eth_newBlockFilter creates a server-side filter that tracks new block arrivals on Base — Coinbase's OP Stack rollup that uses ETH for gas — and returns a hex filter ID. You then poll that ID with eth_getFilterChanges, and each poll hands back the hashes of blocks that have appeared since your last call. Because the Base sequencer seals a block roughly every 2 seconds, polling at a similar cadence keeps you close to the chain head. Create the filter against https://base.therpc.io/YOUR_API_KEY (Base mainnet, chain ID 8453 / 0x2105); the call takes no parameters.
