Block Reward Dependency

Definition ∞ Block Reward Dependency describes the extent to which cryptocurrency miners rely on newly issued coins, known as block rewards, for their operational revenue. This reliance is a fundamental aspect of proof-of-work blockchain protocols, incentivizing participants to secure the network. As block rewards decrease over time through events like halving, transaction fees are expected to compensate for the reduction in miner income. The degree of this dependency influences mining profitability and network security over the long term.
Context ∞ The ongoing discussion surrounding Block Reward Dependency centers on the sustainability of mining as block subsidies diminish, particularly after halving events. Analysts are closely watching how transaction fees will compensate for reduced block rewards to ensure continued network security. This shift necessitates adaptive strategies for mining operations and could alter the competitive landscape within the mining sector.
