What is blockchain technology?
A distributed database shared among nodes of a computer network, blockchain stores information electronically in a digital format. They help in maintaining a secure and decentralized record of transactions. It is a decentralized method of storing data, thus making sure that no single person has control. One of the main differences between a traditional database and a blockchain is how the data is structured.
In the case of blockchain, data is stored in groups known as blocks. Each block has a certain storage capacity, and when filled, it is closed and linked to the previously filled block. Thus, forming a chain of data. This guarantees the security of data records without the need for a third party. A database typically structures data in the form of tables as opposed to a blockchain. Each of these blocks is given a timestamp and forms an irreversible chain of data.

Benefits of blockchain
1. Secure transactions
One of the greatest benefits of blockchain is how secure the transactions are. Once a transaction is recorded, the authenticity is verified by the network. If this transaction is validated, it can then be added to a block in the blockchain. Since each block has a unique hash value, if it is edited in any way, the hash code changes. However, the hash code on the block does not change. Thus making it difficult to change any information on the blockchain without notice.
2. Decentralization
The information stored in a blockchain is not in a central location; it is copied and spread across a network of computers. Every computer on the network will get updated when a new block is added to the blockchain. Thus spreading the information across a network rather than a single database. Due to this, it is difficult to tamper with the data. A hacker would be able to gain access to a single copy rather than the entire network being compromised.
3. Efficiency
Let’s say you’re making a transaction through a central authority. It can take up to a few days for it to settle and for the transaction to be secure. This can be because of multiple factors such as working hours of the institution, time zone differences, cross-border trades, etc. In the case of a blockchain transaction, it works on all 365 days of the year and 24/7. Transactions are complete in as little as 10 minutes and can be considered as secure within a few hours.
4. Private transactions
Although there are several blockchain networks that have public databases, personal information about the users is not available. If a user has made a public transaction, their unique code is recorded on the blockchain. However, their personal information is not recorded. Thus, ensuring that transitions are sharing any confidential information.
Types of blockchain
There are several types of blockchain available today. Taking up blockchain courses will help you learn more about the different types.
1. Public blockchain
2. Private blockchain
3. Permissioned blockchain
4. Consortium blockchain
