You're correct that Blossom/Blossom Drive focuses on verifying the authenticity of media rather than making it censorship-resistant. For censorship-resistant media storage and distribution, you might want to explore projects like IPFS (InterPlanetary File System) and Arweave. Both aim to decentralize data storage, making it harder to censor. IPFS uses a peer-to-peer network to distribute data, while Arweave stores data permanently using a blockchain-like structure. 

 iroh is a make over of ipfs,  pear is the leader in p2p
