// monitoring station — L2 scaling reports
Raw, unadorned reporting on optimistic rollups, ZK proofs, and the settlement layer.
Concrete bunker for blockchain data — no marketing, no roadmaps, only signal.

The BOLD upgrade went live without ceremony. We measured challenge-window latency across 412 blocks and found a 38% reduction in worst-case finality. The real story is not the math — it is the social layer.
Brief stall in batch submission. Operators report nominal recovery. We log it because pattern recognition matters.
A walkthrough of pessimistic proofs and the unified bridge. Diagram-heavy. Charts at the bottom.

EIP-4844 is no longer the new thing. We pulled three months of blob inclusion data and compared median fees against pre-blob calldata. The compression is real. The savings are uneven.
A directory of active data-availability committees and their public keys. Nothing speculative.
User-operations, internal calls, batched intents — not all txs are equal. We document our reconciliation rules openly. Disagreements welcome.
Most rollups still run a single sequencer. Some publish a "shared sequencer" roadmap. We mapped the actual operators on-chain and found the failure modes nobody talks about.
// 7 of 12 rollups: 1 sequencer // 3 of 12 rollups: 2-3 sequencers // 2 of 12 rollups: shared (active)
Numbers, no commentary. Reader makes the call.
Not a marketing piece. Walks through interactive vs. non-interactive challenges, with worked examples and the dispute paths that actually run on chain.

For two months we collected every published fee receipt from the seven largest L2s, normalized them against L1 settlement costs, and broke the spread into three components: data-availability cost, proof-generation cost, and operator margin. The result is the chart on the right.
The honest answer is that operator margin varies by an order of magnitude, and the public discourse has not caught up to the data. There is no scandal here — running a rollup is expensive — but the framing matters when you decide where to bridge.
"The cheapest L2 today is not the L2 with the cheapest fees. It is the one whose operator publishes its costs."
