Title: Difficulty change data
Post by: OVerLoRDI on March 18, 2011, 12:27:29 AM
I'm trying to find data on the difficulty levels similar to what was offered at http://nullvoid.org/bitcoin/difficultiez.php

Sadly that site has been down for quite a while.  Does anyone else have this data or know of a place to get it?

Thanks

I have no idea what used to be on the NullVoid site, but here's where I get my difficulty data:

According to http://bitcoincharts.com/   ...

Estimated Difficulty = 66983 in 953 blks

Edit: Now ...66806 in 950 blks

looks like the difficulty is gonna drop for the very first time since the creation of Bitcoins? Wht do you think might have happened?
Some collapse of the mining pools, or maybe all the CPU miners shutting down at the same time because it really is a waste of time now? (looks to me that with 100Mhash/sec you pull out more or less 1 BTC in 24 hours right now), or maybe just that some miners are quitting after they speculated enough? General loss of interest?

The difficulty has dropped before.

It's dropping this time because before it was adjusted last, someone with a massive amount of hashing power joined the network for a short time, and ramped up the difficulty. They turned off their miners though and so the network is adjusting.

It was really bad timing with that Slashdot article for those who have been mining all the time. We had been mining at a high difficulty for more than two weeks, and when we're finally at the end there's a flood of new miners. This means the decreased difficulty will be probably be used up in less than 10 days, and then it will go even higher than it was.

well, I think it might actually be quite the opposite:  a high mining difficulty could discourage people from trying to mine using only their CPUs or "older" nvidia cards (up to 35 MHashes/s), even by joining pools.

That's just wishful thinking, the next estimated difficulty is 89086 right now.

I think I can now declare myself officially unlucky. Mining both solo and in a pool, 24/7, I got my expected two blocks during the last difficulty level.

Both of them went to the pool.
