The blockchain is only useful if you need decentralization across pseudo-anonymous actors.  This doesn&#x27;t apply to Big Finance.  The blockchain is also only useful with a large mining base, because security is achieved through having a large aggregate hashing power that cannot be overpowered by a bad actor.  That is why almost all Bitcoin competitors are worthless -- they have nowhere near the hashing power, and are thus nowhere near as secure.  The network effects here are huge.  Having multiple blockchains is like running multiple competing power distribution networks across the country operating at different voltages.  It makes more sense to standardize and have everything operate on one good one.  And that&#x27;s what Bitcoin already is.
