Fortunately enough, the retail giant Amazon realizes the potential needs of all its customers and developed various offerings that would allow those on each side of the debate to reap the benefits of the products.  Amazon Web Services (AWS), which handled the development of the solutions, discovered that some customers did want there to be an immutable and verifiable record of all transactions or changes that have taken place on a platform but don’t mind having a centralized blockchain in place so that it can happen. For these types of customers, they developed the Amazon Quantum Ledger Database to provide them with a ledger they can access but one that is ultimately controlled by a single company.
