And we're running Ubuntu 18.04 on the ROC-RK3566-PC from @TeeFirefly.

I was bamboozled by the fact Android was pre-installed on the eMMC and had boot preference.

Flashing the eMMC with Ubuntu was troublesome, I'm now running it from an SD card. I think.

Next steps: IBD. ImageImageImage
Pics or it didn't happen. Image
NVMe disk present now. Image

“I want you to understand what it means to lose your freedom.”
-- Ross Ulbricht, Bitcoin Conference Miami, 2021

Transcript:
Hello, this is Ross Ulbricht.

I'm calling you today from prison. From a maximum security federal penitentiary. We don't have much time together today and I don't know if I'll get another chance to talk to you like this.
I'll say as much as I can but when it's time to go I'll have to hang up and go back to my cell.

I have lost my freedom. That's what I want to talk to you about today.

Installing @getumbrel on an Odroid HC4.

A small guide 👇
Why the Odroid HC4? It's self-contained, it can boot from a SATA SSD, doesn't need any adapters, cables, SD cards, workarounds or other stuff.

It only uses a 1 TB Samsung 860 QVO SSD.

Total hardware cost is ~$150.
Why Umbrel? It's a slick interface, defaults all traffic over tor, has an app store so you can easily add f.e. BTCPay Server or Specter Desktop.

@jack is forcing my hand a little. I have a backburner project about the genesis block: hodl.camp/genesis_block/

It's an annotated version of the genesis block where you can click every piece and get an explanation for it.

But, I'm a coder, not a writer.

I need help. 👇
A fair number of items are missing content. You can see the amount of detail I would like to get into on some fields I've filled out, but I lack the knowledge and/or writing skills to succinctly write all of them down.
Also, it doesn't scale properly on mobile. As I said, I'm a developer, but mostly back end. CSS is not my strong point.

#Bitcoin

A thread on money: gold, fiat and bitcoin.

According to economic theory, the characteristics of money are:

• durability
• portability
• divisibility
• uniformity
• limited supply
• acceptability

👇
Gold has supreme durability, good uniformity, limited supply and reasonable acceptibility.

The problems with gold are divisibility and portability.
It is difficult to divide gold. You need specialised tools and certifications. Gold is very expensive for it's weight, so there are practical lower bounds on divisibility.

Testing the Odroid HC4. Running Ubuntu Minimal 20.04 and Bitcoin Core from a 1TB Samsung 860 QVO. No SD card needed, just jam in a SATA SSD into the toaster.

Next up: bitcoin info on the 1" OLED screen. ImageImageImage
Why is this exciting?

It makes a full node a little step easier. No more SD card, just push a SSD in the toaster case, maybe add a spinning disk for block storage. No cables needed. No USB quirks mode. (RPi4 👿)

Node status on the OLED screen.
It supports ARM v8 Crypto Extensions. This will have ~12% speed improvements for IBD. This will bring the IBD time down below 40 hours. More numbers will follow. Image

How would hyperbitcoinization look like from a market perspective? Two recent events happened which show a glimpse. If you combine them, an interesting picture emerges. A short thread: 👇
The first event: the conversion of company cash reserves into #bitcoin. There are currently two known companies which did so and announce it publicly. These reserves are relatively small, and those orders could probably fairly easily be filled OTC.
The second event: @CashApp was sold out on #bitcoin. More and more bitcoin onramps, or maybe better, fiat offramps are available. They have to source a steady stream of supply.
