I'm getting this repeatedly in the console:

<br />2015-04-03 01:37:20.488 INFO generated signature: c7d00735f03c273a2a6efcc6<br />2015-04-03 01:37:20.489 INFO&nbsp; &nbsp; hit: 0x779e75ffb8cdb4 (org.nem.nis.p.vx a)<br />2015-04-03 01:37:20.489 INFO target: 0x5945859bbe09 (org.nem.nis.p.vx a)<br />2015-04-03 01:37:20.490 INFO difficulty: 55% (org.nem.nis.p.vx a)<br />

over and over, and the difficulty is rising like 1% every 2-3 minutes. just wondering if I'm in the main chain
