I'm having trouble seeing how you could have offline transactions that prevent doublespending. Could you expand on "nice physical gauge theory (allowing offline transactions)?"
If you have a good idea here, it might be possible to implement as a second layer on a chain with smart contracts.
- knuthsat 6y agoI'm aware of approaches similar to this: https://gist.github.com/DavidBurkett/32e33835b03f9101666690b7d6185203 https://gist.github.com/DavidBurkett/32e33835b03f9101666690b... describing offline transactions.
- dlubarov 6y agoThat title might be misleading; the doc is just about generating transactions without the sender and recipient needing to engage in an interactive protocol. It doesn't address double spending.
- DennisP 6y agoAh, so this is a thing just because mimblewimble's private transactions are interactive. Regular blockchain transactions are already non-interactive.
