ABOUT THIS SKILL

Ben Rubin and Greg Eisenberg explore how blockchain can solve trust and reputation problems in three inefficient markets—dating apps, luxury watch marketplaces, and tutoring platforms—by creating open, privacy-preserving reputation graphs that reward good behavior and reduce friction.

KEY PRINCIPLES (11)

Trust & Reputation

Trust is created by verifiable actions, not self-attestation.

Instead of relying on curated profiles or subjective claims, record actual user behavior (date follow-through, class attendance, successful watch sales) on-chain in a privacy-preserving way.

Why: Self-attested profiles are biased and manipulable; cryptographic proofs of real-world actions create an immutable, transparent record that both parties can trust.

"we don't have enough accountability and owning up to the way we communicate and interact online"

Market Efficiency

Inefficient markets are ripe for disruption when a trust layer is added.

Dating, luxury resale, and tutoring all suffer from information asymmetry and high search costs; a shared reputation graph compresses these frictions.

Why: Reducing information asymmetry reallocates value from middlemen to participants and increases overall market liquidity.

"there's a huge gap in which how do you know which one is for you and how they're going to get the best out of you"

Privacy & Utility

Privacy can be preserved while still extracting useful aggregate insights.

Use zero-knowledge proofs and hashed identifiers so individual data remains private, yet statistical likelihoods (e.g., 90 % chance of a second date) can still be surfaced.

Why: Users will not adopt systems that expose personal details; cryptographic privacy guarantees enable both participation and data utility.

"with keeping privacy, you can still show different kind of proofs of the type of behavior and the type of connections that they're making"

Network Effects

Open protocols compound value as more clients integrate them.

A shared reputation backend can be consumed by Hinge, Tinder, or a new dating client alike; the data layer becomes more valuable as more apps feed and read from it.

Why: Standardized data formats reduce fragmentation and allow smaller builders to bootstrap network effects without building their own user base from zero.

"if that's a standard that other dating apps can ride into, it doesn't matter if you're on Hinge, on Raya, on Tinder or anything"

Incentive Alignment

Reward good actors instead of only punishing bad ones.

Design mechanisms that give reputational or financial upside to users who consistently behave well (show up to dates, deliver authentic watches, retain students).

Why: Positive reinforcement increases the proportion of desirable behavior and makes the platform more attractive to high-quality participants.

"we need to reward people for being group stewards of healthy and nuanced and mature conversation"

Derivative Value

Authentic experiences become exponentially more valuable as replicas proliferate.

As AI floods the internet with synthetic content and personas, provably real interactions (a verified date, a physical watch, a live tutoring session) will command premium value.

Why: Scarcity of authenticity increases its economic worth; blockchain proofs provide the necessary scarcity in a digital world.

"having time with Greg one-on-one... it's going to grow exponentially higher when the image and replication of Greg through AI is going thousand X"

Cost Reduction

Escrow plus reputation can eliminate intermediary fees.

By replacing platform trust with cryptographic trust, luxury marketplaces can drop commissions from 15–20 % to near-zero.

Why: Removing rent-seeking middlemen transfers value to buyers and sellers, increasing transaction volume and platform adoption.

"you can actually maybe make the market a little bit more efficient and remove the third party"

Fit Over Fame

Match quality often trumps absolute skill level.

A moderately skilled tutor who is a perfect fit for a student can outperform a world-class tutor who is a poor fit; reputation graphs surface fit via retention data.

Why: Personalization increases learning efficacy and satisfaction, leading to longer retention and better outcomes.

"I'm curious about that outcome if I gave you a teacher that is half as good as Tony Robbins, but is world class fit to you"
