What is Blockchain Technology?

Blockchain Technology is an advanced method to input data. It conversely registers information. Also, the input data cannot be changed, hacked or manipulated. It also protects and safeguards the data. Due to digitalisation, the high increase in the use of cryptocurrencies has led to the advancement of Blockchain.

It records the financial statements and transactions done across various computers. Accordingly, this technology provides complete transparency and security. Moreover, it consists of chains of blocks. The core feature of this technology is that once a block is added to the chain, it cannot be changed.

Features of Blockchain

The unique mechanism of this technology is what makes it different and more useful as compared to other systems. It has several features that generally make it beneficial to us. They are as follows:

Features:

1. Security: To secure the input, it uses up-to-date cryptographic methods. It makes the data impenetrable from any other unknown sources. This protects the input data from hacking. It also makes it resistant
2. Transparency: All the data stored using blockchain technology is visible to all the personnel involved. This helps to ensure transparency among users. This feature is especially beneficial to record transactions.
3. Permanent Ledger: As soon as one records data using this technology, it is impossible to change. No alterations are possible in the data after adding a block. This helps to provide permanent and secure data.
4. Decentralization: Blockchain promotes decentralization. The computers around the world run it. It means that no person has complete control of the information. This proves to be beneficial to users. It also helps to promote complete security.
5. Permission: Blockchain also has a feature of permission and permissionless. ‘Permissioned’ are private and they are inaccessible. Whereas, ‘Permissionless’ are accessible to anyone. This feature makes it possible to cater different needs of the user.
6. Privacy: Blockchain is famous for its transparent transactions. However, it also provides several features to ensure privacy.
7. E-Signature: To ensure that the transactions are valid, blockchain uses e-signature to verify its authenticity. This feature helps to assure security.
8. Accessibility: Due to constant advancement in the field, blockchain has become especially accessible. This feature is helpful to a wide range of audiences. There is a variety of different types of accessibility provided by blockchain. This proves to be beneficial.

How does Blockchain work?

Blockchain Technology is a highly advanced technique. It ensures transparency and security. It helps to protect the input data from hacking, manipulation or external changes.

Once information is recorded and authenticated by the software, a block is created. It is not possible to change or manipulate this block further. Moreover, this block is shared with all computer blockchain networks that are connected to the blockchain. They are worldwide.

Scope of Blockchain

Blockchain has already become a disruptor in many industries. As it provides beneficial features and also ensures security and transparency. This technology will spread more in the future. It is also already in use for cryptocurrencies. However, several other sectors and fields require extreme transparency and security. Moreover, Blockchain can help to establish these attributes skillfully. This can certainly help in increasing the quality of the functioning of these sectors much more proficiently.

Some sectors are as follows:

• Transparent voting system
• Healthcare industry
• To verify identity
• Copyright
• International trade
• Financial Sector

Choosing a career in blockchain can be extremely beneficial, as it has a bright future ahead. There are abundant career and learning opportunities in this field, with a high scope for salaries as well. Blockchain technology is in demand and it will rise further.

Pros and Cons

Blockchain is a high-level and complex technology. Though it has several beneficial features, it also has some drawbacks.

Pros:

• Worldwide Accessible: Blockchain certainly promotes transparency. Moreover, it is accessible to everyone worldwide. It also helps to easily participate in global transactions.
• Smart Contracts: Smart Contracts work automatically. It executes automatically once the conditions are met. However, they are not legalized.
• Immutability: It ensures that it cannot be altered once data is recorded. This also helps to protect the input.
• Traceability: It can trace the connection or movement of the resource. Therefore, ensuring the transparency of the network chain.

Cons:

• Environmental Conflict: Some Blockchain like Bitcoin use Proof of Work (POW). This consensus mechanism requires a great deal of energy to function. This can create environmental hazards.
• Complicated System: Blockchain Technology may be complex for certain individuals. It can be demanding.
• Permanent Transactions: As permanent transactions are one of the key features of Blockchain, it can also be a drawback. Records with errors or some other problems cannot be undone.
• High-cost Expenditure: Due to Blockchain’s advanced technology, it is also costly. Development of such technology can be difficult due to its high-cost expenditure.
