Asset Transfer Protocol #570

Open TelegramSam opened 3 years ago

TelegramSam commented 3 years ago

I'm curious if anybody has any work or design into a protocol for asset transfer? I'm studying a need to gather signatures on a transfer agreement between two parties. The end result should be a signed receipt that both parties retain, but not necessarily transfer the asset itself. The receipt can then be used (outside the protocol) to prove asset transfer. Payment is not necessarily required within the protocol either, though that would be a great future addition.

Anybody have work here willing to share, or interested in collaborating?

Not working on that use case, but we had a demo from folks at Ayanworks on a protocol to sign an attachment -- notably an Indy author requesting a signature by an endorser. The signing protocol part of that might be helpful in what you are doing.

@TelegramSam I am about to start working on something similar to this and would love to collaborate. Our use case is to have both parties sign a transfer agreement with receipts given to both and then allow that same asset to be transferred again to another participant. i'll ping you on rocketchat/slack today

The above protocol @swcurran mentioned is documented here: https://hackmd.io/5LzMhfsMQBevB5V2tKz4hA?view in the Please Sign This protocol
