user117463: What serialization format is used in bitcoin network? I know in Ethereum, there is the  RLP which has been replaced with SSZ. Polkadot has it's own serialization format called SCALE, but I have not been able to find information on what serialization format is used in Bitcoin.

user129640: Bitcoin uses different serialization formats for different data structures, as described on https://en.bitcoin.it/wiki/Protocol_documentation.
