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 ...

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. ...

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 ...

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

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 ...

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