New current RieCoin record was in block 289872 in early July, with 679 digits!
However it's not enough for a new World Record, as the bar was raised to 700 digits in January
Actually, I have raised the bar even further, 751 digits on the 8th of August:
http://anthony.d.forbes.googlepages.com/ktuplets.htmTo beat this with the present fork of Riecoin, you need a superblock with difficulty around 2495, corresponding to a general difficulty of 1706 or above. (Apparently, the superblock difficulty is about 1.462 times the normal difficulty.)
It has been a year or so since the difficulty was in the 1700s but both difficulty and exchange rate made some interesting jumps in June and July this year, so who knows
But I have to admit, considering that the record 6-tuplet a year ago was 593 digits, the Riecoin Hall of Fame is really impressive!
