I am a noob. Want to understand things. Is it possible to make a website which is somehow using blockchain and thus avoiding the DDOS?
What type of website? There are technologies like IPFS or Ethereum's Swarm file system that could certainly help mitigate DDOS by making the content p2p. So, you'd put the content into IPFS, and push a link in a transaction in the blockchain- and that link could never die, and without DDOSing every single node in IPFS (or Ethereum) that content would be available- potentially even off the internet in a LAN environment.
But that does come with restrictions- it's immutable once added to the filesystem- it would require basically a new commit to IPFS and new link each time you updated it. The biggest issue you'd hit is if you wanted it to be a HTTP protocol accessible website, you'd need to create an 'Oracle'- a service that would go find the latest IPFS link and display that as a website. Said Oracle would be very susceptible to a DDOS attack- so it becomes a single point of failure. This is changing, there is work still ongoing but the holy grail of a DDOS proof endpoint that's easy to access isn't quite there yet.
