Long before Bitcoin could fulfill its promise as true peer-to-peer money, California quietly operated one of the largest unbanked, trust-based economies in the world.

For decades, the underground cannabis trade — especially in the Emerald Triangle — moved entirely outside banks and state control. Each fall, a quiet migration began: trimmers arriving from across the U.S., Europe, Australia, South America. Some landed on remote mountain farms, others found work in the back rooms of city warehouses. Introductions were everything — no résumés, no applications, just who vouches for you?

It was cash-only, always. Growers paid in stacks of $20 bills. Safes and duffel bags were standard business equipment. In the rural north, gas stations, restaurants, hardware stores, and feed shops all ran in sync with the cannabis cycle, though nothing appeared in official ledgers.

And the money didn’t stop at the county lines. In Oakland, San Francisco, and Los Angeles, it quietly kept entire creative ecosystems alive — funding music venues, art spaces, underground festivals, activist networks, and countless small businesses that could never have survived on credit-card economies alone.

It was a cultural crossroads: back-to-the-land hippies, permaculturists, traveling festival crews, artists, healers, and others living far outside mainstream systems. What bound them together was a shared value system — self-reliance, mutual trust, and resistance to gatekeepers. In both the cities and the mountains, cannabis money wasn’t just income… it was the cultural bloodstream.

In its strongest years, this was a decentralized, trust-based financial network — no banks, no central authority, no corporate oversight. It was cash as culture, not just cash as currency. Yet legalization has since corporatized much of the trade, pushed out many original participants, and disrupted the flow that sustained these communities. The transition is still fresh, and for many, uncomfortable. The vessel that carried those values has fractured — but the values themselves remain.

The structure of that economy — trust-based, peer-to-peer, and operating without gatekeepers — is strikingly similar to what Bitcoin, Nostr, and eCash aim to enable in the digital age.

If Bitcoin is ever to fulfill its everyday, peer-to-peer potential, it will need the same organic trust networks, cultural adoption, and shared values that this underground economy embodied. Bitcoin has the rails. What’s missing is the bridge: the human story that could connect communities who already know how to operate outside centralized systems, to tools that let them do it globally.

Bitcoin, Nostr, and eCash are not yet what this economy once was — but they could be, in certain ways. They carry the same potential for autonomous, borderless, trust-based exchange… only now without the geographic limits or legal risks of the old cash economy.

The history of California’s cannabis cash economy is more than nostalgia — it’s a living blueprint for how unmediated, peer-to-peer systems can sustain communities, culture, and creativity for many, even under prohibition.

For those of us in Bitcoin, Nostr, and eCash, this history is worth understanding. The values are aligned. This was a system that, for many, sustained communities and culture for decades without banks, without permission — and it built community wealth along the way.

It’s been on my mind for some time — how to bridge these worlds in a way that serves both. Maybe this is where that work begins.
