WebApr 7, 2024 · LMD-GHOST stands for "latest message-driven greedy heaviest observed sub-tree". This is a jargon-heavy way to define an algorithm that selects the fork with the greatest accumulated weight of attestations as the canonical one (greedy heaviest subtree) and that if multiple messages are received from a validator, only the latest one … WebIn the same period, Sompolinsky et al [24] introduce GHOST (Greedy Heaviest-Observed Sub-Tree), which uses another way to select the branch. However, they only analysis the behavior of GHOST under some attack cases. Later, Kiayias et al [10] provide a security analysis for GHOST in a low block generation rate under a synchronized network model.
