know what u gonna say - but - he replies - so ....
anither coin far from complete and way behind in demand since the flop..there is onky more sia to sell...this selling pressure is getting ridiculus....except if someone is buying 1 million dollar of sia in 1 second, i don't see when i'll be able to profit my investm..ent (i n a year frame) (its very long for the crypto world) lol btc will be 2200 usd then and sia will be 10 satoshi before going to moon its a shame i had alot of hope in sia but he is just doing like every other alt ........crashing like a plane i'm going to loss my btc and the profit i woul have make so in total sia has to go nut if i ever hope to do has much profit as if i would have let my btc be and do nothing except of tchecking every now and then for develepeement and hype and fud and all the stress around...
even better if i would just have lend btc...
My point is why buy sia when everyone is doing way more money by tchilling with btc....(now you get why the price go down down down) witout mentining this atrocious big number of avaible supply + supply own by ppl...
anyway just anither bad thousand $ call i guess i will survive... but my hope in all alt are now dead lol those 5 month have just too much too handle... you guys don't come near the ankle of btc when compared at a profit potential level. Sia and all alt goings to bye bye (2% lucky winner 98% losser)
ah come on 2-3 years ago everybody was bitching about that in the Dash community too and now ? boom 20+ US$ go figure and do the math
