Blockchain for most people is the technology that drives Bitcoin, but the real potential of Blockchain is far beyond driving cryptocurrencies. It is a technology having admirers like Richard Branson and Bill Gates, and various insurance companies, as well as banks, are planning to implement this technology in their system.
With this article, you will get an insight into the mysterious world of Blockchain and understand what makes Blockchain so interesting.
What really is Blockchain?
Today, most people transact through a reliable middleman like a bank, but Blockchain allows direct connection between a consumer and supplier. The involvement of a third party is pulled out.
Blockchain uses cryptography for keeping the exchanges secure and a “digital ledger” or decentralized database of all the transactions provided. This digital ledger can’t be corrupted and the transaction carried out through it can be seen by everyone across the network.
In simple terms, Blockchain is a digital ledger having every transaction of a cryptocurrency recorded chronologically.
How Blockchain Works?
Blockchain keeps the details of digital currency’s every transaction, and this technology prevents the same cryptocurrency from being spent twice. To understand it better, you should read the following steps:
- A wanted the money to be sent to B.
- The transaction is done online and is represented as “block”.
- This block is broadcasted to each party present in the network.
- Then, the members of this network approve it as a valid transaction.
- This block is then added to the chain, and a transparent and indelible transaction record is provided.
- Finally, the money reaches B from A.
Why Blockchain is so important?
Blockchain with various advantages provides huge opportunities, especially for businesses. With the help of Blockchain, a system can be developed by businesses which are capable of functioning more efficiently and effectively. This technology can be used by businesses in various ways and some of the uses are as follows:
- Blockchain can be used to completely automate the legal agreements.
- Businesses can use Blockchain technology in verifying Supply Chain activities.
- This technology when used in businesses bring Accountability and Transparency.
- Transferring funds is easy and fast without the interference of a third party.
What is the future of Blockchain?
In future, Blockchain technology will dominate the financial activities. Being a trackable global currency and having a well-organized infrastructure, Blockchain technology will result in huge cost reduction thereby benefitting each market participant. Moreover, the face of global banking will change and the payments will be carried out like emails are used today to communicate.
Is Blockchain technology secure?
Yes, Blockchain technology is secure and cryptography is the basis of this. All the records of a Blockchain transaction are secured by cryptography, and every transaction is connected with the chain of previous records or transactions. Moreover, the records of these transactions are distributed amongst and can be viewed by every participant of the Blockchain’s distributed ledger. Tampering that data is not possible because the hacker will be required to change all previous records in Blockchain.
These are some basics of Blockchain which might have definitely enlightened you with the basics of Blockchain technology.
