One amazing thing I learned about (out of many) at the ecash conference
A router for sharing internet
Someone from India, living in a place with a lot of internet access problems, built a set-up where people can buy internet without having any internet in the first place. 1 sat per minute
He built a captive portal that you log into and the page says — I take ecash from this one mint, get ecash from there and paste it into this text box — you paste it in, hit enter, and you’re online
You’ve made an offline payment and voila, you're now online
There are many exciting Bitcoin developments happening but it's becoming more clear that ecash is a wholly different, complementary technology that does different things, including many things that Bitcoin can't do no matter how many upgrades it gets

He is the one who told me about it :)
There's still a chicken-egg problem of getting something from that mint. But either someone might already have ecash from a previous time they were online, or maybe we'll have 7-Eleven ecash one day? Perfect use case for physical scratch cards.
Amen brother! 🙌🙏
Ecash is online not offline.
Sender does not need to be online, receiver does to prevent double spending
I literally saw a demo yesterday for putting ecash on a hotel-type card
Have to inform myself on this! What would ecash be and why is it different from BTC… you don’t have to answer, I will take this to the study room 🧡
That’s awesome! I knew we didn’t need helium or other shitcoins - just straightforward Bitcoin tech doing its thing. It’s just all about layers.
I know that I don't know as much as everyone else, but I do know this. I sell products on @Shopstr Markets and @calvadev⚡️ has been extremely helpful. They use @calle 👁️⚡👁️ for the transactions, and I've never had problems with it. Ppl order, I get the Sats, I get the address and what they order, I ship. They are happy, and I did my job. V4V. The Bitcoin Standard.
Hey Alex, I’ve been tryna find that hoodie in your pfp, mind pointing me in the direction where I can grab one ? Thx
Correct
I actually custom made it! :)
Was able to get one of the routers up and running during @btcplusplus, and after some initial troubleshooting, it worked great! It's pretty magical seeing it in action.
You can set one up with the following repo:
H/t to @DM for new npub for his work on the project; forwarding any zaps on this note to him.
If you're in Berlin, you can also purchase a router to run the TollGate software directly from him via @Shopstr Markets:

Need to keep learning about ecash
Thanks for sharing
Yes exactly, now you need to pay for WiFi at 7-Eleven if your not a customer with encumbered e-cash on an invoice.
Massive
Ecash is like a poker chip representing bitcoin. Give Bitcoin to the mint (casino), get chips back, spend however you want (the mint doesn’t know how you use it, private by default). Cash out whenever. Only risk is trusting the mint not to steal your Bitcoin or printing more tokens than they actually have
By whom? And where can I learn more about it?
If the router can support eSIM, for example, which we buy at Bitrefill, it seems like we can get a local ISP connection without having to do KYC, right?
Actually I am annoyed at the ISP via GSM in my country which is expensive and has a small quota.
I hope to use Starlink but the monthly rate is still expensive, try cheaper even though the speed is limited to 20Mbps

Thats really cool. This is exactly the kind of scenario where the custodial and trusted nature of an ecash mint just don’t matter. Great use of the tech!
@calle demonstrated it to me, was amazing, but was coded by someone else in just the last few days, he can tell you
Game changer.......

🤯 

Everyday I learn something new on #nostr that X just can’t compete with. This open source development is changing the world. Nice work
this is some life changing shit...

Sounds like Boingo with Bitcoin.
It turns out that once you have a cheap, fast, and programmable payment layer a lot of innovations become possible.
Too bad a lot is basically in a legal grey area.
*Tips hat.
Love it. That explains why I haven’t been able to find one ! Thanks anyway
Wieviel kostet das pro Stunde?
Next we need LoRa-based routers that do this so we can accept users from further away than simple 2.4G hz distances.
Yes, LoRa is bandwidth-limited, but they are very cheap. Couldn't these devices be stacked, so you'd connect to a thousand of them instead of just 1?
Lora based mesh network
Maybe ecash enthusiasts need to learn what bitcoin can do even without upgrades:

Cashu isn't an upgrade to or replacement of lightning. Mints are lighting nodes. The scenario calle described literally is not possible with LN alone.
- Please read the tweet I replied to so that you understand the context of 'upgrades'
- Mints are third parties who custody bitcoin for users that may or may not use LN nodes. I have experimented enough and running a mint: https://thismoneydoesnotexist.lol
- It is possible with LN
Great. Then we will have both solutions
LoRa (and nostr) can be really useful for metadata that routers use to discover new peers. When it comes to transport, I've accepted that TCP-IP is the best we've got. However, I don't accept authorities like ICANN and IANA as a requirement. I think nostr relays allow us to have efficient transport on competing networks.
We still need alternatives to TCP/IP
Has anyone tried putting the TCP UNDER the IP?
LNURLw works if you're offline, but your internet gateway is online to redeem the payment. You can also use e-cash non custodially if you run your own mint
Custody clearly comes with risks, though I want to have e-cash if I must use a custodian, because standardizing the interaction with custodians allows me to leave the custodian frictionlessly and it happens to come with privacy.
Yesterday I witnessed atomic real time channel rebalancing involving mints. Users of lightning can benefit from the liquidity without using custodians themselves.
> You can also use e-cash non custodially if you run your own mint
Running your own mint, using it to mint ecash for yourself does not improve privacy. You might as well run LN node instead and use LN with self custody.
Recipient needs to be online for redeeming e-cash if its issues by untrusted mint.
> though I want to have e-cash if I must use a custodian
Why do you need a custodian in the first place? Whole point of creating bitcoin was to create e-cash with no trusted third parties. You can read old discussions on mailing lists, whitepaper and initial website.
> Users of lightning can benefit from the liquidity without using custodians themselves
AFAIK e-cash is used for small amount. Lightning already gets enough liquidity from boltz swaps, centralized exchanges etc. Ark and Mercury could provide more liquidity in the future without involving trusted third parties.
- it's not a tweet
- cool
- no it's not
Yes I was responding to someone on twitter at the same time so wrote "tweet" instead of post. It is possible and shared multiple times in this thread DYOR.
Can I tip the homeless guy panhandling outside the 7-Eleven in ecash someday?
Dude I still can’t find anywhere reliable to make this exact hoodie LoL
Would u mind posting the site ?
### An index of #TollGateIndex related events on nostr
Yet another incomplete list. Feel free to publish an improved or updated #TollGateIndex if you are aware of #TollGate related events that belong on the list.
