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.
