# Privacy scoring modelling > Web3privacy now analytical [platform](https://github.com/Msiusko/web3privacy/tree/main/Web3privacynowplatform)

**Approach**

| Phase  | Description |
| ------------- | ------------- |
| 1. **Expert take**  | Outreach privacy experts behind core privacy services - aggregate their professional opinions on how to analyze if a service is truly private or not.) |
| 2. **Scoring model prototyping**  | Create an open & flexible scoring model for a communal feedback loop - share with the privacy community, evaluate. |
| 3. **Scoring model MVP release**  | Deliver balanced model for privacy services assessment - powered by pros & general public opinions. |

# Current status (02/04/2023)

## 0. 350+ privacy solutions in 1 database - [delivered](https://github.com/Msiusko/web3privacy/blob/main/README.md)
## 1. On-going community research (survey) within the privacy experts. 
I asked experts behind privacy-services or contributors to the privacy-centric communities to share their visions on analysing whether a service is private. Answers were collected via chats & survey [form](https://forms.gle/ETBEZed9LUUtLWT87)

**Criteria**:
- min 50 different experts
- a broad range of positions: tech, ops, marketing, devrel, strategy
- a broad range of services: from privacy coins to mixnets
- different geographies: from the USA to Russia

# Questions from the privacy experts

# Take 1
- does it has traceability? (ie addresses is hidden from the public ledger)
- does it has unlinkability? (ie transactions can't be linked to each other)
- does the amount of transfer is hidden? 
- does IP addresses of participants hidden? 
- is it decentralized and based on open-source technology? 

# Take 2

| Question  | Observation |
| ------------- | ------------- |
| much the users in control of their data disclosure?  | (Scale 1-10) |
| how well community feedback and evaluation is built into product dev? | the less -» the more centralized it is -» the smaller the % of it staying private without collective intelligence. This is like the web3privacynow  - platform part, actually, for sales, but also I found this really relevant. |
| is there a community bug/security bounty program/platform?  | yes, no |
| how much transparent disclosure is available on the tech and company | like smart contract audits, security audits, source of financing?   |
| how private the tech stack it uses on all layers. from hardware to l3/l4 etc.  | how well it is disclosed what they built on and where they host stuff, or if the tech is decentralized like nym - is there available dashboard data about this? |
| product roadmap and release flexibility - this is a harder one, and I'm not sure it makes sense. What I mean is it's also important to have a clear vision while reacting to current needs/bugs /fixing vulnerabilities.  | maybe its redundant with no2 and no2b |

# Take 3
1. What are the trust assumptions the user has by using the platform?
2. What and how is user information stored and transmitted?
3. How much PII is stored/collected?
4. How is information collected + processed + disseminated
5. How completely can you participate with total privacy?

# Take 4

| Direction  | Observation |
| ------------- | ------------- |
| network privacy  | how do you connect to the chain? Can you do it via Tor? |
| blockchain privacy  | do the resulting on-chain transactions offer the user any on-chain obfuscation? |
| censorship resistance  | how resistant is the project to external pressure? Will the project censor you? |
| permission  | do I need to create an account to access the thing, or is the thing open access? |
| custody of funds  | is the user out of control of their keys at any point? |

# Answers from the privacy experts
**Additional lenses**: _is it accessible to a non-web3 person & is it accessible to a non-tech web3 person?_

_Huge thanks everyone who contributed! I make it anon now, but will thank everyone (who would liked to be credited) once a scoring model will be published on GitHub for community evaluation._

# 2. My personal notes on privacy scoring (they were made before communal survey)
_Sketches what could be put inside privacy-solutions scoring model_ (note: think of these as questions to experts for a workshop on scoring ideation).

**Key observations**

| Topic  | Observation |
| ------------- | ------------- |
| Broad range of different takes on privacy assesment | Privacy experts have around 50+ tips |
| Tech-centricity of assesment | Majority of the expert takes are hard to execute by non-tech people (they need info-help!) |
| Privacy assessment takes enormous time | Time-To privacy-fit - potential for analytical service |
| Privacy literacy isn't enough | The scoring model demand both "decentralisation", "open-source" & "privacy" topics understanding |
| Mix of objective & subjective takes |  Scoring criteria are different from objective (example: transaction traceability) & subjective (example: backed by a16z crypto) takes  |

**Open-source transparency**
- **GitHub repos**: # of commits, # stars, date of repo creation.

**Third-party validation**
- **Security audits**: yes, no; type of audit; ammount of audits.

**Community validation**
- Existing bugs
- White hackers assessment (like Secret Network TEE bug)
- Negative Discord, Twitter, other public feedback (product & founder-centric)

**Team**
- Market validation
- GitHub contribution
- Track record (incl. red flag projects)

**Financials**
- Investments
- TVL (like Aztec's L2)
- Donation-based
- Public treasury

**Liveliness**
- How active is GitHub activity 
- How active is the community
- Is there public product traction?

**Product-readiness**
- State of product-readiness
- MVP-readiness
- Protocol (test-net/main-net)
- dApp (release timing, third-party validation like AppStore/Play Store)
- network-reliability (the state of privacy in Ethereum, Solana, Avalanche etc)

**Cross-checked data leakage**
- Complementing privacy stack data leakage (example: phone + dApp; wallet + RPC etc)
- Third-party data leakage (from the hackers to state agents (think of Iran or North Korean govs))

**Data aggregation policies**
