8 Industries Embrace Blockchain Innovation Sumeet Shah February 9, 2023

What is blockchain?

  • A blockchain is a distributed database that manages and stores data. Blockchain technology does not have a centralized control or database. It stores information in blocks that hold data and are linked to previously filled blocks, creating a data blockchain.
  • There are mainly two types of blockchain systems – open & closed. Open blockchains allow the general public or huge audiences to access all the ledger data. And is also known as the ‘public’ blockchain. Closed blockchains are designed to restrict who can see the information stored within them. It is also known as a ‘private’ blockchain.
  • When people use a blockchain-based app like cryptocurrency, they all work with the same database stored on many computers called “nodes”. Specific blockchain procedures are used to confirm these transactions to ensure everything is accurate and secure. 
  • Bitcoin is the best example of a decentralized digital currency that records and verifies transactions using blockchain technology. Did you know that the first Bitcoin transaction in real life cost 10,000 Bitcoin in exchange for two pizzas?
  • 90% of US and European banks and financial institutions have started exploring blockchain technology. Walmart, Pfizer, AIG, Siemens, Unilever, and a plethora of other companies have already adopted blockchain.
  • So far, over 400 applications have been developed on the blockchain platform, including identity management, SCM, and gaming. The community also offers several tools for customizing blockchain implementations for various decentralized use cases in SCM, healthcare, and DeFi.

8 most popular blockchain applications of 2023

1. Gaming

The video game industry is quickly adopting blockchain technology, specifically through non-fungible tokens (NFTs). In-game economies and unique items are frequently used in games, and NFTs provide a way to facilitate that economy while also ensuring that players’ items are accessible across games. GameFi is the best example of blockchain integration within the gaming industry. GameFi is a combination of gaming and decentralized finance (DeFi) that describes integrating blockchain applications in the gaming sector, other than, say, for monetization purposes. Small-scale publishers, in particular, take advantage of the ability to monetize their games by issuing such non-fungible tokens.

2. Manufacturing

Blockchain technology has several potential applications in the manufacturing industry, from supply chain management to quality control and compliance. One practical example of how blockchain is used in manufacturing is tracking product and component authenticity. By capturing each step of a product’s journey through the supply chain (on a blockchain), manufacturers can ensure that the products they receive are genuine and not counterfeit. They can better track the movement of goods and optimize their operations by creating a decentralized, secure ledger of supply chain data. Also, the combined power of blockchain and IoT can transform how businesses manage their products in this industry. With these two game-changing technologies, companies can unlock many benefits, including enhanced product safety, streamlined tracking capabilities, and more efficient warranty management. Industry analysts estimate that nearly 30% of manufacturers (with a revenue of over $5 billion) will incorporate blockchain into their industry 4.0 projects by 2023. 

3. Supply chains

Using blockchain technology to track items moving through a logistics or supply chain network can benefit greatly. For starters, it facilitates partner communication because data is available on a secure public ledger. Second, because the data on the blockchain cannot be altered, it provides greater security and data integrity. As a result, logistics and supply chain partners can collaborate more easily, with greater confidence that the data is accurate and up-to-date. IBM Blockchain is used in the supply chain industry to improve supply chain operations’ transparency, traceability, quality control, provenance, payment processing and efficiency.

4. Finance

The world of finance has always been driven by innovation, from the invention of paper money to the advent of credit cards. However, despite all these advances, the system still has many inefficiencies, particularly regarding settlement and clearing times. In the stock trading industry, for example, it can take up to 3 days (or longer if trading internationally) for the settlement and clearing process to complete, which means that the money and shares are essentially frozen. This can incur high costs and risks for banks, given the magnitude of the sums involved. This is where decentralized finance (DeFi) comes in. Using secure distributed ledgers similar to the ones used by cryptocurrencies, DeFi represents a new and exciting way of conducting financial transactions. With DeFi, settlement and clearing times are reduced to near-instant speeds, meaning that money and shares can be transferred in a matter of seconds.

5. Healthcare 

Blockchain’s smart contracts have significant potential to impact the healthcare industry. The blockchain platform codes these contracts to execute automatically when certain conditions are met, allowing parties to create contracts without intermediaries. They can also encode wearable health records to ensure privacy and security, as only authorized providers with a key can access them. In this way, smart contracts can aid in enforcing the HIPAA Privacy Rule, which is crucial for protecting patient information. Blockchain’s smart contracts represent a new era of innovation for the healthcare industry with the potential to streamline processes and improve patient outcomes.

6. Advertising

The digital advertising industry is currently plagued by issues such as ad fraud, lack of transparency, and a complex supply chain involving multiple intermediaries. Blockchain technology allows advertisers to create a decentralized, transparent, and tamper-proof platform for buying and selling digital ads. For example, the blockchain-based advertising platform, AdEx, uses a smart contract system to automate the buying and selling of ad space. Advertisers can create digital ads stored on the blockchain and set up automated bidding rules that are executed in real-time. Publishers can then monetize their ad space by selling it to advertisers directly, cutting out intermediaries and reducing costs. Eventually, it can also increase trust and confidence in the advertising industry, as advertisers can be confident that their ads are being displayed to real people securely and transparently.

7. Insurance

Traditionally, insurance policies and claims are stored on centralized databases vulnerable to data breaches and hacking. But with blockchain, insurers can create a secure and decentralized record of insurance policies and claims resistant to tampering and fraud. Blockchain can easily streamline the claims processing system, which we all know can be a real headache. The process is usually time-consuming and involves multiple parties. But with blockchain, the shared and transparent ledger allows all parties to access real-time information, speeding up the process and reducing errors. Enterprises can also leverage blockchain for risk management to analyze data from various sources and create predictive models that help in risk management. Insurance companies might anticipate a breakthrough from Ethereum’s smart contracts and decentralized apps in the forthcoming years.

8. Cyber Security

Blockchain has the potential to enhance cyber security in many ways, including the secure storage and transmission of data, verification of identities, and protection against fraudulent activity. It can generate a decentralized identity management system that eliminates the need for a central authority to verify identities. This ensures that users have control over their data and can securely share it with only those they trust. Utilizing a distributed ledger can render it extremely difficult for a hacker to manipulate any information kept on the blockchain. One of the best examples is DNS. The Domain Name System (DNS) is a public directory that connects domain names to their IP addresses. Over time, hackers have attempted to gain access to the DNS and exploit these links, resulting in site crashes. But with blockchain’s immutability and decentralized systems, the DNS can be securely stored.

Conclusion

Despite being a relatively new technology, blockchain has already shown great potential in revolutionizing businesses’ operations. In the last 15 years, companies have experimented with blockchain in various ways, yet the possibilities for its application are still being explored. As the world increasingly relies on digital technology, there is a growing demand for secure, transparent, and tamper-proof data storage and sharing. Blockchain technology has emerged as a promising solution to meet these needs. Its ability to ensure data integrity, establish trust, and facilitate decentralized transactions can transform industries ranging from finance and cyber security to supply chain management and more.

Why is Blockchain the future of Technology? Harshal Sonavane December 12, 2022

What is Blockchain?

Blockchain is a system in which a record of transactions, especially those made in a cryptocurrency, is maintained across computers that are linked in a peer-to-peer network.. Its power and inventive traits stem from the presence of several unique properties and novel methods. Blockchain is a sort of database, but it varies significantly from traditional databases in how it stores and handles information. Blockchain holds data in blocks that are digitally connected together rather than rows, columns, tables, and files like traditional databases do. Furthermore, a blockchain is a decentralized database administered by computers in a peer-to-peer network rather than a central computer as in traditional databases. 

 

Why is Blockchain Important?

Blockchain enables multi-step transactions that require verification and traceability to be verified and traced. It can help to ensure secure transactions, reduce compliance costs, and speed up data transfer processing. Blockchain technology has the potential to improve contract administration and product auditing.

The global blockchain industry increasing to $20+ billion in 2023 is another indication of how quickly businesses are adopting blockchain.

So, what exactly makes blockchain so appealing to businesses? First and foremost, it lowers operational expenses. The elimination of middlemen is beneficial to the company since it decreases not just costs but also the point of contact, enhancing efficiency and development.

 

Pros and Cons of Blockchain

No.

Pros

Cons

1

Faster transactions and 24/7 access

Data is not totally immune to cyber-attacks.

2

Because it is a distributed ledger, it produces numerous database copies throughout the network, so it is extremely safe.

High electricity use may be harmful to the environment.

3

There are no third parties or middlemen.

If you lose your private key, you cannot retrieve your account since there is no central intermediary.

4

Records or information maintained using blockchain technology are permanent, therefore there is no need to worry about losing the data.

Blockchains need miners or those with powerful computers and specialized software that solve computational challenges in return for fresh crypto coins.

 

Types of Blockchain

Public Blockchain

A public blockchain is a permissionless, non-restrictive distributed ledger technology. Anyone with an internet connection may sign up for a blockchain platform to become an authorized node and join the blockchain network. A node or user on the public blockchain is permitted to view current and historical information, validate transactions, or perform proof-of-work for an incoming block, and mine. The most fundamental application of public blockchains is cryptocurrency mining and exchange. As a result, Bitcoin and Litecoin blockchains are the most commonly used public blockchains. If users closely adhere to security rules and practices, public blockchains are largely safe. However, it is only dangerous when players do not strictly adhere to security standards.

Private Blockchain

A private blockchain is a limited or permissioned blockchain that operates solely within a closed network. Private blockchains are often utilized within an organization or company where only selected members of a blockchain network participate. The governing organization determines the degree of security, authorizations, permissions, and accessibility. Thus, private blockchains function similarly to public blockchains but have a smaller and more restricted network. Voting, supply chain management, digital identification, asset ownership, and more applications use private blockchain networks.

Example – Hyperledger Fabric, Enterprise Ethereum

Consortium Blockchains

Consortium blockchains are permissioned blockchains that are administered by a collection of organizations rather than a single corporation, as with private blockchains. As a result, consortium blockchains have greater decentralization than private blockchains, resulting in higher levels of security. However, forming consortiums may be a difficult process since it necessitates collaboration across several firms, which creates logistical obstacles as well as possible antitrust risk (which we will examine in an upcoming article). Furthermore, some supply chain participants may lack the necessary technology or infrastructure to use blockchain technologies and those who can decide that the upfront expenses are too high to pay to digitize their data and link to other supply chain members.

Example – R3

Hybrid Blockchain

A hybrid blockchain is one that combines private and public blockchains. It combines the properties of both types of blockchains, allowing for both a private permission-based system and a public permission-less one. With such a hybrid network, users can control who gets access to which data is stored in the blockchain. Only a selected section of data or records from the blockchain can be allowed to go public, keeping the rest confidential in the private network. The hybrid system of blockchain is flexible so that users can easily join a private blockchain with multiple public blockchains. A transaction in a private network of a hybrid blockchain is usually verified within that network.

Example – Food Trust by IBM

 

Winding Up

There should be no doubt that blockchain technology will benefit and attract a wide range of potential enterprises and organizations, all of which will undoubtedly invest in it. While it will serve as a remedy for various market obstacles, the technology still has a long way to go.

There will be a significant development in this field over time; whether you are a tech enthusiast or not, blockchain technology offers new and interesting work and investment prospects to offer, all of which are worth examining.
