A ghost blockchain refers to a concept in blockchain technology that involves the GHOST protocol, which stands for Greedy Heaviest Observed Subtree. This protocol was designed to improve block confirmation speed and network security in blockchain networks, initially proposed to address specific issues in the 
Bitcoin network but later adopted and modified by other blockchain technologies like Ethereum. It considers not only the longest chain but also the “heaviest” chain, incorporating information from orphan blocks to optimize network performance and security.
