EVIDENTIAYou've never verified truth like this before.
Evidentia brings human connection to every truth verification. Submit claims, provide immutable evidence, and let collective intelligence determine what's real through weighted validation.
How truth verification works
Evidentia is a decentralized truth oracle for Web3. Communities validate claims through weighted consensus, creating verifiable truth scores that smart contracts can query on-chain.
Submit & Store
Immutable Claims
Create verifiable claims on Sui blockchain with evidence stored permanently on Walrus. Content-addressable and tamper-proof.
Decentralized Evidence
Upload documents, images, or data as supporting evidence. Retrieved via Walrus blob IDs forever.
Validate with Reputation
Weighted Consensus + AI Grading
Community validates claims through vouching or disputing. Weight = Ethos Score × √Stake × AI Multiplier prevents whale domination and rewards quality evidence.
