I am not new to bitcoin, I never meant to say that the transaction could be revoked, I just did not know you could put multiple outputs in a multi-sig transaction too.  Perhaps I phrased it wrong.


Thank you all though, you have been helpful

Regards

Hello

Thank you for your inputs. They are greatly appreciated. 

How hard would it be to enforce the commission? Illegal marketplaces can do whatever they want afaik, but is there any better way to implement the fees other than doing it as side transaction and just refunding them on every "failed" purchase?

Regards

Yes but, assuming one was building a site and wanted to implement it there, what else could go wrong beside alienating the average user or user screw-ups? (assuming everything is coded in well enough) 

I am sorry if this has been asked before, I am just trying to understand things better.

Thanks

 Hello,

I am a long time lurker here, and this is the first time I joined to make a post here. So here goes

Assume you wanted to create a site (shop, market, w/e) that were to use multisig transactions between peers to ensure optimum safety. (Alice, Bob, Shop cannot scam each other or run with the money)

What are the drawbacks on this, excluding user friendliness? I understand the question is quite broad, so there is no need to be exact to the detail on the answers here, but I just want to know, in general, what other problems would one face while solving the whole trust issue  with multisig addresses. (For example, it depends more on txid, would transac malleability problem hurt things etc.)

Appreciate any input.

Thanks
