Then it would be cheaper for them to run an append only SQL table. It also runs faster.
yeah but the point is that the blockchain technology doesn't have to be used for decentralization.
But would your "centralized blockchain" be cheaper, faster and more efficient than a SQL database? If the answer is no, then why run a blockchain?
Plus will it have a token to act as an incentive? Then what is the use of having one if it's centralized?

even in creating a cryptocurrency you can create a centralized one such as many altcoins that have already done it or the government issued cryptocurrencies such as Petro (Venezuelan crypto). being good/bad, efficient, cheaper or not is another argument though.
I believe you need to undertand the way Bitcoin is more and why it works.
again this is not an argument about whether it is good to do it or not, it is about the fact that it is being done.
as for centralized altcoins I can say it is a total bullshit because we already have them and all of them are pure crap.
as for government centralized altcoins I can't say because we only have one that started very recently. it doesn't seem like a good idea but we have to see how it turns out to be when other countries also do it.
as for other fields such as the SQL thing you ask, I have no idea because I have never seen any in action, I have only read news about them wanting to use it. and it doesn't seem different to me when it comes to speed. SQL database and blockchain are both a form of database but that is just my opinion.
existence of these things have nothing to do with bitcoin though. bitcoin is unique and exists and works and is growing in popularity because it is decentralized and secure. it fulfills a different purpose: a censorship resistance currency.
but centralized altcoins do exist and are popular. for example XRP is also popular because it fulfills a different purpose: a shitcoin to be pumped and dumped and people have made profit from it.
When you use the word "blockchain" how would you define it? It has lately become a buzzword that it might have lost its real meaning. Or does it have a real meaning?
I believe we should have a common ground in how to define what a blockchain is because if not, then there's nothing for us to talk about.
Does a centralized ledger like Ripple need XRP? Why?
they say "miners" validate transactions which is somewhat true since they either run a node themselves for their farm or connect to a pool that runs a Fully Verification Node that does it for them.
