Transactions that cannot be part of block
Transactions that cannot be part of block Is it possible to have a "unlucky" transaction that can never be part of block? Meaning grouping it with other transactions never results in a valid block? [Edit] By not being in valid block, I meant no valid nonce is found with given target difficulty. It seems mathematically, this is possible and what happens to transaction (if there is no expirey) in this case? http://ift.tt/2BqwdbF
