# Glossary

> The Livepeer-specific terms used throughout these orchestrator and delegator docs.

## Roles & network

**Orchestrator** — A GPU operator that runs `go-livepeer`, executes video and AI jobs, and earns ETH
fees plus LPT rewards. The on-chain participant that holds staked LPT.

**Transcoder** — The compute process that performs video encoding (or, via the AI runner, inference).
Has no on-chain identity; runs in-process or split out from the orchestrator.

**Delegator** — An LPT holder who bonds tokens to an orchestrator to share in its rewards without
running hardware.

**Gateway** — The demand-side node that aggregates application requests, selects orchestrators, and
pays for work. Out of scope for these docs, but it's what sends you jobs.

**Active set** — The top orchestrators by total bonded stake (commonly 100) eligible to receive jobs
and inflation rewards in a round.

## Staking & economics

**LPT** — The Livepeer Token. A work/coordination token used for staking, rewards, and governance —
**not** used to pay for jobs (that's ETH).

**Bond / Bonding** — Attributing your LPT stake to an orchestrator. Tokens stay in the
`BondingManager` contract; the operator never takes custody.

**Unbond / Unbonding period** — Starting a full exit. After unbonding you must wait the unbonding
period (currently 7 rounds) before withdrawing. **Rebond** cancels it.

**Redelegate** — Move bonded stake to a different orchestrator without the unbonding wait.

**Reward cut (`rewardCut`)** — The % of LPT inflation an orchestrator keeps; the rest goes to
delegators. Lower is better for delegators.

**Fee share (`feeShare`)** — The % of ETH fees an orchestrator passes to delegators. Higher is better
for delegators.

**Reward call (`reward()`)** — The once-per-round on-chain call that mints an orchestrator's
inflation reward. Missing it forfeits that round for the whole pool, with no catch-up.

**Claim earnings (`claimEarnings()`)** — Checkpointing accrued rewards into your bonded balance.
Timing relative to the reward call matters.

**Inflation** — New LPT minted each round and distributed to bonded stake. The rate adjusts toward a
target bonding rate (\~50%).

**Treasury** — An on-chain fund for community/public-goods spending, governed by proposal. Funded by
a cut of LPT inflation (LIP-92 set 10%, with a balance ceiling that pauses contributions when full).

## Payments

**Probabilistic micropayment (PM) ticket** — How gateways pay. Each ticket has a face value and a win
probability; orchestrators redeem only winning tickets on-chain for ETH. Expected earnings = face
value × win probability.

**Round** — The protocol's accounting unit (\~1 day). Governs active-set election, inflation, reward
calls, and governance snapshots.

## Infrastructure

**NVENC / NVDEC** — NVIDIA's hardware video encoder/decoder used for transcoding. Consumer GPUs cap
concurrent NVENC sessions.

**AI runner** — A Docker container that performs AI inference for a configured pipeline/model, spawned
and managed by the orchestrator process.

**Pipeline** — A category of AI task (e.g. `text-to-image`, `audio-to-text`, `llm`) mapped to
compatible models. Configured in `aiModels.json`.

**Service URI / `serviceAddr`** — The public address gateways use to reach an orchestrator, stored
on-chain via the ServiceRegistry.
