Topic: Can mining power be compaired to rate of blocks found? (Read 777 times)

Just like Neo found out in the Matrix... there is no spoon.

The network has no concept of hash rate.  All it knows is that at timestamp A, block X was solved and at timestamp B, block Y was solved.  It calculates the hash rate based on that timespan and network difficulty.  Every 2016 blocks, the network evaluates how it did.  The way it does this is again independent of hash rate.  It simply says, "What would the network difficulty have needed to be to make the previous 2016 blocks take 14 days?  Adjust network difficulty to that value."

The key point to this is that the network hash rate is interpolated based upon how long it takes to solve blocks and the target difficulty for those block solutions.

The famous 10 minutes, who on average always had been smaller then 10 minutes except in times of shrinking difficulty. Currently a hot toppic if those 10 are to long. The real number like 9.87654something would interest me.

I assume you are asking about bitcoin?  If you are asking about an altcoin, then the answers to your questions will depend on the specific rules of that coin.  If you are asking about bitcoin then . . .

How do you know they are contributing 1/5th of the hash power? How do you know they are not averaging 1/5th of the blocks founds?  If they are actually contributing nearly 1/5th of the hashpower, then they are almost certainly averaging nearly 1/5th of the blocks found.


No, that's not possible.  If it was, then everyone would do it and the pools wouldn't exist.


If you change the address that the block reward will be paid to, then it isn't possible to be on the same midstate, since part of the input to the hash function that calculates the midstate is the merkle root, and the assigning of the value of the block reward is used in the calculation of the merkle root.


Indirectly, yes.  They monitor the validity of the shares submitted.  If you are calculating a nonce for a different midstate, then most of the time your nonce won't result in valid shares.


In what way?  Miners contribute shares.  Occasionally those shares are also valid blocks.  If they aren't submitting valid shares, then they aren't participating and don't get paid by the pool. If they are submitting valid shares, then they are paticipating and do get paid.


You'd have to talk to each of the pool operators if you want a list of how many shares each participant contributed.  Some pools may not keep that information.  Some participants may be operating under multiple connections, so they may be difficult to uniquely identify.

The bitcoin network is set up to keep the average block time to 10 minutes.  If more miners come online and that average time between blocks becomes less, the network auto-adjusts.  This adjustment comes once every 14 days.

By design, the chances of solving a block are proportional to your hash power. So if you are contributing 1/5 of the total hash power, you solve around 1/5 of the blocks. There is no way to directly measure the hash power of all the miners. It is currently done indirectly by measuring the time between blocks.

When you submit a share to a pool, it verifies your work before crediting you. If you modify the coinbase transaction to point to your address, the pool will know and reject your share.

Are you asking about this in general, or in regards to a specific pool?

In general, the number of blocks found is directly related to your hashing power.  For example, if you look at AntPool and f2pool, you'll see they are finding the lion's share of the blocks because they are the biggest pools.  Sure, a pool can have a lucky streak and find more blocks than it should based on its hash rate.  Just like a pool can have a bad luck streak and find fewer blocks than it should.

Hi All,

   I'm just curious. Given that the fastest miner is currently contributing 1/5th~ of the total mining power, how come there not averaging 1/5th of the blocks found? I just woundered if it may technically be possible to divert found blocks to ones own wallet directly insted of back to the pool. Assuming you were on the the same block and midstate? Is this something that the pool monitors? I see that you monitor luck, but do you cross check blocks found against miner contribution?

   If any of the raw data is avaliable I'd love to see what could be done with it to see if blocks found roughly tally with individual miners total (life time) effort.

Thanks.
James.
