In the era of AI-generated content, copyright disputes, and data leaks, proving that a specific file existed at a specific time is a significant challenge. Traditional methods often require uploading your files to third-party servers, compromising your privacy and security.We are changing that. Introducing Evident, a privacy-first utility designed to provide legally binding proof of existence while keeping your data strictly on your device.The Core Philosophy: "Zero-Knowledge Proof of Existence"At Evident, we believe your files belong to you. Our architecture is built on a simple premise: the server never touches your files.Instead of uploading documents, the Evident utility computes a cryptographic hash locally on your machine. This hash—a unique "digital fingerprint"—is the only thing sent to our infrastructure.How It Works:Local Hash Calculation: You select a file and a project. The utility generates a hash locally.Server Ledger & TSA: We receive only the hash and metadata. We then record the event in a secure ledger, attaching a Time Stamping Authority (TSA) signature.Local Audit Trail: Your device stores the proof package, the ledger link, and the TSA data.Verification: Our local and public verifiers generate professional PDF reports that serve as verifiable evidence of existence at a specific point in time.Scalable Trust: From Base to EnterpriseWe provide a tiered model to match your security and legal requirements:TierFocusBest ForBaseHash + Ledger + Free TSAPersonal projects & basic tracking.LegalJurisdictional-Compliant TSALegal disputes and intellectual property.EnterpriseEncrypted Audit StorageCorporate data compliance.IdentityUser-Owned Keys & Digital SignaturesHigh-security identity verification.(Note: Audit recovery is available as a paid service tier.)Why This Matters for the Global MarketWhether you are a developer protecting your code, an artist securing your digital art, or a lawyer managing client documents, Evident provides a neutral, blockchain-based timestamping layer that is independent and transparent.Our public verifier allows anyone to input a hash and verify the project’s history, providing auditability without ever exposing the underlying file content.Get StartedWe are open-source and committed to transparency. You can find our release, source code, and documentation on GitHub.We invite developers, privacy advocates, and legal-tech enthusiasts to test Evident, contribute to the repo, and help us build a standard for decentralized data integrity.
