Has anyone ever looked at the possibility for Monero outputs to be locked by oracles? Specifically, I mean suppose that a Monero output could be locked if a specified asset existed on eg: Ethereum, but could be unlocked if an Ethereum asset was burned or something

all the risks associated with trusting the lock to another chain's security aside of course, that's on the users of those outputs/locks to worry about not the rest of the monero network

Like, Monero nodes would also have to be Ethereum nodes?

Isn't this in essence what noot is working on with ETH<>XMR atomic swaps? I think the atomic swap idea could be modified to do what you're suggesting.

UkoeHB: that definitely isn't what I'm hoping for; maybe the Monero network could somehow lock an output that can only be transferred with some signed key issued by a contract/wallet on the Ethereum network?

or any network in theory, Ethereum is just the most obvious

I'm trying to think of more clever ways to allow wrapped assets than just putting native XMR in someone's wallet and trusting them (or their multisig partners) entirely

How would you even implement such a lock though? Can't be part of the on-chain tx data, because you'd have to rewrite the lock status

Maybe you could have an eth contract that signs a transaction to a unique viewkey/spendkey pair, and only reveals the spendkey to the desired party once the condition for "unlocking" has been met?

But that would require quite a messy handling of "unique" keypairs inside a wallet, plus some kind of zero-knowledge proof to prove that the contract will indeed reveal the correct spend key

(I'm not even sure if this makes sense)

fyi guys sorry i couldnt make this weeks meeting - some complications with my dad in the hospital on tuesday came up. everything is ok now

I really don't know how this could be configured well endor00 , I'm just thinking out loud

idk if there's a way for a message to be signed somehow to be able to unlock/transfer XMR where only a contract has the ability to do this, and only under certain conditions (eg: if a wrapped asset is burned). Yes you would be trusting the contract in a large sense. I also am not an expert on what contracts can even do.
