Secure and untampered voting. In centralized server (server in AWS), the gate keeper can tamper the voting records (UPDATE voting set your_champion_voting = 100). With smart contracts on top of Ethereum, that is impossible.

The important properties here are immutability, transparency and authentication. This could be done by a centralized server. For instance by keeping an append-only log with signed voting records which is regularly published, where each entry contains previous entry ID. Like git...

But how do you know that the centralized server does not override all records to tamper the evidence? Append-only log is useless if the actor choose to override all logs.

So you need a neutral third party to keep the records in case the centralized server does the malicious behaviour.

This can be done, I admit. But in a corrupt society, it is hard to find a neutral and trusted party.

Other way is using blockchain to record the logs and incentivize the miners to maintain the nodes. You can not bribe the cryptography.

There has gotta be an encryption enthusiast out there that can explain to me how secure multi-user private communications can occur in a decentralized web. Assuming the crypto was strong enough to guarantee privacy, how does an application automatically allow a user to transparently decrypt topics they’re invited to? Point to point trust seems relatively easy with asymmetric encryption but point to point to point to…

Privacy is not a feature of Etherium or "smart contracts". It's the opposite, in fact. All transactions are public. The only "private" aspect is your address used to make a transaction but it has the same problem as Bitcoin in that regard: When you turn it back into real money your identity can now be attached to that address.

Is there a notification feature I can enable on HN to tell me when I get a reply?

Anyways, yes I completely agree with you, privacy is not a feature. Decentralization in general suffers from the inability to manage privacy and I think that’s where future applications of the technology are going to struggle to gain traction beyond niche audiences.
