Thread necromancy. Pretty much all of those are really low-scoring penny spam, legit free transactions should still get into blocks quick enough thanks to dPriority.
Why are low BTC transactions considered illegitimate or spam?
Lastly, algorithm cryptopp_asm32 consistently generates proof of work that gets rejected with a "Boo" message.
I'm seeing the same problem. I've had many rejects and no successes using cryptopp_asm32 and have had many successes and very few rejects using the default algorithm. I'm using version 0.3.1. Has anyone had any success using cryptopp_asm32?
