Deep Dive

The Sequencer Decentralization Problem Nobody Wants to Talk About

Every major Layer 2 still runs a single sequencer. We dig into the technical, economic, and political reasons why decentralized sequencing remains the elephant in every rollup room, and what credible paths forward actually look like.

Blob Markets Are Coming. Here's What That Means for L2 Economics.

As blob utilization pushes toward capacity, the economics of data availability are about to shift fundamentally. We model three scenarios for blob pricing and their downstream effects on every major rollup's fee structure.

What even is this?

layer2.report is an independent publication covering Ethereum's Layer 2 ecosystem. We believe scaling reports shouldn't read like SEC filings. We track rollups, analyze data availability markets, benchmark proof systems, and explain it all like we're telling a friend about something genuinely exciting.

No sponsored content. No token shilling. No jargon walls. Just clear, honest reporting on the infrastructure that's actually scaling Ethereum.
