WebThe Greedy Heaviest Observed SubTree (GHOST) rule says that, starting at the genesis block, each fork is resolved by choosing the heaviest branch that has the most blocks built on it. In this diagram, the heaviest chain is the fork that has accumulated most blocks built on top of it. If you are using the GHOST rule for chain selection, this ... 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.
