@boutiuqe: As it was part of the requirement that this code is open-source, I believe iquidus posted the source freely available here: https://github.com/iquidus/flocharts

Look nice, do you have source for it ?

Xocel - thanks dude, great work! Bounty sent - we'd love to have you join Alexandria's slack channel, if you're interested please pm me your email addy

Devon

Need to find more time for florin.  Lotta sexy goin' on.   

Thanks xocel! Link added to OP and bounty sent.

xocel has collected my 70k FLO bounty for this project, I think it's pretty much got everything requested  

I should have it up on florincoin.info feeding live from the blockchain sometime this week  

Thanks xocel!

Hey everyone,

So here is what I have made: http://iquidus.io:5000

It's loading dummy data at the moment which you can view here

http://iquidus.io:5000/api/marketchartdata
http://iquidus.io:5000/api/bitcoinchartdata

FLO: F7SW9kFnq5attzLamedneJWv5hjcvCTDvk

Update: There is a contender for the bounty that has most of the work complete.

Thanks for your contributions, Devon and skyangel  

I received a few PMs about this bounty so I'd like to post some clarification on what I'd like to see:


There are two types of historical JSON archives in the Florincoin blockchain right now - FLO trade data and Bitcoinaverage data.

The FLO trade data chart should be interactive, something like you'd see on blockchain.info, with a date range picker at the bottom and mouseover context cards.

https://blockchain.info/charts/market-price

However, unlike blockchain.info the chart should display additional information on mouseover:

• Date
• Cryptsy Price
• Poloniex Price
• Bittrex Price
• Daily Volume
• Weighted Price
• FLO/USD

The Bitcoinaverage chart should be exactly the same, Y axis = last trade price and X axis = time. Mouseover should have the following additional information:

• Date
• Bid
• Ask
• Volume
• 24h average
• Last

If you want to really win the bounty, add a dropdown box to select the value for the Y axis as well as displaying the extra data points on mouseover.

Important: don't worry about sourcing the tx-comment JSON, you'll need to run a full node to have the blockchain indexed in a database for that. I already have this database on florincoin.info and the bounty is for providing front-end code, not another block explorer (though you're welcome to make one if you feel so inclined)! For research and development you can use some fake data, as long as it's formatted properly I should be able to plug in the historian data easily. Who knows, maybe I'll make an API for the block explorer this weekend just to make it easier for you guys

I'll match the 30,000 FLO for a total of 130K.

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:

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.

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:


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.

Finally a coin I've bought that is becoming really big!! Good job with alexandria!

These are good questions, thanks for reminding me to test Alexandria out on my RPi 2.

Bandwidth questions about streaming quality / seeding mechanics are not known to me at this time. Perhaps I can look deeper into the IPFS codebase to figure it out. (We've switched from BitTorrent to IPFS recently).

Cool, how about if I have a giga bit server that upload the movies, then other will streaming it online, is it make different than my home PC like 50mb/s ?
Or still calculate through the combine seed actual online at that time ?
This is very interested.
Is it RPi 2 seed vs PC seed ( p2p ) , any of those make different from streaming speed ?

Since Alexandria users don't download from a web server with known bandwidth limits, that's not really something that can be quantified very well - it will vary depending on what piece of media you're downloading and how many other users are currently seeding it.

http://gateway.ipfs.io/ipfs/QmUNrsYdFLfQxrgTdjV7wLYL8CLZWjJyhGWu9ZvRu7AJoT

Now my caveat is that right now the "it just works" version of the Alexandria browser defaults to "Gateways" so that users don't have to install all of the daemons necessary to run things in an entirely p2p way - so those users *would* in fact be using web servers for downloading, but since there will be many gateway options available and users will be able to switch between them in their preferences, it would again be pretty impossible to actually say what the dl or ul rate is for Alexandria in general.

(edit, added this) Oh, all that said - we've generally found that with ~10 or so seeders with a average speed internet connection, an HD movie or FLAC audio file can start streaming pretty much right away.

So we will able to upload HD movies.
What is download and upload rate from Alexandria ?
