Amazon has recently provided some more information about two of its blockchain-related projects. They are the Amazon Managed Blockchain and the Amazon Quantum Ledger Database.
The preview of these new products points out that they are still in a very early phase, but that Amazon is getting consistently more interested in the blockchain technology and that it plans on using it more and more in the near future.
During the presentation, two aspects were especially showcased: the immutability and the verifiability of the blockchain technology. People can use it to enter immutable records and easily verify them in a decentralized manner. This trust aspect is why the company is so interested. Several other companies can use this technology for many purposes.
One caveat of the presentation is that Amazon keeps using the term “quantum ledger” while quantum technology is still not here, which means that it is more of a buzzword than anything else.
The so-called quantum product (see here) was created for cases in which a complete blockchain is not needed, only parts of it. In this case, some of the immutable technology can be used, but in a more centralized way, so that a single entity controls the data. What there is of something really new here is that the database allows for inserts, but not for deleting information.
Amazon Managed Blockchain, (see here) on the other hand, is the real thing. A complete core blockchain product that can be used by companies that are interested in private blockchains. This platform is set to initially have support for Ethereum and the Hyperledger Fabric technology. While Hyperledger is for companies that want to create a private network, Ethereum is better for creating open ones.
