So "unaware assumptions" it is then.
I'm sorry if you perceive that as snarky (and not everyone that disagrees is a troll btw), but to me, decentralized authority is what some people perceive an important (if not zealous) use case. It is not the defining property of blockchain. There are many companies that are building distributed ledger with centralized authority. You may disagree with that use case. I feel it's lack of self awareness to think a valid and clearly implemented use case is somehow antithetical to a simple neutral well defined technology.
The fundamental innovation of the bitcoin protocol is how it made the blockchain, a traditionally centralized data structure invented in the early 1990s, a distributed append-only database using PoW consensus. It's incredibly inefficient, its unimaginable inefficiency is there to buy trust in a trustless peer-to-peer network. You're basically forcing every writer to cut down a pound of their own computational flesh to write to the database. How can this be necessary or useful in a trusted setting? why can you not rely on trust or traditional register-and-authenticate to write to the database?
You're either using PoW consensus or you're not. If you're, you're not a central authority (unless the blockchain is somehow not an authoritative state and you're simply using it as a fancy bulletin board), if you're not, then whatever you're doing is different from what everbody else have been calling 'blockchain' since 13 years and you're just inviting confusion by calling it that.
I'm an outsider laughing at the whole Blockchain brouhaha, have zero horse in any race. I'm just amused endlessly how any given individual strongly believes their perspective is the only valid one and all others are simply "wrong", and heretics to the one true religion I mean bitcoin I mean blockchain I mean Crypto currency (Note how people are switching which one we are talking about in the thread. Due to various assumptions of equivalence ). Everything in this thread has firmed up my perspective.
No, we're saying that modern usage of "blockchain", dating back 13 years, is specifically about distributed trustless append-only ledgers, which is only useful for distributed authoritative state. Crypto currencies just happen to be a really good application for distributed authoritative state. You can do trusty applications with trustless ledgers, but that would be pointless and needlessly wasteful. You can do a centralized 1990s blockchain, but calling it 'blockchain', though technically true, just smells of marketing hype.

Snark.

People on HN probably don't need to be reminded by the entry level 101 stuff about the difference between bitcoin and the blockchain, so your point is just trivial hair splitting. Bitcoin is a special case of crypto currencies, which is enabled by PoW driven blockchains, which without PoW are just boring old data structures. People switch between them because they are a natural fit that exist for and because of each other, and anyone of them alone either don't make any sense or make little sense.
>Everything in this thread has firmed up my perspective.
I don't see why you're so proud that you have learned nothing, but anything that makes you happy I guess.
I also do not believe blockchain, bitcoin, and cryptocurrency are actually synonyms and easily interchangeable, in knowledgeable or not knowledgeable audiences. I do think they're deemed interchangeable for some subset of people, per my initial point, who believe them to be trivially synonymous; and who cannot themselves be educated or be opened minded enough or escape internal context to see how anybody else can possibly have a different perspective. Here, too, we have failed to reach each other, and I suppose to neither of our surprise either.
No it’s not. A blockchain can be used in a way that only specific central authorities can add to it. https://en.wikipedia.org/wiki/Blockchain#Private_blockchains
The fact a central bank is a "human institution" is irrelevant. The fact blockchain is a "technology" is also in itself irrelevant. The point is that each concept necessitates characteristics that are irreconcilable. Most importantly a central bank can not function without central authority. The defining property of the blockchain is the decentralization of authority. Authority can not be simultaneously centralized and decentralized, and so the blockchain and the central bank are antithetical concepts.
