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 … WebMar 26, 2024 · Greedy Heaviest-Observed Sub-Tree This consensus rule relies on the size of subtrees rooted at blocks along the longest, main blockchain. Here, size is similarly defined as aggregate proof of work.
