Running following command I get the response as follows: Command: curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_protocolVersion","params":[],"id":67}' 3.32.29.150:8545 Response: {"jsonrpc":"2.0","id":67,"result":"0x3f"}

As per the response the protocol version is "0x3f", my question where it is defined inside the go-ethereum code?

Ethereum is a protocol that is based on the The RLPx Transport Protocol protocol. Every time we have a change in the Ethereum protocol, we have to update the protocol version. For more info about all the protocol versions in Ethereum please refer to this official protocol change log:
