Account-based vs token-based money is a framework for classifying forms of money by what has to be checked when a payment is made. With account-based money, the system verifies the identity of the payer and whether their account holds enough funds. With token-based money, the payee verifies that the object being handed over is genuine, without needing to know who the payer is. Economists Charles Kahn and William Roberds set out the distinction in a widely cited 2009 paper on payments economics.
The framework is now standard in central bank work on central bank digital currency (CBDC), where designers must decide which model to follow. It is related to, but not the same as, the split between physical and digital money: a token can be digital, as with cryptocurrencies, and an account can be kept on paper, as with historic ledger money.
Account-based vs token-based money in plain terms
Think of two ways to get into a concert. In the first, there is a guest list at the door. You give your name, the staff check it against the list, and you are in. In the second, you hold a printed ticket. Staff do not care who you are; they look at the ticket, check the hologram and tear the stub. The guest list is account-based. The ticket is token-based.
Each method has strengths. The guest list cannot be lost or stolen in your pocket, but the organiser knows exactly who attended. The ticket keeps you anonymous and can be handed to a friend, but if it is forged, or if you drop it on the way, that is your problem. Money works the same way.
How the two models work
| Feature | Account-based | Token-based |
|---|---|---|
| What is verified | The payer's identity and balance | The genuineness of the token |
| Main fraud risk | Identity theft and account takeover | Counterfeiting and double-spending |
| Privacy | Record keeper sees transactions | Can be anonymous, like cash |
| If credentials are lost | Account can usually be recovered | Value is usually lost |
| Examples | Bank deposits, central bank reserves | Banknotes, coins, bitcoin |
In an account-based system, the record keeper, typically a bank, is responsible for preventing fraud by authenticating users. That is why opening a bank account requires know your customer (KYC) checks. In a token-based system, the burden falls on the person receiving the money, who must be able to spot a fake. For physical cash this means security features; for digital tokens it means cryptography, such as checking a digital signature made with the holder's private key.
Examples
- Bank deposits. Commercial bank money is the clearest account-based form: a payment is an instruction to the bank to move a balance from one named account to another.
- Central bank reserves. Reserves held by banks at the central bank are account-based central bank money.
- Banknotes and coins. A banknote is a bearer instrument: whoever holds it owns it, which makes it the classic token.
- Cryptocurrencies. Bitcoin is usually described as token-based, because control of a private key, not identity, decides who can spend it. Its shared ledger also solves the double-spend problem, so the line between the models is not clean.
Use in CBDC design
The framework entered central bank policy through work at the Bank for International Settlements. Morten Bech and Rodney Garratt's "money flower" taxonomy in the BIS Quarterly Review of September 2017 classified money by issuer, form, accessibility and transfer mechanism, and a March 2018 report by the CPMI and the BIS Markets Committee built on that taxonomy, making the token-versus-account question a standard part of later CBDC work.
In March 2020, Raphael Auer and Rainer Böhme of the BIS described an account-based CBDC as one tied to the holder's identity, and a token-based CBDC as one that the central bank honours when the user proves knowledge of a secret value, such as by signing with a private key. They noted that tokens favour universal access and privacy but carry a high risk of lost funds, while accounts depend on strong identity systems, linking CBDC design to digital identity. Live and planned designs, including China's e-CNY, mix elements of both.
Criticism and limitations
- Blurred categories. Economists at the Federal Reserve Bank of New York argued in 2020 that a digital currency can be both, since a token system can require identity checks and an account system can allow some anonymity.
- Policy, not technology. The real choices, such as how much privacy users get and who bears fraud losses, depend on law and design rules more than on the label.
- Token terminology. The word "token" is also used for crypto assets and for tokenized deposits, which are often account-based claims recorded on a shared ledger, adding to the confusion.
