RLP (Recursive Length Prefix)

Recursive Length Prefix (RLP) is a data encoding method used in blockchain systems like Ethereum to efficiently serialize complex data structures. It encodes data by prefixing each item with its length, allowing easy parsing and reconstruction. When data contains nested structures, RLP applies the same process repeatedly to each layer, hence "recursive." This approach ensures data is stored compactly and can be parsed reliably, facilitating communication and data storage in decentralized networks.
