Hash it. Anchor it. Prove it.
ProofStamp is a Telegram bot for cryptographic anchoring on TON. It records SHA-256 on-chain for files, documents, and posts, then generates a PDF certificate with QR and transaction link. For group and channel posts, ProofStamp can save proof only or proof together with the full original post text in TON.
