Blockchain technology’s potential use cases go far beyond digital currencies. It’s unique architecture opens up numerous opportunities across many industries. This article will explore blockchain use cases in the real-world and examples of companies leveraging blockchain to revolutionize various sectors.
What is Blockchain Technology?
Blockchain technology is an advanced database mechanism that allows transparent information sharing within a business network. A blockchain database stores data in blocks linked together in a chain. The data is arranged in chronological order because you cannot delete or modify the chain without approval from the network.
Blockchain creates a decentralized, tamper-proof system to record transactions. Using real estate transactions as an example, blockchain generates a single ledger for the vendor and the buyer. Every transaction is automatically updated in real-time in both parties’ ledgers and requires approval from both parties.
Key Features of Blockchain Technology
Since blockchain isn’t just a backup for cryptocurrencies, let’s explore some of the key features of Blockchain technology.
- Decentralization
- Immutable
- Transparent
- Secure
- No third parties
- Consensus
Decentralization
Decentralization in blockchain refers to transferring control and decision-making from a centralized entity (individual, organization, or group) to a distributed network.
In blockchain technology, transactions are verified, records are maintained across many nodes, and there is no single point of failure or control. Control means that no single entity can have control over an entire network.
Immutable
Immutability means something that can’t be changed or altered. Once data is recorded on a blockchain, it is extremely difficult to modify or remove. This is because the blockchain relies on a collection of nodes.
Validation is needed from the majority of the nodes before records on the blockchain can be altered (or deleted or added). This is called consensus. Records are permanent, chronologically ordered, and securely linked, providing an irreversible audit trail and preventing tampering.
Transparent
All transactions on a blockchain are visible to anyone on the network. The entire history of transactions is publicly auditable. This means their transaction data can be publicly and thoroughly examined, verified, and scrutinized by any auditor or oversight entity at any time.
This increases accountability and trust without third parties.
Secure
Blockchain uses cryptographic techniques to secure the network. Cryptography is a complex mathematical algorithm that acts as a firewall for attacks.
Every piece of information on the blockchain is hashed cryptographically. In simple terms, the information on the network hides the true nature of the data, reducing risk of hacking or corruption.
No third parties
The decentralized nature of the blockchain ensures that no third parties are needed when carrying out transactions. Transactions occur directly between participants on a blockchain network without the need for verification by a third party. This reduces costs and bypasses institutional control.
Consensus
Consensus is a critical mechanism that allows blockchains to achieve agreement on the state of data recorded on the distributed ledger.
In a blockchain network, multiple nodes (computers) maintain copies of the transaction ledger. When a new transaction needs to be added, the nodes must reach a consensus on the validity of that transaction before it can be appended to the chain.
Blockchain Use Cases in the Real World
While blockchain technology works extremely well for Bitcoin and other cryptocurrencies, there are many other useful applications in the industry. Some of these are:
- Energy
- Data storage
- Finance
- Retail
- Media and entertainment
