Fees and miner rewards are not needed at all for security at all since long term holders can simply invest in mining to secure the value of their stake. Isn't it enough that the protocol has a mechanism to secure value? Sure fees *might* be enough. But in the event that they are not, large holde

Oops, you are right. We need the bribe to be the output of the coinbase, but due to the maturity rule, it isn't really a bribe. Too bad coinbases cannot take other coinbase outputs as inputs to bypass the maturity rule. I guess that means the bribe has to be by leaving transactions in the mempoo
