A hand-tooled scaling instrument
layer2.quest
Enter the mechanical orrery where rollups, sidechains, and state channels revolve above a frost-silver countryside.
What is Layer 2?
The meadow above the main road
Layer 2 networks carry busy commerce away from the congested base chain, then return concise proofs and settlements like ledgers delivered to a manor archive at dusk.

INHERIT TRUST
Rollup Mechanism
Harvests gathered from scattered fields
Optimistic and zero-knowledge rollups bind many transactions into a single bale. The dial below compresses a field of activity into a proof small enough for the base chain to inspect.

Sidechain Explorer
Railway switches beyond the main line
Sidechains run their own validators and timetables. Throw the lever to see assets routed between independent consensus tracks and the settlement station.
Main bridgeSide relay
State Channels
Rivers of signed intent
Participants exchange signed updates privately, like boats passing sealed notes along a moonlit stream. Only the opening and closing milestones need the public ledger.
The Landscape
Constellations over validator hills
Protocols become fixed stars: each with its own orbit, bridge, sequencer, and proof system, all turning above Ethereum's patient horizon.
