How To Create Blockchain Applications

Trade Finance Transactions Simplified And Expedited

𤯠How To Build A Blockchain App In 10 Minutes

Traditionally document-intensive and reliant on bank intermediaries, Trade finance presents a particularly attractive application for blockchain. Highlighting a blockchain application use case, trade finance is relevant to companies engaging in complex transactions with high counterparty risk.

According to the World Trade Organization, an estimated $18 trillion of goods flow across international borders annually, enabled by some form of trade financecredit, insurance or a guarantee. Trade finance captures a variety of activities designed to decrease risk between trading counter-parties, particularly those that have not previously transacted.

Greasing the wheels of the trade finance machine, the letter of credit insures a seller gets paid. The buyers bank, typically working in concert with the sellers bank, issues a letter of credit. This letter ensures the seller receives payment once its goods are received, especially in the event the buyer becomes insolvent. A typical trading scenario, and its requisite document and money flows highlights the complexity of a typical trade finance transaction.

Treasury departments within global companies manage such transactions, relying on centralized, often inefficient processes. Through SWIFT alone, one of the leading global financial networks, 40 million transactions flow annually between counterparties.

So Why Start A Private Blockchain

If youre in the healthcare business, the answer is crystal clear. The concept of medical data on a public peer-to-peer network doesnt sit well with the industrys regulations. Having a private blockchain immediately removes the burden of screwing up on that, big time.

On the contrary, if you operate in finances, why limit the audience? Well, the most common reason is to remove intermediaries.

Transitioning To Blockchain Developer From A Similar Career

Upskilling is the process of teaching an employee new skills. This process is particularly useful when it comes to creating new Blockchain developers from other, similar positions in the business. Some companies, keenly aware of the growing importance of the Blockchain technology, will upskill individual employees, empowering them to handle the new tech.

If you are someone whos working at a business that pays for your upskilling costs and wants to put you in the position of Blockchain developer, remember that you will be obliged to stay with that company for at least a specific period. After all, businesses arent in the habit of paying from employees training, only to make them more marketable elsewhere!

Why Are You Integrating Blockchain

The reasons are as follows:

  • Cost benefits: For most organizations, integrating blockchain will cut operational and transaction costs by more than half although you would need to have digitized your operations because blockchain is not merely for automation.
  • Making operations transparent and transactions traceable: Blockchains transactions transparent and this helps to prevent fraud against your organization from within and outside. Because transactions are immutable and permanent it prevents people from cooking the books.
  • Automation-only adoption: If automation is the only motive then blockchain will certainly be more costly than any other automation technology, hence not very advisable.
  • Smart contracts: Further, you could consider smart contracts or dApps to automate transactions and ensure all parties adhere to agreements in the transactions.

Identify The Industry For Dapp Development

Expand the growth of your business with blockchain ...

According to State of the dApps, there are over 3,5459 active decentralized applications. Such apps are distributed through different industries, such as gaming, finance, health, security, and so on.

Lets review some of the industries that blockchain is disrupting and get some inspiration for your future project.

The technology can be used for all key services provided by banks, such as payments, clearance and settlement systems. One day, blockchain promises to put crime and fraud to rest in the financial industry. The benefits of implementing a decentralized ledger include:

  • Real-time and multi-party tracking and management of bank guarantees
  • Faster and more accurate automated reporting that draws information from immutable records
  • Faster transfer of funds between financial institutions with accelerated settlement

Numerous companies in the finance industry are already using blockchain in their daily operations. Examples include , which uses blockchain to settle US stock trades. JPMorgan Chase uses decentralized technology to facilitate transactions between institutional accounts. Ripple and R3 are among the most popular blockchains used in this industry.

Implementations: Credit Suisse, JP Morgan Chase, Western Union, Santander

In Digital Identification Process

Blockchain can be taken into practice to provide us with immutable, indisputable and secure digital identities, resulting in lesser fraud issues and seamless sign-in experience.

One of the real life use cases is the ShoCard that uses blockchain to verify an identity of individuals on their mobile devices.

Build A Private Chain

Once youve found the right development partner and refined your strategic roadmap, its time to create a private blockchain with Ethereum.

Geth Scenario

An experienced team of developers will nicely handle this task. Here are a few pointers so you can keep your finger on the pulse of what they are doing specifically:

  • configure the chains parameters in the genesis block

Simply put, thats where you can choose how fast your network will work and preallocate addresses on the chain with fake Ether balances. I call it fake because you cant transact with it on the main Ethereum blockchain. Still, within your private blockchain, its a valid cryptocurrency for transacting.

  • create accounts for users and smart contracts

Unlike run-of-the-mill software accounts, blockchain accounts dont offer much functionality beyond transacting. These accounts act like crypto wallets, allowing participants to transact on the chain, e.g., for the patient to make its medical record available for a particular clinic or doctor.

  • start mining Ether and distribute it among participants account balances according to the business model

Mining happens nearly immediately as the chain is infant, and your node does all calculations while adding new blocks.

  • add more nodes

The points above describe how developers would set up a private Ethereum blockchain using Go Ethereum , an Ethereum implementation of the Go programming language.

Types Of Blockchain Apps

As Ive mentioned above, blockchain apps still remain terra incognita, and, therefore, any idea for a distributed app holds potential. However, if we consider the types of chain apps that have gained the most traction today, well notice lots and lots of finance-related solutions.

These distributed apps go by the name of DeFi decentralized finances. DeFi solutions include a wide range of financial apps: from crypto loaning applications to decentralized exchanges to crypto wallets to payment tools, to name just a few.

You can also build blockchain apps in other popular categories such as:

  • games and gambling

To stir your imagination, lets look at some of the popular blockchain-based applications.

Applications For Blockchain In Your Business

Enums [Create Blockchain Applications Using Solidity]

      Ever since Satoshi Nakamoto published an invention he called bitcoin in 2009, cryptocurrency has had its ups and downs. More recently, however, people have looked beyond bitcoin as being a controversial currency used for nefarious black market activity and into the endless possibilities that it presents. At the forefront is the public ledger that records every bitcoin transaction known as a blockchain.

      The blockchain is now an exciting new alternative to traditional currency, centralized banking, and transaction methods that is not only changing the way we handle financial transactions, but also alternative uses that will change the world. In short, blockchain is a distributed ledger that maintains a continuously-growing list of every transaction across every network distributed over tens of thousands of computers. This makes it almost impossible to hack, changing the way banking is done.

      In my opinion, it will even change the way that you run your business from day-to-day which include the following five applications.

      When To Use Blockchain For Your Startup Or Existing Platform

      Following are some of the questions that will help you determine if integrating blockchain into your existing solution is a good idea:

      Do you want to store data?

      You dont need a database if your business solution does not require a lot of data to be stored. Therefore, blockchain is of no use in that case. If you have an application that needs to manage massive data, blockchain can be used to manage a single shared distributed ledger. Instead of maintaining multiple databases, blockchain technology will allow you to have a single transparent view of the updated ledger, shared with all network nodes.

      Is the data dynamic with an auditable history?

      Though paper-based documents are difficult to counterfeit, they have limited permanence. If transactions need to be updated and shared frequently, maintaining them on papers can be a time-consuming process. If the data and its history are crucial for your business, you might require a blockchain solution that allows multiple parties to write entries into an incorruptible system.

      Is the speed of the transaction vital for you?

      Does your database need high-performance millisecond transactions? If yes, you should stick to the centralized system for managing the records. On the other hand, even though blockchain databases are slow, they are far more secure than the centralized system. If an applications security is more important than its speed, you should look for a blockchain solution.

      Should a central authority control your data?

      Farm To Shelf: Walmart Tracing Pork Supply In China

      Food supply chains for multinational retailers present a high-stakes challenge. Every day, billions of customers expect products to be pure, clean and safe to eat. Mistakes are costly, and sometimes deadly. Contaminated products are notoriously difficult to trace, often forcing companies to respond with severe measuresincluding recalling all product or shutting down operations. In addition to risk from errors, opportunities abound for fraudulent behavior, leaving companies, and their consumers at risk.

      To picture the blockchain use case, its helpful to illustrate the food supply stages, each presenting multiple failure points:

    • Production: growing plants, raising livestock, harvesting wild species
    • Processing: converting raw materials into finished goods
    • Distribution: transporting finished goods to point of sale
    • As for all supply chains, for food there are two paramount concerns: provenance and chain of custody. Provenance refers to the origin of each ingredient. Chain of custody refers to the unbroken path a productand its upstream ingredientsfollows from the beginning of the supply chain to the customer. The chain of custody captures all the processes of converting, combing and moving product components as they culminate in the finished product at the point of sale.

      What Is Blockchain & How Does It Work

      Typical Application of the Blockchain Technology [7 ...

      As the name suggests, blockchain is a chain contains different blocks set together. Each block contains 3 pieces of information:

      • Data
      • Hash
      • Previous blocks hash

      Data Based on the use, the data that is securely stored in a block depends on the type of blockchain. For example, in the Ethereum blockchain, the data stored in the info relating to the transaction: the amount of money transferred and the data of the two people involved in the transaction.

      Remember that a blockchain is an immutable, consecutive chain of records called Blocks. They can contain transaction details, data files or any punch of data you like, really. But the important thing is that theyre chained together using hashes.

      Hash You can think of a hash as a digital fingerprint. It is used to identify a block and its data. Whats important about hashes is that its a unique alphanumeric code, usually about 64 characters. When a block is developed, so is its hash. When a block is modified, the hash is also modified. In this way, hashes are fundamental if you want to detect any changes made to the block.

      Previous blocks hash By storing the hash of the previous block, you can see how each block is linked to form a blockchain! This is what makes a blockchain so secure.

      Unfortunately, the experience of blockchain development on an industrial scale is negligible. It objectively does not allow assessing the effect. At this stage, the technology, as well as its organizational and legal support, is not yet ready for customers. So they cant start implementation on a full scale. So far, these are still pilots or prototypes that are not focused on making a profit. Although the market is ready to accept the blockchain. But this, again, in the abstract.

      Payment services, identification services, voting systems and so on are already being created with the help of blockchain. The technology is used for supply chain management, tokenization of physical assets. And there are many others.

      Like many other digital innovations, blockchain projects face challenges due to the inconsistency of current legislation with the rapidly evolving digital world. Projects in which legal difficulties do not play a leading role develop faster. An example of this is the success of supply chain management projects. The technology is used to exclude counterfeiting in the food industry. Its in the production and transportation of diamonds. In addition, blockchain is used for voting by shareholders. As the current legal regulation allows electronic voting.

      A Blockchain Is A Secure Trusted Decentralized Database And Network All In One

      Truth can only be found in one place: the code.

      In other words, a blockchain is a chain of blocks, blocks are like tables in the database but they cannot be deleted or updated, blocks contain information . the blocks are cryptographically verified and chained up to form an immutable chain of blocks called a blockchain or a ledger.

      The same chain is then distributed to all the nodes across the network via a P2P network.

      So, instead of a centralized database, all the transactions that are shared across the nodes are contained in blocks, which are chained together to create the ledger. This ledger represents all the data in the blockchain. All the data in the ledger is secured by cryptographic hashing and digital signature and validated by a consensus algorithm. Nodes on the network participate to ensure that all copies of the data distributed across the network are the same.

      5 key concepts to remember in the blockchain ecosystem:

    • Cryptographic hash and digital signature
    • Immutable ledger
    • Consensus algorithm
    • Block validation
    • I will explain these concepts more in detail as we go.

      Benefits of using blockchain:

      blockchain is not a silver bullet, so use it when :

    • The data stored cannot be modified
    • The data cannot be denied by its owner
    • You want decentralization
    • You want one source of truth
    • You want high security
    • You dont care about speed . But some blockchains are faster because they use different consensus algorithms other than PoW. We will talk about this later.
