As a hard example consider the typical crowdfunding protocol. The contract (in english) is roughly: if this campaign hits goal before a deadline passes, all the backers pledge their money; or if the deadline comes before hitting the goal the money is returned to backers. In today's world we rely on kickstarter programs or staff, credit cards and banking. Codified using a smart contract these rules can be executed aut…
>if this campaign hits goal before a deadline passes, all the backers pledge their money; or if the deadline comes before hitting the goal the money is returned to backers. Let's pretend the campaign hits its goal and gets all the funding. There are still a number of breaches that can occur after the fact at which point the contract/math/programming is not going to be able to enforce anything one way or the other. Fo…
In my example there wouldn't be any room for a CC chargeback because we can assume all of the transactions are denoted in ETH itself. This is one of the qualities that enable the smart contracts to transact currency automatically. The programming language used to codify the smart contracts includes primitives to transact ETH.
The possibility of a minor transacting is interesting and I know there has been some discussion on implementing an identity framework on Ethereum (https://github.com/tradle/about/wiki/Identity-on-Ethereum). One can imagine then a contract which further limits participants by age.
I think you'll find though that many early adopter/enthusiasts don't care about age or jurisdiction. It's not obvious why US law should apply.
As a thought experiment though, I should ask about the properties which US courts hold that enable them to enforce contracts. Ultimately doesn't it come down to a court order, which if ignored ends in garnishment, imprisonment, or worse?
In theory, in a blockchain-enabled contract world, garnishments would either no longer be necessary or could automatically be enforced.
At the scary extreme you could even imagine a future where security drones owned by the "Sovereign State of Etheria" which fly around enforcing smart contracts with hunt/capture/kill orders. Slock.it is the most popular example bridging the real world/IoT with a DAO. And would this really be altogether different from how contracts are enforced manually in egregious cases?
I'm not stating any of this is good or bad, I'm just illustrating what is possible now and imagining what is conceivably possible in the future. I don't have a position in Ethereum (never owned any) nor The DAO, and I'm certainly not "marketing smart contracts". But you seem to insist that none of this is possible for some reason, and from what I can tell it certainly is.
If my interpretation of anything I've read about the technology is wrong though, I'd appreciate the corrections.
To find some common ground we should be able to agree on: how many contracts end up in litigation because one or both parties misinterpret the language of the agreement? Wouldn't it be desirable if there was a system that left no room for misinterpretation?
