Hi Austpool,

    The warning message is harmless right now.
    It is the result of a controlled test of our Mincoin Core v0.14.3 code and the decentralized MincoinPool v17.1 code which will soon be officially released.

    Yesterday, we observed an extraordinarily long target spacing of > 90 minutes for a block.
    In an attempt to get the chain moving, some rentals at MiningRigRentals were made and MincoinPool nodes were linked between Asia, North America and Europe to help stabilize target spacing to 60 seconds.

    The unknown rules refer to the new wallet code signalling for our BIP 9 deployment of Segregated Witness (SegWit).
    In order for that to cause a potential problem, 19152 of 20160 blocks ( 95% ) would need to be mined by the new software during a two-week timespan.

    This test has been running for less than 24-hours therefore it is of no consequence.

    Thanks for being observant and asking the important questions!
