Node Tracker

Robinhood Chain is an Arbitrum-stack L2 (chain ID 4663) secured by a single sequencer that orders and batches transactions to Ethereum L1. Because ordering is centralized and deterministic, there is no peer-to-peer validator set to enumerate — the network's liveness is the sequencer plus the L1 batch pipeline.

Traditional node trackers map a network's validator/peer topology. On a single-sequencer rollup that concept doesn't apply — decentralization comes from the ability to force-include transactions via L1 and to reconstruct L2 state from the L1 batch data, both surfaced under L1 Batches and Cross-Chain Transactions.
