Blockchain Technology Explained, What is Blockchain Technology?
What is Blockchain Technology? It is a new type of internet that allows digital information to be distributed but not copied. Gartner refers to blockchain technology as a part of “the programmable economy” – the one where all movements of assets and value between organizations or individuals are managed through a blockchain. “The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value.” Alex Tapscott – CEO of NextBlock Global & Co-Author of “Blockchain Revolution”

What Problem Does Blockchain Solve While conducting business, trust is a fundamental element that allows two parties to engage in an agreement for exchanging value. The most popular methods that build trust between two parties engaging in an agreement were resorting to banks, insurance companies, judicial and legislative system, fiat money, bonds, stocks and contracts. For example, when a user pays for online purchase through credit card, the merchant is charged 2.5% of the transaction value. This is where blockchain technology comes into picture. As it is truly said by the expert Ginni Rometty, “What the internet did for communications, blockchain will do for trusted transactions.� – Ginni Rometty, CEO of IBM

Robustness of Blockchain Technology Blockchain is the next generation internet that comes with built-in robustness. It cannot be controlled by any single entity and thus does not have a single point of failure. Since its inception in 2008, blockchain has been in operation without any major disruption. All the problems that have erupted in blockchain network are intentionally planned, i.e. they were result of human interference and not occurring as a result of flaw in underlying concept. The robustness of blockchain isn’t challenged yet with a good track record as it still continues to be developed by researchers and experts

Robustness of Blockchain Technology “As revolutionary as it sounds, Blockchain truly is a mechanism to bring everyone to the highest degree of accountability. No more missed transactions, human or machine errors, or even an exchange that was not done with the consent of the parties involved. Above anything else, the most critical area where Blockchain helps is to guarantee the validity of a transaction by recording it not only on a main register but a connected distributed system of registers, all of which are connected through a secure validation mechanism.” – Ian Khan, TEDx Speaker, Author & Technology Futurist

Secured and Transparent Blockchain Network Blockchain technology is quite secured as the distributed network is build such that it checks in with itself every ten minutes. This kind of established self-auditing ecosystem defines digital value and reconciles transactions happening at frequent intervals of time. All the data is public and embedded within the network to account for transparency of transactions. Further, all the data or every unit of information in the blockchain network is secured and cannot be corrupted.

Permissioned Blockchain Network Blockchain technology is an ingenious invention and brainchild of a single person or group of people known by the name ‘Satoshi Nakamoto’. It stores blocks of information that are identical across the network. However, some people are still sceptical of how secure are the transactions carried over this network. This insecurity has given rise to the concept of ‘permissioned blockchain network’. To explain in short, permissioned blockchain is a network for enterprises who wish to have better control over the mechanism, authenticate who is joining the network and control what type of access the participant should have over the network.

Purpose of Permissioned Blockchain Some enterprises find it critical to restrict access and usage, i.e. who can join the network or make change to the ledger. In this limited access network of permissioned blockchain, it can be ensured that information is traded only with those organizations that have been highly vetted by a chosen central authority.

Future of Blockchain Technology Blockchain is still in the budding stage, though its usage is already widespread right from the early phase. Experts look at Blockchain as the next generation and most revolutionary technology having the capability to redefine the usage of Internet. Some companies have already started using blockchain technology for business transactions.
