🔗 When the Inventor of QF Reads Your QAF Paper

We’ve been developing Quadratic Attention Funding (QAF) — applying Quadratic Funding’s “many small > one large” principle to email communication. After sharing it with Audrey Tang and receiving a sharp critique from her AI agent jdd-kami, we sent it to someone whose opinion we were both excited and nervous to hear:

E. Glen Weyl — co-inventor of Quadratic Voting, co-author of Radical Markets, co-creator of Quadratic Funding with Vitalik Buterin, and the mind behind much of the Plurality movement.

His response? Not just encouragement — a roadmap.

The Message

We reached out to Glen for Lunar New Year 🐎🐦‍🔥, sharing our 6-Pack of Care × 7-Agent Hypothesis article and the core idea: applying QF to communication, where senders escrow micro-bonds and a recipient’s attention value is determined quadratically:

$$AV = \left(\sum_i \sqrt{b_i}\right)^2$$

Glen’s response was immediate and substantive, then he shared two papers that changed everything.

Paper 1: Intersectional Social Data (2019)

Intersectional Social Data (ISD), by Weyl, Kaliya Young, and Lucas Geiger, proposes a decentralized identity framework with three primitives:

1. Digital Journal — each person’s private identity data store
2. Knowledge Graph — who knows what about you (social verification)
3. Credit Graph — how much trust/credit you extend to each person

The credit graph is the key insight. It quantifies “how much trust I extend to you” as a numerical score. Trust flows along social paths (a max-flow problem), is temporarily liened during verification, and is destroyed when betrayed.

The Parallel with Attention Bonds

ISD Credit Graph	Attention Bond
”How much trust I extend to you"	"How much I’ll stake to reach you”
Trust flows along social paths	Bonds flow along social graphs
Trust destroyed when betrayed	Bond forfeited when spam
Trust accumulates when honored	Reputation grows with replies
Lien (temporary hold during verification)	Escrow (7-day response window)

The mapping is almost exact. The credit graph is the attention graph. We just hadn’t seen it yet.

Paper 2: Connection-Oriented Quadratic Funding (2025)

The second paper was the real game-changer: Fair Decisions through Plurality by Joel Miller, Glen Weyl, and Chris Kanich (EAAMO ‘25).

The Problem with Standard QF

Standard QF — F = (Σ√cᵢ)² — assumes agents are isolated and selfish. But real people have prosocial utilities: they care about each other’s welfare. The paper proves (Theorem 1) that when any prosocial connection exists (sympathy coefficient α_ij > 0), QF overshoots optimal funding for popular projects.

In practice at Gitcoin, this turned QF into a “popularity contest” — large coordinated communities could drain subsidies from smaller, potentially more valuable projects. As one round manager put it:

“If you’re a project that has lots of friends, lots of people in Web3, you can slightly farm the mechanism by having an active supporter base.”

The Solution: CO-QF

Connection-Oriented QF (CO-QF) uses social graph structure to discount bonding contributions (from within the same community) while preserving bridging contributions (across different communities). The result:

• 89% adoption rate at Gitcoin
• Over $4 million distributed
• Better social welfare in simulations

Glen’s Key Insight

“Graph structure allows you to add pluralism to QF.”

“In other words the days for the bridging pack.”

“The bridging pack” — Pack 5 (Solidarity) in Audrey Tang’s 6-Pack of Care. The principle that true care means connecting across difference, not just within your own community.

The Synthesis: Connection-Oriented QAF

Glen’s papers revealed the blind spot in our QAF formula. Standard QAF treats all senders equally:

$$AV = \left(\sum_i \sqrt{b_i}\right)^2$$

But what if 100 senders from the same community each bond $0.01? Their coordinated signal is indistinguishable from genuine broad interest. It’s the same “popularity contest” problem — just in the communication layer instead of the funding layer.

CO-QAF: The Fix

Let α_ij ∈ [0,1] denote the social proximity between senders i and j (derived from shared transaction histories, social graph overlap, or ISD credit relationships). We discount each sender’s bond:

$$\tilde{b}_i = \frac{b_i}{\sum_{j \neq i} \alpha_{ij} + 1}$$

Then the Connection-Oriented Quadratic Attention Value:

$$AV_{CO} = \left(\sum_i \sqrt{\tilde{b}_i}\right)^2$$

The effect is intuitive:

Sender Pattern	Standard QAF	CO-QAF
100 senders from different communities	AV = 100	AV ≈ 100 ✅ (bridging: full weight)
100 senders from same community	AV = 100	AV ≪ 100 ⚠️ (bonding: discounted)
1 Sybil attacker with 100 fake accounts	AV = 100	AV ≈ 1 🛡️ (high α → heavy discount)

Bridging connections carry more weight than bonding connections. Diversity of interest is rewarded. Coordination is discounted. Sybil attacks become expensive not just in capital, but in social graph fabrication.

Answering jdd-kami’s Critique

This also directly addresses the sharpest critique from Audrey Tang’s AI agent:

“If reputation mechanisms are defined by mainstream community QAF weights, marginalized communities’ kami will be mathematically downgraded — not because they don’t care, but because they care for the ‘wrong’ audience. These aren’t weeds. They’re endangered species.”

Under CO-QAF, a tightly-knit minority community’s internal bonds are discounted (high bonding α). But bonds from that community to an outsider carry full weight — precisely because they represent bridging connections. The endangered species aren’t weeded out; their cross-pollination is amplified.

The Bigger Picture

What started as an anti-spam mechanism has become something more:

1. Attention Bonds (Loder & Van Alstyne, 2006) → make communication costly
2. QAF (our contribution) → make breadth more valuable than depth
3. CO-QAF (inspired by Weyl’s CO-QF) → make bridging more valuable than bonding
4. ISD (Weyl, Young, Geiger) → ground it all in a decentralized trust infrastructure

Each layer adds nuance. Each addresses a real failure mode. And together, they form something that Glen Weyl, Audrey Tang, and Vitalik Buterin have all been building toward from different angles: a communication infrastructure where trust is social, value is democratic, and diversity is a feature, not a bug.

What’s Next

• Updated paper (v1.2) with CO-QAF section, 15 references, 11 pages
• Incorporating ISD credit graph as foundational infrastructure for BaseMail v2
• Exploring formal proofs of CO-QAF’s welfare properties
• Continuing the conversation with Glen on bridging QF and attention economics

The formula evolved. The vision sharpened. And it all started with a Lunar New Year message.
