Physical art NFTs: real art with a digital twin

A physical art NFT, sometimes called a phygital NFT, pairs a real object with a token on a blockchain. The token is the object's digital twin: a public record of what it is, who made it and who owns it.

ChainChum is built around this idea. Every original painting, drawing, sculpture and numbered print listed here gets its own NFT certificate, minted when the seller publishes the work for a one-time fee and transferred to each owner after.

#How the real piece and the NFT stay linked

• The QR code. Each certificate has a QR code that opens the piece's public verify page. It is printed on the packing slip and, if you add them, on tamper-evident holographic stickers for the back of the piece or its frame.
• The content hash. The NFT stores a fingerprint of the listing's details and photos. The verify page recomputes it, so a mismatched record is obvious.
• The ownership history. When the piece is resold or inherited through ChainChum, the NFT moves with it and the history grows.

#Why collectors want it

• Provenance that survives. A paper certificate in a drawer can be lost; the NFT record can't.
• Easier resale. A buyer can check the history before paying.
• Insurance and estates. A clear, dated record helps with insurance, appraisals and passing a collection on.

#What it does not do

Holding the NFT is not the same as holding the painting. Owners can export the token to their own wallet and trade it on other NFT marketplaces, but ChainChum does not trade tokens itself, and if a piece is sold privately outside ChainChum the token doesn't move by itself. ChainChum keeps the record honest by showing such hops as "transferred off-platform" until the new holder claims it.

See NFT certificates of authenticity for what each certificate contains.

#Questions

#Is a phygital NFT worth more than the artwork alone?

The value is in the artwork. The NFT makes that value easier to prove, which matters most when a piece is resold, insured or inherited.

#Can I add an NFT to art I already own?

Not yet. Certificates are issued for works listed on ChainChum only, so every badge means the piece passed the same human-made checks.
