Now the 12 chain records are rolling in Grin

Code:

New World Record!
Block 74722, Chain 2CC0c (12 primes), 97 digits
Previous record: 62 digits

Does that show up in debug.log?

is that that only way to check on linux?

Not in debug.log. That output is from the Python program I pasted a couple posts back. The code should work cross-platform, since it's Python.
