Eugen RochkoHm, 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?
watchtheriver@Gargron One is a pub / sub model with a persistence model that is likely K/V store, the other is a proof of work (and I believe) merkle tree backed store which can be sparse. In fact depending on internal decisions both can have sparse representations for some nodes
