Interesting work! I should be fortunate to make time to read it. I will point out, in case you'd not considered it, that you can support addition and removal indirectly by formulating it as a difference of sets. Similar to the collision-resistant replicated data types (CRDTs) concept. Checking for

Good morning ZmnSCPxj, The issues you point out are indeed important to note. Thank you for your wonderful feedback! * There is a practical limit to the number of UTXOs you would be willing to > receive in the swap. > * Every UTXO you receive increases the potential fee you have to pay to > spe

Good morning ZmnSCPxj, Thank you for your excellent feedback! Indeed, with a little protocol-level sugar so that the coins being swapped get paid out of different pubkeys. I read your article. Excellent idea on the randomized locktimes! I've still to read the details of what S6 amounts to but I'
