In bitcoin, diffculty = 1 means 2^32 times hash, the target is 00000000FFFF0000000000000000000000000000000000000000000000000000. But in zcash I did't find this relationship.
I got it, in zcash, difficulty 1 means 2 ^ 13 times hash. the target is 0x0007FFFF00000000000000000000000000000000000000000000000000000000
In Zcash the difficulty Algorithm is not like any other coin (except zcash forks, of course) it's a modified version of Digishield V3, you can read more here: https://github.com/zcash/zcash/issues/147
Thanks for your reply.
