Work out blockchain hash difficulty instantly with clear inputs, formula shown and shareable results.
Bitcoin difficulty is defined so that the expected number of hashes per block is difficulty multiplied by 2^32. Dividing by your hash rate gives expected solo mining time, and dividing by the target block interval recovers the implied network hash rate. Your share of that total is also your expected share of blocks, which is exactly what pool payouts distribute.
Difficulty relationship
expected hashes = difficulty x 2^32; time to block = expected hashes / your hash rate; network hash rate = expected hashes / target block time
Difficulty 1 corresponds to a target where roughly one in 2^32 hashes succeeds. Difficulty scales that threshold linearly, so expected work is difficulty times 2^32.
No. It is a Poisson process, so the time is exponentially distributed. The expected value is a mean, and actual intervals vary enormously around it.
