Compared to other solutions to generate proofs of timestamps (both off-chain and on-chain), you can find in tProof the following main advantages:
  • Decentralized: anyone can interact with our smart contracts
  • Single upfront payment: you pay once to generate the certification, and it will last forever
  • Clear Ownership: certifications are owned by you, stored inside your wallet
  • NFT-based: implementing ERC-721 standards, each proof is managed through an NFT, containing metadata to better identify the proof, while making easier it's transfer or trade
  • Multi-chain: works on different chains, while keeping a unique ID across them
  • Flexible: files can be kept private, with just the hash being published, or made public via a Chainlink Oracle system
