I don’t know if I am missing the point here, but didn’t I just answer this? Just like UTXO sizes are metadata in Bitcoin. The solution: Make sure that your is the same size as everyone elses. Most CoinJoin impl. did this

well idk about you but i've always been bothered by the endless calle posts on twitter when i was there and now here i see it on nostr and NOTHING points these two points out: - denomination is metadata that the mint can link between spenders and redeemers - you should either use common denominations or use anonymizing proxies to do spending or redeeming now, are you going to tell me that is not disgustingly missing from the marketing of ecash, or are you going to back down?

Lmao… I can not back down, as I never made this claim. Do you realise the post was about comparing custodial Lightning with Cashu? With custodial Lightning you can not have privacy EVEN if you are using Tor. And claiming that @calle 👁️⚡👁️ would actively withhold this is just ridiculous…

what problems does ecash solve that lightning and bitcoin don't solve? then you see the problem i am pointing out they solve both problems, actually, and ecash solves a different problem synchrony anyway, carry on, i've unfollowed

in case anyone is reading my reply, the whole thing about bitcoin was as a solution for what CHAUM's ecash did not solve and lightning solves what SATOSHI did not solve with bitcoin is it any more clear how retarded the ecash bullshit is? unless they address the issues that BTC and LN solved already they are just shilling snake oil

Chaums ecash did not fly at least in part because nobody had solved the unconfiscatable, scarce digital commodity problem, there were no reliable sources of value on computers. That Bitcoin and Lightning were invented makes dipping in and out of ecash possible, and makes Chaumian ecash suddenly a useful tool and solution for different problems than BTC and LN. Its IMO (maybe even in its current highly beta state) at the very least useful for local meatspace or trusted networks where you have small transactions, interactions and need to keep score. Caution obviously should be taken with it, balances kept low and temporary and trust (between mint&user) is necessary and not minimized in chaumian ecash. Even with its drawbacks I think it could power the thriving of circular economies, it's quite a good replacement for normal cash or (trad)Bank-transactions. Maybe a bad analogy could help illustrate: if you have an induction furnace and an oven for cooking your meals inside in a safe, reliable and comfortable way where only major fuckups get you burned, you might still want to add a barbecue. Although its harder to get the meal right, you then have to be outside and are more likely to get burned or get wet a BBQ is still not a useless tool. I think its clear whats what in the analogy? For the right job, circumstances, and with proper handling, something which is otherwise not very good can be a delightful tool.

i hate induction heating, give me carbon fuel any day, it's very crappy tech and the devices use clunky, noisy circuits not the kind of smooth, dynamic algorithms i would design and that's not easy to translate to hardware without some heavy capacitors and arrays of capacitors and FETs etc anyhow, i'm not saying ecash isn't useful, but it has two big, clear, and obvious deficiencies that make the mint a trusted third party and if you don't use a limited set of denominations, totally identifiable metadata build some tools to fix those two problems, and both are related, and i'm in

all forms of electrical heating are based on magnetic force causing deformation in materials (almost always ferromagnetic) or electric force (such as through carbon) and they are highly inefficient at releasing energy compared to burning carbon directly, and most forms are readily available near anyone anywhere, be it charcoal, wood, coal, gas, or oil there is no sense in centralizing the use of carbon based heat release technologies to drive kinetic force to again convert it back to heat, because the heat sources are cheaper to just deliver to my house instead, and don't get me started on the bullshit of using heat pumps for indoor environment control with the ridiculous nonsense that causes, eg damp winter microclimates outdoors and dessicated skin indoors (in bulgaria, where reverse cycle AC is the norm for winter heating every office has ultrasonic humidifiers!) if it has to be electric, then at least use carbon resistance to make IR and point the emitters towards the humans, but it's bullshit better, close the windows, insulate the walls, add mass that actually stores heat, cook with gas, gas is the best, outstanding quality cooking heat, and don't build buildings with north facing windows for fucks sake

Might be that induction devices are crappy and clunky because of the manufacturers standard fiat mindset of cost reduction. Regardin clunky, to bring it back to ecash, with all its drawbacks, it could be a very smooth payment method. Where lots of internet payment methods bring a lot of clunkiness, like the elaborate but unsafe credit card authorisation or all the blockchain or node-related mess of other cryptopayments.

yes but if the mint knows who issues and who spends it's not private, stop saying it's private, it's not private that would require some more complex coding of denominations and mixing processes, and it's no big deal but i knew there was something missing from the story

For starters super just yesterday confirmed an implementation wasn't even doing basic mitigation for key tweaking (tainting mints to correlate to user metadata) Even with that mitigated, your still trusting a server not to use its upper hand to deanonymize you... Better to just use a database you trust directly without the bullshit, can always use ephemeral keys for access We do this using nostr notes only in lightning.pub
