> Consensus is only really nessisary for solving problems like payments or namespacing (e.g. namecoin)
Those are the only credible use-case(s) that the cryptocurrency folks should be looking at. I can see a few projects surviving like Stellar [0], Ripple (XRP) [1], Algorand [2] and Nano [3], ENS [4], Handshake [5] and Skiff [6].
Unlike the other projects that are slapping blockchain, crypto on to anything they can find and are filled with scams being reported, daily on web3isgoinggreat, there are a few that are not silly meme coins / tokens, or vaporware but stuck to their goals / whitepaper(s) and seem to be still useful and have a use-case.
This is what these skeptics won't tell you and will ignore and filter out.
I’m familiar with some of these, and yes they are the less scammy and more serious projects.
Bitcoin itself was a genuine attempt at peer to peer cash too.
Problem is the technology sucks and can’t scale. The trade offs are immense. DNS works great and is decentralised in all the meaningful ways. Nano network is currently struggling cos of one script kiddie, and puts everyone’s bank balance out there for the world to see.
Honest intentions and even innovative ideas are all well and good. But replacing the current financial system, or DNS or whatever is a massive technical challenge.
The trade offs in efficiency, scalability, even privacy with blockchain solutions, just to get decentralisation, are far too high.
Algorand was the first blockchain I ever used without knowing it - to hold the results of games on the official FIDE chess online tournaments - and I found that pretty cool. No costs etc, just a log on the chain with my matches and scores. This is coming from someone who spent 18 months working on Cardano, too.
