Revokable Escrow Bitcoin Trade?

[Sage]

I remember hearing a badly recorded audio that suggested there was a way to do a trade with Bitcoins that could be revoked.

Kinda like a escrow deal.

Anyone heard of this?  Or how it's done?

You mean mutli-sig?

This was discussed for example here. The main two variants are to have the coins burned in case of disagreement, or to have a 2-of-3 transaction with an arbiter that decides in this case.

Burned as in, the coins are not spendable ever?  Seems like this would be lose/lose for everybody??

Either that or sent to a charity agreed upon in advance. Yes, it's lose/lose but the fact that each party can credibly threaten to execute it means neither will try to defraud the other, thus it will not be actually manifested. Sort of a small-scale MAD.
