Hey all,

I was wondering if it is possible to extract the daily average mining difficulty over time from somewhere. Ideally in a .csv format for the last year?

Hey @den,  
for storing zcash difficulty over time starting now I would suggest this API: [API - Zchain](https://explorer.zcha.in/api)

For getting old data, the latest I could find is here: [Zcash Difficulty Chart - ZEC Difficulty - CoinWarz](https://www.coinwarz.com/difficulty-charts/zcash-difficulty-chart)  
latest 3 months available for the public but not in json or any other usable format.

thanks for the links !

I wanted to have a daily average for the whole last 12 months and compare them with the revenue I got from Genesis mining and make some sort of report… I wonder if it is really following the difficulty…
