I would like to have a time series of hashing power deployed in a given time to the bitcoin blockchain.gomething like blockchain.info has, but with a custom granularity (they only offer per-day value, I'd like a per minute one).

Problem is I know what hash power is (at least I think so) and I could estimate mine one, had I a running miner client. But I do not know where to retrieve or derive the information about the global one, which is I think the sum of all trials made before a block is mined divided by the time elapsed for the magic number to be found.

I'd think this information is not available anywhere, but blockchain.info seems to have it..so how?

Thanks in advance, and sorry if I am terribly wrong at some point

    See bitcoin.stackexchange.com/questions/72690/…. It's fundamentally not going to be possible to get that kind of granularity. You can't actually observe the hash rate, you can only infer it statistically from the time between blocks. What you're observing is a random variable centered on the true hash rate. To reduce the randomness, you have to average over many blocks, and blocks only come every 10 minutes or so. – Nate Eldredge Mar 20 '18 at 22:28
  • Jameson Lopp's statoshi.info has had network hash rate since Jan 01, 2018. You can see it up to the granularity of 1 minute: http://statoshi.info/dashboard/db/mining. However, I think he rounds it to the nearest Exahashes per sec. – satoshi_ghost Mar 21 '18 at 3:50
