Sounds great! Let me know if you need help reviewing whether the paper/post is dumbed down enough so even people like me can understand it :)

We are working on a whitepaper that's specific to the Bitcoin application, written in a less academic style that explains our threat model etc.

Nothing too special - we dump all the UTXO's from a full node that we run, and then concatenate and gzip data about each address (balance and recent txns).

Yeah, the delay is because the dumping actually takes quite some time. It's not as easy as you'd think to quickly dump UTXO's from bitcoind. I'm sure we can reduce the delay, especially if we're able to fundraise, hire folks, etc.

Cool! @blintz, it would be great if you would add a quick intro with diagrams about how this works. E.g. take Figure 1 from the paper and update it specifically to Bitcoin :) 

Does the blockchain need to be indexed in a special way ahead of time? Or is this somehow accessing the usual blockchain data?

FYI: There was a delay ~7 minutes for the transaction to show up after the block was mined.
