AWS and Blockchain
Tim didn&#x27;t mention a contemporary sibling tech at AWS which should not be thrown out with the bathwater: private (centralized), immutable, signed ledgers. Their version is called QLDB and does have concrete applications where you need an provable audit trail of a stream of transactions with search and index on top. I was on a team at a fintech closely engaged with AWS to prototype a money movement system using that as a central ledger. There&#x27;s an open source one with similar properties on GH somewhere, also.<p>It&#x27;s not sexy like blockchain so it seems marketing had to slip in some Quantum to bump the buzzword sex count.<p>If financial industry regulators were serious about catching laundering or book cooking, they would demand this kind of tech as a foundation of compliance reporting.
