The split orchestrator and transcoder architecture enables the creation of transcoding pools. These pools are analogous to PoW mining pools that outsource PoW hashing to one or many separate miners. In the Livepeer network, pool operators are orchestrator operators and the participants in pools are transcoders. Transcoding pools are not a part of the core protocol so the details around how work in a pool is tracked and how transcoders in a pool are compensated depend on the pool implementation.
There are two types of pools: private and public pools.
Private pools only allow known transcoders to participate based on some set of criteria defined by the pool operator. Examples of requirements for private pool membership include:
Public pools allow any transcoder to participate.
Public pools that are live today:
