Best Thing: Reviewers praised the book for its insightful exploration of trust in various contexts, particularly its relevance to blockchain and decentralized technologies. Many found the connections between social capital and community dynamics to be thought-provoking and timely. Worst Thing: Some reviewers noted that the book could be dense and challenging to read at times, with certain concepts being difficult to grasp without prior knowledge of the subject matter. A few felt that it lacked practical applications and examples to illustrate its theories effectively.
Key Insights
- Three eras of trust: Local → Institutional → Distributed. Botsman’s framework: trust began as a local phenomenon (you trusted people you knew, in your community); shifted to institutional trust (you trusted brands, governments, banks, and credentialing bodies you’d never personally encountered); and is now shifting to distributed trust (platforms, ratings, and peer networks where trust flows between strangers directly, without institutions as intermediaries).
- Trust leaps — the moment of extension to the unknown. Every time trust expands to a new form (trusting a stranger’s car, a crowdfunded startup, a peer-to-peer transaction), it requires a leap across what was previously untrustworthy. Understanding what makes those leaps possible — and what makes them fail — is the book’s central project.
- Social capital as the substrate of community trust. Pre-institutional trust was maintained through dense social networks where reputation was common knowledge. The weakness of this system is that it doesn’t scale: you can only maintain genuine social capital with people you interact with repeatedly. Institutional trust was invented to scale what community trust couldn’t.
- Distributed trust requires new accountability mechanisms. Peer-to-peer trust systems (Airbnb ratings, Uber driver scores, eBay feedback) create accountability through transparency and aggregation rather than through institutional authority. But they are gameable, vulnerable to manipulation, and tend to concentrate trust in ways that mirror existing social inequalities.
- The Yap stone metaphor — community knowledge as currency. The Yapese used large limestone discs as currency; the ownership was known by the community, not marked on the stone. Blockchain and other distributed ledgers are structurally similar: trust maintained through shared knowledge across a network rather than through a central authority.

From earlier notes:
- Eras of trust: Local, Institutional and Distributed trust
- “Trust leaps” when going from known to unknown situation
- We are evolved for community trust
- “Social capital” found in communities, etc.
- “Fey” as precurosr to bitcoin; rocks that the community knows who owns and represents wealth
Helped put trust thinking, extremely relevant to blockchain and decentralized tech, into a broader social context.
