Make your evidence impossible to dismiss or disappear
Zimbabwean opposition activists endure 7+ months of arbitrary detention on fabricated charges as the government weaponizes the justice system to crush dissent.
ProofAnchor creates cryptographically verifiable evidence packages with timestamping, chain-of-custody logging, and court-admissible export formats. Activists can collect photos, videos, medical reports, and affidavits that are hashed and registered on multiple public ledgers so they cannot be challenged on authenticity — directly addressing the regime's common tactic of claiming evidence is fabricated.
Zimbabwean opposition activists, political dissidents, and human rights defenders
Forensic-grade evidence integrity designed specifically for admissibility in Zimbabwean courts, with automatic generation of affidavits that reference the cryptographic proofs.
professional and protective
Capture media with automatic metadata stripping, hashing, and notarization
Immutable record of every access or modification with digital signatures
Registers evidence hash on Bitcoin, Ethereum, and multiple public block explorers
Generates ZIP package with all evidence, hashes, timestamps, and draft affidavit
Encrypted collaborative spaces for legal teams with granular permissions
Finds patterns across your cases using vector embeddings of charge descriptions
Digital signing and video recording of witness statements with liveness detection
Creates sworn statements that legally reference the cryptographic evidence

Cryptographic proof and court-ready packages trusted by Zimbabwe's bravest human rights defenders.
1. Partner with the Zimbabwe Human Rights NGO Forum to train their 45 member organizations on the tool. 2. Offer free Advocate tier to 6 prominent Zimbabwean lawyers who handle political cases. 3. Work with the Southern African Litigation Centre (SALC) who will recommend the tool for all Zimbabwe-related cases.
Simple Bitcoin timestamping
No mobile experience, no court packaging, no collaboration features
Complete workflow from capture to court with legal templates
Strong human rights focus
General training, not a tool with cryptographic guarantees
Actual cryptographic proof and automated court package creation
Growing library of court-accepted precedents using our specific evidence package format creates a strong data and brand moat. Network effects as more lawyers become familiar with and trust the ProofAnchor format.
Zimbabwean courts have begun accepting blockchain evidence in several high-profile cases in 2023-2024 while smartphone camera quality has improved enough to capture usable forensic evidence.
Courts reject cryptographic evidence despite current trend
Work with sympathetic lawyers to establish precedent cases using the tool
Blockchain transaction fees become prohibitively expensive
Use batching, multiple chains, and cheaper Layer 2 solutions
Solo developer cannot maintain blockchain integrations
Use reliable third-party APIs (BlockCypher, Alchemy) with fallbacks
Success: Clear confirmation that cryptographic timestamping would strengthen at least 70% of their cases
Success: At least 4 pieces of ProofAnchor evidence submitted in actual cases
