Trust you can't delete. Forward once. Prove forever.
Digital messages can be wiped. Emails can be disputed. AI outputs can be altered. Files can be replaced. ProofCore turns digital artifacts into independently verifiable cryptographic commitments anchored to the public ledger.
Don't take our word for it. Explore actual cryptographic commitments already anchored to TON Blockchain.
Preserves sender ID, platform origin timestamps, and text forensics before chat deletion. Cryptographically locked to the source post.
Two parties confirmed terms directly in chat. Both Telegram session traces and agreement hashes are committed to an immutable PDF certificate.
Authenticated against sender DNS. Captures a forensic snapshot of the public key to prevent verification failures when companies rotate DNS keys.
Prompt, model output, and model ID digested into an atomic cryptographic proof. Protects whitehat findings from quiet post-factum tampering.
Screenshots lie. Databases can be edited. Try changing Bob's bonus by a single digit in the right panel and watch the proof immediately fail.
We don't store what you want to prove. We store what lets you prove it.
Telegram messages, voice notes, promises, and P2P terms before someone taps 'Delete for Everyone'.
Invoices, contractual notices, and NDAs authenticated via DKIM and public DNS key snapshots.
Inference prompts, code review verdicts, RAG outputs, and machine-to-machine validation.
Automated release notarization for binaries, SBOMs, and CHANGELOGs to secure the supply chain.
Your proof does not depend on our database, our website, or our continued existence. Every evidence package generated by ProofCore is completely self-contained with zero vendor lock-in.
The protocol is the authority, not the website. We never write raw files to the blockchain (Zero-Storage Ledger). For APIs, data is discarded immediately after memory-hashing. For Telegram and Email, off-chain assets reside in your private vault solely to compile your standalone Evidence ZIP.
Provides cryptographic transparency and machine-readable provenance metadata required for generative AI outputs.
Structured to support self-authenticating electronic records through verifiable cryptographic hash processes.
Cryptographically binds CI/CD builder identity to release artifacts, preventing undetected supply chain modifications.
Disclaimer: ProofCore provides technical cryptographic primitives. Legal admissibility and evidentiary weight depend on applicable jurisdiction and court rules.
Our Telegram bot (@ProofCoreBot) allows anyone to create immutable cryptographic receipts without a Web3 wallet:
@ProofCoreBot p2p <terms> in any chat. When both click "Sign", the deal is sealed on-chain.sealit@proofcore.org. We verify the DKIM signature against DNS and anchor it.ProofCore implements strict tier-specific storage boundaries:
• On the Blockchain: Strict Zero-Storage. We never write personal files, messages, or PII to the public TON ledger. Only 64-character mathematical roots are anchored.
• For AI & API (M2M): Strict Zero-Storage. Raw payloads are hashed in volatile RAM and immediately discarded. You can also hash files locally on your machine and send only the digest.
• For Telegram & Email: Private Ephemeral Vault. Raw assets are held securely in your private off-chain vault solely to compile your downloadable Evidence ZIP, with automatic 30-day data minimization for free accounts.
