Conversation
Add a new `tempo p2p-proxy` subcommand that runs a proxy P2P node serving cached block data fetched from an RPC endpoint. Features: - Caches up to 1 day of blocks (172,800 at 500ms block time) - Serves GetBlockHeaders and GetBlockBodies requests with RPC fallback - Supports HTTP and WebSocket RPC transports via connect() - Configurable max inbound peers (default 100), listen port, discovery port - Periodic stats logging (peer count, headers/bodies served) - Empty responses for GetPooledTransactions, receipts, and other requests - Inbound-only connections (zero outbound) - Always responds to peers even on internal failures Amp-Thread-ID: https://ampcode.com/threads/T-019c7645-fde2-734e-bfd8-30028c50faf9 Co-authored-by: Amp <amp@ampcode.com>
