RetroPhones Provenance Record

This page presents the provenance record of each RetroPhone that will ever exist. Each RetroPhone image is firstly hashed using SHA-256 algorithm. A combined string is obtained by concatenating SHA-256 of each RetroPhone image in the specific order as listed below. The final proof is obtained by SHA-256 hashing this combined string. This is the final provenance record stored on the smart contract.

Important Information

Each RetroPhone token ID is assigned to an artwork image from the initial sequence with this formula: (tokenId + startingIndex) % 10000 → Initial Sequence Index

(tokenId + startingIndex) % 10000 → Initial Sequence Index

Finalized Starting Index:

RetroPhones Contract Address:

Final Proof Hash:
