Apologies if this is a duplicate, but trying to add more actual information to the pile of cryptonote derivatives -- BBR's Zoidberg wrote up a whitepaper about his Blockchain PoW construction and its realization in Wild Keccak:

http://boolberry.com/files/Block_Chain_Based_Proof_of_Work.pdf

As a follow-up to his earlier explanations of
Improved anonymity: http://www.slideshare.net/boolberry/boolberry-solves-cryptonoteflaws-37055246
Blockchain pruning: http://www.slideshare.net/boolberry/boolberry-reduces-blockchain-bloat

I'm sure there will be pushback on these as there was to the others, but kudos to him and the Boolberry team for putting it out there for others to read, steal from, and criticize. (Disclaimer: I looked at an earlier draft of this one and provided some minor writing feedback. I'm not an author of it and am not part of the BBR team.)

But...but...

Sorry - I've updated my original post to more correctly note the second presentation is about ring signature pruning, not blockchain pruning, as was discussed at length earlier in this thread. Mea culpa for the uncareful phrasing.

The clarification is much appreciated. My understanding is that BBR ring sig pruning linearly reduces blockchain bloat, but is not the holy grail of transaction pruning required for logarithmic bloat reduction of the kind found in XCN's mini-blockchain.

To be clear, ring sig pruning prevents a little bit of bloat, while transaction pruning removes substantial accumulated bloat.

Also, 'dust' is the atomic unit of 'bloat.'

Did I get that right? What do I win? Cheesy

In CryptoNote coins ring signature is 60-90% of transaction size. With pruning ring signatures you get 60-90% smaller blockchain, compared with other cryptonote coins, you win only this here.

XCN is very interesting project, unfortunately i can't see possibility to build account tree on CryptoNote base(as well as utxo) due to anonymity/unlinkability.
