Block Chain Technology - Moving from Centralized to Decentralized
A Beginner's perspective
"If you can't just explain it simple, you haven't understood it well enough." ---Albert Einstein
I want my understanding to be corrected by the experts in my group
"A blockchain is a digital file in which the same information is stored by all members of a community and updates are attached to the existing information in regular blocks of time so that each participant has all the information and does not have to rely on others.---Julian Hosp
It is one of the possible ways of generating consensus decentrally in the digital world. It is decentralized ledger technology where the same data is stored by a group of people who are the members of a community (Rather than one party maintaining/controlling the information - Lack of Trust) and the data is updated at some regular intervals (Time blocks) with the consensus of all or majority of the members of the community digitally. This new information block is attached to the previous information block cryptographically (Chaining of the blocks and hence the name). No one can tamper the information without the consensus of the community and hence no question of bluffing.
Major advantage, I perceive with this technology is "Transparency in the transactions and processes in an encrypted manner" thus resulting in Value creation for all the stakeholders in the chain. It looks like it can reduce fraud, corruption and other major ailments which happen to be the key traits of majority of people who are in power and who have accumulated wealth in quite less amount of time. Will that elite group of professionals be interested to curtail their power and increase transparency in the processes? Only time should tell.
Technologically there may be many challenges, but I tried to put my understanding from a layman's perspective so that everyone understands the basic concept of the latest disruption technology. Any more value addition from the group is welcome
