The Strata Codex
An illuminated field guide to the invisible strata where rollups compress transactions, inherit security, and settle back into bedrock consensus.
01 / Bedrock Consensus
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
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.
batch[2048] → calldata ribbon → root:0x84f7c5
03 / Sequencer Gallery
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
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
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
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
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.
