Hm, I actually don't know if there's a word for it, but I was talking about blockchains with someone, and one of my points is that the blockchain is decentralized, but also kind of isn't, in the sense that there is only one ledger that everyone shares. This as a counterpoint to a federated system like Mastodon, where every server can exist independently of others. Is there a word for this?
Actually maybe my issue is that I consider "distributed" to be a subset of "decentralized", when maybe they are separate properties, in which case you could say the blockchain is distributed but centralized..?

@Gargron

Not sure the #blockchain necessarily is (must be?) centralised in all possible implementations.

@ZeniorXV @Gargron side note; can we all please get into the habit of saying #blockchains, not "the blockchain"? The latter can tend to confuse newbies into thinking there's only one blockchain, and that all blockchain startups are using it, the same way there's only one internet, and all internet startups are using it.
@ZeniorXV @Gargron I also prefer "decentralised" as a generic term for "not centralised", with federated and distributed as subcategories. I think the term you're looking for is "unified" for a blockchain ledger, and maybe "segmented" for the fediverse as a database?
@ZeniorXV @Gargron autocorrect tried to change "segmented" to "demented". Freudian algorithm? ;-)
