AI translates the explanation and quiz text while preserving code and answer scoring.

Laravel apps interact with blockchains like Ethereum by sending JSON-RPC calls (e.g., eth_getBalance, eth_call) over HTTP to a node provider such as Infura or Alchemy, typically via the Http facade. Requests should include retries, exponential backoff, and timeout handling since node providers can rate-limit or fail transiently. Responses return hex-encoded values that must be decoded (e.g., hexdec or bcmath for large numbers) before use.
