It means that the network is used by more powerful miners. Difficulty adjusts to the network hashrate (after every block, unlike Bitcoin which adjusts difficulty only every 2016 blocks, around two weeks for 1 block / 10 minutes), meaning it will be more difficult to mine a block the more miners will join the network (if the overall hashrate goes up).
The Monero network targets blocks to be mined at 120 seconds, using the difficulty so that hash_rate = difficulty / block_time, ie difficulty = hash_rate * block_time.
Unit analysis gives the difficulty unit to be hashes (H/s times s).
It is the expected number of hashes spent looking for a block.
The difficulty is simply a number specifying the maximum size for a block's PoW hash. With a difficulty of 80926050199, a block's PoW hash (represented as a big endian integer) must be below a certain number which you get by plugin in 80926050199 to a formula (essentially meaning the hash needs to start with a certain amount of zeros).
Note that a block's ...
With a difficulty of 80G, the network will need to try 80 billion hashes on average to find a new block. The difficulty is adjusted to target a block every 2 minutes or 120 seconds.
So a difficulty of 80G is based on the assumption that the current network hashrate is 80 billion / 120 = 666 MH/s.
If blocks are found faster than expected, it means that the ...
You can find the difficulty of a submitted hash (which is just a big endian hex encoded string) by dividing the base difficulty (2^256-1) by your hash.
As such, nodejs-pool (the most common pool software), checks your submitted hash difficulty as follows:
let hashArray = hash.toByteArray().reverse();
let hashNum = bignum.fromBuffer(new Buffer(hashArray));
How to get a decimal value of difficulty (480045) by a hexadecimal value of a given target in hex (f3220000) ?
Swap endian f3220000 and remove padding gets 22f3, then 0x100000001 / 0x22f3 yields: 480045.
How to get a hexadecimal value of target (f3220000) by a decimal value of a given difficulty (480045)?
((2^256-1) / 480045) >> 224 is ...
The difficulty is a numerical representation of how long on average it
will take to create a valid block that satisfies the Proof-of-Work
algorithm being used, it does not represent minutes or time per se.
but instead is an integer number that makes the PoW calculation take
longer to perform, this is adjusted by the nodes and miners so that on
The port used defines the starting difficulty.
From the pool doc you referenced:
The Port is used in conjunciton with the url and is used to specify the starting difficulty.
As soon as you submit a result, the pool updates your difficulty for the next job it sends you based on how long it took you to hash the last (or to be more accurate, it averages ...
You're are correct in assuming target is the same as difficulty
Question 1: You are just credited for the difficulty nothing more. You are set with a threshold to meet to prove you are mining however these shares hold no value unless they are the solution to the current block so you will not be rewarded extra for mining below the threshold, neither will you ...
