Now you can use QuarkChain explorer's PoSW page to mine root chain with lower difficulty if you stake enough QKC. Following is a quick start.

To begin with, root chain miners need to meet two requirements to be able to mine with PoSW in effect:

1. having enough stakes (1,000,000 QKC for 1 block allocation, with maximum allocation size 512);
2. signing the submitted root block work with the correct signer specified by the root chain staking system contract (by default, it's the miner him/herself).

With this in mind, go to the explorer's PoSW page, you should find your staking information showing locking status, staking amount and corresponding mineable block allocation, signer and withdrawable time (if unlocked) right in the middle of the page. Their meanings are straightforward, with following notes:

1. Locking status: stakes are effective only during LOCKED status (which is the default status). It will become UNLOCKED if you send an unlocking transaction.
