Re: [ANN][KMD][dPoW] Komodo - Zcash Zero Knowledge Privacy Secured by Bitcoin

So if the hacker was able to mine block after block... does that indicate the hacker is running a notary node?...... as Notary Nodes get to mine most blocks......I'm asking this as I have not seen this conspiracy theory

raised yet..... I struggle with lets run decentralized coin by centralizing most of the mining power, sounds a little oxymoronic to me.......Anyway if someone can explain how someone could mine block after block I for one

would love to know how....AFAIK this is the real question

Cheers Jon Wink

I understand

notary nodes sign each block they mine
attacker used GPU to mine and when he was the only one left mining on his chain, he was getting all the blocks.

you can do that with any coin, even bitcoin. Just disconnect from all peers and start mining. When you go on a fork, you often end up mining many blocks, its just not anything others will recognize.

64 nodes is a bit of a distance away from being centralized. Many coins have about that many total nodes. KMD has all the notary nodes, plus mining pools and independent miners, all able to mine blocks. Current balance is about 70% notary nodes, 30% others, but some of the big mining pools are not back online yet, I think we will end up in the 40/60 to 60/40 range.

By dividing the blocks in to roughly equal halves, neither population can get any confidence to conduct an attack and this provides more security

Thank you for your reply. I understand mining your own fork...... I don't understand how could they then move them onto exchange if they were not recognized on real blockchain. Surely the

transaction should never have been confirmed during deposit to exchange.

As for centralization...... being ether one of 64 who get to mine 50% or one of millions who get to mine 50%, your correct very little difference

There was a bug that allowed him to create more coins each time he found a block. The bug was similar to the bug Bitcoin had in its early days.

Any updates on a bug free wallet?

Yes,

A lot better version can be downloaded from here: github.com/SuperNETorg/iguana/releases

We are going to make installers, and after that it will be available on supernet.org too.

Reaction to the threat is impressive, just need assurance it wont happen again, a promise for a future rally. provide more trade in poloniex to impress and improve the demand.
