>and it neither invalidates the original proposed solution nor lessens its usefulness

Yes, you're right that by itself it doesn't invalidate the proposed solution. Aside from that, blockchains are still useless and that's what invalidates it. They don't do anything meaningful. Any blockchain-based solution is useful in spite of the blockchain, not because of it. I've never seen any use of blockchains to disprove this.

>Blockchains create a completely transparent, decentralized ledger.

No they don't, in theory they could do that if everything was perfect and if we didn't have to deal with the other side effects of open trade and capitalism, but in practice they don't. Every blockchain I've seen is heavily manipulated by private interests and has serious problems with centralized control. And those are just the big L1 chains. It only gets worse when you consider side chains, a lot of those have no attempt at providing transparency or decentralization at all and it's evident they're privately controlled by one company or group.

>If you don't see any novelty or potential value in that, then that's fine.

I agree there's novelty in it, but that's about it. There's no practical value whatsoever, current or potential. They're useless. I've been pretty consistent about this for the last year. Personally I humored crypto enthusiasts for the last 10 years before this and I listened to as many of their pitches as I could, I tried to look high and low for the good in it, but it's just not there. Enough is enough. It's all bad and nothing meaningful has been accomplished. There's no practical uses of this technology. However it is a very big lightning rod for scammers and fraud.



I am pretty anti-crypto generally but I feel compelled to reply to your maximalist position that there is "no practical value whatsoever, current or potential" to blockchains. The one use case I have seen for blockchain that is real is that cryptocurrency is great for moving money around the world when governments or banks maybe don't want you to do so. At the very least the experience of sending crypto is about as annoying or a little bit less annoying than sending a wire, and you can avoid all those pesky AML/KYC requirements that banks and payment processors impose.

I am not suggesting that this isn't ethically fraught -- of course it is. But one can imagine uses. I personally have known a couple people who fled Syria during the civil war, and bitcoin was a useful way to pull money out of the country, and much less dangerous than carrying a suitcase of cash.


But isn't this awfully close to saying: Blockchains/Cryptocurrencies are useful exactly for money laundering and sanction busting? And ... saying that publicly _and_ supporting the implementation tends to go very badly. (As it should imo, but that's a different story).

IF that is the summary conclusion to crypto (which I'm currently holding), then this is pretty close to "no practical value whatsoever", isn't it?

Yup.

> And ... saying that publicly _and_ supporting the implementation tends to go very badly. (As it should imo, but that's a different story).

Good. (I don't support the implementation.)

> IF that is the summary conclusion to crypto (which I'm currently holding), then this is pretty close to "no practical value whatsoever", isn't it?

For ordinary people who don't need such services, yes.


>The one use case I have seen for blockchain that is real is that cryptocurrency is great for moving money around the world when governments or banks maybe don't want you to do so.

No it isn't. You don't need blockchains to create illegal banks and exchanges or to launder money. All of that was around for a long time before blockchains. You could even create those things "as a service" without blockchains, it would be just as shady and illegal. I'm serious here, there is absolutely no practical value to blockchains whatsoever.


This is like saying you don't need a car to get downtown. It's true, of course, but it's not interesting.
