Why is explorers shows different difficulty values? Just take a random block for example, for block 506068, blockchain.info shows difficulty as 2,603,077,300,218.59, while blockcypher shows 392,962,374, do the explorers use a different way to calculate them, why are they different?
Blockcypher is not showing difficulty but difficulty target. You can see blockchain.info also show this under 'bits'.
