Protect the protest. Preserve the proof.
A decentralized, privacy-first protocol to empower activists, protect their identities, and preserve immutable proof of protest — even under repressive regimes. Built using Oasis Sapphire and ROFL, Activist Toolkit provides censorship-resistant infrastructure to verify presence, coordinate emergency alerts, and resist digital erasure without exposing user identities.
Activist Toolkit is a secure, censorship-resistant system for modern human rights defenders.
In the face of growing authoritarianism and digital surveillance, activists around the world are risking their lives — but often have no way to verify their actions, protect their communications, or prove their contributions.
Conventional digital tools like photos or chat logs are:
- Easily manipulated
- Can be incriminating to share
- Frequently dismissed in legal or asylum proceedings
Blockchain isn't just useful — it's essential.
It's the only infrastructure that makes proof tamper-proof, decentralized, and permanent.
-
✅ Proof of Protest
Anonymous, geolocation-based, timestamped credentials that verify protest participation — without revealing personal identity. -
🔴 Dead Man Switch (Red Alert)
A failsafe timer that triggers alerts to trusted contacts if an activist goes silent or is detained. -
🧾 Peer Attestation System
A decentralized verification process where trusted members vouch for presence, preventing fake participation or infiltration.
Anonymous, verifiable presence — without needing to reveal your face or contacts.
Sidika is applying for asylum in the Netherlands. As a gender rights activist from Turkey, she must prove her involvement in protests — but she never appeared in photos and won't share private chats.
Using Activist Toolkit, she receives an immutable, peer-attested credential: she was present at X protest, on Y date, verified by trusted witnesses.
Now she has verifiable proof — without compromising herself or others.
Secure fallback for detained activists or those crossing danger zones.
Abdul is helping his sister cross a border into Germany. He sets a 6-hour timer in the toolkit.
If he doesn't cancel in time, the app automatically sends a prewritten message to his Telegram group of legal and support contacts.
This feature can trigger help when silence becomes danger.
- Oasis Sapphire – Confidential EVM for encrypted smart contracts and private on-chain logic.
- Oasis ROFL – Secure TEE environment for off-chain logic (e.g. red alerts, proof validation).
- ZK Identity Tools (e.g. Semaphore) – To enable anonymity and unlinkable attestations. COMING SOON
- Smart Contracts – For soulbound credentials, timers, and proof mechanisms.
- IPFS (optional) – For decentralized metadata and document storage. COMING SOON
✅ We use
roflEnsureAuthorizedOriginto guarantee only verified, secure TEE-originated data is accepted on-chain.
🔧 Note: Link to code implementation will be added soon.
We truly believe in the long-term existence of this project. We would aspire to continue improving the current features as well as adding more like:
-
🪙 Anonymous Fundraising
Create and contribute to activist campaigns privately via blockchain-native donations. -
💬 Activist Education Chatbot
A conversational AI assistant trained on global activist handbooks for real-time, context-aware guidance. -
🌐 Global Network Expansion
Develop tools for collective resource sharing and decentralized reputation systems across movements.
This project qualifies for:
- Privacy Track — Leveraging Sapphire to encrypt user activity and on-chain protest proofs.
- Security Track — Secure fallback alerts, identity protection, and tamper-proof attestations via ROFL.
- Potential Impact: Enables global activist safety and verification at scale.
- Confidentiality: Data never leaves ROFL unencrypted; Sapphire encrypts smart contract state.
- UX: Designed for non-crypto-native users with a clean, simple, safe experience.
- Innovation: Uses geolocation-based protest proofs and peer attestations — a novel combination on Sapphire.
- Implementation Quality: Core features functional and tested with Oasis stack.
- Bonus: Integrated
roflEnsureAuthorizedOriginfor verified confidential origin in smart contracts.
Built during ETHDam III, 2025 — for activists everywhere who defend freedom, dignity, and truth.
