I'll answer in order: That's a great point! The solution is to add a timelock, just like an HTLC. This coin is only spendable with a signature from this pubkey until time T at which point it is redeemable by anyone with only the proofs. So if Alice locks some coins to Bob's pubkey then only Bob can redeem those tokens within the time window. After T, either party can redeem them. Alice has essentially locked herself out until time T. I believe this is the default flow, although I haven't verified it myself. I'd love to try it out if you're interested. I don't understand your point. All cashu mints are lightning nodes. You can transfer the coins with a lightning transaction. The privacy properties of ecash ensure that mints must honor lightning withdrawals for everyone or suffer reputational damage from everyone. Sometimes it's buggy. You can usually recover from your seed phrase to get those tokens back. This will improve in time as the protocol matures. Do you remember the early days of lightning? #reckless Yes, exactly! It is a continuous rug. Further reading: https://gist.github.com/callebtc/ed5228d1d8cbaade0104db5d1cf63939

You didn't ask me but I think Spillman channels are going to be a very fruitful field of development to replace the shaky security foundation of lightning with stronger guarantees for onramps and offramps. Let the node operators assume the game theory risk in their channels, but the users need rock solid unilateral exit. If you build a wallet with Spillman channels I'll be very impressed. Now we're finally improving on the lightning security model. But that's just like my opinion, man...

Ecash is about a million percent more private than custodial lightning. All other use cases are either improved by the privacy properties or fall back to lightning baseline performance. Examples: 1. "someone can promise a token is yours" no, actually the mint makes a cryptographically verifiable promise that the token is only claimable by the entity holding the correct private key. This is better than custodial lightning because they don't know your identity so they cannot selectively enforce these contracts. It's very possible to build some kind of staking/slashing mechanism or web of trust if you think reputation alone is not sufficient. It seems like this is a core feature of your proposal. It can applied to mints just as easily as custodial LN wallets. 1a. "a promise is all it amounts to until you get online and talk to the mint" no, you need to know the mint's public key beforehand and have some trust in that mint. In this case you can cryptographically verify the promise from a trusted party. If you don't already trust the mint then it reverts to the custodial lightning trust-me-bro model. 2. "Coins aren't fungible across mints" mints are connected via the lightning network so all it takes is a lightning transaction to reissue at another mint. Many wallets let you configure this automatically so you never even accept tokens from an untrusted mint. Personally, I think the endgame is to have mints directly swap each other's tokens but the cashu team has pushed back on this idea. We'll see where we land in time. IMO it's an obvious scaling strategy. I think we'll build it when demand is apparent, maybe as part of a different ecash protocol. 3. "There's also some parts of the process where you might lose the coin altogether?" yeah just like losing your lightning signing keys. Cashu uses deterministic secrets with a 12 word recovery seed phrase so you can recover your coins if you drop your phone in the toilet. This is equivalent to lightning. You should look at the spec, you have knowledge gaps for big important protocol features. 4. "The only way for an operator, even an honest one, to stop is to rug everyone." this is true today. I think we have to build expiring ecash to solve this problem. This is an inherent feature in ehash so I'll probably be the first to build it. Mining shares have a TTL, they are only valuable in a limited time window so if you wait too long they become worthless. Easy to enforce with a TTL on the token. Extend this functionality to bitcoin backed ecash and you end up with the same UX as ark: wallets have to periodically come online to refresh their balance. I skimmed your proposal. I don't understand it yet but on the surface it seems to be 1. lacking in user privacy and 2. have an optimistic game theoretic security model. Current DOR lightning channels rely on optimistic game theory and the security problems are manifold. They do the best they can to minimize failures but the attack surface is just so large. This is why LN-symmetry is such a huge upgrade. Game theory is a weak foundation to build on IMO. This proposal seems like a strict downgrade from ecash. You still have to trust someone and the user has zero privacy from the operator. (Correct me if I'm wrong.)

Yeah I think it will dominate microtransactions. This is exciting to me because we have never really been able to explore this frontier. The tech has always been too shitty. You're totally right. Don't keep large amounts or long term funds in ecash. I would turn your question back and ask why the constant dismissal of ecash? People's reaction seems completely out of proportion to the threat. I'm not talking about you specifically but it's a very common sentiment among bitcoiners.

what brigading? ecash is exciting because it can do things more complicated networks cannot do

yeah it sounds unnecessarily painful
