bitcoin May not be of interest, but I remember being shocked to see that there was actually a Wireshark parser of Bitcoin network traffic even as early as like 2014-15. (See https://bitcoin.stackexchange.com/questions/91938/bitcoin-protocol-and-wireshark ). So: there's the network level traffic in bitcoin (think like the VER, VERACK, TX messages and whatnot that are gossiped between peers), and then there's the RPC-API that a bitcoind node offers, which would be more analogous/a better fit...
