Layer-2
Layer-2 is a category in The Crypto News Hub with no existing description or market data. The recorded newsroom coverage focuses on Robinhood Chain. On 2026-09-04, Robinhood Chain kept blocks flowing but its blobs stopped reaching Ethereum for 14 minutes, exposing single-sequencer vulnerability under high load. The recorded timeline shows that on 2026-09-05, a major outage and corporate backlash hit Robinhood Chain at its growth peak. The evidence indicates risks in single-sequencer designs and leaves open questions about operational continuity and scalability. No relationships or market snapshots are inferred.
