Amazon Enters Blockchain Market With Cloud-Computing Services (bloomberg.com)
Amazon.com is jumping on the blockchain wave with new cloud services that help customers build the technology needed to record transactions. From a report: Amazon Web Services Chief Executive Officer Andy Jassy on Wednesday announced Amazon Managed Blockchain, a new service underpinning blockchain networks that record millions of transactions. The company spent the past year studying the needs of customers interested in blockchain solutions before creating the new products, Jassy said.
The service can be used to manage peer-to-peer payments, process loans and help businesses transact with distributors and suppliers, Jassy said. AWS announced a string of other new or updated cloud offerings, seeking to maintain its lead in the market for internet-based computing. The company also announced a new service called Amazon Quantum Ledger Database or QLDB, which is a fully managed ledger database with a central trusted authority. The service, which is launching into preview today, offers an append-only, immutable journal that tracks the history of all changes, Amazon said. And all the changes are cryptographically chained and verifiable.

Doesn't this run contrary to one of the benefits of a blockchain? That being it's distributed, decentralized nature. The ledger isn't maintained by one entity that can fiddle with it. Or be arm-twisted by authorities to back out transactions that they don't like.
Have gnu, will travel.
Enterprises will need blockchain solutions. Good to see AWS joining the fray, though much of their offering is centralized.
However they took their time given where players like Microsoft and IBM are doing.

Dissociated Press (DP) — FOR IMMEDIATE RELEASE
Physicists identify new fundamental particle
May herald a new particle family and restructuring of the Standard Model
Geneva, Switzerland — August 2018
Keywords: hypino, shinyon, blockchain
High energy particle physicists at the CERN (Conseil Européen pour la Recherche Nullité) facility have confirmed the existence of the long-conjectured hypino (hy-PEE-no). It is thought to be the first member of a new class of particles known as shinyons (SHY-nee-ons), distinct from bosons and fermions.
Unlike other subatomic particles, hypinos carry no charge, and have neither rest nor relativistic mass. Their only defining quantum property is spin. Hypinos are thought to be the fundamental unit of marketing hyperbole. To date, hypinos are the only known members of the proposed class of shinyons, which are of especial interest to tech investors and holders of the MBA degree. Dr. Martin Waugh, of the Institute for Advanced Squander, further posits that the hypino may be the carrier of the so-called “weak-minded force”, a mutual repulsion between fools and their money. It is theorized that, upon sufficiently accelerated spin, hypinos transform into super-excited hyperinos, detectable only by Chief Information Officers.
The discovery of the hypino is recounted by Drs. Robert Crawford and Robert Jensen as follows:
“It was a Friday afternoon, and we and our colleagues were returning from a long lunch. Maintenance on the Large Hadron Collider (LHC) was scheduled to start Saturday morning, and the apparatus would be unavailable for two months. We were in a ‘what the hell’ kind of mood, so we thought we'd take a fantasy shot, just for grins and giggles.
“We had a few leftover Higgs Bosons from 2012 on the shelf, so our lowly lab technician, Garth Dennis, breech-loaded them into the beast , set up a blockchain for the target, positioned the extremely sensitive Swindleometer at the intended point of collision, energized the superconducting electromagnets, and let it rip. Upon collision, the blockchain shattered into a shower of the elusive hypinos. Examination of the debris field revealed that the blockchain and all of our cash were gone! Apparently the hypinos were entangled with our funding.”
There may be natural sources of hypinos. The strongest natural emitters appear to be located in Redmond, Washington, and Armonk, New York.
The term 'Quantum' in QLDB appears to be a marketing term and not related to post-quantum addressing schemes like XMSS/WOTS+.
That sort of "quantum" blockchain deals with the theoretical attacks on ECDSA addressing schemes; examples: Mochimo and QRL.
Amazon's appears to be an append-only journaling system based on SHA256. It's unclear from the documentation whether it just hashes each transaction and maintains a verifiable/uninterruptable chain of hashes, or whether it also injects a Proof-of-Work style iteration based on nonces to make "reconstructing" the blockchain unfeasible.
So dangerous,
Amazon is already eclipsing all other companies
but having it's own monetary system is just insane
one worldwide money, accounting, tax, trading
Go well
Maybe not, but crypto currency is the only application of Blockchain that makes sense.
In what other industry is it desirable to have a distributed ledger?

and they won't let the U.S. government do it either, right?

Supply chain and inventory management come to mind...
Show me on the 1st Amendment bobblehead where the moderator touched you...
You're missing the point. It's about recording something that cannot be altered and no-one involved has to trust the other parties as to the veracity.
Anything that needs such properties can perhaps benefit from Blockchain. Someone mentioned supply chains - lots of companies (often rivals) coordinating their activities.
A lot of work involves using a lawyer as a trusted third party. All that can vanish if all the parties can mathematically prove what was agreed and no-one could have altered it.
You would want a 3rd party to share records of your supply chain and inventory management? Because that's the whole point of blockchain... that's what a distributed ledger means. The whole point of blockchain and the distributed ledger is to non-centrally authenticate the veracity of records.... which is why it is FUCKING INSANE that banks and factories are interested in this. Are banks, farms, and factories going to distribute their internal info to third parties? If not, it's not blockchain. Blockchain is also encryption.... but if it's entirely INTERNAL, you can rewrite history, as no one is checking in real-time, and there is ZERO FUCKING POINT.

You don't need to recheck the entire chain. Only blocks after the last trusted hash. Any block chain that does not contain the last trusted hash cannot be trusted at all.
