Has it been confirmed that these are valid prime chains? If I'm not mistaken (please correct me if I am), primecoin only checks for probable primality.
Indeed. Nevertheless, great results for only 3 days of mining!

You are quite right. However, the first probable prime still fails.

Woot! Not sure it's me, I sent some stuff I mined on windows to my linux wallet and then destroyed the windows wallet Anyway, very cool

does this mean it's not actually generating valid primes?

Both fail on #9 in my Block Crawler: Block 2044Block 5355Of course that is dependent of my code for generating the chain being correct.

Good job Petrified! What primality test you are testing on your crawler?




Petr1fied


July 10, 2013, 03:13:35 PM 

It's a php function gmp_prob_prime which is part of the GMP (GNU Multiple Precision) extension. It uses MillerRabin's probabilistic test to check if a number is a prime.

Is block 2616's TWN8 chain with origin length of 111 digits interesting? edit: Realized that no it wouldn't sit in the top 20 of 'BiTwin Records two links' Bitwin chain records only count even lengths. So we are waiting for the first TWN10 block (which is the bitwin of 4 links)

This is AWESOME! Nice work Sunny, glad to have something new and substantial to mine. I love CPU only and hope it stays that way for awhile.
