AWS and Blockchain

What is the technology behind blockchains?

Transparent information sharing inside a firm network is made feasible by an advanced database system known as blockchain technology. In a blockchain database, data is kept in blocks within a blockchain database, which are connected by links. Because the chain cannot be removed or altered without network approval, the data is consistent across time. Thus, you may utilize blockchain technology to create an irreversible or immutable ledger that will allow you to track payments, purchases, accounts for users, and other transactions. System built-in features prohibit unauthorized transaction entries and guarantee consistency in the shared view of these transactions.

Why does Blockchain Matter?

There are various obstacles when it comes to capturing financial transactions with traditional database technologies. Take a sale of a property, for example. The ownership of the asset passes to the buyer once payment exchanged. Both the seller and the buyer can independently record the financial operations, but neither source is reliable. Both the buyer and the seller might easily claim that they might are paying the money regardless of whether they haven't received it, or that they haven't received it as all.

Transactions must be supervised and validated by a reliable third party to prevent possible legal problems. In addition to making the transaction more difficult, the existence of this centralized authority adds one more point of risk. If there was a breach in the central database, both parties are suffered.

Blockchain reduces these problems by establishing a decentralized, impenetrable transaction record system. Within the real estate transaction context, blockchain generates a single ledger for both the vendor and the buyer. Every transaction is automatically updated in real time in both parties' ledgers and requires approval from both parties. The complete ledger will become tainted if there is any corruption in past transactions.

How is blockchain applied across different industries?

Blockchain is a new technology that many different sectors are embracing creatively. We go over a few use scenarios across several industries in the subsections that follow:

1. Energy Businesses:

Businesses in the energy sector that employ blockchain technology have created a market place where individuals may exchange electricity. Using this platform, solar-panelling homeowners can sell their extra solar energy to nearby residents. The majority of the procedure is automated: blockchain records the transactions that smart meters produce.

Users in communities without access to energy might sponsor and own solar power plants through crowd fundraising projects based on blockchain technology. After solar energy systems are built, sponsors may also get rent for these neighbourhoods.

2. Money:

Blockchain services are used by established financial institutions, including as banks and exchanges for stocks, to handle payments via the internet, user accounts, and trading on the markets. For instance, blockchain technology is being used by Singapore Exchange Limited, a holding company for investments that offers financial trading services across Asia, to create an interbank payment account that is more effective. They overcame a number of obstacles by implementing blockchain, such as batch processing and the laborious manual reconciliation of thousands of financial transactions.

3. Entertainment and media:

 Blockchain technologies are used by media and entertainment companies to handle copyright data. Verifying copyright is essential to paying artists fairly. To document the purchase or transfer of copyrighted content, many transactions are required. Blockchain services are used by Sony Music Entertainment Japan to improve the effectiveness of digital rights management. They have effectively reduced expenses and increased productivity in copyright processing by utilizing the blockchain technique.

Characteristics:

1. Unchangeability:

Something is said to be immutable if it cannot be modified. Once a transaction has been entered into the shared ledger, nobody else can alter it. In the event that a transaction record has an error, the error must be corrected by adding a new transaction, and the network can see both transactions.

2. Agreement:

Rules about consent from participants are established by a blockchain system in order to record transactions. Only when the approval of the majority of network participants is obtained can new transactions be recorded.

AWS Blockchain:

Whether you require a multi-party, entirely managed blockchain-based system that helps eliminate middlemen or a centrally managed database that keeps an unchangeable and cryptographically verified record of transactions, AWS offers tools designed specifically to meet your unique needs.

Compared to other cloud vendors, AWS has the highest level of client trust for blockchain technology and ledger technology workloads.

All of the major blockchain protocols, including as Hyperledger Sawtooth Networks, The Corda network, DAML, the Ethereum platform, the quorum, Blockstack, Blockapps a lot more, are supported by more than 70 verified blockchain solutions offered by partners on AWS.

With AWS, creating blockchain and ledger apps is easier, quicker, and more effective. By cutting the time it takes to host Hyperledger Fabric frameworks by 60%, Amazon Managed Blockchain does away with the labour-intensive work needed in setting up blockchain networks. Because managed blockchain supports AWS CloudFormation, AWS CLI, and Amazon CloudWatch logs, it greatly simplifies network operations. In addition to being two to three times faster than conventional frameworks, Amazon QLDB offers transaction handling capabilities such as document data models and SQL-like operators.

AWS Blockchain Services:

AWS Blockchain services offer specially designed tools to meet your needs. They can be used to create anything from a multi-party, a fully managed blockchain system that eliminates the need for middlemen and connects to a central database that maintains an ongoing record of transactions. With partners that support all main blockchain protocols, such as Hyperledger, Corda, Ethereum, Quorum, and more, AWS offers a plethora of verified blockchain solutions. Because of this, using AWS to construct blockchain and ledger apps is simpler, faster, and more effective.

The following are some helpful AWS Blockchain services:

• QLAB is transparent, unchangeable, and using cryptography verifiable transaction log is provided by the fully managed ledger database Amazon Quantum Ledger Database (QLDB). Every data modification is accurately and sequentially entered into an integrated logbook. Because a journal is append-only, users can add data, but they cannot remove or overwrite it.
• With Hyperledger Fabric and Ethereum, Amazon Managed Blockchain is a completely managed solution that simplifies the creation and management of scalable private networks or the joining of public networks. Open an AWS account to get started with blockchain.

centralized ownership:

The ledger can be shared among any number of people involved in collaboration and is owned and managed by a central, trustworthy authority. Provides a consolidated, unchangeable, and securely verifiable transaction log. Fully controlled ledger database

Distributed ownership:

It is not necessary for parties to understand or trust one another in order for transactions to take place. Each peer node in a network is owned by each party, referred to as a member. A fully managed solution that simplifies the development and administration of distributed ledger technologies and scalable blockchain networks

How it functions?

A fully managed solution called the Amazon Managed Blockchain (AMB) may assist you in creating robust Web3 apps for public and private blockchains. For immediate, serverless access to several blockchains, use AMB Access. Without worrying about setting up specific blockchain infrastructure or maintaining connectivity to the blockchain network, you can focus on developing Web3-ready applications. Using developer-friendly APIs, AMB Query lets you retrieve historical and real-time data from several blockchains. Without the requirement for specialist blockchain systems or ETL (extract, convert, and load) processes, standardized blockchain data may be connected with AWS services. For both conventional consumer application builds and institutional grade builds, all AMB functionalities scale securely.

Currently, Ethereum, Polygon, Bitcoin, and the Hyperledger Fabric blockchains are supported by Amazon Managed Blockchain. Visit the AMB Access and AMB Query to find out more about each.

How Blockchain Can Help You with AWS?

Track and identify

Track-and-trace implies the capacity to determine all product inventory's historical locations as well as its current locations, along with the past of product custody. Today's supply chains frequently struggle with track and trace because of antiquated paper procedures and fragmented data platforms that impede communication. Supply chains are vulnerable to issues including manual errors, counterfeiting, inaccuracies in supply and demand forecasts, visibility gaps, and compliance violations when there is a lack of data compatibility.

Whole supply chain networks may record modifications to an individual shared ledger with Amazon's Managed Blockchain, giving them complete data accessibility and one single point of truth. Businesses can always check the status and location of a product because transactions are time-stamped and updated. This aids in the fight against problems like waste, delays, and counterfeit items in compliance violations. To confirm the legitimacy of their products and the morality of their supply chains, businesses can also provide track and trace information to their clients.
