Character rig sharing gets a SHA-256 anchored into a Bitcoin testnet4 OP_RETURN — filmmakers see a 'timestamped on Bitcoin' chip and a permanent mempool.space link.

Why this primitiveAnchoring a SHA-256 fingerprint of this artefact in a Bitcoin testnet4 OP_RETURN gives it a wallet-independent, permanent, one-line proof-of-existence.
