Parties lock funds in an on-chain multisig, then exchange signed state updates off-chain (payments, game moves). Each update is a pending commitment; either party can close the channel by submitting the latest signed state on-chain. Dispute

1. What Is a State Channel
A state channel is a layer-2 technique where two parties transact off-chain, updating a shared state, and only the opening and closing states are settled on-chain — enabling fast, cheap, high-frequency interactions.
2. How It Works
Parties lock funds in an on-chain multisig, then exchange signed state updates off-chain (payments, game moves). Each update is a pending commitment; either party can close the channel by submitting the latest signed state on-chain. Disputes are resolved via challenge periods. Lightning Network generalizes channels into a payment network.
3. Why It Matters
State channels demonstrate off-chain scaling — near-zero fees, instant finality between parties. They suit recurring interactions (payments, gaming, microtransactions). Their limitations (liquidity lockup, online counterparties, channel lifecycle complexity) limited adoption compared to rollups.
4. Key Facts
- Only open/close transactions hit the base chain
- Challenge periods protect against stale-state claims
- Lightning Network is the most successful channel network
- Channels require both parties to be online periodically
