> The overhead from the consensus algorithm serves no purpose and will only limit throughput of the whole system, and appears to be there here no reason other than apparently cargo culting public blockchain technology which is not designed for this use case. I may be behind on Libra news, but my understanding was that the permissioned blockchain governance model would only exist during the bootstrapping phase to launch Libra and would eventually evolve into a public blockchain once it reaches some arbitrary point of stability. If that is still the case, then wouldn't Byzantine fault tolerance be required from the get-go, assuming Facebook wants to avoid a hard fork of Libra?
