If centralized, why not just restrict the API to make history immutable? Lol
When the largest cloud provider takes time to create and market a new product it's probably worth thinking about for more than a "lol".

#12So is “Quantum“ pure buzzword hype? Or is there a reasonable connection to the product?
Quantum just means something that can be counted or measured, usually in discrete amounts like whole number. Assuming the audits and entries are discrete and transactional, the word makes sense. But yeah, it just looks like they are trying to go for marketing buzzwords.

That doesn't give you the ability to cryptographically verify integrity of the database. Think git repository with pgp signature on every commit.
I think once centralized, there is inherently something wrong with blockchains. There is always chance of bait and switch, even though you trust amazon.

#14This is what I use protected git repo with a pgp signature for.

#16As they pointed out, this requires me to trust Amazon. But since that's the case, what's the point of it being auditable? Amazon can easily drop the last N transactions on your ledger and tell you the digest you provided was "not found".

In the context of computing technology, “quantum” is not the appropriate term, and I only agree it makes sense with the most generous interpretation of the term, whose meaning you describe finds itself mostly in certain physical theories. They could have used the word “discrete”, which is overwhelmingly more contextually accurate, if that’s what they mean.

AWS employee here. QLDB has been used internally at AWS for quite some time. We decided to turn our internal service into an external facing product because we saw a demand for a ledger system with central authority. Many people were trying to force Blockchain to accomplish this, while we already had an internal ledger solution that is far more scalable while still being cryptographically verifiable.

What throughput do you get with that?

Eh, it's a branding thing. I doubt many customers are confused.
