The signer can be recovered by taking a block, constructoring the headers and then using the Ecrecover of the go-ethereum crypto library.

First, we’ll download a block, extract the result using jq and then save the response in block.json.

curl -s -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0", "id": 1, "method": "eth_getBlockByNumber", "params": ["0x31b7feb", true]}' https://polygon-rpc.com | jq '.result' | tee block.json
