A Moon Mission Boarding Pass
Stored On-Chain. Forever.

Not an NFT. Not a pointer. Not a link that might break tomorrow. The actual pixel data of this boarding pass lives inside Cardano blockchain transactions — reconstructed live before your eyes.

⚡ This Is NOT An NFT

99% of NFTs

  • Image stored on IPFS
  • Blockchain holds a pointer
  • Dies when pinning stops
  • Anyone can copy the image
  • "Ownership" of a broken link
  • Depends on third-party servers

This Project

  • Image stored in tx metadata
  • Blockchain holds the actual bytes
  • Permanent as Cardano itself
  • Reconstructable by anyone
  • No token, no policy, no IPFS
  • Zero external dependencies
Every pixel of this image is encoded across 7 Cardano transactions as base64 data in transaction metadata — split into 64-byte strings to comply with Cardano's protocol limits. A final manifest transaction records all 7 TxIDs, reconstruction instructions, and a SHA256 hash so anyone can verify the image is authentic. Even if this website disappears tomorrow, the image lives on forever and can be reconstructed by anyone with a Cardano node and the manifest TxID: 8113d999f517cd4d9eaf766bfa12b2cfa02c13b6e9c839947300ac927629f5c3

🔧 How To Reconstruct Without This Website
  1. Fetch the manifest transaction 8113d999f517cd4d9eaf766bfa12b2cfa02c13b6e9c839947300ac927629f5c3 from any Cardano node, db-sync, or Blockfrost API
  2. Extract metadata at label 1965 — this gives you all 7 chunk TxIDs in the chunks array
  3. Fetch each chunk transaction and extract its metadata label 1965
  4. Sort chunks by the seq field (0 to 6)
  5. For each chunk, concatenate all strings in the data array in order
  6. Concatenate the results from all 7 chunks in sequence order
  7. Base64-decode the full concatenated string — this gives you the raw JPEG bytes
  8. Verify: SHA256 of the bytes must equal dd1bb0a1632a82267b96686821eedc30551fce79ef5c4a37f9122e39eca6476a
  9. Save as .jpg — you have the image. No IPFS. No servers. Just Cardano.

Delegate to GNP1

GNP1 has been running on Cardano since October 2020. This project is our answer to everyone who said "use the blockchain." We did.

We donate to mental health awareness charities whenever we can. Your delegation helps make that possible.
