ASIC Manager

Installation

Create virtualenv and install python dependencies:

python -m venv envs/asic_manager-env
pip install -r requirements.txt

I'm using python3.11 but any recent-ish python3 should be fine.

SeedSigner "firmware" isn't what you think it is

On Rabbit Hole Recap #320, ODELL said:

"If you are using a SeedSigner in single sig you have to make sure that that device never leaves your sight. If someone gets access to it, they can put malicious firmware on it. [...] And this idea that you're going to share it among communities in single sig is batshit crazy. That is not a good trust model."

This was a few weeks back. Things have gotten spicier since.

My goal here is to LOWER the temperature.

SeedSigner v0.8.0 Release Notes

Quick Highlights:

Addtional legacy signing support:

P2PKH (bip44): Legacy format dating back to 2014.
P2SH multisig (bip45): Legacy multisig (also 2014).

Run Proxmox Backup Server (PBS) on a Proxmox VE host

Rather than set up even more infrastructure, I run Proxmox Backup Server on the same machine that's running a Proxmox VE host.

Install Proxmox Backup Server

Open a shell on your Proxmox VE host. We'll be installing PBS alongside Proxmox VE at the OS level. We will NOT run PBS inside a container.

Create new CT

General

CT ID: I keep these sequential and mappable to their LAN ip (e.g.: CT ID 201 -> 19.2.168.1.201)
Hostname: what Proxmox will call it (e.g. "bitcoind")
Password: VM's root password

Template

Use the standard Debian 12 template. If you haven't already downloaded it:

Create a Bitcoin Core Node CT in Proxmox

Create the CT:

Debian 12 image
4GB system disk in local-lvm
6GB RAM, 0 swap

Add a data disk mount point

In the CT's "Resources" > "Add" > "Mount point":

Storage: "Directory" disk from above

Basic Debian 12 CT instances

Guides to creating specific instances as CTs:

	def secp256k1_example():
	"""Usage example for secp256k1 usermodule"""

	# randomize context from time to time
	# - it helps against sidechannel attacks

	display resolutions.
