You could do that with any widely-adopted standard. No blockchain required. Remember that even IBM at their late-1980s juggernaut status couldn't put the genie of the ISA bus back in the bottle.

I think the trick to lasting open standards is to provide only a MVP ecosystem at launch. No one vendor is strong enough to close the platform behind them. Again, like the IBM PC, their product both needed and spawned a galaxy of add-on and compatible products, providing enough of a force to protect the open standard.
