Current difficulty missing

[PaulSff]

Although, it is a done thing to have current Difficulty number on the blockchain explorer, this parameter is missing.

It might, as well, be fetched from the Diffculty module storage:

• https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frpc.3dpass.org#/chainstate
• Method: Difficulty > currentDifficulty(): U256

Difficulty can also be decoded from the log (seal)
