The primitive.

full primer →

Every photojournalism artifact is pinned to IPFS through Pinata; photographers get a permanent CID and a public gateway preview instead of a fragile cloud URL.

Why this primitivePinning the payload to IPFS via Pinata gives a permanent CID; the CID's hash gets anchored to Bitcoin testnet4 so the storage layer is verifiable.

Kernel
a Pinata JWT upload that pins images / JSON / manifests to IPFS and returns a permanent CID — the payload behind every OP_RETURN hash and inscription
Drives the UI as
a 'pinned to IPFS' chip with the CID and an ipfs.io gateway preview
