Parent gives you an answer that is scoped to "divide incoming by half and send the halves to given addresses" and you criticizing that the answer doesn't cover all scopes you can come up with?

Him: "This baker makes bread rolls". you: "What about dark bread? What about non-bread items? What's his broker?"

_Red gave two examples of Ethereum applications.

SeckimJohn quite quickly showed why neither work. The are some niche digital uses, but not the ones people often tout.

Ethereum contracts basically break down at the point they need to interact with the real world.

[Brotkrumen]

The only thing seckimjohn showed is that contracts, paper or "smart", are only as good as they're written. Since contracts such as _red gave, "we are friends, this is our company, we share the EBT equally", exist right now, it's a perfectly realistic use case for a smart contract. Hell, I'd even do that for a small project.

Smart contracts being fixed and errors being exploitable is a valid criticism but it's not the be-all-end-all argument for them to have no real world applications.

[jackpeterfletch]

No its fundamental.

In the trust fund example, you cant stop the recipient trading their key or wallet early, as you have no way to verify the human holding it.

Unless you keep that access with some legal guardian. In which case your security still sits in the legal system, as it would if you just used a trust fund. So whats the point?

Again in the company example, it only works if you both observe that the coins mean shares in company. Which you can only really enforce with a legal agreement, but again, why not just have a legal agreement that says you split your share?

They completely breakdown at the physical barrier. Darknet markets only work because the seller doesnt control the market and has a deposit. But apart from that they can transact anonymously, that part has nothing to do with blockchain.

What's to stop someone from trading a normal trust fund away? The recipient can simply take out a loan with the trust as collateral.

[SeckinJohn]

how do you prove to the bank the non-existence of a clause that would void the trust if this is done(and noticed)?

the main point I tried to make above was this: in normal life there is the "human factor"; like, if you look at a situation, you can reasonably comment on whether it's a positive situation from an actor's perspective; whether the actors were engaging in fraudulent activity etc. In digital-only world, there is no such thing as "probable cause", "reasonable doubt" etc.

which makes the application of smart contracts to real life intractable(IMHO borderline impossible for complex situations for the near future[~10 years?]).

""smart", are only as good as they're written"

There are so many things that go into contracts that cannot be articulated in 'code' that this all hardly makes sense.

Employment contracts are long. Comp packages can be complex.

And we all live in countries with employment laws etc. that require these things anyhow.

I don't see any actual real-world cases for Eth contracts just yet.

[patrickk]

The earliest smart contracts will likely involve things that are relatively easy to verify, e.g. a bet that the price of ETH will be above X at Y date and time.

Ensuring that accurate, real-world data gets entered into the blockchain to enable broadly useful smart contracts is going to be an interesting area to monitor over the next few years.

Augur attempts to align people's incentives to accurately report on real world events, like political events (aka Oracles). Axa pays out on delayed flights with a new flight insurance product[1], from data gathered from public flight information, which triggers an automated payout.

"a bet that the price of ETH will be above X at Y date and time"

Not so fast. Who says 'what the price of ETH' is? There is no such thing as 'the price of ETH' - there are simply buyers and sellers each willing to sell and buy at different amounts.

You'd have to agree on a mechanism to agree on what that price even is.

And what about odd fluxuations? Market cheaters - i.e. getting a hold of a vast quantity of ETH just to jolt markets for a few hundred milliseconds just to jigger some contract?

As far as 'paying out on delayed flights' - that's a very cool idea, but I can't imagine why on earth it would be in ETH on a distributed ledger.

> There are so many things that go into contracts that cannot be articulated in 'code' that this all hardly makes sense.

I think this is actually something I've been trying to articulate for a while now anytime smart contracts come up.

Legal contracts only specify the criteria and conditions surrounding a contract. Smart contracts must describe that PLUS all the very specific instructions on how to validate those criteria/conditions which adds a massive amount of complexity into the contract (and more potential for loopholes).

[scandox]

Well I'm entirely new to this and pretty blockchain sceptical but I don't think SeckimJohn showed why neither work, did he?

As I understand it each concern requires some kind of function/method which addresses it within the smart contract, right? So the real problem is that once you publish the contract you better make sure you haven't forgotten something important...

[jackpeterfletch]

Basically both examples in order to work would need legal enforcement or guardianship outside of Ethereum.

Which they both need to work today anyway. So whats the point?

Until ether contracts can hold people to their word, are recognised by the judicial system (which wouldn't be able to effect it without some weird judge API), or is able to enforce some kind of judiciary process itsefl (SKYNET WARNING), they'll always break down at the physical barrier.

[wlll]

He didn't show that neither work, but the examples he did give were trivially bypassed and didn't seem "real world" at all.

For instance, I can't think of any corporate structures that splits income in half. Usually the money is run through the company and costs etc. are taken out first. So this isn't a real world example?

[Joeboy]

Right, the examples are just missing the step of "somehow make sure this isn't as bad an idea as it looks".
