As we reported in our final article yesterday, a flaw had been discovered in Darkcoin’s anonymity feature Darksend. A new version , which includes the patch for this flaw, is currently available for testing and it brings quite some changes with it, so let’s take a look!
For starters, Darkcoin masternodes can now make a limited amount of zero-fee transactions for Darksend. These are special transactions which all require a signature only the masternodes can create. No word yet on how many transactions each masternode can make exactly.
Darksend has no more fees whatsoever, contrary to a previous small fee per transaction. The only denominations to be found in Darksend transactions are actual Darksend denominations, and no more DRK fees.
While the Darksend operates on a per-round basis, it turned out to have been a flawed system, as it was vulnerable to attack. As a result, we now have a subscription-based Darksend model. Said subscriptions are the exact amount as a collateral charge, so if you find yourself being charged collateral, it is simply buying more time for Darksend.
Masternodes are important in regards to Darksend and the Darkcoin network. Seeing how anonymity is the key of success for DRK, clients will now remember which masternodes they have used in the past, and not connect to these same nodes again. This make the entire process of using Darkcoin and Darksend even more random and untraceable.
The most interesting part of the V16 code is the fact it contains the full release of InstantX, which allows nearly instant transactions between users worldwide. Unfortunately, the InstantX feature is not enabled in this release, so it can not be tested at this point.
Other changes and fixed are included, and you can find the full list by clicking here.
