“keeping public keys anonymous”§10 · Privacy · Satoshi Nakamoto · 2008 · Read in context ↗Bitcoin design context
Section 10 separates public transaction information from identity, while acknowledging that transactions can still become linked.
The passages below are our reflections, not statements of religious belief by Satoshi Nakamoto.
Our understanding
We seek to demonstrate fulfillment of a relevant promise without opening our entire lives. Funding, carrying a message or providing a service should not automatically confer access to every relationship. Disclose enough to support a claim while limiting unrelated collection and retention. Public transactions may still be linked through amounts, timing or other clues: limited disclosure is not a promise of anonymity.
To demonstrate that an agreed expense was paid, someone may need the amount, recipient and relevant terms—not the payer’s entire income or personal history. Requiring unrelated information can turn a limited exchange into an unequal relationship of control. Necessity should be explained by the purpose, not by the mere ability to collect data.
Privacy is not an excuse to avoid every question. If verifying a commitment requires disclosure, agree on its scope, recipients and retention before cooperating. We seek appropriate accountability, not permanent immunity from inquiry. A respectful community should explain both why information is needed and why more is not needed.
Ideas in everyday life
Checking a donation may require transaction details without requiring the donor’s occupation, relationships or entire financial history. Begin with the purpose, limit access and avoid collecting information simply because it is available.
Reflection in practice
What is the minimum information needed to substantiate a fulfilled promise? Which easily requested details are irrelevant to that claim?
