Speculative Denial-of-Service Attacks in Ethereum
- shmoneforeight 3y agoThe paper presents three attacks against geth-based clients: - ConditionalExhaust is a cheap DoS attack that can prevent a node from including transactions in its blocks - MemPurge is a mempool DoS attack that fills a victim's mempool with transactions that do not pay anything - GhostTX exploits inconsistencies in transaction validation, to create transactions that compel searchers & builders to include them in bundles & blocks even when this goes against their censorship policy
