The Strata Codex

layer-2.wiki

An illuminated field guide to the invisible strata where rollups compress transactions, inherit security, and settle back into bedrock consensus.

01 / Bedrock Consensus

Layer 1 is the load-bearing stone.

Ethereum finalizes the canonical history beneath every rollup shelf. Layer 2 systems move faster above it, but their roots anchor into this darker consensus seam.

02 / Compression Vein

Receipts become sediment.

Batches squeeze many off-chain transactions into a narrow calldata ribbon. The rollup publishes enough evidence for reconstruction without carrying every movement at full surface weight.

03 / Sequencer Gallery

A brass metronome orders the shelf.

The sequencer proposes an immediate local ordering, giving users quick inclusion while the deeper archive waits for posted data and settlement proofs.

04 / Proof Lantern

Verification lights the cavern.

Validity proofs glow when computation is compressed into a small witness. Fraud proofs keep a lantern unlit until a challenge window exposes an invalid transition.

05 / Bridge Fault

Messages cross a mineral fracture.

Bridges carry assets and instructions between strata. The fault is useful, but every crossing depends on the verification rules and exit delays carved around it.

06 / Data Availability Reef

Fragments must remain retrievable.

A rollup is reconstructable only when its posted data can be found. The reef is built from small square samples: enough distributed pieces to rebuild the state transition.

07 / Finality Archive

The archive closes with a pale green ring.

When data, ordering, proof, and settlement align, the Layer 2 leaf is cataloged into the deeper record. The fast shelf becomes part of the permanent geological library.
