This means that all information exchange on it (including the financial transactions that are being generated) is continually being verified and stored on various nodes across the globe. So there is no one critical point of failure............kill one node and it'll survive in hundreds of others, even thousands. It
Not only is a blockchain secure from being taken down but it is protected by encryption so un-breachable that theoretically we have a better probability of an asteroid taking down this planet than blockchain encryption being cracked open. (There is a reason why hackers find a way around this rather than through this encryption. That is why the hacks and security breaches are by compromised passwords, bug exploitation, phishing, etc.)

This has created an air of mystery around the blockchain technology that is making it difficult for people to trust it.
For example you will never see the media mentioning that the Blockchain in context of being a distributed ledger or its nature as a database. Granted that this does makes it difficult to understand, but at the end of the day we need to demystify this for the people. It needs to be shown that Blockchain is not overhyped but the term is being overused in the wrong context
Here is the summary of things that have made the community at large interested in the Blockchain:
