0.000 HBDAmazon doubling down on blockchain technology
 Amazon announced managed blockchain services a while ago that is based on Ethereum using the open-source Hyperledger Fabric. Amazon recently announced a new product called Quantum Ledger Database (QLDB). <center></center> While Amazon calls it Quantum, there is nothing Quantum about it. It is really interesting nonetheless. QLDB offers a SQL-like database interface while offering immutability and verifiability of blockchain technology. The key focus of QLDB is to offer the complete history of all transactions by removing the ability to update and delete anything in the transaction history. Want to delete or change a record? All previous data will be available and can be verified at any point of time. QLDB runs on AWS and is not distributed and decentralized like other blockchain technologies. This is where QLDB veers from the goals of most blockchain projects. Using QLDB is nearly as simple as using a cloud SQL database and can be interacted with using similar interfaces. QLDB targets banking, government, and insurance type applications where verifiable transaction history and proof transactions have not been modified is critical. Amazon aims to eliminate the need to complex and time-consuming custom audit functionality. True to other Amazon Web Services, QLDB can a lot easier than building infrastructure and development but does get expensive when not properly configured. # Sample Pricing https://i.imgur.com/0cHrgUo.png Using QLDB requires no hardware and scales to what you need. It is exciting to see large organizations embrace blockchain technology and help improve awareness and adoption.
