Title: Does OP_NOP have any use cases?
Post by: Taras on January 09, 2015, 06:15:57 AM
Or is it made to be completely arbitrary and useless? ???

OP_NOP can allow extra embedded information, but you must mine the block yourself since it's non-standard, making it about as useful as DUCK_FART. ETA: Maybe legitimate use cases could be thought up back when mining a block by yourself wasn't a big deal.
