Giới thiệu về tProof

tProof is a dApp that generates decentralized timestamp proofs, so that anyone can prove that a document existed before a given date. Users can mint two tProof proofs: Hash-only, for those who just want to publish file hashes on-chain; and Hash-with-file, which uploads the original file to Arweave permaweb and appends the public URL of the file to the minted tProof via Chainlink Oracles.
