🎨 Visual Art · color authenticity validation

ColorCode Certifier

Certify and verify exact color compositions of artworks using blockchain color code hashes.

Hedera smart contract (HSCS)· onchain logic

Section · Onchain

The primitive.

Color authenticity validation gets a tiny Solidity contract deployed to Hedera testnet through the JSON-RPC relay; painters see a 'verified onchain' badge with the live address and a one-tap HashScan link.

Why this primitiveHedera testnet contracts guarantee immutable storage of color code data linked to artist hashes.
