### How much CPU power to mine 1 coin a day?

This answer will attempt to answer the question at multiple levels, as follows: Section I explains the basics of how to calculate this yourself. Section II provides updated calculations based on ...

### Hashrate correlation by time of day

The daily variance appears to be limited to about 10% of the hashrate. Two possible explanations: A system administrator mines Monero at night when computers would otherwise be idle A system ...

### ccminer-cryptonight reports insanely high hashrate on nvidia gpu

It looks like your hash-rate is calculated in the following code: hashes_done = 0; gettimeofday(&tv_start, NULL); /* scan nonces for a proof-of-work hash */ rc = scanhash_cryptonight(thr_id, ...

### Hash rate required to effectively mine an average of 1 block a day?

Currently the network hashrate is approximately 22.9 MH/s. There are about 30 blocks per hour and 720 blocks per day. On average to find one block per day you would need 1/720 of the current network ...

### Hashrate correlation by time of day

In addition to the (very likely) reasons given by Big Things, there is also the distinct possibility that something in the difficulty adjustment algorithm is causing this. It could be the way we're ...

### At what stage is the Monero mining race at right now?

Right now Wolf's OpenCL XMR Miner for AMD GPUs (open source) and Claymore CryptoNote GPU Miner (proprietary) are probably the most efficient. It is believed that Monero is still quite far away from ...

### Monero private key collision

Well, private spend keys are 64 character hex strings, see here: https://moneroaddress.org That will give you around 1e77 possible private keys. If n is the number of possible private keys, and you ...

### How much money would be required to cloud mine 51% of the network hash rate?

Assuming a current hashrate of 21.1 MH/s, an attacker would need a bit more than 21.1 MH/s to perform a 51% attack. This assumes that doubling the hashrate for a day doesn't drive miners out. ...

### How decentralized is Monero mining?

There are at least 13 pools but likely more due to private and unkown pools Not yet, but there has been some interest in the idea It does not exist for Monero but it would be a nice little project ...

### How much CPU power to mine 1 coin a day?

According to https://www.cryptocompare.com/mining/calculator/xmr you need 2910 H/s at the moment to mine 1 XMR per day. Here's a Google doc with a comparison of various hardware (CPU and GPU) for ...

### At what stage is the Monero mining race at right now?

Currently network hashrates are near historically high levels. How much further hash rate moves up in the future depends heavily on mining profitability based on current XMR prices and coinbase reward....

### After major coin issuance, what must the minimum XMR price be to incentivize network security?

This is kind of a subjective question. Currently the block reward is ~ 10.4 XMR per block or 5.2 XMR per minute. When the tail emission kicks in, the block reward will be 0.6 XMR per block (assuming 2 ...

### Can any CryptoNote coins be merge mined?

The Monero community almost unanimously voted against merged mining choosing instead to stand on its own and avoid indirectly supporting another CryptoNote coin, BCN that was 80% premined.. Actually ...

### Resource to see mining distribution

https://monerohash.com/#network is a pretty good visualisation of the state of Monero mining. It also has some basic stats on nodes, and the blocks the monerohash pool has found.

### How much money would be required to cloud mine 51% of the network hash rate?

I think on AWS the most economical way to mine is with is a g2.2xlarge which costs \$0.2017 per hour at spot price right now. I believe you can get on average around 1 kH/s with the GPU and CPU ...

### How can I calculate the Monero network hashrate?

The hash rate can only be estimated from the difficulty, which is itself adjusted up and down based on how fast blocks are found compared to the 120 second target. This estimation is the difficulty (...

### How is the block hash encoded?

You cannot compute a block's difficulty from its hash. The hash is a Keccak hash. A different hash using Cryptonight is used for PoW purposes, but this isn't the block hash. It is often called the ...

### How to achieve uniform hash rate

Pools do not know your hash rate, they can only estimate it based on the shares you submit. Since finding those shares is in inherently random process, you will sometimes have lucky breaks, and ...

### Why is the Monero hash rate so low after the v7 fork compared to other Monero forks?

When Monero forked to v7, it changed its proof of work algorithm. While it previously used Cryptonight, it now uses a slight variant (technically, variant 1) of Cryptonight, which should be typically ...

### What is a mining round?

I believe this refers to hashes - it does 39 hashes for you and 1 hash for the developer, regardless of whether the hashes are valid or not. As Claymore is closed source, we can't easily verify this, ...

### Monero private key collision

To answer the question for Zcash, spending keys are 252 bits (all of which are valid). There's no practical difference between 252 and 256 bits in terms of the probability of collision for a properly ...

### How can I see my hash rate?

The log file is ~/.bitmonero/bitmonero.log. On Windows, it is somewhere else which someone who knows will edit here soon. The status command reports your hash rate. If you're running a detached ...

### Hashrate correlation by time of day

This could also be market driven. The price of Monero has been swinging whole % points daily. It's possible someone is mining to pick up some extra XMR to dump for profits.

### Monero private key collision

The likelihood of a collision is theoretically 1 in 2^256 which is a number with 78 digits. It's the likelihood of winning the lottery 7 times in a row, or something along those lines. Unless, of ...

### What happens as monero network hash rate decreases

Value of a coin and hash rate goes hand in hand. If value of coin decrease, then miners will have less reward for their mining and will rather go mine some other more profitable coin. So if a coin ...

### Why does my pool say my hashrate is lower than what my computer reports locally?

The hashrate that is reported by the pool is an average over some time period - for example the original core pool implementation uses a window of 10 minutes (600 seconds) to compute the average. ...

### Why low hash rates doing SHA/CryptoNight algorithm?

You cannot compare hash-rates for SHA and CryptoNight as they have different characteristics. CryptoNight requires 2MB of processor cache per thread and if you don't have that, the hashing will be ...
