You can program anything up to and including judicial oversight and interaction rescission into a smart contract.

I will not be able to convince someone who’s stubbornly ignoring everything I’m saying. Go waste someone else’s time.

You can mimic any existing setup for tracking deeds and similar, or invent new ones, with the added quality that they can’t be doctored.

What do they “make”? They control for the risks in social economic interaction with potentially adversarial parties. Ethereum is proof of stake, it doesn’t burn up tons of fossil fuels. And the contracts aren’t subject to human interpretation after being authored, they’re deterministic at the protocol level (save for the entire network deciding to revoke the contract).

Why are you making fundamental mischaracterizations of the technology while acting like an expert?

Yes, work. Smart contracts are designed, programmed and, if they’re done right, rigorously audited for correctness. Then you have user-facing interface and everything surrounding that as well.

Yes, for the limited subset of ERC20s or whatever you describe as “ponzicoins”. Things that actually do nothing, particular on top of L1 cryptos but “this is another token”, are not really adding any value. But I would be really surprised if you can name any more complex contracts than ERC20s, which is where the work in the space actually goes.

I reckon most of that already is. A real estate escrow smart contract is maybe 200-300 lines long in Solidity, depending of course on what it supports (contingencies and such).

“Greatest fool” description relies on the precept of its utility or demand returning to zero in a near-future timeframe. If people have utility for “the thing”, that won’t be the case.

Also they have some smart contract capabilities which I suppose Ethereum people think are important. But I’ve never seen any practical use for that stuff.

Anything you need complicated multi-party interactions for that you want guarantees on. Real estate escrow comes to mind first. Depository accounts with yield. Multi-signature corporate treasuries. Whatever. It’s programmable money.

According to…that woman with a book about his wealth? Article says 70 to 200 btw, not 200.
