Aws qldb vs blockchain
They've created a way to connect small farms in developing nations to banks and distributers of goods, like seeds, fertilizer, and tools. Traditionally, rural farms have been ignored by the financial world, because they don't normally have the information required to open an account or apply for credit. With HARA, this hard-to-obtain data on small farms is collected and authenticated, giving these farmers access to resources they've never had before. A major component to the system that HARA created is blockchain.

How enterprises use Hyperledger Fabric on Amazon Managed Blockchain #reinvent [OPN217]
Here's how the new services can potentially impact your organization. Amazon Web Services AWS has been famously resistant to blockchain adoption, despite the distributed ledger technology now being nearly a decade old.
At AWS re:Invent , the company announced two blockchain services, allowing users to create a private blockchain or blockchain implementation for potential business use cases. The second, Amazon Managed Blockchain, allows users to create and manage blockchain networks using the Ethereum or HyperLedger models. Blockchain is a computing model which enables the decentralized management of records in a permanent and verifiable way.
By design, it is intended to be tamper-proof—each block contains a cryptographic hash of the previous block—making retroactive editing of transactions in the blockchain impossible without altering all of the blocks that followed it. For decentralized blockchains, this is a practical impossibility due to the distributed control of the network. The technology was developed by the pseudonymous programmer Satoshi Nakamoto as the underpinning of the Bitcoin cryptocurrency.
Since then, other cryptocurrencies have been built on top of the concept, while some groups have explored applying blockchain to other use cases. These include managing transaction records for traditional currencies, as well as more inventive uses like land registration, smart contracts, and federated social networking. Strictly speaking, there is not a universally accepted definition of blockchain.
The cryptographic hashing features which make the technology suited to digital currency applications like Bitcoin—when applied to use cases with a central trusted authority—make the technology little more than a computationally intensive database.
The value of QLDB is ease of deployment. Relative to the amount of work and compute nodes required to deploy Hyperledger Fabric or Ethereum, QLDB simplifies the deployment of a ledger database. To contrast, Amazon Managed Blockchain is a full blockchain network which automatically scales the resources needed to operate networks using Hyperledger Fabric or Ethereum frameworks.
Strictly speaking, it has always been possible to implement blockchain on AWS, via a standard EC2 compute instance. QLDB occupies an uncomfortable middle ground, in terms of technology.
The centralized nature of the service gives it all of the immutable properties that blockchain has, though these immutable properties mean it has limited practical business application to justify the computational overhead and expense that accompanies a blockchain deployment.
If, somehow, you have a business use case which requires an immutable database because the product design potentially allows users to modify data or attributes of other users, you have a design problem. Throwing blockchain at this would not be helpful or cost effective. Likewise, if you have a design which can result in unintended changes to data, you have a data recovery or version control issue.
These are problems which can be fixed easily with less engineering talent than is required to adapt these use cases to QLDB, with a lower operating cost. If, for some reason, you have a business case that actually requires distributed control and reporting—as a simple example, imagine a federated rewards system which allows customers to earn points across stores with different owners, with redemption cost offset calculated proportionally by the stores at which the points were earned—deploying blockchain would be useful.
The number of these use cases is not abundantly high, but is nonzero. With those disclaimers in mind, if you are absolutely convinced of a business need to use blockchain, the AWS implementation of ledger or blockchain applications is quite likely to be the easiest path to implementing that for your business, with that ease of use magnified if you are already using other AWS products in your organization.

Amazon Unveils ‘Immutable’ Quantum Ledger Database Product
With the increasing popularity of enterprise blockchain companies, a considerable number of technical experts believe that this kind of decentralization is not always necessary. It was originally announced at AWS: invest , targeting organizations that want to have transparent, unchangeable and encrypted verifiable transactions on Amazon Web services AWS , but do not need decentralization and blockchain. In many cases of financial services, such as issuing and managing central bank digital currency CBDC or Australian Stock Exchange ASX replacing chess settlement and settlement system, there is no need for public ledger, and only one management agency controls data and process, and there is no need to include consensus driven blockchain. Now they use cash as a decentralized asset that cannot be easily tracked, thus driving the development of centralized digital assets. Things can get complicated when designing such systems and requirements go beyond the scope of the central bank.

What is BigchainDB? A database with blockchain characteristics. With high throughput, low latency, powerful query functionality, decentralized control, immutable data storage and built-in asset support. A fully managed ledger database. It can be used to track each and every application data change and maintains a complete and verifiable history of changes over time.
Amazon Quantum Ledger Database now generally available
Amazon Quantum Ledger Database QLDB is a purpose-built ledger database that provides a complete and cryptographically verifiable history of all changes made to your application data. Traditional databases allow you to overwrite or delete data, so developers use techniques such as audit tables and audit trails to help track data lineage. While these approaches can work, they require custom development, can be difficult to scale, and put the onus on the application developer to ensure all the right data is being recorded.

Customers who want to allow multiple parties to execute transactions and maintain a cryptographically verifiable record of them without the need for a trusted, central authority can quickly setup a blockchain network spanning multiple AWS accounts with a few clicks in the AWS Management Console. Amazon Managed Blockchain scales to support thousands of applications and millions of transactions using popular open source frameworks like Hyperledger Fabric and Ethereum. The AWS BaaS is for private or permissioned blockchains using a distributed ledger, in this case the Hyperledger Fabric from the Linux Foundation, where the parties are known to each other and operate in a private or closed network. By providing the management of the underlying blockchain, AWS has opened the door for any AWS customer to experiment, test a proof-of-concept, or roll out a production blockchain within its known business or partner networks without having to worry about the overhead of managing the underlying blockchain fabric. They get the benefits of blockchain without the underlying technical talent requirement.
