openoms - Nostr Hypermedia

GM. Happy Easter! Don't fall for April Fools today.

Heads up if using the testing / unstable version of Debian, Ubuntu, NixOS or other Linux OS based on these, there is malicious code in the latest xz package:

oss-security - backdoor in upstream xz/liblzma leading to ssh server compromise

>The malicious injection present in the xz versions 5.6.0 and 5.6.1 >Luckily xz 5.6.0 and 5.6.1 have not yet widely been integrated by linux distributions, and where they have, mostly in pre-release versions. Running stable versions are fine: ₿ xz --version xz (XZ Utils) 5.4.1 liblzma 5.4.1

Exercise: you got to send someone money, but the payee didn't publish a bitcoin or LN address you trust. The onchain fees are high anyway for the price of a dinner. Nostr solves this often, but let's say you just got some other social media contacts. Solutions: 1. LNURLw generate an LNURLwithdraw voucher and share the link or QRcode so the recepient can withdraw with most lightning wallets any time. This needs a LNURL server. Some ways to it: - run BTCPayServer - create a Pull Payment, share the link or QRcode - run LNbits - create a voucher with the LNURLw extension Custodial solutions: -

Lightsats⚡

- top up in the browser and create vouchers - hope to have this streamlined in the Blink Wallet - the PoC could be extended here

- there is of course the BTCPay / LNbits of someone else 2. Ecash Use ecash (that will be Cashu for now) - send the token as text and when the recipient downloaded an Cashu wallet will be able to convert the token to a lightning payment or trade it within the mint for free. - run LNbits with the Cashu extension, connect it to your eNuts or Minibits wallet - run a mint directly with

What a godsend this Nostr Client of LNbits extension is!

I have just configured it to connect to my usual relays and it acts as a multiplexer. With the client on my desktop or phone I just need to connect to this one relay which I can do even through a private wireguard tunnel (or using Tailscale). One connection to an anon VPS which keeps everything up to date and I am not broadcasting my IP address to all my relays any more every time I open a Nostr app.

To prevent painful consolidation costs the

DIYnodes.com – Bitcoin and Lightning nodes, parts and accessories

store is receiving sats only over lightning when invoicing a relatively small amount. If you have some L-BTC already it can be converted on-the-fly with the help of the built-in Sideshift plugin:

Pair this with the Blink plugin:

Use Blink as a lightning provider in BTCPay Server.

and your store can have virtually unlimited incoming ⚡️ capacity. Enjoy the power of the plugin system of @BtcpayServer and focus on the goods you sell. #FOSS @npub155m2k8ml8sqn8w4dhh689vdv0t2twa8dgvkpnzfggxf4wfughjsq2cdcvg @npub13ljnkd633c7maxatymv3y2fqq8vt3qk7j3tt0vytv90eztwgha9qmfcfhw

For anyone running BTCPayServer there is a new version (v1.0.6.0) of the Blink plugin available.

Installing it on your instance allows users to receive funds on Lightning to their Blink Wallet without the BTCPayServer instance taking custody. Use a Read-Write API key on your own server to issue bolt cards via the BTCPay Web Interface using a $15 device like: https://www.aliexpress.com/item/1005006458826905.html

This makes it possible to provide a fully functional end-to-end payment system using Free Open Source Software across the whole stack. Bonus: if a merchant would prefer to keep their income at US dollar value to escape volatility or help their accounting they can just set their default account to Stablesats in their connected wallet.
