Primus primary sources
Reviewed: 2026-05-10 UTC
Core protocol framing
- https://primuslabs.xyz/
- Official site for the project.
- https://docs.primuslabs.xyz/
- Main documentation entrypoint; frames Primus (formerly PADO) as a cryptographic layer for secure, permissionless data verification and computation across blockchain and AI.
zkTLS design and trust tradeoffs
- https://docs.primuslabs.xyz/primus-network/tech-intro/
- Most useful single-page explanation of Primus zkTLS, especially the MPC-versus-Proxy mode split and the role of QuickSilver in both paths.
- https://eprint.iacr.org/2023/964
- Technical foundation paper linked directly from Primus docs:
Lightweight Authentication of Web Data via Garble-Then-Prove.
- Technical foundation paper linked directly from Primus docs:
- https://eprint.iacr.org/2021/076
- QuickSilver paper referenced by the docs as the proof system used in Primus’ zkTLS design.
Network operation and operator admission
- https://docs.primuslabs.xyz/primus-network/attestor-node-guides/
- Best source for the operational trust model: supported chains, task contracts, Phala TEE deployment path, and the requirement to contact the Primus team for whitelist access before managing a node.
Example application framing
- https://docs.primuslabs.xyz/implementation-scenarios/verify-digital-identity/
- Shows how Primus wants to be used for age, nationality, address, and reusable KYC / proof-of-humanity-style attestations.
Developer tooling surface
- https://github.com/primus-labs/zkTLS-tutorial
- Tutorial repo that makes the template-plus-SDK approach explicit and shows extension-based versus backend-based integration patterns.
Main takeaways from this pass
- Primus’ distinctive mechanism is templated zkTLS attestation, not generic DID issuance or a single reputation score.
- The most important design split is MPC mode versus Proxy mode, because it shows how the system trades stronger integrity guarantees against better performance.
- The attestor network is a major control surface: TEEs, supported-chain task contracts, and whitelist admission all shape who can actually verify offchain facts.
- Primus is best compared against systems that turn offchain facts into reusable credentials or gates, especially where template registries, attestors, notaries, or browser extensions become the hidden governance layer.
