But these two actually represent the same number.

for both of the above targets.
What (if anything) makes
bits a unique representation of the
In regular interactions with numbers, this kind of thing doesn't really matter, as a few leading zeros don't affect how we interpret the number. However, in Bitcoin, the
bits field is used as part of the hash of the block. Therefore, a different
bits representation would produce a different hash of the block.
