this target as a 256-bit big-endian integer, and valid blocks MUST NOT have
hashes larger than (above) the current target (in accordance with the Zcash

Miners SHOULD NOT submit work above this target.
Miners SHOULD NOT submit work above this target. Miners SHOULD validate their
solutions before submission (to avoid both unnecessary network traffic and
wasted miner time).
Servers SHOULD NOT accept submissions above this target.
Servers MUST NOT accept submissions above this target for jobs sent after this
message. Servers MAY accept submissions above this target for jobs sent before
this message, but MUST check them against the previous target.
When displaying the current target in the UI to users, miners MAY convert the
target to an integer difficulty as used in Bitcoin miners. When doing so, miners
SHOULD use ``powLimit`` (as defined in ``src/chainparams.cpp``) as the basis for
conversion.
