Bitcoin&#x27;s problem is not that it has a single reference implementation. It can be forked, at least in a technical sense.<p>Bitcoin&#x27;s problem is that a tiny number of people managed to convince key players that they are irreplaceable &quot;experts&quot;, despite having repeatedly proven that they aren&#x27;t experts at all (go check out the Bitcoin forums today to see the wailing of users due to the giant tx backlog).<p>This isn&#x27;t something Ethereum has any solution for. If Vitalik stepped back and after a few years some random developers had managed to manipulate the Ethereum community into doing something stupid, having 3 implementations instead of 1 wouldn&#x27;t save them.
