Can anyone comment on the privacy solution offered by BTCD? They have termed it Teleport and Telepathy.
Teleport seems to have components of XMR's solution to privacy:
"In a mantissa attack you are identified because of the exact size of your transaction.
That makes your transaction distinctive among others and it is easy to spot you on the blockchain.
To remove this threat the telepods use standard denominations, i.e.100, 50,10, 5,1 and so on."
I've seen comparisons of XMR with other anon-centric coins but not with BTCD.

Unless it has been reworked from the dark paper last year, it is worthless and doesn't solve any of the problems that blockchains exist to solve.
You send your telepod to the recipient. The recipient can either submit it on the blockchain, it which case it ends up looking exactly the same as if you spent it yourself. Or they can pass the telepod on to another recipient, which in theory delinks you from the first recipient (though you are now linked with the second, which for all you know might even be worse, and vice versa). What is to keep first recipient from passing the output on to two parties (effectively a double spend) or to keep you from double spending the output while it is being passed around? Nothing.
So:
1. Ignores the need for double spend protection
2. Transactions are still strongly linked to some actual recipient on the blockchain (even more so than coinjoin), by at best a small number of hops, maybe none.
Other stuff in BTCD like the asset exchange might be worth something -- I haven't evaluated it -- but the privacy stuff is just nonsense.
If there is something new going on, I'd need to see a new paper, though frankly I'm not sure I would put in the effort to read it. Getting through the dark paper was excruciating.
