There is NO issue with Darksend, in fact the new masternode blinding system is quite impressive.
************ Please Update To 11.2.22! ****************
- DS Speed Improvements : Darksend should be lightning fast now on mainnet. We're going to delay the implementation of masternode blinding because there's two separate mobile wallets that are in the process of implementing Darksend and the reference implementation needs to be super stable during this period of time. Once we have the mobile wallets done (which should have Darksend and InstantX support) we can move back to improving Darksend.
The new masternode blinding system is SO impressive he couldn't figure out how to implement it

Instead, Evan decided to tell everyone Masternode blinding is
delayed due to excuses, then never speak about it again.
#FAIL
#LIES
From the outside looking in it appears that Evan does the following:
1. realizes that anonymity is the hot topic .......BETTER DEVELOP ANONYMOUS CODE!
2. anonymity dies down as a hot topic...
3. speed is now the current hot topic.... BETTER DEVELOP FAST TRANSACTION CODE
4. speed dies down as a hot topic...
5. scalability is the hot topic (given bitcoin's block size issue)...... BETTER DEVELOP SCALABLE CODE!
....
You can guess what is the next step...
