Repost because I'm so proud. Forbes article about Bitchat x Cashu:
"The Bitchat-plus-ecash model widens bitcoinβs surface area without tampering with its monetary policy, showing that hard money can be used in contexts where payment speed is important and internet connectivity may or may not be available."

Beautiful π
Bitchat + Cashu = Cuba freebom
Ace. Gotta dig in more. Want to do a workshop with our meetup soon.
Where my bitchat? π I think this is a MASSIVE WIN for freedom. Thank god for the devs
*freedom

I get hung up on the technical inaccuracies, but publicity like this is a big win π€
Future in making ... π¬ π π₯
πππ
A huge win for a freer internet π€π₯
Very cool! Congrats!
I'm not clear on how ecash would work without an internet connection to have the mint sign the transactions / prevent double spend π€
I'm so new to this though
π
This is a phenomenal achievement, Calle! π₯
Valid reason to be mega proud π§‘
Congrats π₯³
Hella article!
Once Cashu can be used over Bluetooth or mesh networking then it's tiempo de libertad!
proud dad moment
im proud of you, and im a dad
Is it true that the cashu protocol prohibits creating more ecash than bitcoin that is deposited? So by design it inherits a fixed amount of ecash that can be created if you're using cashu?
No, there's no way to prevent that. I found the article to be imprecise in that point, esp because it later contradicts that point when it says you need to trust the issue to not debase the ecash. Maybe I didn't get it right.
That world is already built .. we are waiting for other to join in ..
you have the right idea. sending ecash tokens offline does not prevent double spending. it's just as unsafe as getting a bad paper check.
any time it looks like there is a hole in ecash where you are not safe or something bad could happen to you, just assume that hole is real. ecash is basically an overhyped toy that requires too much trust.
well done! π and perfect timing for the emergence of bitchat*. I think minimally it has at least given some people hope knowing there are people, developers, organizations, and protocols that offer alternatives to the mainstream, compromised, and centralized corporations' apps that they are used to with data leaks, identity theft, backdoor access to private messages, files, and so on. Privacy will remain a basic human right.
I like the anonymity/ privacy aspect of it. There's a lot of value in that, although you do have to trust the mint. But after hearing so much talk about it I thought someone had come up with a digital, offline bearer instrument. my hopes were too high
What I don't understand with Bitchat is that as long as the app is not constantly opened it can't be used as a node to route the datas right ?
So even if many people were actually using it around it would not work ?

Nice work!! How to we get to a trustless Cashu mint? How can I start a mint, that even I canβt rug? Multisig? Thanks!!!

Amen.
Go team!
Also pretty well written while talking about complex subjects !
Truly awesome.
How are you able to send ecash on bitchat? I havenβt done that yet
I might have to adventure into the city to try #Bitchat. Just me and the goats out here in the countryside.


Haha I got to try it with my cousin whom I havenβt seen in over 20 years. Works great. We should try it together when we hang!
For sure!
funny conudrum on this one... bitcoiners buying land and migrating to the countryside, and freedom tech nudging them back to the cities... lol
Hard to kill a city. βScaleβ by Geoffrey West is a good read.
Same same in Bournemouth. Nada!
Ditto! Sans goats.
Hahaaa love that
Bournemouth? Iβm originally from Southampton!
Fact. Itβs BTC that has enabled me (us) to get land and live away from the masses. Oh the irony!
Nice!
Are you me
Not sure, am I Β―\_(γ)_/Β―
Thnx for the recommendation! The network effect is awesomely powerful... will check it out.
Very cool. How so? Are you paying your bills in btc?
π€πΌ
Nothing quite that daily/transactional - although I am working on it. It's given us the bucket of funds more quickly than fiat mining ever could. We just got lucky, early.
Amazing. You gotta tell me more when we hang eventually
Wow. Small world π Stateside now I'm guessing? Greetings from the South coast β‘ππ€π§‘
Yeah been in the states for over 20 years now. Rest of my family are in Southampton and Gloucester. Havenβt been back in a few years, need to make the trip again soon.
Well make sure you drop into to our BTC meetup on your next visit and say hello. I'll be glad to buy you a pintπ§‘π
Unfortunately I'm sure you won't find anyone in the city either
