We've got one Alexandria node recording historical market data from Cryptsy, Bittrex, and Poloniex

http://florincoin.info/explorer/messages/

I'll offer 70,000 FLO for anyone who builds an open-source web application (javascript would be a good choice) that can take an array of these JSON strings and turn it into a nice looking graph (using d3 or highcharts or something similar).

Example JSON string:

Code:

{"alexandria-history-record-datapoint":{"title":"FloMarketData","address":"FF9r36Ua3Ds4itz29hzbfqjkMpoTZ8HEqT","timestamp":"1435242572","api":"http://colorcoin.org:41290/flo-market-data/v1/getAll","unixtime":1435242563,"cryptsy":"0.0865","poloniex":"0.2139","bittrex":"0.6996","daily-volume":"190266.31250000","weighted":"0.00000751","USD":"0.00185"},"signature":"H2N9+nFzO/p2FB7QbzuvcwFbJV88pI9ocZdZGAERIs2/OrK5RZ658BlAPLqmIjT22rBYSAhS19AJFRwCxVoN/B4="}

If you want to run your own market data indexing program, check out https://github.com/metacoin/flo-market-data -- the source code for the Alexandria node (the part that publishes to the blockchain) will be available soon.

Our "Librarian" node (we'll explain this concept in much more detail later on) is actually capturing and archiving the Bitcoin-USD average hourly as well:

Code:

{"alexandria-history-record-datapoint":{"title":"Bitcoin Average Summary","address":"FF9r36Ua3Ds4itz29hzbfqjkMpoTZ8HEqT","timestamp":"1435256972","api":"https://api.bitcoinaverage.com/ticker/global/USD/","24h_avg":244.16,"ask":245.04,"bid":244.84,"last":245.0,"volume_btc":44865.37,"volume_percent":84.24},"signature":"H2UoNtmXlJsotmFr7HCpKp4XpGw8Uvqd3mQw+yYPsKkgqe8vvbp640/23oZxdGjYcqxl/UE5Gc02T+LeylN2I4U="}

I'll add another 30,000 FLO to that bounty, for a total of 100k - anyone interested in building the FOSS web-application Joey described above should PM him or I to discuss.
