Some Day Peg

A two-way peg bridging BTC to other chains. It works similar to a perpetual one-way peg; however, instead of burning the BTC they are locked up until a particular time in 20 years. Until then, the community has to figure out how to do peg-outs with, e.g., some sort of OP_ZKP_VERIFY or Simplicity.

We simply pretend that OP_NOP10 is OP_ZKP_VERIFY and let users lock BTC in the following script:

<program_hash> OP_NOP10
 OP_CLTV OP_2DROP

Sats4Files: Decentralized File Hosting based on Lightning

Sats4Files is a protocol for decentralized file hosting. It allows users to request data from untrusted servers, and upon receiving the encrypted data, they can pay for the decryption key via Lightning. The exchange is atomic, ensuring that the user only receives the data if they pay for it, and the seller only gets paid if they deliver the data. The protocol is an efficient form of verifiable encryption, which is similar to verifiable secret sharing using Shamir's algorithm.

This scheme is simplified and does not fully solve the problem, as discussed in the Limitations section. This writeup intends to spark interest to solve the remaining issues beyond the fixes that we suggest.

Sats4Files Problem

The client wants to buy from the server the file corresponding to a particular file_id.

Here, we assume we have PTLCs on Lightning instead of HTLCs. That means we can buy a discrete logarithm over Li

How to upgrade through every version of macOS

I was inspired by this YouTube video to try to upgrade through every version of macOS, starting with System Software 1 all the way through macOS 12. I ran into some pitfalls, and decided to document my steps here for anyone else who wants to do this to follow. This guide is intended for running on an actual (Intel) Mac. You need a fairly powerful computer (probably not a MacBook Air), and at least 100GB of free hard drive

Setup

Emulators

To begin, you'll need a few emulators. To be specific, one for the m68k architecture, two for PowerPC, and one for x86_64. I recommend Mini vMac, SheepShaver, QEMU, and VirtualBox, respectively. For QEMU and VirtualBox, look to their respective documentations for instructions on installing them. For Mini vMac and SheepShaver, just download and put them in

SMS Backups

Sms Backups (for the paranoid) using Andorid's "SMS Backup and Restore"

Install "SMS Backup and Restore" to backup periodically
- Configure backups to a cloud provider like "Google Drive"
- Ideally backup phone clals as well
Wait until the Cloud Provider runs low on storage
- This should happen relatively quickly, since my SMS files take 300+ MB each (they include photo/videos)
Download the backup folder

Various Versions of macOS/OSX will fail on install for various reasons. You can fix them by disconnecting from your wifi or network or resetting your NVRAM. Booting from your USB stick, opening terminal and doing: date ########## where the # nubers are below. Format is: MMDDhhmmYY

10.16 - 0.5 Leopard   - date 0101010121 <- Currently not needed
10.15 - Catalina      - date 0101010120 <- Currently not needed
10.14 - Mojave        - date 0101010119 <- Currently not needed
10.13 - High Sierra   - date 0101010118

10.12 - Sierra - date 0101010117

How to set up a server running NYM for dummies

Introduction

This guide is written for people that have absolutely no or little experience with terminal and remote server configuration. Should work on all Debian based distros although this has been tested only with fresh Debian 10 Buster. It does not yet cover the actual node configuration yet. For that see the official Nym docs here https://nymtech.net/docs/run-nym-nodes/mixnodes/

If you are complete beginner and just installed Debian on your VPS then I suggest going through the bash crash course in the introduction section

If you are at least little experienced, then skip to section Nym installation.
