: The Encounter of NFT and HLC Hash

“True art must be provable—forever.”

Sotheby’s Auction House, London.
Oil painter Eliza Lowell had made a bold decision: for the first time, she would digitize and sell her artwork.
But for her, simply minting it as an NFT wasn’t enough.
She wanted her collectors to recognize the authenticity of her work for a lifetime—in a way that could not be forged, and whose essence would never fade with time.

She turned to the HLC-Hash-based U-Hash solution (personalized hash issuance).
Her signature, the date of creation, the chemical composition of the paint, even the philosophy behind the piece—all of it was encrypted into a single hash value.
This hash was generated through an irreversible mathematical color vector composition, impossible to replicate.

Buyers of the artwork received an NFC stamp embedded with the HLC hash.
When scanned with a smartphone, it displayed a message:

“This artwork is certified as an original piece created by Eliza Lowell in Paris on May 11, 2025.”

Her painting was no longer just a digital image.
It had become an artistic identity in itself—a fusion of hash and art, eternal and irreplaceable.
