I saw this on Twitter and was wondering if anyone could help me understand?
"For everybody holding #Darkcoin - Google 'Sybil Attack'"
I don't have the technical background to understand a Sybil Attack. Could someone explain this to me and if it negatively impacts DarkCoin's future at all? Might end up being nothing but I would like to know.
Basically a Sybil Attack is an attack on peer-to-Peer network in which the attacker uses multiple nodes to establish that they are "trustworthy" and then proceeds to use that node "trust" to influence the network in some way. The type of influence depends on what type of network it is that is being attacked - it might be just disruption, injection of bad data , or capturing other user and/or node information.
The name Sybil refers to the girl with multiple personalities.
I'm not sure how this would affect the Darkcoin network, except that a 51% attack is somewhat the same principle.
More likely, it's about whether or not a Sybil attack can be used to take control of darksend transactions. Last time someone asked Evan about the master node controlling the darksend transaction, he answered that a slave node would also sign the darksend transaction. But the two are just varying degrees of the same attack, so that was not a true answer to the question.
