About ProofLedger
Multi-industry document proof platform.
ProofLedger is a comprehensive blockchain-based platform that provides immutable proof-of-existence for regulated documents across multiple industries. From real estate contracts to academic transcripts, we make document verification transparent, secure, and industry-specific.
What is ProofLedger?
A specialized platform for regulated document verification with industry-specific workflows.
Industry-Specific Approach
Unlike generic proof-of-existence tools, ProofLedger understands the unique requirements of different industries. Each use case comes with specialized terminology, document types, role definitions, and verification rules tailored to regulatory needs.
Version-Aware Document Management
ProofLedger supports document evolution through blockchain-compliant updates. Create new versions that reference originals while maintaining complete audit trails. Perfect for contracts, certifications, and legal documents that evolve over time.
Blockchain-Native Security
Built on Ethereum for maximum security and transparency. Documents are stored on IPFS while only cryptographic hashes and metadata live on-chain, ensuring privacy while providing immutable proof of existence and ownership.

Anyone can verify document authenticity without needing accounts or special access. Share verification links that work independently of our platform, ensuring long-term accessibility and trust.
