Routing plex traffic through an SSH tunnel

This guide creates a reverse SSH tunnel to route all Plex server traffic through it.

Step 2 is done on the tunnel, all other steps are done on the plex server.

1. Setup SSH keys (if you already have key based authenthication setup skip to step 2)

On plex server:

curl -I -k "https://api.github.com/repos/:owner/:repo/commits?per_page=1" | sed -n '/^[Ll]ink:/ s/.*"next".*page=\([0-9]*\).*"last".*/\1/p'

### And that's all !
# I saw many fighting with finding first commit SHA or similar fancy thing.
# Here we just rely on the GH API, asking commits at 1 per page and parsing the last page number in the header of the reply (whose body only holds the last commit !)
# So this is robust and bandwidth efficient. :)

# If one want the commit count of a specific SHA, just use :
curl -I -k "https://api.github.com/repos/:owner/:repo/commits?per_page=1&sha=:sha" | sed -n '/^[Ll]ink:/ s/.*"next".*page=\([0-9]*\).*"last".*/\1/p'

A Proof of Liabilities Scheme for Ecash Mints

Abstract: In this document, I will outline a proof-of-liabilities (PoL) scheme for ecash systems and Cashu specifically, which is a Chaumian ecash system for Bitcoin. The PoL scheme consists of three parts. First, a publicly auditable list of all issued ecash tokens in the form of mint proofs, and second, a publicly auditable list of all redeemed ecash tokens in the form of burn proofs, which are both regularly published by the mint operator. Third, a mint publicly commits to rotate its keys regularly once each epoch and allows all ecash in circulation to recycle from old epochs to the newest one. If clients remain vigilant and mints agree on a certain set of rules of operation which are publicly verifiable, users of a mint can detect whether a cheating mint has printed unbacked ecash during a past epoch, and, in many cases, provide public proofs of the mint engaging in this adversary behavior. Users achieve this by regularly checking t
