> The network reaches consensus on the state of any particular chain by validating the signatures Ok I can see that. It's the distributed consensus problem in a centralized setting. It still feels strange to call that a blockchain but maybe it can be qualified like "centralized blockchain" (which questions the need for such a structure to begin with).

I’ve seen centralized blockchains used to great effect in ledger contexts where the chain is not synced, but references (hashes) of the chain are shared externally (I.e. transaction ids). If an external auditor has a set of transaction ids that have been communicated externally, they can later audit the centralized chain and prove it has not been tampered with without having to have the full log of blocks.
