Amazon Presents Its Quasi-Blockchain Solution, Platform for Ethereum and Hyperledger Fabric

▤ Summary

" Indeed, Andy Jassy, the CEO of Amazon Web Services (AWS), reportedly stated that the QLDB “will be really scalable, you’ll have a much more flexible and robust set of APIs [application program interfaces] for you to make any kind of changes or adjustments to the ledger database.”Additionally, QLDB allegedly uses a cryptographic hash function (SHA-256) to generate a secure output file of data’s change history, serving as a proof that “validates the integrity of data changes.”“Permissioned blockchains handle cryptography in a decentralized way, which provides properties like historical evidence [...] Another relevant point is the value of the smart contracts or chaincodes, which function as agreed and signed rules on how to modify the data.Further, the product automatically scales depending on the needs of specific applications and is deployed in managing certificates, inviting new users to the network and tracing metrics, such as memory and storage resources and usage of computer, Amazon argues.Montes, in turn, doesn’t believe that a managed blockchain service offering may be around for long because “it limits open scalability (in a technology that is based on network-effects) by locking it up into a single cloud provider.” However, such solutions might be useful for testing and proof-of-concept ( PoC ) operations, he adds.
