A bill is worth what your neighbors will trade for it.
CurrentSea X-Change, or X-Cents, is a way for a community to reassign value to the coins and paper money it already holds. No new mint, no permission slip, just an agreement and a few stickers.
Try it on the right: wrap a $20 bill in plastic, then spend it around town.
Money already runs on agreement.
From Yap Island’s stone discs to modern fiat, money works because people accept it. X-Cents starts from that fact and draws a practical conclusion: if acceptance is what gives money its worth, a community can decide what its own coins and bills are worth to each other, especially where official values have left people short of what they need.
Concerning price, any thing is worth only what others are willing to trade for it, including time.Ting Tsu Yu, quoted in the X-Cents paper
The framework rests on five principles.
- Acceptance primacy
- Value comes from willingness to accept, not from official designation.
- Resource utilization
- Existing coins and bills are the infrastructure. Nothing new has to be produced.
- Community sovereignty
- Local collectives decide value systems within their own jurisdictions.
- Gradual transition
- A parallel system can run beside official money and, over time, replace what isn’t working.
- Scarcity transformation
- Manufactured scarcity becomes shared abundance through community-controlled value assignment.
Wrap your bills.
The first mechanism turns an ordinary bill into a community instrument. Its value grows with each local trade, on terms the community writes into its own agreement, so keeping money in circulation close to home pays. Anyone outside the circle is free to accept it too, on whatever terms they choose.
- Wrap it. A bill is enclosed in clear plastic or lamination.
- Mark it. A trusted local logo or sticker is applied by an employer or marking agent.
- Count it. Each local transaction adds a sticker. Traded back to the marking agent, the bill is worth one extra unit per use.
Bills are meant to change hands 10 to 100 times locally before being unwrapped and returned or traded outside the collective.
A $20 bill, $1 per local trade
| Local trades | Value at the marking agent |
|---|---|
| 0 | $20 |
| 10 | $30 |
| 50 | $70 |
| 100 | $120 |
Outside the community it is a $20 bill unless someone chooses to trade more for it. The premium is whatever the local terms, and any willing outsider, agree it is.
The Power of 1.
The second mechanism equalizes coins. During designated community hours, every coin counts as $1 for essentials such as food and housing. The paper’s example: weekdays, outside business hours. If every penny buys a dollar’s worth of what people need to live, hunger and housing problems are addressed directly, and people gain more say over how they spend their time instead of trading it just to survive.
The Saturday wheel.
Value redistribution can be daily and playful. Younger participants can trade small coins in for larger notes each day, with the community (or Treasury) covering the difference, and once a week a wheel matches birth years to coin years for a bigger prize. Choose an age group and spin.
Clear debts without cash.
Debts often run in circles. Bob owes Tom $100, Tom owes Larry $100, and Larry owes Bob $100. None of them has any cash, yet each is owed exactly what he owes. Put the three in a room and every debt can be cancelled, sealed with three handshakes and no money changing hands. If one of the three is a bank, the arithmetic is the same, but the bank can’t see the loop. More on that below.
When the three disagree about who should pay first, or when none of them has the cash to settle their debts, a neutral catalyst can thaw the freeze. Sheila lends Bob a $100 bill: Bob pays Tom, Tom pays Larry, Larry pays Bob, and Bob hands the same bill back to Sheila. Every debt is settled and Sheila ends up exactly where she started. The catalyst only has to be accepted at each step, which is again acceptance primacy. It doesn’t have to be a cash note. A personal check or an IOU from Sheila works the same way, as long as each person accepts it. Services can balance the books too, since debts can be settled by work performed instead of money paid.
Now put a bank in the scenario: the debts now run up to the bank like a pyramid, instead of around a loop. Each of the three debtors owes the bank $100, and each debtor is owed $100 by a neighbor, yet none of Bob, Tom, or Larry has any cash. The bank registers what each of them owes it, but not who owes them, so the money they are owed never reaches the bank and the debts simply wait. A clearing house sees both sides of every ledger, so it spots the loop and cancels it. Try both in the panel.
Three debts, one loop
| Person | Owes the bank | Is owed |
|---|---|---|
| Bob | ||
| Tom | ||
| Larry |
From three people to three hundred
Now imagine three hundred or more people carrying similar debts and clearing them through a shared community clearing house instead of a distant central bank. Members record what they owe and what they are owed. The clearing house looks for loops like Bob’s and cancels them. A small reserve, held by the community, plays Sheila’s part and covers gaps in timing. Doing this by hand is hard, and it needs honest record-keeping and people willing to take part. AI could make it simple: it can keep the ledger, find every loop among hundreds of members, work out the fewest cancellations that clear the most debt, and explain each step in plain language for members to approve.
Why a community might reach for it.
The paper argues that conventional monetary policy has left many people exposed: Japan’s deflationary trap, Turkey’s hyperinflation, Cuba’s dual currencies, Iran’s sanctions-driven instability. In the United States it points to housing: home prices ran about three times median household income through the 1990s, and Harvard’s Joint Center for Housing Studies puts the national multiple at about five today, with the priciest metros at eight or more.
Figures checked in September 2026 against the U.S. Census Bureau Housing Vacancy Survey, the Federal Reserve (G.19 and Distributional Financial Accounts), Federal Student Aid, and Harvard JCHS. Some differ from the original paper, which used earlier data.
How a town could begin.
- Organize and assess. Community assemblies name priority needs and where the current system fails. Local businesses volunteer for lamination and sticker roles. The group picks its first value reassignments.
- Build acceptance. Merchants agree to honor X-Cents values for set goods and services, essential providers join in, and a simple system tracks stickers on wrapped bills.
What it has going for it
- Immediate. It uses currency that already exists.
- Low tech. Paper, coins, lamination and stickers are enough.
- Resilient. It builds on existing legal tender rather than replacing it.
- Crisis-ready. It can be stood up quickly in an emergency.
X-Cents is a research proposal. Before piloting, check local tax treatment and the rules on handling and modifying currency where you live. This page is not legal or financial advice.
Who keeps the books?
Stickers only mean something if people trust the count. The Citizens Internet Portal (CIP), a companion framework for distributed, tamper-resistant democratic infrastructure, is a natural steward. Choose who runs it.
What the Portal contributes either way
- A verified circulation ledger. Sticker counts and marking agents are recorded with cryptographic verification, so no single party can quietly rewrite them.
- Democratic value-setting. Liquid democracy lets residents vote directly or delegate on rules such as which goods count as essentials and when community hours run.
- Shared budgets by quadratic vote. Weekly prize pools and similar community funds can be allocated by quadratic voting, which lets people express how strongly they care.
- Distributed architecture. Power is spread across many nodes, so capture of one operator does not capture the system.
These are proposed integrations drawing on the CIP paper’s architecture, cryptographic verification and voting designs. Each still needs to be specified and piloted.
Read the research.
X-Cents was developed by Duke Johnson, building on Ting Tsu Yu’s original CurrentSea X-Change text, and analyzed in a paper co-authored with Claude (Anthropic). It is a stepping stone toward fuller systems such as Creative Currency Octaves, Universal Basic Income and Public Trust Foundations.
The X-Cents framework can be understood as a comprehensive “currency assurance” system that secures community purchasing power and economic stability through democratic mechanisms. Unlike traditional insurance that protects against loss, currency assurance proactively ensures that money serves community welfare through value reassignment, circulation tracking, and equitable distribution systems. X-Cents could provide communities with immediate tools for economic self-determination when conventional institutions perpetuate unfair austerity for some and opulence for others.From the CurrentSea X-Change paper
