eth_newBlockFilter registers a server-side filter that tracks new block arrivals on OP Mainnet and returns a hex filter ID. You then poll that ID with eth_getFilterChanges to receive the hashes of blocks that have been produced since your last poll. OP Mainnet is the ETH-gas OP Stack rollup at chain ID 10 (0xa), and because its single sequencer mints a block roughly every 2 seconds, each poll typically returns a small, steady stream of new block hashes. Create the filter against https://optimism.therpc.io/YOUR_API_KEY.
