Blockchain Demystified: Exploring its Potential Beyond Cryptocurrency
Blockchain technology is closely associated with cryptocurrencies like Bitcoin and others. The potential of blockchain technology extends far beyond just the financial sector. Cryptocurrencies have demonstrated leveraging the power of blockchain for decentralizing finance.
The underlying technology offers a wide range of use cases across industries involving supply chain management, healthcare, voting system, intellectual property protection and much more. It is quite crucial to understand the working of blockchain and its broader application so that it can help to mystify the transformative technology and highlight its far reaching potential.
In this blog, we will discuss the concept of blockchain, the way it’s work and how it can be applied in different industries beyond cryptocurrency.
Understanding blockchain
Blockchain is a decentralized and distributed digital ledger which records transition across multiple computers. It ensures transparency, immutability and security. It differs from the traditional centralized databases in the way that it relies on nodes which is a network of participants to collectively manage the data.
In each block of blockchain, a list of transactions is contained in which a block once done is linked to the previous block in a chronological manner hence forming the blockchain. These linked blocks are permanent and forms immutable record and all transactions which occurs on the network.
Key advantages of blockchain structure
- Since the ledger is decentralized, all the participants in the network can access the same version of the data fostering transparency, trust and accountability among users.
- Blockchain uses cryptographic techniques to secure its data which makes it highly resistant to temper or hack information. Once a block is linked to the other block, it becomes quite impossible to be modified without the consensus of the network participants.
- Once the transaction is recorded on the block, it cannot be altered or deleted due to its cryptographic nature and consensus mechanism. You can ensure to preserve the historical data and it’s not easy to be tempered with.
- Since there is no any central authority, hence blockchain is highly resistant to censorship and control by a single entity. It also reduces the risk of manipulation.
Understanding the working of blockchain technology
The transaction is initiated by a participant. The participant can be a user, company or device on the blockchain network. You might be asked to transfer your data and information to the other participant as well. The transaction is then broadcast to the network where it is verified by multiple nodes to ensure that the transaction is legitimate. The verification process varies upon the consensus mechanism used.
Once your transaction is verified then it is grouped into other transaction to form a block. These blocks are then added to the chain when it is validated by the network. The network then reaches to the consensus where it agrees that the transaction and the new block are legitimate.
It can be done using a consensus protocol to ensure that all participants in the network agree on the validity of the transaction. Once the consensus is reached then the block is added to the existing blockchain and the transaction is recorded in a manner such that it cannot be altered and reversed further. The updated blockchain is now available to all the participants in the network.
Blockchain beyond cryptocurrency
One of the most well known applications of blockchain is cryptocurrency. But the blockchain technology has proven to be useful in a variety of sectors. Some of the most promising and impactful application of this technology beyond cryptocurrency are listed below-
- Supply chain management: It is a complex system with different stakeholders with their own records and processes. Block chains can bring transparency and accountability in the supply chains by reducing fraud and improving the efficiency. Blockchain allows tracking of the products from their source to their end customer. It can also prevent counterfeit products from entering into the market. By reducing manual tracking and administration, blockchain can streamline the supply chain processes by being time effective.
- Healthcare: The healthcare industry deals with sensitive data include the record of patient, treatment histories and result. Blockchain technology can revolutionize the healthcare sector by providing a secure and transparent record of patient data by improving data share and ensuring the privacy. Block chain technology can also be used to track their production, distribution and consumption of pharmaceuticals by ensuring that drugs are authentic and safe.
- Voting systems: Blockchain technology can revolutionize the entire voting process by providing a transparent and secure system. It can provide a decentralized Ledger record where each vote will be treated as a unique transaction. The use of blockchain technology and voting eliminates manipulation and fraud.
Future of block chain technology
- It can be used in verify academic credentials. It can provide a tamper proof record of degrees and certificates to streamline the hiring process.
- It can also be used to create decentralized energy grids where people can buy sell and trade energy directly with each other.
- It can also be used for tax collection, land registry and identity management.
Conclusion
Block chain is not just limited to cryptocurrencies. It can revolutionize various industries by improving its efficiency and increasing transparency. With the advancement in technology, it will continue to evolve at unlock new opportunities.
