Serialization is the process of encoding and converting data structures into byte sequences. Serialization can be thought of as translating data into a format that a standard computer system can understand using a common set of rules. The data can be translated back to Its original format using these same rules. The Ethereum blockchain uses an encoding and decoding algorithm called Recursive Length Prefix (RLP) to serialize it’s blockchain data.
