Collisions vs Hashs?
« on: December 28, 2013, 11:37:30 PM »

Hi,

this might be a bit late. I want to update the IRC bot from hashes/minute to collisions/minute but I cant figure out the difference.

This is how I calculated the initial network hashrate in H/min:
Code: [Select]
hashrate = (diff * (2 ** 32) * 60.0) / blocktime
But how to calculate the network collision rate in C/min? Is it comparable?

Bump, anyone? Whats a hash, whats a collision?

Please some miner-devs explain me how to calculate network collision rate... :)

From my understanding, hash is a good metric to use for adjusting the speed of an algorithm. Collisions is a better measurement for PTS since it is used to estimate your chances of finding a block, so it's unnecessary to "find" the network collision rate.

Your hash rate and collision rate is different since everyone's hardware is different and each is mostly likely clocked at different speeds with different voltages. Here are two websites for references.

Hashes (Litecoin since most people uses GPUs to mine it but you can look at the CPU section

Collision.

And here is the network hash from coinplorer

is 20 collisions per minute pretty good speed? How many collisions per minute would be needed to
mine one Protoshare per day?

The amount you mine should decrease as time increases. Therefore, there is no accurate answer to your question. You can try to estimate that by finding how many PTS you are getting a day then go from there.

Please dont go offtopic in this thread. The question remains:

Times 4 seems to be pretty accurate so far, resulting in alsmost correct numbers with .solo

Afaik i hash can provide 0-8 collisions, thus 4 at avg (4.5?)
