Amethyst works great connected to .
onion relays.
You can also easily run one of those and maybe a bouncer like bostr2 to broadcast to many others.
Privacy goes up, mobile data usage goes down.

No, Amethyst relies on the Tor proxy provided by Orbot. Routes throigh Tor allor nothing. I find websockets working over Tor surprisingly well. Once the connections are established with a few seconds delay the speed is acceptable. Amethyst is well usable over Tor of needed.

Alby Hub is not yet on the Raspiblitz, just doing the basic research: https://github.com/raspiblitz/raspiblitz/issues/4727.
Going through the docs it seems the best self-hosted option is to deploy on a VPS with a public IP address readily available: https://github.com/getAlby/hub/tree/master/scripts/linux-x86_64
The other option is using an instance of LNbits with the upcoming NWCprovider extension: https://github.com/riccardobl/nwcprovider
Soon to be in a new LNbits release: https://github.com/lnbits/nostrrelay/issues/13. There can also use phoenixd and Blink @npub13lj…cfhw as well as the funding source.

Tried this way, but cannot make the Tor relays to connect.
Will likely need changes in the backend or a self-hosted Nostrudel with Tor access.

Fixed it seems by adding the bostr2 instance to General relays also:
#nevent1q…hlua
This amd the quoted post was broadcasted over Tor only from Amethyst to a bostr2 and a strfry instance.

2024-09-05 08:35:15

- reply

Are you using torsocks to run bostr2?
I figured if the bouncer is not torified the outgoing websocket connections are leaking the public IP of the server to the connected relays. (The client is safe.)

To broadcast a raw transaction over Tor anonymously
you have the command 'torthistx' available in all of your #Raspiblitz terminals.
To use it simply copy a raw transaction from Sparrow Wallet for example and paste it to the terminal after:
torthistx
It will return the TXID.

Truely FOSS Satochip javacards https://github.com/Toporin/SatochipApplet initialized with an airgapped, stateless @npub17ty…3mgl .
The cards act as a hardware wallet without a display, but with a PIN protected secure element. Mess up the PIN 10 times and the card is bricked. Blanks cost ~2 dollars with chip, ~5 dollars with NFC support. Can compare with #TapSigner, #BitKey and alike.
Find the modded images supporting the smartcard readers here: https://github.com/3rdIteration/seedsigner/releases

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:
- https://lightsats.com - top up in the browser and create vouchers
- hope to have this streamlined in the Blink Wallet - the PoC could be extended here https://github.com/GaloyMoney/galoy-voucher
- 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 https://github.com/cashubtc/nutshell
Custodial solutions:
- download eNuts https://www.enuts.cash/ or Minibits https://www.minibits.cash/ and use the default (or some other) mint
- looking forward to the fedimint instances in the wild
Does anyone has any other practical solution working now for async payments?
I'd like to pay bitcoiners more often, but sometimes not when I can just ask for a lightning invoice.

If you make multiple LN withdrawals to Muun it will create many UTXOs in your wallet which will be hugely expensive to consolidate.

Got my first Raspberry Pi 5
Running an auto-built #Raspiblitz test image on it already, seems really fast.
Swapped the SDcard and the SSD from an RPi4 node. There are no obvious compatibility issues (as expected).
If want to test can try the latest image built from the dev branch: https://github.com/raspiblitz/raspiblitz/tree/dev/ci#ready-made-images-for-arm64-rpi
(most important hint that it needs to be based on the latest RaspberryOS built on Debian12 - the Raspiblitz v1.10 image doesn't work on the RPi5, but the next stable release will!)

a very useful correction here: https://nitter.net/mononautical/status/1725813952377127375
bitcoind does rely on the mempool for fee estimation.
the estimatesmartfee algorithm works by tracking how long transactions in different "fee buckets" wait in the mempool before getting confirmed.
which means it needs to see a representative sample in the mempool.

2023-11-18 09:10:40

Thinking this through once again: #ordisrespector does not seem dangerous knowing that:
- bitcoind does not consider the mempool for fee estimation (only the past blocks).
- LN implementations and Electrum servers rely on the data from bitcoind.
Please correct me if I am wrong.

Using https://liquid.boltz.exchange you can balance your channels with a swap to LBTC for 1000ppm
or pay LN invoices up to 5million sats from your Liquid stash.
With Confidential Transactions (even cross-asset) batching achieves the same as coinjoins, glad to see the usage come.
To reliably break the transaction graph would need some peers to batch with maybe like in the JoinMarket Maker-Taker model.
With the amounts hidden the coinjoin soduko becomes impossible and the Taker inputs can not be identified even when there are only a few participants.

2023-04-22 13:44:57

- reply

Lightning is layer two as can be settled onchain directly.
Custodial ledgers and ecash mints are equivalent in the sense that there is no direct (meaning trustles) settlement to chain or LN.
They can be viewed as an alternative closed system or maybe as layer 3 (for the trusted conversion) depending on the definition.
By this view a mint or custodial LN wallet supports the base layer or LN only on the level of the custodian. The users transact intraledger and can swap out in a trusted fashion.

2023-04-21 18:21:53

- reply

That's good, but yes, the last hop pretty much still gives the node away.
Also needs to have LNaddress and zaps plugged in which is not that straightforward when it is only on cli.
There could an solution which generates the virtual hop through the LND/CLN GRPC or REST, but that is very implementation specific.
#[2] works for any BOLT11 invoice, more private and has a pretty simple API to work with.

Nice bot, thank you for building!
And now just look at the No Prio Fee:

I like to pay only the minimum fee so find it important to see the floor. To be clear I am most worried about the automatic fee calculation for the commitment transactions on the connected lightning nodes.

Please don't take me as speaking for what happens with the Raspiblitz project. I am an open-source contributor in my free-time and simply deciding what to work on by it being useful for me or not.
There have been no PRs offering patches for Core (which would still need to be reviewed and tested).
The dependence on any of these projects is concerning in itself and I think if someone not able to build Bitcoin Core from source is likely not aware of the implications either.
BTW the Raspiblitz - close to bare metal - way makes the easiest to make such modifications yourself, but as discussed above to have the supermajority of the node network run some patch is not that straightforward and in my opinion not easier than coming up with a new data structure for data storage.

With that I agree, you can choose what you want to censor from your own mempool.
It ranges from denying arbirary scripts to running mempoolfullrbf=1.
For me my node's mempool is the more useful the more accurately it is able to predict the next blocks.

It's my incentive to have an accurate fee estimation in my own node so the transactions broadcasted automatically won't underpay.

Ligess is a self-sovereign Lightning Address and Zap (NIP-57) server: https://github.com/Dolu89/ligess/

* an always on lightning node (eg. a Raspiblitz)

Know about nost.directory to add the twitter contacts, but woul like something I can keep locally.

Find here a guide to host an LNURLpay code over Tor with you own BTCPayServer:

Help on the lightning wallet front is much needed. Ask all your favorites to add support or help them if possible (FOSS wins).

Using the #Raspiblitz dev branch (can sync to it from menu - UPDATE - PATCH) the #lnproxy api and gui is available as a server.
Exposed via SSL and Tor.
Can also subscribe to a custom #IP2Tor to get a clearnet endpoint.
Testers are very welcome before the next major release.

Try to set in the lnd.conf:
debuglevel=debug
db.bolt.auto-compact=true
restart and monitor the logs for the compaction or any error until comes back up. Lower it the debuglevel to info afterwards.
If you use watchtowers check if they are connectable, the Info forbthe offline ones queeing up can also cause high memory usage.
