Streamplace sits between decentralized social applications and the Livepeer Network to provide a full ingestion → provenance → transcoding → distribution pipeline. This page consolidates the full architectural model, including:
  • Streamplace SPE responsibilities
  • Node & SDK architecture
  • C2PA + Ethereum provenance flow
  • Livepeer broadcaster + orchestrator roles
  • User playback and verification

​
🧠 Architecture Layer Explanations

​
1. Livepeer Foundation / DAO (Funding Layer)

The Livepeer Treasury funds Streamplace as a Special Purpose Entity to deliver:
  • open-source video infrastructure
  • provenance systems
  • a node + SDK usable by any decentralized social app
This ensures long-term sustainability and alignment with public-goods principles.

​
2. Streamplace SPE Layer

Streamplace’s responsibilities include:
  • designing and maintaining the streaming node
  • providing developer SDKs + APIs
  • managing the metadata schema (place.stream.metadata.*)
  • developing the C2PA + Ethereum provenance pipeline
This layer ships infrastructure—not a hosted platform.

​
3. Application / Client Layer (Decentralized Social Apps)

Apps integrate the Streamplace SDK to:
  • start livestreams
  • configure metadata (rights, warnings, policies)
  • authenticate creators via wallets or identity systems
Examples:
  • AT Protocol apps
  • Fediverse clients
  • Web3 creator tools

​
4. Streamplace Node Layer (Ingest & Provenance)

The Streamplace Node performs the bulk of technical heavy lifting:

​
Ingest

Supports:
  • WHIP / WHEP
  • RTMP
  • Browser WebRTC

​
Segmentation

Splits video into 1-second MP4 segments.

​
Provenance

Each segment receives:
  • C2PA manifest
  • Ethereum signature for identity binding

​
Metadata Embedding

Attaches:
  • content rights
  • distribution policy
  • content warnings
  • playback configuration

​
5. Livepeer Network Layer

Once Streamplace packages segments, it hands off video to Livepeer. Broadcaster Role:
  • receives signed segments
  • dispatches them to orchestrators
Orchestrators:
  • GPU-accelerated transcoding
  • ABR (multi-bitrate) generation
  • may include environment metadata
Verifiability Layer:
  • ensures correct transcoding
  • enables trust-minimized delivery

​
6. Distribution Layer (Streamplace Output)

Streamplace reconstructs:
  • HLS manifests
  • WebRTC session outputs
  • metadata-enriched playback structures
It also ensures:
  • provenance integrity is preserved end-to-end
  • distributionPolicy rules are enforced

​
7. Playback Layer (User-Facing)

Users receive:
  • HLS or WebRTC streams
  • metadata, warnings, rights displays
  • verifiable provenance (C2PA + Ethereum)
This makes video trustworthy, rights-aware, and censorship-resistant.
