Value Extraction

Definition ∞ Value extraction describes processes or mechanisms within a system designed to capture and transfer economic worth from one party to another. In decentralized systems, this can occur through transaction fees, protocol incentives, or sometimes through mechanisms that disproportionately benefit certain participants over others. It relates to how economic utility is distributed or appropriated.
Context ∞ Discussions about value extraction are pertinent when examining the tokenomics of new projects, the fee structures of decentralized exchanges, or the economic incentives governing blockchain protocols. Reports on this topic often analyze whether the distribution of value is equitable and sustainable for the long-term health and growth of the ecosystem.
