We have all heard that Blockchain is essentially a virtual ledger shared  over a distributed database. 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 greater probability of an asteroid taking down this planet than a good blockchains 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.) The  fact  is that as long as you can get your hands on the coins without the   owners permission, it would be called hacking. 

The blockchain can theoretically  be hacked  in a number of ways, but most common hacking attacks include,  Sybil  attack, Routing attack, DDOS, etc. Their is one truth of hacking - theoretically, everything is hackable. 

You'll find that blockchain hasn't put an end to hacking. In fact it has even inspired some new ways of disrupting the network or trying to control the consensus. Nevertheless, the blockchains are still some of the most secure locations to keep your money in form of tokens (both fungible and non-fungible). Keep in mind that protecting the keys and passwords to access these tokens is each individuals personal responsibility. 

Here is the summary of things that have made the community at large interested in the Blockchain:

• Blockchain is censorship resistant
• Cryptographically secure
• Immutable
• Above all, it can be decentralized.
• Secure tokenization
