Tensions in Practice: A new profile can break the record link¶
A small exchange using public profiles
Imagine an exchange where a new customer can consult a participant’s recorded dealings with earlier customers. Compare a persistent pseudonymous account with a policy allowing an unlinkable new profile. The same participant and old conduct are held fixed. What changes is whether the new customer can connect that conduct to the profile now offered. Neither policy makes a record accurate or a person trustworthy.
Carry conduct forward
Let strangers connect a participant’s current profile with prior dealings.
Permit a clean separation
Allow a new profile without exposing its link to the previous public history.
Why these aims pull against each other
Breaking the identity link protects separation from the old public record while also preventing that record from governing the same participant’s future treatment.

Persistent account
The participant uses one enduring pseudonymous account. Earlier dealings enter its public record, which a new customer can consult against the current account.
- What it protects
- Past dealings remain relevant to later encounters with strangers.
- What it costs
- Persistent linkage can carry stale or mistaken judgments forward and requires identity-binding administration.
- When it fits
- Plausible when cross-encounter accountability matters and the exchange can maintain, contest and correct the binding.

Unlinkable restart
The same participant may start a new public profile without a binding link to the earlier account. The old public record remains, but the new customer cannot attach it to this profile through the exchange.
- What it protects
- The participant can separate the new public identity from the previous history under the declared policy.
- What it costs
- The new customer loses this route for using prior conduct; harmful conduct as well as mistaken judgment can escape the link.
- When it fits
- Plausible where legitimate identity separation is prioritized and the exchange can tolerate reduced history-based reliance or use other protections.

What this illustration does—and does not—establish
The source establishes the structural tension; the concrete alternatives and their conditional costs are editorial synthesis. No arrangement is a universal recommendation.
- The model stipulates successful or absent linkage. It supplies no technical anonymity guarantee or identity-verification method.
- Persistent identity need not reveal a legal name. Public records can be inaccurate or biased in either policy.
- The fresh-start rationale is an editorial design aim, not a claim that unlinkability eliminates all other ways to identify someone.

Reputation: Reputation presupposes a stable, trackable identity, yet identity is exactly what strategic agents can manipulate supplies the local tension. The setting, alternative arrangements, and stipulated consequences are editorial applications.
Reputation presupposes a stable, trackable identity, yet identity is exactly what strategic agents can manipulate
The loop only closes if today's agent is reliably linked to the record of yesterday's conduct. When identity is cheap to change or hard to verify, the stock detaches from the agent: cheaters shed bad records, impostors borrow good ones, and the standing no longer governs the agent it was built from.
