    YouTube video creator willing to explore alternative ways to monetize content. 2. Uploads video file and registers content hash on-chain making an authorship claim. 3. Links the authorship claim to YouTube video proofing ownership of the social media version. 4. Stakes CLY token on authorship claim to show commitment on its authenticity. 5. Mints NFT licensing the terms defined in its metadata to future owners. 6. Trades NFT on existing marketplace, potential purchasers can trace it back to the copyright claim.
