## Money

Free and open-source by design; sustained through Peaceful Foundation’s pooled infra budget and optional philanthropy or institutional support.

Costs remain trivial and relative at any adoption level; the Passport exists to secure trust, not generate profit.”

## Assumptions

	each user → 2 logins/month, 1 profile edit/month (averaged), 30 profile views/month
	profile JSON size → ~5 KB
	Workers paid tier → $5 covers 10M requests, then $0.30 per extra million
	R2 → free 10 GB, then $0.015/GB-month
		Class-A writes → $4.50 per extra million
		Class-B reads → $0.09 per extra million

## Costs at Scale

the system is statically hosted on Cloudflare, with Workers handling writes and R2 storing profile JSONs — meaning it inherits the same cost model as Calm.College and Hexagons.World. This reinforces that the system scales linearly and cheaply (≈ $0 at pilot, <$10 at 1 M users)

### 10k Users
		storage → ~50 MB (free)
		reads → 0.3M/month (free)
		writes → 10k/month (free)
		Workers → ~30k/month (free)
		≈ $0 / month

### 100k Users
		storage → ~0.5 GB (free)
		reads → 3M/month (free)
		writes → 100k/month (free)
		Workers → ~300k/month (free)
		≈ $0 / month

### 1M Users
		storage → ~5 GB (free)
		reads → 30M/month → 20M over free → ~$1.80
		writes → 1M/month (free)
		Workers → ~3M/month (covered by $5 plan)
		≈ $6–7 / month

### 10M Users
		storage → ~50 GB → ~$0.75
		reads → 300M/month → ~$26
		writes → 10M/month → ~$41
		Workers → ~30M/month → ~$6
		≈ $75 / month

### 100M Users
		≈ $810 / month

### 500M Users
		≈ $4,080 / month

### 1B Users
		≈ $8,200 / month

### 8B Users (world Scale)
		≈ $65,300 / month

## Takeaway

	10k–100k users → effectively free
	1M users → under $10 / month
	10M users → tens of dollars
	100M users → still under $1k / month
	1B+ → low five figures / month
	worldwide (8 billion) → ~$65k / month infra
