I am also quietly extending nostr wallet connect to become the backend superpower for #nostr #safebox.
First up and working is "offer_record" and "present_record" so that any two #safebox instances can directly share record.
I have also built the ability to issue to someone's NFC - so if they don't have their phone or app, they can still receive the record.
I will also be adding the directives from remote signer, so I will be able to sign something with my NFC card. The use case for this is a physician issuing a signed record from a medical #safebox that they control, but adding their personal attestation to make the signed record actually valid in the eyes of a governing body.
Onward!

An update to #nostr #safebox main screen. You can now select the currency of your choice. All payment amounts default to that currency. Of course, you can still choose sats.
Why fiat? Because the majority of the world is just looking for a better payment rail. That's it. No compromises underneath, just presenting what users want.

Easy solution to lessen the burden on society: send the retirees to the front…
Aging Warriors Step Up for Ukraine’s Future
The Wall Street Journal
Jun 28, 2025
The call sign “Did ” or “Grandpa” is so common in Ukraine’s army that two artillerymen in a four-man howitzer team on the eastern front use it. “I may be of age, but I like to keep moving—sitting at home or in a headquarters isn’t for me,” one of the two, Andriy Kukhar, said on a recent day hunched down in a small dugout near Chasiv Yar, in the country’s east.
Now 46 years old, he listens to the radio, awaiting his next instructions as he keeps an eye on his phone for news about his granddaughter.
The other Did is his 53-yearold comrade Mykola Voskres, who has five grandchildren, most of whom now live abroad. He left his job working construction in Poland and signed up as a volunteer the day Russia launched its fullscale invasion in February 2022. He thinks the sacrifice is worth it. “The younger generation of Ukrainians should focus on building their lives and preparing to rebuild the country after the war,” he said.
The ubiquity of the nickname points to a growing problem Ukraine faces as its war for survival continues into its fourth year: It needs all the fighters it can get.
U.S. officials have pressed Ukraine to lower the age of mandatory service, but Kyiv has resisted, worried that a wholesale slaughter could badly damage the country’s demographics and its ability to rebuild after the war. It has reason to be concerned. The economic turmoil of the 1990s, following the collapse of the Soviet Union, triggered a sharp drop in birthrates. According to the State Statistics Service of Ukraine, there are significantly more men over 40 than there are in the 18-25 bracket.
All men between the ages of 25 and 60 can be drafted to serve in Ukraine’s 880,000strong defense forces. Ukrainian soldiers say the units’ most common age group is 40 to 45. Many serve as drivers and tank operators after having served in other roles.
Ukraine still has an untapped reserve of potential soldiers—young men between the ages of 18 and 24, physically fit and often skilled in the techniques that could enable them to become effective fighters in a theater dominated by drones and other features of modern warfare.
The government launched a new program hoping to entice young recruits with a $24,000 sign-on bonus and access to an interest-free mortgage. But so far men under 25 remain exempt from compulsory military service.

See that white dot? That’s a NFC device that has been provisioned to accept and send payments on behalf of the #nostr #safebox wallet on the left.
The vision I have is that you can carry this white dot at all times and access a payment network where you can send and accept payments out in the real world independently of your phone. If you look closely, you see the payments sent and received via the “white dot”.
I am also experimenting with the sharing of emergency information. If the white dot is read, it could present your emergency information to a first responder. Still working through the security and use case considerations, but it can be done!

2025-06-04 11:27:33 UTC

This payment scheme approach has been long established. It used to be called ‘tokenized payment scheme’, until the word ‘tokenized’ became stupid.
The most important part of the scheme is that the payer can be ‘offline’ - so long as the acquirer can get the data, they can fire it off to the right ‘vault’ to get approval. Mastercard and Visa have their own vaults to approve transactions, then they tally them up and send them the issuing banks for final settlement.
So I’m replicating the same thing here. In this case, the payment card is something you issue to yourself, which you can use for an offline payment.
So if your phone dies, or you have no connectivity, you can whip out this card from your rfid/nfc protected wallet and still make a payment!
Of course, this is still early days, and all of the security and trust needs to be thoroughly tested. You wouldn’t link your life savings to this. But the idea of having a card, instead of your phone, that you can stash away that pays from your Lightning wallet is pretty compelling!

Well, holy shit I got nfc payment working end to end with Nostr Wallet Connect!
The #nostr #safebox issues a payment card - an encrypted payment token that is written to a nfc card.
When that card is read by another wallet, it generates the lighting invoice, extracts the vault url, the encrypted token and sends the details to the vault
The vault decrypts the token, figures about what nwc wallet to send the invoice to via nwc.
The nwc receives the payment instructions, decrypts it containing the invoice and pays it.
Voila! It all works! That means I can issue my own nwc payment card and use it like a debit card on another #safebox that accepts nfc payments.
This replicates how the payment card networks and how banks provision a card you can carry and add to your digital wallet. With no banks!

Payment by NFC with #nostr #safebox
I have the secure plumbing figured out. Still more to implement but here is the gist:
1. Reader acquires encrypted token from card and amount
2. Generates lightning invoice.
3. Acquited sends encrypted token and invoice to token vault endpoint
4. Vault decrypts token and issues nwc command to pay invoice
5. Wallet pays invoice
6. Poll invoice and notify user invoice is paid.

In addition to coding, I spend a lot of time reading far-out stuff, and then try to dial back what I’ve learned into something pragmatic that I can apply. For example, I am reading a PhD thesis on conscious machines, and have concluded we are nowhere near building anything conscious. A housefly has more consciousness than the most sophisticated LLMs out there. So let’s not worry about conscious AGI machines quite yet...
But what I have learned is that our own consciousness is being actively hijacked, so that the imperative for me is build capabilities that resist this highjacking. That means building components that I can delegate control without fear of the component controlling me.

That’s the challenge I have. With what I’ve learned from #nostr , I honestly don’t know how I would conduct myself at these types of conferences. I’ve concluded that one of the key protocols #OAuth2 as a base protocol is the core problem, but the industry is too far along that path for any useful debate.

This is what is being presented (today) as ‘state of the art’ at the identity conferences.
From what I have learned what I can do with #nostr, this is unnecessarily complicated because they are not using a cryptographic protocol at its core (like nostr).
Plus there are some very problematic components, namely, the ‘Orchestration’ and ‘Authorization’ components.
You can wipe this complicated architecture cleanly away with signed events with kinds and relays.

The most exciting thing I see with #nostr is to build ‘digital selfhood’ capabilities that exist on the network, independently of any app, device, or platform accessible only by you.
With your trusted client of choice (for example,Signal) you just add the capabilities you need in that application context. In the example below, you add payments, sharing and storage to Signal (if you wish).
This is the type of new architecture I am seeing emerge with my efforts on #nostr #safebox. - I am building digital selfhood capabilities, not apps.

Maybe one day, it will be as simple as this.
