Amazon has announced two new blockchain-related services: Amazon Managed Blockchain and Amazon Quantum Ledger Database (QLDB). The company shared this in a press release.

QLDB is a ledger database that provides a transparent, cryptographically verifiable, and immutable log of transactions. A central trusted authority oversees the transaction log. Any changes to the database are recorded on the blockchain. The new product can also automatically scale and execute two to three times more transactions than existing products.

Andy Jassy, CEO of Amazon Web Services (AWS), said, “The product will be really scalable. You will have a much more flexible and robust set of APIs [application program interfaces] to make any kind of changes or adjustments to the ledger databases.”

Amazon’s product website adds: “With QLDB, your data’s change history is immutable – it cannot be altered or deleted. Using cryptography, you can easily verify that there have been no unintended modifications to your application’s data.”

AWS Blockchain Features

As for AWS’ Managed Blockchain product, Amazon announced it can work alongside QLDB. It lets users adjust and manage a scalable blockchain network. The product also automatically scales based on the needs of specific applications. It can manage certificates, track metrics such as storage, memory, and computer usage, and invite new users to the network.

It will be recalled that early this month, Amazon won two patents related to methods for improving the storage of distributed data and the protection of digital signatures’ integrity. The first patent proposes “a grid encoding technique for distributed data storage by using groups of collected shards, where each shard represents a logical distribution of data items stored in a given grid.” The second filing outlines a method for “signature delegation” that would protect “the integrity of digital signatures and encrypted communications.”

In this month also AWS and Kaleido, a ConsenSys’ blockchain startup, launched the “Kaleido Marketplace,” a full-stack platform that aids enterprises in implementing blockchain solutions.

In conclusion

Amazon has unveiled two new services that are blockchain-related, namely Amazon Quantum Ledger Database and Amazon Managed Blockchain. While the QLDB is designed to “provide transparent, immutable, and cryptographically verifiable log[s] of transactions that will be overseen by a central trusted authority,” the Amazon Managed Blockchain will work with the QLDB to help its users manage and adjust to a scalable blockchain network.
