The origin of internet is as old as computers, dating back to 1950s. As other evolutionary technologies, internet to evolved from basics like networking, making headways to complicated protocols. It grew as an empowerment today, as a lifeline of communication, business and daily necessities for billions around the globe. Internet is now the crux of technology, which transformed as the foundation of many other dimensions like Big Data, Cloud Computing and most recently, Blockchain based solutions.
While Big Data and Cloud Computing evolved as massive technological disruptions, Blockchain is now evolving as a significant facelift of internet. Although, the technology gained initial popularity as the basis of cryptocurrency, its metamorphosis as the future of internet application is taking shape eventually.
Blockchain technology is only a decade old, supposedly originating in Japan. As records mention, Blockchain was invented by Satoshi Nakamoto as a public ledger system to store the currency called Bitcoin. The latter is basically a digital asset and a medium of exchange. It is the first among Blockchain based solutions. This digital asset uses strong cryptography to secure its transactions, hence, gaining the moniker as Cryptocurrency.
Blockchain is a solution to a pertinent problem in digital cash transaction called Double Spending. It is possible to corrupt a digital token by duplicating its underlying digital files. Such duplicate tokens can let online transactions occur multiple times for the same amount of money, creating fake records of new currencies. It is similar to creation of counterfeit money in physical world.
Prevention of Double Spending has two approaches: Centralization and Decentralization. In Centralization, a third party verifies if a token is on use. In Decentralization, strong cryptographic techniques create a system of distributed-ledgers. This system of distributed-ledgers is Blockchain.
On the onset of Blockchain’s popularity, a general understanding of the technology is necessary. A key aspect is its comprehension in the light of Internet. While Blockchain is different from how internet works, it is not different from internet, in terms of its origin or existance. Blockchain is different, but not separate from Internet. So how Blockchain based solutions are different from internet?
Applications on internet are centralized, but decentralization is the basic aspect of Blockchain. Centralized servers store everything on internet., Servers are physical devices that store digital information. Wired or wireless connection connects them to devices creating the vast network of internet.
In contrast, Blockchain does not need centralized servers because, here information is distributed across the network equally. It is a peer-to-peer network creating a distributed computing system. Information of any transaction is in each ledger, which are individual blocks in the network. This is the primary difference between Internet and Blockchain.
However, Blockchain does not exist separately from internet. It is a section of internet that is secured cryptographically so that the information distributed in the system is accessible only to its exclusive users.
The basic features of decentralization and cryptography provide many unique characteristics to Blockchain technology. The major facets of Blockchain are immutability, being anonymous yet public and constant verifications.
There are other facets making Blockchain a unique technology. Verification of transactions does not need any third party, blockchain based solutions are open to anybody and it does not require any permission to enter a public distributed system. These aspects are basically contrasting to that of internet.
With several special features, Blockchain based solutions are now emerging as an alternative to conventional internet applications. Industries are gradually adopting Blockchain technology for its ingrained advantages. It evolved much more than being only a cryptocurrency. Apart from corporate sector, public sectors are also using this actively. Several advanced countries are now implementing Blockchain as public utilities.
The shift from conventional internet applications to blockchain based applications is drastic. Blockchain is imminent in current as well as in the upcoming landscape of technology.
