Blockchain can help prevent DDoS attacks
Several products such as #Blockstack, #Nebulis and #Maidsafe are facilitating the decentralisation of the Domain Name System (DNS).
This would make it much more difficult to launch attacks such as the one suffered by Dyn DNS.

“By using the Bitcoin blockchain to bind the name to a public key and DNS information, Blockstack allows anyone to register a name while simultaneously ensuring that only the name’s owner can control it."
“If the Dyn attackers wanted to knock websites offline in Blockstack, they would have to attack either the individual sites or attack the Bitcoin network itself. Even then, all the Dyn attackers could do is slow down name updates,”
Another project similar to the Blockstack vision is a platform called Nebulis, which uses Ethereal under the hood. [...] The difference is, this platform uses IPFS as a replacement for HTTP and utilizes the Ethereum blockchain for DNS capabilities.

Maidsafe focuses on removing centralised servers and creates an encrypted distributed framework across a peer-to-peer network.
