If it will exist?
As far as I can see, it could have:
As have discussed, the decentralized web is more suitable for private connection, some must known messages, infrastructure, etc.
What do you think of the decentralized web?
Yes. But for the decentralized web, they should work in a decentralized way. Maybe have slight differences.
Cryptography for privacy, and making it impossible to (globally) censor and silence individuals. Local censorships is almost impossible to avoid without going all fruitcake in on blockchain stuff, but global censorship needs to be impossible ...
Replications comes to mind - Not necessarily in blockchain stacks ...
Because it implies completely silencing somebody needs to touch way more people. Today you can just coerce Google's CEO, or Zuckerberg, and "shut off" a human being. If the data was replicated to thousands of servers, owned by thousands of individuals, it's highly unlikely everybody would "shut off" the individual. Free speech is a right, but it's not a right to have people listen to what you've got to say. Or to rephrase; "You have the right to speak, but I have the right to not having to listen to what you've got to say" ...
Decentralized web is not that you force everyone to listen to you, but you voice can not be muted, When someone want to see other's voice, he can not be missed.
The right to mute anyone is not right.
The freedom of speech is right for any free man.
Free speech is not what you want to hear, but people have the right to speak freely even it is false and offensive.
Don't we have most of these things in the current web already? I don't think many users will switch to something new just because it's decentralised. Why should they bother?
A new web needs a killer app that attracts people. So I guess one of the fundamentals will be asset transfer (money or anything). However we have a chicken/egg problem here: asset transfer is only possible for tokenized assets, but there's not much demand in b2c tokenization. Maybe we'll have to wait until b2b tokenization has taken place (it's already happening), then b2c will follow.
