Block-Building Paradigm

Definition

A Block-Building Paradigm defines the operational model and roles involved in compiling and proposing new blocks for addition to a blockchain. This concept encompasses the processes by which transactions are selected from the mempool, ordered, and then assembled into a valid block structure by network participants. It specifies who performs these tasks, whether a single entity or multiple, and how incentives are structured around this activity. The chosen paradigm directly influences network decentralization, censorship resistance, and the distribution of value extracted from transaction ordering.
