Well that does it, I will feel like an ASS if I do not donate for all the amazing stuff you have done. Thank you sir! How/What method are you using to estimate the solo hashrate? Are you going for a more accurate estimation (average over a longer time period) or more current update (shorter time period to help notice hashrate increases).
Currently I'm using the percentage of the mined blocks from the last 48h. (I used 24h before, simply because we were solomining for < 2 days ^^)
Check the last graph from www.asicminercharts.com, and zoom to the last 5 days. The hashrate from solomining fluctuates pretty much but will smoothen out by using the 48h instead of 24h average
I've asked them to fix their API on the forum a few days ago, but no reaction until now..
Code:
(2^32 * difficulty) / average_time_between_blocks = hash_rate
So if we take the timestamp of their newest block and subtract the timestamp of their first block, we get:
Code:
1369308020−1369069056 = 238964 seconds
They have mined 47 blocks in this period, so to get the average time between blocks, we divide 238964 seconds with 46:
Code:
238964 / 46 = 5194.87 seconds/block
Now we plug it into the first formula to get their average hash rate over the entire period of their solo mining:
Code:
(2^32 * difficulty) / average_time_between_blocks = hash_rate
(2^32 * 11187257.4613608) / 5194.87 = 9.249298814×10¹² = 9.25 Thash/s
(2^32 * 11187257.4613608) / 5194.87 = 9.249298814×10¹² = 9.25 Thash/s
This is what I've done with the graph on my site: http://runeks.dk/bitcoin/
It updates the every time a new ASICMiner block comes in. Currently it just tracks the all-time average (because we don't have enough data yet), but over time I will make it track a 2-day, 5-day and 10-day average:
