WebJun 22, 2024 · To some extent, Casper is the son of GHOST, or Greedy Heaviest Observed Subtree. Introduced to the Ethereum ecosystem in 2013, the protocol combats centralization. Fast blockchain networks create stale blocks, also known as orphan blocks; Ethereum refers to them as “uncles” to distinguish them from parent and child blocks.
