Topic says it all, all these dime a dozen block chains that are coming out that everyone are creating, will they need computing power/hash rate to secure them from 51% attack like bitcoin does, or am i missing something??

My understanding is that a majority of them, if not all, will not be secured in any way that Bitcoin does.
They are just private computers/nodes storing/transacting within their own private blockchains/ledgers.
It is pretty much pointless IMO, but they haven't figured that part out yet.
