Hi @meysam and Everyone,
Our team, @EOS9CAT came with a very short explanation and hope it would be helpful for everyone here.

It features decentralization, immutability, security, and openness, comparing to traditional distributed systems. the most symbolic adaptation of blockchain technology is cryptocurrency (bitcoin, ripple and various coins) and decentralized applications (Ethereum, EOS and etc).
