Our team, @EOS9CAT came with a very short explanation for Blockchain and hope it would be helpful for everyone here.
The blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. 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).
