Block Building Market

The block building market is a competitive environment where specialized entities, known as builders, vie to create the most profitable blocks for a blockchain network. These builders aggregate transaction bundles and fees, paying a portion of their profits to validators for the right to propose the block.

This market structure has emerged to handle the complexity of MEV extraction and to optimize block space utilization. It is a highly dynamic and technical space where participants must constantly innovate to maintain their edge.

The market is influenced by gas prices, network congestion, and the volume of DeFi activity. It represents a shift from a simple mempool-based system to a more sophisticated, tiered architecture.

The block building market is a critical component of modern blockchain protocol physics and economics.
