Their big reinvent conference is this week, they're making a series of product announcements.

Can you (have you?) say anything more publicly? Would be interested to know more.
Git and QLDB both use the Merkle tree concept to prove that history hasn't been edited. The GPG signing proves new events are coming from a trusted person or computer.
Thanks. (I'm actually aware of the mechanisms involved and have implemented something similar in the past, although with a rather different set of tradeoffs.)
My main interested was in use cases and the details of the integration with git.

I don't think the parent was suggesting there be a single trusted third party.

This is overall great. QLDB is necessary for a lot of things, and it will be useful for a lot of the stupid 'blockchain' projects to be displaced by a better technical solution.
Now cryptocurrencies and blockchains are exactly what they are: a decentralized version of this. I believe that decentralization has some use cases that are extremely important. Now it can stand on its own, without being conflated with verifiable ledgers.

Using a private blockchain has the same issue of trusting a third party. As soon as someone has control of who can write to the ledger, you need to trust them, period.

Your data modelling has to be GDPR compliant not your database.
How do you delete user data from an immutable store? You get into cryptography at that point and then some edge cases make it not so simple.
The point is that you never put it in an immutable store in the first place if there's a chance that it would need to be removed later.
Re: Amazon Quantum Ledger Database
#110I'm pretty sure this is what most people actually want when they say they want a blockchain, they just don't know it yet. It's got all the useful database features with none of the "well uh let's distribute it over people's computers and let people mine coins to support it" complexity, which adds nothing to 99% of usecases besides silly ICO potential.

The Walmart thing is just PR. I doubt it's anything beyond a pilot and it's probably just a permissioned ledger, much like QLDB.
