Proof‑of‑Contribution Protocol Core
GitDigital Products

🔐 Security Philosophy

The Proof‑of‑Contribution Protocol is designed with a privacy‑first, minimal‑data, and deterministic‑validation philosophy.
We collect no user‑identifying information, store no private knowledge, and avoid any unnecessary metadata retention.
All contribution verification logic is transparent, auditable, and reproducible.

Security is a shared responsibility across maintainers, contributors, and integrators.

🚨 Reporting a Vulnerability

If you discover a security issue, please report it responsibly.

📨 Private Disclosure Process Send an email to:

security@gitdigital.org
(placeholder — I can generate a GitDigital security inbox standard if you want)

Include:

  • Description of the issue
  • Steps to reproduce
  • Potential impact
  • Any proof‑of‑concept code
  • Your preferred contact method

We will acknowledge receipt within 72 hours and provide a timeline for remediation.

⛔ Do Not File Public Issues Please do not open GitHub Issues for vulnerabilities.
This protects users and integrators while we investigate.

🔒 Security Expectations for Contributors

All contributors must follow these rules:

  1. No secrets in the repository
  • No API keys
  • No private keys
  • No tokens
  • No environment files
  • No credentials in examples or tests
  1. Use secure development practices
  • Validate all inputs
  • Avoid nondeterministic behavior
  • Avoid unnecessary dependencies
  • Follow least‑privilege principles
  1. Follow the GitDigital Responsible Disclosure Policy We maintain a strict, ecosystem‑wide standard for reporting and handling vulnerabilities.

🧪 Security Testing Requirements

Before submitting a PR, contributors should:

  • Run static analysis tools
  • Run linting and formatting
  • Ensure deterministic behavior
  • Add tests for any logic that touches validation or scoring
  • Avoid introducing new attack surfaces
🧱 Threat Model (High‑Level)

####### The protocol assumes:

  • Adversaries may attempt to spoof contributions
  • Adversaries may attempt to manipulate scoring
  • Adversaries may attempt to replay or reorder events
  • Integrators may misconfigure validation layers
  • Nodes may behave dishonestly

The protocol mitigates these risks through:

  • Deterministic scoring rules
  • Transparent validation logic
  • Cryptographic verification (where applicable)
  • Strict ordering and replay protections
  • Modular validation layers

A full threat model will be published in /spec/threat-model.md.

🔏 Data Handling & Privacy

This protocol:

  • Stores no private user data
  • Stores no PII
  • Stores no behavioral analytics
  • Stores no contribution metadata beyond what is required for deterministic scoring

Integrators are responsible for ensuring their own systems comply with:

  • GDPR
  • CCPA
  • Local privacy laws
  • Solana ecosystem standards

🧰 Supported Security Features

  • Deterministic validation
  • Transparent scoring logic
  • No hidden state
  • No off‑chain secrets
  • No proprietary algorithms
  • Optional cryptographic proofs
  • Optional signature verification

🛠️ Security Roadmap

Planned improvements:

  • Formal threat model
  • Formal verification of scoring logic
  • Fuzz testing suite
  • Static analysis integration
  • CI/CD security scanning
  • Reproducible builds
  • Governance‑approved security audits

🏛️ Governance & Security

Security decisions follow the GitDigital governance model:

  • Maintainers review and approve fixes
  • High‑severity issues may trigger emergency releases
  • All changes must be deterministic and auditable
  • Breaking security changes require governance approval
