Here is an interesting paper I found from 2014.
http://p2sh.net/file/Purely%20p2p%20crypto-currency%20with%20finite%20mini-blockchain.pdf

I don't know if it's exactly what Bytemaster is looking for but it's what I could find so far. Anyone want to take a look at it and see if it's helpful?
ZeroCash paper: http://zerocash-project.org/media/pdf/zerocash-oakland2014.pdf
Extended version: http://zerocash-project.org/media/pdf/zerocash-extended-20140518.pdf

ZeroCash claims to improve on ZeroCoin by using zero knowledge Succinct Non-interactive ARguments of Knowledge (zkSNARK), bringing transaction sizes down to <1KB and verification times down to <6ms.

Here's a work in progress C++ library for zkSNARKS: https://github.com/scipr-lab/libsnark

Libsnark is so complicated I don't know anyone in the industry except the developers working on it who understand it. I think if we do pick an algorithm or cryptography it helps if it's simple enough to be understood. When you implement something no one understands there is risk in that.

At the same time it's said to be the most private option available.

I can investigate further if you let me know what you're after, but I should warn you that I really don't understand the math behind these at all.

About Nxt,:
I just use the web wallet of Nxt at secureae.com.  How long of its sycn time is not important to me.

Sync time is VERY important to understand scalability of the architecture of the "miners".... and not DOWNLOAD time but REINDEX/REPLAY time that removes all network sync overhead from the calculation.

I would like to do a survey of the most advanced tech in the industry.  The goal is to aggregate all of the "ideas" into one place and label / sort them.  This can be thought of as one of the largest repositories of white papers out there.    The purpose of this is to help me keep up to date with the latest ideas without having to search for it all myself.

I would also like some help gathering performance measures / benchmarks of our primary competitors.  So have the following questions:

1) What is the fastest implementation of reindexing the Bitcoin blockchain without signature checks, how may transactions per second does it process.  This would probably be like reindexing Bitcoin prior to a checkpoint.

2) How long does it take to do the equivalent of reindexing with Nxt?   how many blocks and/or transactions per second can Nxt reindex.

3) Same question for Ripple

4) How many transactions per second can Etherem reindex?   How many operations per second can their scripting engine execute? 

The goal of these benchmarks is to evaluate how well the existing implementations scale in the real world.   

Today BitShares can reindex at close to 1000 transactions per second.   This hits the limit of the current implementation, but an updated implementation could easily get BitShares up to 10x that.   

I would also like to know everything there is to know about multi-sig technology offered by the various platforms. 

Lastly a survey of the various approaches to zero knowledge proofs for cryptographic privacy on a blockchain.

Why not just use a Google alert? Or do you want someone to read the papers and organize it into some kind of wiki? Maybe you want a SWOT analysis?
https://en.wikipedia.org/wiki/SWOT_analysis

In any case maybe I'll be able to help out. I read a lot of whitepapers.
