Blockchain for Beginners: Unlock 8 Revolutionary Uses Beyond Cryptocurrency
Introduction
Most people associate cryptocoin when blockchain has been mentioned for the first time. However, the blockchain is not limited to serving as the backbone to our digital currencies. This new technology has been revolutionizing a wide range of industries that are decentralized, transparent and secure. This beginner friendly guide explores blockchain fundamentals and explore 8 groundbreaking applications of blockchain technology that aren’t cryptocurrency.
Firstly Understand Blockchain?
Also referred to as ‘nodes,’ a network of like minded individuals is used to record and validate transactions on an electronic ledger called a blockchain. Created originally for Bitcoin, the first cryptocurrency, it has been incorporated in a variety of industries due to its security, transparency and decentralization characteristic applications.
Blockchain in Detail
Transaction Initiation: When a person wants to add data (or information) to the blockchain, a transaction is made. It could be any data- financial transactions, a record of goods moving through a supply chain, personal medical information and so on.
Block Creation: Other recent transactions are bundled into a block and are considered the transaction. A block is then think of as a page in a ledger that contain a list of the transaction on that block.
Each block includes Data: The exact breakdown of tokens for a blockchain may depend on what you’re trying to accomplish with that blockchain (e.g. bitcoin transactions or product details in a supply chain). Timestamp: The exact time of when the block was created. Previous Block’s Hash: Code unique to new block referring to previous for linking continuity of chain.
New Hash: A mathematical identifier used to identify this block unique. The block has to be sure this hash ensures the integrity of this block.
Verification and Consensus: Before we add the block to the chain, we have to verify the block by the network. To make that possible, we have a process called consensus where lots of different nodes (or computers in the network) have to ensure that the transaction was accurate and valid.
Types of consensus mechanisms are:
Proof of Work (PoW): When a new transaction is verified, the Miner does have to validate it by solving a complex equation.
Proof of Stake (PoS): Validators are chosen based on the coins that they have, how much they are willing to stake as collateral. PoW is much more energy consuming than PoS.
Adding the Block to the Chain: It is once verified that the block is added to the end of the chain making it a permanent part of your blockchain. The process itself isn’t centralized: there’s no central authority that determines how new blocks are added.
Key Features of Blockchain
Decentralization: Centralized system is a traditional where a single entity (let say a bank) controls and validates transaction. As opposed, blockchain is decentralized, the control does exist in a network of nodes. This eliminates the need for the intermediaries, giving you the faster transactions and lower cost.
Secondly, blockchain is also decentralized, and as such is more resilient to attacks—they are resistant to any single point of failure.
Transparency: Blockchain ledgers are public and open. Transactions are pseudonymous, so though you can see transaction details, you won’t always know the various parties involved. All of them can see all transactions made on the network, though. This transparency fosters trust, and verifies data in real time.
Security and Immutability: Indeed, blockchain’s security depends on its cryptographic structure. Cryptographic algorithms are used to each transaction. For each block, the data inside it is hashed to create the unique hash, and if you attempt to play with this data it will modify the hash which then becomes very obvious that the data inside has been changed.
Distributed Ledger Technology (DLT): Each node has a blockchain with complete network. The added security is by giving this one additional distribution, so if one node is compromised the whole network is still intact. Each node has a complete network of blockchain. This additional distribution increases security because if one node is compromised the entire network is still safe.
Consensus Mechanisms: A blockchain is a chain of transactions and the way you write the blockchain is fully defined by its consensus mechanism. For example without relying on a centralised authority this ensures that no one has spent money twice neither through fraud nor double spending.
Benefits of Blockchain’s Structure:
- Elimination of Intermediaries: Transactions between parties are possible directly, without using intermediaries and reducing the cost of transaction.
- Enhanced Security: Since the blockchain is cryptographically safe; data is protected, and it is hard to hack or edit it.
- Traceability: A blockchain is to be used when creating an audit trail, in an environment where you require accountability of actions.
- Faster Transactions: Transactions on blockchain are very often faster, even anonymous, and without intermediaries.
Real-World Example of Blockchain Structure in Action:
Take for example a product in a supply chain that is followed from its start to its end. With a block, everything from raw material extraction to distribution, to retail can be recorded in order, from step to step. During each verification of the product’s transaction and addition to the chain, stakeholders of the supply chain can see real time data about the location, condition and status of the product. The resulting transparency is a powerful fraud, counterfeiting and inefficiency protection.
How Blockchain Works (With Example):
- Transaction Creation: Whether it is a data record our financial transfer or tracking a product, the transaction is initiated.
- Block Formation: Blocks are collected together to create the “transaction”. The block here contains a code (or hash) which is unique and a pointer to the previous block.
- Verification: The network verifies the block using a means of consensus proof of work and proof of stake, respectively.
- Addition to Chain: Eventually, this block is verified, and the data is added to the chain, and subsequently linked to the block before it. We know blockchain for the cryptocurrency, but it has a transparent, secure nature that can be adapted into many different fields. 8 revolutionary applications above cryptocurrency.
8 Revolutionary Uses of Blockchain Beyond Cryptocurrency
1. Supply Chain Management: Blockchain makes it easier for companies to monitor a product’s origin from source to consumer. The supply chain can be recorded in the same on the blockchain, which will guarantee the authenticity and transparency as the stages of supply chain. Most importantly, this is useful in industries where being able to trace where goods originate (e.g. food or pharmaceutical) is important.
2. Healthcare Patient: data now has a secure home in a blockchain. With healthcare provider access to reliable, up to date information on a blockchain, patients’ information remain private while their care improves with diagnosis and treatment.
3. Finance Blockchain: doesn’t stop at cryptocurrency. It’s taking over traditional finance. Blockchain is being used by banks to reduce the cost and speed up cross-border payments, without having to engage with digital currency.
4. Voting Systems: Scalable, transparent, and tamper resistant blockchains can provide an answer to this problem of ours. We can record the votes on a blockchain, so that each vote will be properly counted, avoiding manipulation of the votes.
5. Intellectual Property: Blockchain can be used by artists, musicians, and creators, to protect their intellectual property. With blockchain, they can record proof of ownership (and secure ownership rights) against the possibility of their work being used improperly.
6. Real Estate: For real estate, blockchain removes a lot of the hassle of purchasing and selling by securely recording property transactions. A blockchain can store ownership records which can make processes faster and reduce the risk of Fraud.
7. Education: It’s making it safer to store educational credentials on the blockchain, so that employers and institutions can verify them more easily. This technology decreases fraud of credentials and increases trust in the processes of academic achievements.
8. Logistics and Transportation Logistics: is, today, being transformed with blockchain which offers real time tracking of shipments. Transparency in goods inventory management is enhanced by this and fraud is prevented, so operational costs are reduced and you can be sure goods arrive on time.
