The primitive.

full primer →

Every exhibition cataloging artefact is pinned to IPFS through Pinata and anchored in a Hedera Consensus Service message; painters get a permanent CID plus a consensus timestamp instead of a fragile cloud URL.

Why this primitivePinata enables reliable, permanent IPFS pinning of JSON manifests for galleries’ provenance needs.

Kernel
a Pinata JWT upload that pins images / JSON / manifests to IPFS and returns a permanent CID, anchored in an HCS topic message
Drives the UI as
a 'pinned to IPFS' chip with the CID, the HCS sequence number and a gateway preview
