a blockchain. is just a block of data that is tethered (like a chain) to another block of data..

Some would argue that Satoshi didn't create the blockchain to group and chain data, but to prove a historical fact.
sorry but satoshi did infact design bitcoin where the blockheader data contained data from the previous header which made each block harder to manipulate the more blocks are created ontop of it. (more confirms=more trust)
the whole point of blockchains is that once created. its locked and the next block in the chain reinforces that lock, and so on and so on..
if you were to allow editable datasets where maybe you can change the data of something created last year.. you might aswell just have the list of unspents.. and just store some different method of verifying current balances of the unspents
some people have even thought of copying banks.. where there are clusters of people all grouped together.. like bank branches have sort codes/routing numbers to manage a certain group of bank customers balances.
where there is a hub that verifies movements and sends a batch file of "unspents" around the network so everyone has a copy of all the unspents verified by the cluster hub
that way its not a chain of data. but instead separate blocks of data not tethered to each other that can be updated at any given time
this should be something people can create as an altcoin if they want but in no way would/should it be proposed to ruin bitcoins blockchain security
I think there may be a misunderstanding.
Are you agreeing with my original post or disagreeing with it?
So you think Satoshi made the blockchain without needing something to prove first?
Or he needed something to prove and thus created the blockchain for that?
When I said he needed to prove a historical fact, I'm referring to things like previous block headers.
Technically, the Genesis block (and its blockheader) would be the first "historical fact".
