### Correlation Chart Between Submissions and Prize Pool
-

-> **NOTE:** *Events with $200K–$275K prize pools (ETHGlobal New Delhi, ETHGlobal Cannes, ETHGlobal New York) have 14–42 submissions with moderate correlation in mid-range. Very small prize pools ($2K–$10K) almost always have 0–1 submissions. Extremely large prize pools do not guarantee high privacy participation. Prize size alone is not a strong driver for privacy submissions.
+> **NOTE:** *Events with $200K–$275K prize pools (for example, several ETHGlobal events) tend to sit in the mid-range for privacy submissions (roughly 14–42), while very small pools ($2K–$10K) rarely produce privacy projects. The updated dataset (including recent events) reinforces that very large prize pools do not by themselves guarantee high privacy participation — prize size is only one of several factors that correlate with privacy submissions.*

-| 10 | **ETHIstanbul** | 4 | 42 | **9.52%** |
-
-> **NOTE:** *A few events (notably ETHBelgrade and ETHTokyo) show extremely high privacy intensity — in Belgrade 50% of submissions were privacy-related (though total submissions there was only 20). Larger hackathons (e.g.: ETHGlobal Prague, ETHGlobal Cannes, ETHGlobal New Delhi, and ETHGlobal ETHOnline) produce many privacy projects in absolute numbers but are lower on intensity % because they have many non-privacy projects.*

+
+> **NOTE:** *A few events (notably ETHBelgrade and ETHTokyo) show extremely high privacy intensity — Belgrade had 50% privacy intensity (albeit from a small total). ZK Hack Berlin also ranks high on intensity (≈37.8%) after the latest additions. Conversely, large ETHGlobal flagship events produce many privacy projects in absolute numbers (e.g., ETHGlobal Buenos Aires contributed 68 privacy projects) but score lower on intensity percentage because of large overall submission counts.*

+- **Auth**: 26 projects (6.2%) — credential verification, age-gating, MFA
+
+> **Emerging**: Education (2), Analytics (1), Moderation (1), Music (1)
+
+### 6. **Geographic Footprint**
+- **Europe leads**: 21 hackathons (52.5%)
+- **Asia**: 5 events (ETHTokyo, Bangkok-adjacent)
+- **Americas**: 7 hackathons (3 North America, 4 South America)
+- **Africa**: 3 events (ETHAccra, EthNile Kampala, ETHiopia)
+- **Virtual**: 4 events (ETHGlobal (ETHOnline, Unite DeFi), EthNile Kampala, ETHSafari)
+
+### 7. **Organizer Ecosystem**
+- **ETHGlobal**: 11 events, 3,945 submissions → flagship coordinator
+- **ETHWarsaw Foundation**: 2 events
+- **ETHKyiv**: 2 events
+- **Distributed organizing**: 25+ smaller organizers driving grassroots participation (Octant, ETH Bishkek, Ethereum Argentina, etc.)
+
+---
+
+## Opportunities & Gaps
+
+### Under-Served Categories
+- **DAO/Governance**: Only 10 projects (2.4%) — potential for private voting tooling
+- **Storage & Interop**: 9 and 2 projects respectively — niche but critical infrastructure
+- **Wallet & Security**: 10 and 6 projects — room for privacy-preserving UX innovation
+- **Education & Compliance**: 2 and 0 projects — learning resources and regulatory tools barely present
+
+### Technology Gaps
+- **FHE/MPC**: Only 16 projects combined (3.8%) despite regulatory/confidentiality advantages
+- **Post-quantum**: 1 project (ERC-21 post-quantum) — emerging threat mitigation underexplored
+- **Privacy-preserving ML**: 51 AI projects, but limited TrustedExecution / encrypted-inference focus
+
+### Geographic Expansion
+- **North America**: Only 3 dedicated hackathons (vs. 21 Europe) — underrepresentation in U.S./Canada
+- **Asia-Pacific**: 5 events but limited follow-up projects — suggests participation without deep ecosystem roots
+- **Middle East/Oceania**: Zero hackathons — entirely unrepresented
+
+---
+
+## Trends & Outlook
+
+### 1. **ZK as Default Privacy Paradigm**
+ZK proofs appear in ~35% of all privacy projects, establishing dominance. However, regulatory acceptance and interop challenges persist.
+
+### 2. **AI-Privacy Convergence**
+18.7% of projects explicitly blend AI with privacy, signaling industry-wide recognition that agent-based systems require confidentiality.
+
+### 3. **Emerging Regional Leaders**
+Latin America (ETHLatam, Ethereum Argentina) and Eastern Europe (ETHWarsaw, ETHKyiv) emerging as secondary hubs outside ETHGlobal dominance.
+
+### 4. **IRL Momentum**
+9.47% privacy ratio for in-person events vs. 4.76% virtual — suggests community cohesion, mentorship, and on-site collaboration drive privacy focus.
+
+### 5. **Q4 Acceleration**
+November's 11.8% intensity (107 projects) indicates growing market awareness and developer interest heading into 2026.
+
+---
+
+## Recommendations for Ecosystem Development
+
+1. **Expand FHE/MPC funding**: Only 16 combined projects; targeted grants could unlock regulated financial applications.
+2. **Launch post-quantum initiatives**: Single project signals ~0% awareness; establish working groups and grant programs.
+3. **Develop regional hubs**: Establish permanent privacy-focused fellowship/accelerator programs in underrepresented regions (North America, Asia-Pacific, MENA).
+4. **Create education tracks**: Formal curriculum and tutorials for ZK/privacy engineering; only 2 education projects across entire ecosystem.
+5. **Strengthen wallet/UX layer**: Privacy primitives exist, but user-facing tools lag; fund 5–10 wallet/application-layer projects.
+6. **Formalize governance privacy**: DAO/governance category severely underserved; coordinate with major DAOs (MakerDAO, Aave, etc.) to sponsor hackathon tracks.
+
+---
+
+## Conclusion
+
+The privacy-first Ethereum hackathon ecosystem demonstrates **strong maturity and momentum** in 2025. ZK proofs are the de facto standard, geographic diversity is expanding, and emerging AI-privacy convergence is accelerating adoption. However, critical gaps remain in alternative privacy primitives (FHE, MPC), post-quantum readiness, and geographic coverage in the Americas and Asia-Pacific.
+
+With **31 of 40 hackathons** producing privacy projects and a **steady upward trend through Q4**, the ecosystem is primed for scaling. Targeted investment in underserved categories, regional expansion, and foundational education can unlock the next phase of privacy-preserving innovation in Web3.

# Privacy Project Tags
-This directory defines the **standard tags** used across privacy projects submitted to Ethereum hackathons. Tags help us organize and analyze trends in the ecosystem by function, technology, and use case.
+This file documents the tagging methodology used to label `privacy-projects.md` collected from hackathons. Tags reflect three orthogonal dimensions we use across the dataset:
-When contributing a privacy project, include **1–4 tags** from the list below in the `tags` column of `privacy-projects.md`.
+- Use-case / Domain (what the project is for)
+- Core Technology (what privacy or building-block tech it uses)
+- Tooling / Infra / Region (supporting categories or community focus)
----
-
-## Category: Use Case
-
-| Tag | Description |
-|---------------|-------------------------------------------------------------|
-| `identity` | Decentralized identifiers, anonymous credentials, on-chain or off-chain identity tools (e.g., ZK-KYC, Sismo) |
-| `defi` | Privacy-enhanced decentralized finance (e.g., private swaps, lending, trading) |
-| `dao` | Private voting, reputation systems, or treasury management in DAOs |

-| `marketplaces`| Anonymous auctions, private commerce, or buyer/seller confidentiality |
-| `gaming` | On-chain game mechanics using privacy (e.g., hidden state, sealed moves) |
+When contributing or reviewing a project, prefer 1–3 primary tags: one use-case tag, one technology tag (if relevant), and up to one tooling/region tag. Extra tags may be added when a project legitimately spans multiple areas (e.g., a privacy wallet that uses ZK and TEE).

-## Missing a tag?
+## Tagging Guidance (methodology)
-If your project doesn't fit into the existing tags, propose a new one by opening an issue or suggesting an update in your PR.
+- Prefer lowercased, comma-separated tags. Examples: `finance`, `zk`, `infra` or `social`, `zk`, `education`.
+- Use 1 primary use-case tag (domain), 0–1 technology tags (if a clear privacy primitive is used), and 0–1 tooling/region tags. Up to 4 tags are allowed when justified.
+- When a project mentions multiple privacy technologies, tag the one that is central to the project's privacy claims (or list both if both are central). The dataset's technology counts are approximate and derived from regex matching.
+- Avoid overly granular tags for one-off experiments; reserve new tags for repeated or growing patterns.
---
-**Tagging Guidelines:**
+## Examples (mapping real projects to tags)
-- Use lowercase, comma-separated tags.
-- Be descriptive but concise.
-- Avoid overly niche tags unless the category is emerging or growing.
+- LOCUSt (Buenos Aires): `finance`, `zk`, `defi`
+- ZKRSS (Buenos Aires): `communication`, `zk`, `infra`
+- Void Wallet (Buenos Aires): `wallet`, `zk`
+- ProverX (Buenos Aires): `ai`, `zk`, `tooling`
+- Private Deals (Buenos Aires): `finance`, `zk`, `infra`
----
+If you think a tag is missing or a mapping is incorrect for a project, propose the change in the dataset's PR with a short justification.
-_Example tag list for a project:_
-`identity,zk,maci,education`
+These tags are tuned to the vocabulary and methodology observed in `hackathons.md`, `privacy-projects.md`, and `stats.md`.
