Privacy Analysis
Vocdoni - ZK Census PRF
Total Score: 8
Identity Leakage (Who)
Stage: Cryptographic Unlinkability
2
Definition
The protocol employs strong cryptographic techniques to ensure that even actions performed by the same user, including sequential steps in a stateful process, are unlinkable to each other from an external observer's perspective.
Characteristics
An attacker cannot correlate different actions to the same originating user.
Action Leakage (What)
Stage: Obfuscated Action Parameters
1
Definition
An attacker can discern the general _type_ of action being performed, but critical parameters are either hidden, aggregated, or sufficiently ambiguous to prevent precise inference.
Characteristics
The specific values within an action are obscured.
Actions may be batched or aggregated, revealing a total but not individual contributions.
De-anonymization Trust Assumption
Stage: Trustless / Self-Sovereign
2
Definition
The protocol is architected such that no entity, or even the complete collusion of all protocol operators and infrastructure providers, can de-anonymize users. The information required for de-anonymization is secured exclusively by the user and is never shared.
Characteristics
All sensitive user data is either encrypted client-side with keys exclusively controlled by the user, or never leaves the user’s local environment at all.
Protocol Survivability
Stage: Highly Robust
2
Definition
The protocol is exceptionally difficult to disable. Its operational dependency is minimal and relies only on its highly robust base-layer infrastructure.
Characteristics
The protocol's core logic is fully autonomous and encoded in on-chain smart contracts.
Any user can continue to use the protocol with basic, widely available infrastructure.
The protocol's survivability is tied directly to the survivability of its underlying blockchain (e.g., 'as long as Ethereum is alive, the protocol is alive').
Underlying Technology Maturity
Stage: Battle-Tested
1
Definition
The underlying technology has been rolled out at a significant scale and has a multi-year track record of operating in production with substantial value at stake. It has withstood public scrutiny and attack attempts.
Characteristics
Groth16 (PLONK, STARK, and its variants are migrating towards this level as they accumulate more production time)
Production-grade TEE

Total Score: 6
Identity Leakage (Who)
Stage: Cryptographic Unlinkability
2
Definition
The protocol employs strong cryptographic techniques to ensure that even actions performed by the same user, including sequential steps in a stateful process, are unlinkable to each other from an external observer's perspective.
Characteristics
An attacker cannot correlate different actions to the same originating user.
Action Leakage (What)
Stage: Obfuscated Action Parameters
1
Definition
An attacker can discern the general _type_ of action being performed, but critical parameters are either hidden, aggregated, or sufficiently ambiguous to prevent precise inference.
Characteristics
The specific values within an action are obscured.
Actions may be batched or aggregated, revealing a total but not individual contributions.
De-anonymization Trust Assumption
Stage: Centralized Trust / Fails 'Government Test'
0
Definition
The ability to de-anonymize users or actions rests with a single entity or a small, non-independent group of entities. These entities can be legally compelled or technically compromised to reveal user data.
Characteristics
A single server, operator, or administrator holds decryption keys or logs linking users to actions.
Collusion of a very small number of parties is sufficient to break privacy.
Protocol Survivability
Stage: Moderately Robust
1
Definition
The protocol is architected on distributed infrastructure but may have certain components that are less resilient. However, these weak points are designed for easy recovery or replacement by the community.
Characteristics
The protocol's codebase **must be open-source**.
While some default infrastructure (e.g., a primary RPC endpoint or front-end) might be centralized, any sufficiently skilled user can bypass the failure by running their own node or interacting directly with the on-chain contracts.
Underlying Technology Maturity
Stage: Mature
2
Definition
The underlying technology is considered a standard primitive in the broader cryptographic and computer science communities. It has decades of academic analysis and has been successfully implemented across countless applications.
Characteristics
The technology has been in production for at least 10 years.
The technology has been widely adopted and used in production.
