Yes, I do not believe that Non-PoW coins are technically using the "blockchain", IMO.
(Though it doesn't matter now, since it will take a hundred years before the term is corrected, if it is.)
I think, in theory, it should be a new chain type, even though the parts are mostly the same.
For example, a plane and car have roughly the same parts and functions except certain fundamental parts.
Now the car was invented first and then the plane, but we do not call planes "cars or flying cars" or such.
Yet, with cryptocurrency currently, we say each different proof of blank system are all using the "blockchain".
That would mean we are all saying, "my car has an engine" and "my plane has an engine", but that doesn't
describe what the intent or purpose of the engine is for that technology. It doesn't really make sense for
identification or understanding. Each different proof of blank system should have a different chain name
that distinguishes between the chains security/work mechanism.
For example:
PoW - blockchain (since it was first, otherwise it would be workchain) ?sha256hashchain?
PoS - stakechain
PoB - burnchain
But, if we use the term "blockchain" as just a superficial term, we shouldn't continue to say that Bitcoin invented
the "blockchain" because then it did not, but invented the proof of work chain, which was the first "blockchain"
until PoS was created, and then they co-opted the term, and now all other proof systems co-opted the term, so
everything is a blockchain now, and even recently, private centralized non-proof ledgers can also be a
blockchain if they have a block here and there that can chain here and there.
I think the term has be watered down to the point of irrelevance.
you suggest because trains invented the first combustion engine. we should not call car 'engines' engines. simply because an engine doesnt define the difference between what a car, train or plane is used for.
blockchain is not the big special endpoint technology. it is just a small element.
what i am seeing is if we emphasise PoW as a pre-requisite then we are simply kissing Adam Backs ass for his 1997 'hashcash' more so then actually recognizing bitcoin as a combination of 10+ technology/concepts that uniquely came together.
oops did i forget to mention PoW came before bitcoin/blockchain, sorry thought that was common history knowledge
merging adams backs PoW with blockchain. is not defining anything. but shifting definitions to kiss someones ass
I don't think trains invented the first combustion engine, I think it was placed on a "train".
So thus it was a "combustion engine locomotive or combustion engine train".
In this sense, due to the technology back then, they used the engine term to define the type of train.
Now that engines have been placed into multiple different systems, ex cars, trains planes, bikes, etc,
the engine part is dropped due to it being "obvious" to us. Kind of like when people said "motorized
cart", to distinguish from a regular "cart". The terms existed because it was a place holder for something
that was new. Eventually it was fleshed out and given a specific name.
Blockchain was the layman term for something that was new and not fully understood.
It was used to get average people to understand the Bitcoin system in a visual way.
You are saying you don't like my definition or interpretation that is fine, but I don't understand why you are
attacking me or accusing me of kissing Adam Back's ass. I don't know him, never talked to him, never heard
of anyone from Bitcoin or anything crypto prior to 2013. There is no reason for it. I am just voicing my opinion
on the definition of blockchain and what I think is proper based on my reasoning. Only time will tell whether I
am correct or wrong, but I still stand by it.
I believe that if we use the sterilized version of blockchain, then it doesn't really mean anything.
It could be anything, even the very financial systems that Satoshi created Bitcoin to be against.
IMO, blockchain was and should be a workchain, and in theory would then go into a subgroup
for different workchain types, like SHA256 and etc.
