The onslaught whitethorn unit the Monero assemblage to marque hard decisions. One projected solution involves utilizing DNS checkpoints, trusted snapshots of the blockchain, to counteract aboriginal reorganizations.
Critics reason this would compromise the network’s decentralization. On GitHub, crypto researcher Rucknium pointed retired that the impermanent rollout of DNS checkpoints is highly apt to soon beryllium deployed.
