Excited to announce our collaboration with @ipfs.tech and https://dasl.ing on two new standards for the next thousand years of decentralized social video: S2PA and MUXL! Together they give us a standard for self-certifying and content-addressable media in the decentralized social ecosystem.

S2PA is a standardization of "Streamplace-flavored C2PA" that we've had in production for more than a year. C2PA has some great ideas about media provenance but the part where you pay Digicert hundreds of dollars to sign media is antiquated. Instead: K-256 signing, dids, decentralized identity.

MUXL aims to extend content addressing to media containers: it's like DRISL for MP4 files. Ever tried to concatenate two MP4 files and then split them, recovering the same two files you started with? I have. It's really hard. We're solving the problem with a canonical standard, Rust, and WASM.

Taken together, the two standards make media a first-class primitive in the decentralized social web. You get a path to creator provenance, decentralized distribution, and remixing of content. Video is the richest way for us to interact, we shouldn't be treating them as detached, opaque blobs!

Huge thanks to @mosh.bsky.social, @robin.berjon.com, and @bumblefudge.com for their support and enthusiasm. Sleep on dasl.ing at your own peril. Tagging in @reckless.bsky.social - relevant to your interests, I think. What if signed provenance was the default for social video?
