Hmm, I've never used it, but something like Silkroad worked, it did not have trust issues. To me it reads like they try to save pennies on customer support.

The differences between Silk Road and Airbnb is that the former didn't have lots of investors and techbros to pay returns to, so they could actually offer a fair escrow service and still remain profitable, where as Airbnb has to commit fraud by pitching you an "insurance" service that never actually pays out because doing so would lower or even negate the techbros' returns.

> It's fundamentally a problem of trust.

Absolutely. That's where bitcoin could help a new platform, as a decentralized trust protocol. The bisq.network protocol requires people to put up significant bonds to perform roles that are trusted, and then if they fail to perform well, they can loose some or all of their bond. The bisq token holders (bisq tokens are simply colored satoshis, i.e. they've built functional governance directly on bitcoin) vote monthly on various governance proposals, and can thus hold people doing bonded roles accountable.

The tough question is whether such a system could make to individual apartment rentals in the real world. Its an oracle question: how to you establish the truth of competing claimed about the state if an apartment? Not an easy problem to solve, but if its solveable it could provide an amazing new marketplace.
