Mechanism Objectives
Livepeer’s core mechanisms are designed to:- Incentivise honest behaviour among participants (Orchestrators, Delegators, Gateways/Broadcasters)
- Scale supply capacity by rewarding infrastructure providers proportionally
- Secure verification of off-chain video and AI workloads through bonded stake
- Disincentivise dishonest actors via penalties (slashing)
Protocol Features
Core features of the Livepeer Protocol include:Blockchain Attributes
Blockchain Attributes
Blockchain Base
All protocol state (bonds, delegations, votes, job payments, etc.) lives on Arbitrum. The LPT token is ERC-20-based and bridged between L1 and L2.The Arbitrum rollup finalizes via Ethereum; thus the underlying security is Ethereum’s.After Confluence (LIP-73), Ethereum mainnet now mainly serves as a historical source – new stake/votes are on Arbitrum only.Consensus & Finality
Consensus & Finality
Consensus & Finality
Livepeer does not use its own consensus; it relies on Arbitrum’s optimistic rollup. Blocks (called rounds) occur roughly every 24 hrs, and after a ~7-day challenge window the state is finalised on Ethereum.This means trust assumptions are similar to other Ethereum Layer-2s: Arbitrum’s rollup validators and Ethereum miners secure the chain; fraud proofs protect against invalid blocks.Security Model

Security Model
Livepeer’s core contracts are on an Ethereum Layer-2 (Arbitrum One), which inherits Ethereum-level security via optimistic rollup.LPT stakers (orchestrators and delegators) provide economic collateral against misbehavior. Protocol rules penalise malfeasance by slashing stake (e.g. Losing part or all delegated tokens).Off-chain video verification and optional arbitration ensure correct transcoding.Node-Level Trust
Node-Level Trust
Node-Level Trust
Gateways/Broadcasters (clients) and orchestrators exchange signed data (video segments, “tickets,” job outcomes).These off-chain interactions can be audited (via perceptual hashes or full verification), so a bad actor’s forged data can be proven on-chain by a dispute mechanism.Orchestrators commit to jobs by staking, and any detected mis-transcoding can trigger an on-chain slashing penalty.Protocol Actors
The Livepeer Protocol defines multiple key actors that participate in the network and perform specific functions.Orchestrators
Orchestrators
OrchestratorsOrchestrators are the main participants in the Livepeer Protocol. They are responsible for processing video and AI jobs, earning fees and rewards, and maintaining the network’s security and decentralization.
Gateways
Gateways
GatewaysGateways are the entry point for applications into the Livepeer network. They are the coordination layer that connects real-time AI and video workloads to the orchestrators who perform the GPU compute.
Delegators
Delegators
DelegatorsDelegators are LPT holders who delegate their tokens to an orchestrator of their choice. They share in the rewards and fees earned by the orchestrator, and also share in any slashing penalties.
