What is the most ancient concept of blockchain in our life?
The easiest way to understand a concept of decentralized itself is RELIGION. Religion doesn't have a center of place, company, and people who run it. it cannot be destructed by physically and Religion has its own system. but it can be replaced with a better idea. Same thing with blockchain itself.
I hope people aware of the importance of blockchain and not just cryptocurrency as a medium for investing or trading.
please share your thought and kindly correct me if I'm wrong.
You are a good example of a noob who doesn't understand blockchain at all, yet reveres it as something truly great and world-changing. Blockchain is immutable, append-only database that should be used by parties that don't trust each other to eliminate cheating. Your comparison with religion is completely way off, because organazied religions are pretty centralized, they have small groups of highest priests that make all the important decisions. Religion is not a database, and it's not immutable - old religions are forgotten and the new ones take their place - but in blockchain nothing is forgotten, new data is written on top of old data, and old data is never deleted.
