It includes dynamic charts and visualizations with drilldown capabilities to explore bitcoin related data.It makes use of the following technologies: For an explanation of Bitcoin please visit Khan Academy's explanation of Bitcoin A screencast is also available on Youtube in case of a server downtime Read further for more details about the project As of September 2014, the Bitcoin block chain (the transaction log since the creation of Bitcoin) is over 320k blocks long.On average a new block is added to the chain roughly every 10 minutes, and each block contains a list of transactions and also new bitcoins added to the pool (process of mining).The historical block chain data is over 25 GB in total and can be accessed by querying the bitcoin client.The pipeline obtains data from the bitcoin client using a JSON RPC API.The bitcoin client allows querying for specific blocks (by hash and by block #) and responds with JSON formatted data./ajmssc/bitcoin-inspector-webserver/tree/master/bitcoin) is used to query periodically for missing blocks and transactions, and a realtime job also in Python monitors the memory pool of the client to detect new (unconfirmed) transactions.

(Bitcoin Exchange) website for monitoring the exchange rate in various currencies.The data from the bitcoin client is converted into Protocol Buffers to strip the json headers and validate the data, and base64 encoded to allow easier decoding by the mapreduce jobs.It is then sent to Apache Kafka in 3 separate topics: Hourly jobs then consume the data from the Kafka topics and save it directly into HDFS (see kafka_to_hadoop*.py).The files are tagged using a timestamp.bitcoin geenstijlI implemented 3 levels of aggregation for event aggregation (count of blocks, transactions, etc...).bitcoin fixed return miningCreating 3 key/value pairs out of each data point allows for querying the time series at different "zoom" levels.bitcoin from bank account

When pulling all data in a chart from 2009 to 2014, it is more efficient to pull daily aggregates because the data volume at a minute level from 2009 to 2014 would be huge and computationally intensive for HighCharts to render.After zooming in on a more precise range (ex: 2 months), we can use the hourly level aggregate key to obtain more granular data for a smaller interval.We do this again when zooming in on a 10 day interval where we are now interested in looking at the data by the minute.bitcoin hoe kom ik eraanTo do this calculation I used MapReduce jobs that output 3 keys out of each timestamp (see Batch Processing diagram).hileman bitcoinThe Flask API script dynamically selects which key to use based on the range of the query (less than 2 months => hourly, less than 10 days => minute).bitcoin gtk client

Highcharts automatically reloads the data and adjusts the upper and lower time bounds.I used Yelp's MrJob project to run MapReduce jobs using Python.I used Apache Storm to provide real-time aggregates and do simple data processing.Instructions are specific to Debian/Ubuntu.Install Kafka (see my tutorial, Storm, and the Bitcoin client.Apache ModWSGI to Flask configuration My presentation slides are available at http://www.slideshare.net/Jeanmarcsoumet/bitcoin-data-pipeline-insight-data-science-project789Does anyone have a raw text file (CSV) with historical bitcoin price data accurate to the hour?(self.BitcoinMarkets)submitted by I know how to get a CSV of historical price data accurate to a day, but I'm working on some trading software that I would like to test against more granular data than that.Hourly would be nice, every ten minutes even nicer.Does anyone already have that laying around as an ASCII text file?I'm writing some trading software and I want to test strategies against historical price data, I gotta guess I'm not the only person who has wanted to do this sort of thing.
