Blockchain is series of chain of blocks which contains data and it is tamper-proof I e unhackable it's a property which makes it so powerful. It is based on two principles---1.cryptography ---2.distrubutive technology + +2.what is the core problem blockchain trying to solve? +As data is the most important for any company so making it centralized makes it more towards hacking so blockchain provides decentralized platform +It also solves the problem of double spending +It also makes it unhackable +It also works on authenticity of data + +3. What are the few features which blockchain will give you? +Ans +.1. Immutable data + 2.decentralisation +3.transparency across users +4.tamper-proof data + +4.what all things does a block contain? +Ans. Own hash number--previous hash number---time stamp---data--mining key + +5.how is the verifiability of blockchain been attained? +Ans. Firstly it is a series of cryptographic hashes so one change can change all the hashes so it is difficult to tamper. +Secondly it is distributed ledger which means everyone will have a copy of data so if we will delete it or our data is lost we can take same copy from others. + + +○○ From 96ae46b0f31704a54b8c8c334e587d13879697bc Mon Sep 17 00:00:00 2001 From: prabhpreet singh Date: Tue, 13 Oct 2020 15:42:46 +0530 Subject: [PATCH 3/3] done committed --- README.md | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/README.md b/README.md index 98a356a..c7784a3 100644 --- a/README.md +++ b/README.md @@ -1 +1,5 @@ # Blockchain-Essentials + +## Read about blockchain as much as possible + +**The technology that will change this world!!**
