I have a JSON format block (Height:500000) here. As you can see here, it is a segwit block and its actual size is 1048581 and stripped size (without witness data) is 981404. I want to strip full node's segwit fields and convert it to a legacy node using any inbuilt method or an implemented solution. (According to my knowledge, it can't be done by downloading older versions of bitcoin core client and using JSON-RPC requests, because it has an issue of still having fields from segwit upgradation.) OR simply I just wanna deal with blocks data as legacy nodes see it. Can I download block data the way legacy nodes see it in JSON/hex format using any API or JSON-RPC calls?
