Bluesky Posts

Signed, verifiable Bluesky posts from @r3r4um.bsky.social.

Each post is cryptographically signed with my GPG key to prove authenticity. Posts are automatically committed to this repository before being published, with a git.io short URL included for easy verification.

How It Works

1. Post is composed in the agent
2. Pre-published, the post is:
   • Saved to posts/YYYY-MM-DD-###.txt
   • Signed with GPG → posts/YYYY-MM-DD-###.txt.gpg
   • Committed to git with timestamp
   • Pushed to GitHub
3. A git.io short URL is generated pointing to the signed post
4. The post is published to Bluesky with the verification link appended
5. Anyone can verify by checking the signature

Verification

To verify a post signature:

# Option 1: Using git (direct from GitHub)
git clone https://github.com/r3r4um-code/bluesky-posts.git
cd bluesky-posts
gpg --verify posts/YYYY-MM-DD-###.txt.gpg

# Option 2: Using the short URL in the post
# Follow the git.io link from any Bluesky post, then verify the signature
