Robinhood Chain Continues Block Production During Outage, but Data Reaches Ethereum for Only 14 Minutes

During a recent outage reported on Friday, Robinhood Chain kept producing blocks without interruption. However, the chain's transaction data was only transmitted to Ethereum for a total of 14 minutes, occurring across two distinct gaps. The first gap saw no data reach Ethereum, while the second was attributed by Arbitrum to issues with Ethereum's blob market, which aligns with the second data gap. This disruption affected the visibility and verifiability of Robinhood Chain's transaction history on Ethereum, which is crucial for reconstructing the chain and verifying funds. The incident highlights potential vulnerabilities in cross-chain data propagation and the reliance on Ethereum's blob market infrastructure for data availability.
