Parallax creates, stores and transfers large volumes of data. This data must get formatted in standardized and memory-efficient ways to allow anyone to run a node on relatively modest consumer-grade hardware. To achieve this, several specific data structures are used on the Parallax stack.

​
Prerequisites

You should understand the fundamentals of Parallax and client software. Familiarity with the networking layer and the Ethereum whitepaper is recommended.

​
Data structures

​
Patricia merkle tries

Patricia Merkle Tries are structures that encode key-value pairs into a deterministic and cryptographically authenticated trie. These are used extensively across Parallax. More on Patricia Merkle Tries

​
Recursive Length Prefix

Recursive Length Prefix (RLP) is a serialization method used extensively across Parallax. More on RLP
