Blockchain Features
Blockchain technology is a distributed system of storing data across multiple networks. What makes blockchain different?Below, we’ll look at 5 of its most important features:
- Decentralization
- Immutability
- Enhanced Security
- Consensus
- Quick Settlement
Decentralization
The first detail to note about the Blockchain is that it’s based on the principle of decentralization. The system doesn’t depend on one person or group to keep it running.
Think about your Visa or Mastercard for a second. This debit card allows you to pay for goods and services online without having access to your bank account. If your MasterCard is stolen or the central network is breached, you could lose access to your funds or have your privacy compromised.
Instead of having a single data storage (repository) or information, every blockchain network comprises a distributed bed of connected computers. These systems are situated in different parts of the world. This makes it difficult for a cybercriminal to cripple the network, as each computer retains the records of the network.
Also, the lack of an intermediary creates a transparent profile, as every update on the Blockchain is viewable by every participant in the network.
Immutability
Another important attribute of the Blockchain is immutability. This is one of the key features of the technology, which means that it can’t be changed, edited, or overwritten.
Immutability refers to the ability of the ledger to remain a permanent and unalterable history of data. For instance, you expect safety and security if you store your work files on a third-party service on the internet. But what happens when the platform experiences a security breach? What happens when cyber criminals access your data? Can they delete it? Can they alter it in any way? Sure, they can, but not on the blockchain.
Systems built on the Blockchain can guarantee complete data integrity and a fraud prevention system. Since the data stored on the Blockchain can’t be tampered with, it also increases the auditing process and efficiencies for the users.
Enhanced Security
Very important thing that makes blockchain different from other networks is the safety of files stored. To secure its framework, blockchain protocols rely on cryptography.
Cryptography is one of the oldest forms of securing sensitive information. It dates back to the Ancient Greeks. Since then, it has advanced a great deal. Cryptography is the process of protecting information through the use of codes. The main goal is to ensure that only the intended recipient of a message can view the contents – not a third party.
Cryptography involves encryption, decryption, cypher and a key. Encryption converts readable texts to an unreadable sequence. Decryption transforms the encrypted data into readable texts. The Key locks and unlocks the data via an algorithm or system called the Cipher.
Blockchain primarily relies on cryptography to enhance the security and integrity of the network. For instance, the Bitcoin blockchain uses a key system to encrypt and decrypt transactions. The sender signs off and encrypts the transaction with a key, which is then unlocked and claimed by the recipient’s private key.
Each participant in a Bitcoin transaction owns a pair of keys known only to both parties. The sender encrypts the transaction with their key and safely passes it on to the recipient. Only the recipient can unlock and receive the transaction using the other key in their possession.
Consensus
The idea of consensus is another important aspect of the blockchain. Since the blockchain ledger is decentralized, there’s no need for a middleman or central figure to decide what info should be added or excluded from the network. In reality, they don’t need one. The nodes in a network only need a set of agreements to do so. Nodes are computers that store the complete record of the blockchain.This agreement between the nodes operating on a network defines what Consensus is about.
Consensus is the ability of a group of individuals or computers, in this case, to agree unanimously on a particular issue.Therefore, all computers on the blockchain are governed by consensus when adding new data to the network.
Consensus is useful in storing data in the blockchain. Before a blockchain is updated with a new transaction, an agreement about the transaction’s correctness or validity must be reached. If more than half of the nodes vote to include, the transaction is added. Otherwise, it’s deleted.
More often than not, computers are incentivised to act honestly rather than act maliciously. For instance, Bitcoin rewards miners who verify transactions and add them to the blockchain with 6.25 Bitcoins.
Quick Settlement
Traditional banking systems are usually slow; transactions can take several days to be confirmed and received. Blockchain technology is helping to solve this problem because it confirms transactions faster. This is due to the elimination of a middleman.
Transactions are only initiated between two parties, reducing the need for a third party to vet them. With only a few participants involved, transactions are processed faster.
Cross-border payments can now be completed in minutes and at most an hour instead of waiting days for value to be sent and received. Blockchain protocols like Solana and Polygon process thousands of transactions in seconds, and the beautiful thing about it is that the fees are nearly nonexistent.
Conclusion
All these features make the technology unique. Experts believe that blockchain technology could help change how finance is handled in the future. Blockchain is here to stay because it has a faster payment system, high-security levels, no central entity, and can’t be hacked.
