In this episode of AWS TechChat, we take a journey into Amazon Managed Blockchain and Amazon Quantum Ledger Database (QLDB). I interview a blockchain specialist - Forrest, who help us deep dive into the depths of blockchain technologies and terminologies.

We start the show by setting foundations, diving into cryptocurrencies, tokenization, and smart contracts before walking through the difference between layer 1, layer 2, and sidechains.

We then pivot the discussion to private and public blockchain, Hyperledger as well as Ethereum. We close out this segment by answering some of the frequently asked questions - “Is there only one blockchain? Why do we need multiple blockchains?” 

We also discuss about blockchain versus databases and how to decide between Amazon Managed Blockchain and Amazon QLDB. 

Finally, we wrap up the show with some exciting use cases and share how you should start your blockchain journey.

Grip op Informatie: Vernietigen digitaal opgeslagen informatie

An operational data hub (ODH) is a pattern in data architecture that provides a central location and a standard protocol for operational systems to communicate about and share data among themselves. Operational systems post messages about data events (add, change, delete) and subscribe to messages of interest posted by other applications. The hub works to share data among applications without the clutter and chaos of point-to-point data feeds.
