When it comes to Bitcoin, the current difficulty is a measure of how difficult it is to find a hash that is below a given Target. The Bitcoin network has a global block difficulty.

Valid blocks must have a hash below this Target. Mining pools also have a pool-specific share difficulty setting a lower limit for shares.

The Bitcoin network has a global block difficulty. Valid blocks must have a hash below this Target.

If they don’t, they’re rejected by the network as invalid. The higher the Target, the more difficult it is to generate a valid block.

The current difficulty is 7,929,942,118,209 (or about 7.9 quadrillion). This is based on the fact that there have been about 14 billion hashes attempted since the last difficulty adjustment block on February 11, 2020.

The difficulty adjusts every 2,016 blocks (about two weeks), so if the rate of hashing power increases or decreases, the difficulty will adjust accordingly. If the hashing power increases, the difficulty will go up; if it decreases, the difficulty will go down.

The current difficulty is high because there has been an influx of new miners trying to cash in on the Bitcoin price boom. This has led to higher competition and hence higher Hashrates, which in turn has led to a higher difficulty.

However, with more miners comes more hashing power and hence more security for the Bitcoin network. So even though the current difficulty is high, it’s still possible to profitably mine for Bitcoins.
