I've been looking at the Freicoin difficulty to predict what it will be at the next change. I've pulled data from the Freicoin hashrate graphs shown below.
Source: http://www.freicoin.org/freicoin-hash-rate-graph-t82.htmlI got together the date of the difficulty change and the second chart above to check the hashrate at the point of change. The first chart is logarithmic.
Date of change - First block after change - Difficulty - Approx Hashrate
2013-01-03 15:56:56 - 14,112 - 9,772 - 104Gh/s
2012-12-28 19:07:08 - 12,096 - 4,096 - 52Gh/s
2012-12-25 13:25:15 - 10,080 - 1,024 - 30Gh/s
2012-12-23 18:36:44 - 8,064 - 256 - 7Gh/s
Difficulty changes every 2016 blocks so we can expect the next change at 16,128. The current hashrate is 57Gh/s and if this keeps going we can expect a new difficulty around 4,096. The network is progressing at around 100 blocks a day so we should expect this change in 10 days time on the 24th January.
