ProofCore is a trustless, cryptographic Proof-of-Existence (PoE) engine and digital evidence layer built on The Open Network (TON). 🛡 Key Features: • Message & File Sealing: Forward any Telegram message, photo, document, or email to anchor its immutable SHA-256 fingerprint into TON forever. • Bilateral P2P Contracts: Create and sign legally binding agreements directly in any group chat with 1-click Telegram authorization. • Merkle Tree Batching: Thousands of proof hashes are batched into a binary Merkle Tree, writing a single Merkle Root on-chain to keep costs near zero. • Offline Evidence Package (ZIP): Receive self-authenticating ZIP packages containing your original file, forensic JSON manifest, offline HTML/Python verifiers, and an official FRE 902 / eIDAS PDF certificate with verification QR codes. • Zero-Storage Privacy: Raw data is never stored on the public blockchain — only mathematical cryptographic proofs.
