Civic & protest infrastructure
Flyers, stickers, and signs become a live coordination surface - scan for the current trusted instruction, not a stale redirect.
Research, not shipping yet.
Why live flyers
Protests and mutual-aid actions move faster than paper. Meeting points, routes, legal numbers, and safety copy change - old flyers keep circulating anyway.
- Trust and timing Bad info wastes time, splits groups, or puts people in danger
- Same ink, new truth Organizers update network status without reprinting everything
Example · march flyer
Plans change
- Meet Greene Square instead
- City Hall route inactive
- Medical: 3rd Ave · updated 14m ago
Compromised
- Revoked - do not follow
- Use official organizer channel
What every scan shows first
- campaign status
- current instructions
- last updated
- organizer verified
- safety notice
- meeting point · route
- legal aid · jail support
- medical / water station
- revoked or active
No blind redirect. The flyer stays the same - the public instruction changes.
Secured with keys
Civic objects are high-risk - counter-protesters, infiltrators, and copied flyers are real.
Updates and revokes are signed with an organizer key that never leaves trusted devices. The network only accepts changes with a valid signature - scanning a photocopied QR cannot let a stranger rewrite instructions.
- Revoke in one signed action Compromised or duplicated flyer → immediate “revoked” on next scan
- Not the same as crowd vouching Campaign flyers should trust organizer keys, not open social vouch - so someone cannot “act like a supporter,” collect trust, then flip instructions
- Separate keys for separate roles March campaign key ≠ personal card · recovery backup · short-lived operator keys that can be rotated after an action
Social trust still matters for people - but public instructions should be cryptographically controlled, revocable, and visibly timestamped.
Resilient coordination
Usually
- Feeds, screenshots, rumor chains
- Stale PDFs and dead links
- No way to kill bad copies
Live flyer
- Scan what is in front of you
- Signed updates · visible revoke
- Is this still trusted?
Printed material becomes live, revocable coordination infrastructure. That is the magic.
