Over the past few weeks, we have been able to post regular Darkcoin updates in regards to the progress being made by the developers and community. While we all love positive news, sometimes we have to bring bad news. In this case, a flaw in Darksend has been found and needs to be fixed.
The developers have asked all Darkcoin community members to stop using the Darksend feature until further notice. A flaw in Darksend was discovered two days ago, and the DRK developer is currently working on a security patch.
“This issue comes from the way fees are paid in Darksend with the combination of the way the client tries to denominate the same amount each round. The result is the possibility to trace a transaction through Darksend.“
-Evan Duffield, Darkcoin Developer
In order to fix this flaw, a mixing stage will be added to Darksend which only mixes fees. Furthermore, the client will mix random amounts during each session, obfuscating transactions from the blockchain and restoring anonymity.
According to Mr. Duffield, the security patch is roughly 50% done as of this writing. It should be completed at some point tomorrow, after which it will be tested on the DRK testnet. There will be no need to hard fork the Darkcoin network, making this patch risk-free to users.
