eth_newBlockFilter creates a server-side filter that watches for new block arrivals and returns a hex filter ID. You then poll that ID with eth_getFilterChanges to receive the hashes of blocks added since your last poll. On Polygon — the MATIC-fueled PoS chain at https://polygon.therpc.io/YOUR_API_KEY (chain ID 137, 0x89) — blocks are produced roughly every two seconds, so a steady polling loop is a lightweight way to keep an HTTP client in step with the chain head without holding a WebSocket connection open.
