Definition ∞ Block production decentralization measures the distribution of power among entities responsible for creating new blocks on a blockchain. It quantifies how widely spread the block validation or mining capabilities are across various participants. High decentralization suggests that no single group holds undue influence over transaction ordering or network censorship. This characteristic is fundamental to a blockchain’s resilience and censorship resistance.
Context ∞ The state of block production decentralization is a continuous subject of analysis within blockchain ecosystems, particularly for proof-of-stake and proof-of-work networks. Debates often address concerns about validator centralization in PoS systems or mining pool dominance in PoW chains. Efforts to enhance decentralization often involve protocol adjustments, such as improved random selection mechanisms or economic incentives for smaller participants, to uphold network security and integrity.
