Please share your thoughts with me. How would you explain "blockchain in 5 minutes" to someone who doesn't know anything about it? What is this technology about? `

Well the main thing is how we explain blockchain with new people. Some Blockchain user inviting other persons by telling them that this is like invest 1$ and get 2$ , 3$ or 5$ plan. Ofcourse there is value of investment purpose of blockchain. But i personally believe that this is wrong to explain in very first meet, instead of this i will prefer to elaborate the technology of blockchain such as decentralization, transparency and security.
