Mr. L

We should also not give into the phrasing of "hosted" vs. "unhosted" wallets.
There are seed phrases.
There are signing devices.
Some are connected to the internet.
Some are not connected to the internet.

Twitter is fun lately because boomers entered the #Bitcoin land.

2024-01-10 13:21:57

Controlling #Bitcoin UTXOs directly will probably be out of reach for most in the future.
Assume the following
- no tech changes
- $1 = 1 sat
- low fees like today, 30 - 50 s/vB
If you're not a Satoshi Millionaire, would you even *want* to spend 1.000-10.000 sats for 1 TX?
(Assuming $ = today's purchasing power)

Elixir and the Erlang BEAM are still so underrated pieces of technologies.
Many of today's software challenges could be built on this platform in a simple, clean way.
I'm currently working on a side project as well (hope to be able to open source it soon). Not a big project, but the platform and ecosystem offer all the moving parts and with relatively little code, you'll have a robust system up and running in no time.
Still love to work with this language and ecosystem 🧡

Little project I‘m working on:
„Mempool Monitor“ 👀
Monitors current #Bitcoin fee rates, notifies you if configurable thresholds are crossed.
Nice for when you want to know when is a good time to manage your UTXOs.
Not yet live, but would be nice to get early feedback.
How does it work?
1. You’ll configure lower/upper threshold of sat/vB
2. You‘ll get messages:
- low fees: fee < lower threshold
- in range: lower < fee < upper
- high fees: fee > upper threshold
Current MVP would send you a #nostr DM.
Works and was easy to add.
However, Nostr clients won’t notify you reliably in time, it seems so far.
I‘m open for other potential notification channels.
One could also be a more technical one: calling a Webhook of your service.
This would open up future uses cases, like executing scripts on your side.
Let me know what you think.
I hope I‘ll be able to get an MVP version online in the coming week(s).
The basic setup and service already works (alpha, but the screenshot is not faked 😊).
UI is completely missing, though.

Do mobile push notifications when receiving DMs work reliably for you?
I'm currently using Primal or Damus client.
It does not seem to work for me all the time on Damus.
Don't think it is available on Primal yet?

Anyone figured out how Nunchuk is implementing their „Honey Badger“ plan (I.e the one with Inheritance Plan)?
Their docs only get me so far but doesn’t seem to answer all questions. #note1dhv…eth8

2023-12-17 08:43:44

- reply

I‘m curious about this too.
- the inheritance key: Nunchuk says it’s a 2-of-4 setup. But if the conditions for claiming the inheritance are met, isn’t it effectively a 1-of-4?
Because they also mention that „all funds“ can only be moved if 2 of your own keys are used (the platform key should only be able to co-sign to the configured amount).
So, I suspect that the inheritance key has also the sole signing rights if time-restricted conditions are met?
What am I missing here?
Can the inheritance setup be restored in e.g. Sparrow as well?
- platform key: where exactly does the primary key reside? It must be a software key. But is this key also synchronized to the cloud and available on the desktop app or does it reside only in the mobile app? And how do I know, it does not internally have the majority of/sole signing rights. Given that the co-signing amount is configurable and is denominated in $ and not sats, this is still a little confusing to me and I haven’t figured out how that could be implemented without custom logic on their servers (I.e. in a trustless way) and restored on e.g. Sparrow.

Fun fact: I took a closer look at #Bitcoin because of Taleb‘s Antifragile.
His work essentially gave me the initial push before I really fell into the rabbit hole.
It’s ironic knowing now that he he later turned his back on #Bitcoin, but I still value his work and books.
Skin in the Game is one concept that I also really think is needed and missing in a lot of areas in today’s world, especially in areas like politics.

I am using Phoenix as well. It is a good choice to get into self custody smoothly & quickly.
However, I have also learned that many people struggle with the concept of writing down a seed phrase.
For new comers (that don’t even use password managers), this concept is pretty alien.
Now, I mentioned password managers but not to tell them to store their seed phrases in password managers. That’s not a good thing to do.
I mentioned password managers to highlight the fact that most people are still pretty bad in managing their passwords even in 2023.
So, I kind of get why many resort to WoS because it is very easy to get into BTC.
People are used to having everything managed for them and it being able to recover somehow (I.e. customer support etc.).
IMHO, you‘ll scare these kind of people away (or lead them to failure and fuck up because they lost their seed phrase that was written down on paper).
For these people, I can see why WoS is a good start. Then from there, level up.

We‘ve been traveling in and exploring Norway 🇳🇴 for the last 2 weeks.
Beautiful country!
Nice cities.
Friendly and welcoming people.
3 things noticed right away:
- Language
- Infrastructure
- Money
Spoiler: Cash is gone and will not come back.
#Bitcoin can fix this.
Language:
Nearly everyone speaks English and fluently so.
Even in smaller towns and when meeting older folks.
(I only want to highlight this because this is certainly not the case in Austria 🇦🇹 where I come from.)
Communication is easy.
Infrastructure:
We only used public transport.
Oslo - Voss - Bergen - Trondheim - Oslo.
On that route, and within the cities, public transport was easy to use.
Important learning: if you want to hopp on a bus 🚌, you need to indicate this to the bus driver when the bus is approaching the bus stop🙋‍♂️
Otherwise, the bus will not stop and pick you up.
Didn’t expect that.
Learned this quickly, though 😅
They really want to go electric ⚡️
With everything!
Cars, bus, ships,…
And in bigger cities, the share of electric transportation is already pretty high.
And I must say, it is really nice!
Leaving aside why Norway is pushing so hard to go electric: From a pure „user experience“ point of view, we liked it!
Cities seem to be quieter and calmer.
From an outsider view, it also seems to work.
Note: I was only passenger and did not need to use the charging infrastructure myself. Happy to get feedback!
The transition phase also seems to work nicely.
But Norway has the resources and capacity to do so.
They did not kill their oil industry.
They used the revenues to build up the new infrastructure.
Money:
Cash is already gone in Norway.
Everything is digital.
There are sometimes even „cash fees“. So, it’s more expensive to use cash.
The next thing is weird to say as a #Bitcoin‘er:
From a pure user experience view, it is nice!
It’s seamless and nice when you can pay everything by just getting out your phone.
Especially as a foreigner.
But you also experience how old and expensive the current banking system can be.
First, I used my debit card I use at home. Works, but is expensive because they charge quite hefty fees for exchange rates (EUR -> NOK).
After a couple of swipes, I saw the fees and went: „ugh… that’s getting expensive“.
Revolut helped here.
Create a virtual card. Exchange EUR to NOK for free. Add the virtual card to Apple Pay and all the expensive fees are gone.
However, the #Bitcoin‘er in me didn’t really like it.
All the data is now captured by 2 services.
Apple, and Revolut.
But again, from a pure user experience, it was nice and easy to use!
#Bitcoin can fix this.
Same user experience.
Better privacy.
But then something clicked in me.
Cash is gone and will not come back!
We are going digital and it might not be a bad thing even if digital does not mean #Bitcoin right away.
People are getting used to paying digitally.
And this might help the adoption of #Bitcoin
When we speak of cash, we mean the printed paper.
But we are going digital and we will stay there.
In the current system, digital money is debt. It‘s not cash. And in the worst form, it might even be CBDCs. Yuk!
#Bitcoin is digital.
It also works more like cash again, but that’s not important for most people.
Most people don’t care about this distinction.
But the user experience in #Bitcoin is much like with the current banking apps.
It’s digital.
You walk up, order something, get out your phone and pay.
And I argue, societies that are already cashless (i.e. digital) may be primed for a quick #Bitcoin adoption once it starts picking up steam:
They are used to paying digitally.
However, why would I want to switch as a Norwegian?
It’s just one digital money for the other?
The incentives in rich, already digital societies are not there. At least for now.
They also experience inflation, though.
However, it’s not bad enough, yet.
And in countries like Austria, if you want to use #Bitcoin, taxes will be an additional burden.
Cash will go away.
But that might not be bad, since we have #Bitcoin now.
Money is and will be digital.
Societies that already use digital money, might be quick to adopt #Bitcoin.
But there needs to be a reason good enough to make the switch.

#Bitcoin for unstoppable money
#Cashu for unstoppable anonymous transactions
#nostr for unstoppable speech

2023-04-23 12:39:04

Cashu adds a high level of privacy to #Bitcoin.
But it also requires trust.
(Custodial LN does so too. So, nothing new.)
It works much like the initial, gold backed central bank and cash system.
Mint: you give gold/sats, receive paper/ecash
Melt: you give paper/ecash, receive gold/sats
Use: trade paper/ecash for goods and services
Trust:
- the bank/ecash mint to (1) return gold/sats for paper/ecash, (2) not expand the supply of paper/ecash
- yourself: if you lose the paper/ecash tokens, it's gone (much like cash, but I think Cashu is working on a backup-restore process)
Cashu mints could become the banks of the new world but with much better attributes:
- easy to spin up
- no accounts required (no KYC)
- ecash tokens can be tied to #Bitcoin
- WIP: better transparency. It's code. There are projects trying to solve the "trust requirements"
(I'm learning and thinking in the open.
Please correct me if I got anything wrong.)

Depends on what is the reference to compare it’s stability to, right?
E.g. Bitcoin is stable when looking at money supply (never more than 21 mio; 1 sat = 1 sat).
However, It is not stable when comparing it’s purchasing power to, say, USD or EUR at this point in time (and maybe never will be).
But generally, I know what you are meaning to say and would agree to that 👌

The first LN invoice represents the „balance“ (if compared to my thoughts) and you send ecash as long as you have any and then get new ecash tokens with the next LN invoice.

And you don’t even need to handle the „balance“ in the background as I would have needed to do in my thought exercise.

- reply

I thought about using LN for monetizing API access, but this sounds better and achieves the goal to reduce roundtrips (compared to „create invoice for every request“)!
If I understood Cashu correctly, you can „top up“ a balance with the first LN invoice (say, 1000 sats), and then send 10 requests using 10 sats worth of ecash?

In theory possible, but your client would need to allow to control which relay is for read-only/write-only.
And then you probably will run into a problem at some time 🤔
If you publish on Relay X only, but never read from it, I don’t think you’ll see your own content then again.
So far, relays don’t talk with each other. Clients are in charge to distribute data.

Would be a perfect stack for real time and web sockets 🚀
It offers great features for web sockets, but I fear that using e.g. Phoenix Channels would not work. I believe nostr clients would then need to use the Phoenix Socket JavaScript library to connect 🤔

Seems to be a perfect fit for Nostr. An Elixir relay, and a Phoenix LiveView Client.
But I need to learn more about the protocol first and look at some implementations in more detail.

Nostr seems to be the perfect opportunity to write a relay in Elixir and a client using Elixir + Phoenix LiveView 🤔
