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.
Traditionally, it represents a hash where the leading 32 bits are zero and the rest are one this is known as "pool difficulty" or "pdiff". The Bitcoin protocol represents targets as a custom floating point type with limited precision; as a result, Bitcoin clients often approximate difficulty based on this this is known as "bdiff".
Each block stores a packed representation called "Bits" for its actual hexadecimal target. The target can be derived from it via a predefined formula. For example, if the packed target in the block is 0x1bcb stored in little-endian order: cb 04 04 1b , the hexadecimal target is.
Note that this packed format contains a sign bit in the 24th bit, and for example the negation of the above target would be 0x1b 8 cb in packed format. Since targets are never negative in practice, however, this means the largest legal value for the lower 24 bits is 0x7fffff. Additionally, 0x is the smallest legal value for the lower 24 bits since targets are always stored with the lowest possible exponent.
The highest possible target difficulty 1 is defined as 0x1d00ffff, which gives us a hex target of. It should be noted that pooled mining often uses non-truncated targets, which puts "pool difficulty 1" at. It uses a modified Taylor series for the logarithm you can see tutorials on flipcode and wikipedia and relies on logs to transform the difficulty calculation:.
This particular function lets you scale by a power of two almost for free, by directly adjusting the exponent on the floating point number. Thus, the difficulty calculation gets reduced to a couple integer arithmetic steps, single floating point divide, and a single scale-by-power-of There is no minimum target. The difficulty is adjusted every blocks based on the time it took to find the previous blocks.
At the desired rate of one block each 10 minutes, blocks would take exactly two weeks to find.
