Webat each fork in the chain the heaviest subtree rooted at the fork. This proto-col modi cation alleviates the above-mentioned security problem, and will help block-chain-based protocols grow further. A variant of GHOST has been adopted and implemented by the Ethereum … Web(“greedy heaviest-observed subtree”) fork choice rule [21] with the Casper consensus protocol [4]. They prove liveness of the protocol both probabilistically and practically in the face of an adversary with less than one-third of the staking power (a constraint that is not imposed on the Tezos protocol), and minimize deep reorgs by
WebIn Ethereum, the issue of high orphaned blocks resulting from smaller times between blocks is mitigated by using the Greedy Heaviest Observed Subtree (GHOST) protocol whereby orphaned blocks (uncles) are also included in determining the valid chain. WebNov 12, 2024 · Orphan and stale blocks are expected to be encountered more often than in Bitcoin so miners should waste more time on them. Luckily, it is different thanks to GHOST protocol (Greedy Heaviest Observed Subtree) implemented by Ethereum developers. The concept of GHOST is simple. Miners that find orphan and stale blocks get rewarded, but …
