Graph Labeling PoSW

Definition ∞ Graph Labeling Proof of Space-Time (PoST) is a consensus mechanism where participants demonstrate they have allocated a specific amount of storage space over a defined period. This method involves a computational challenge related to labeling nodes within a graph structure, which is then used to verify the allocated storage. It provides a more environmentally sustainable alternative to traditional Proof of Work.
Context ∞ Graph Labeling PoST is a developing area in consensus algorithm research, aiming to offer a secure and resource-efficient method for validating blockchain transactions. Its adoption seeks to address concerns regarding energy consumption associated with Proof of Work systems. Current research focuses on optimizing the graph labeling algorithms to enhance security against various attack vectors and improve network scalability.
