Low-cost attacks on Ethereum 2.0 by sub-1/3 stakeholders
Michael Neuder, Daniel J. Moroz, Rithvik Rao +1
We outline two dishonest strategies that can be cheaply executed on the Ethereum 2.0 beacon chain, even by validators holding less than one-third of the total stake: malicious chai…
Defending Against Malicious Reorgs in Tezos Proof-of-Stake
Michael Neuder, Daniel J. Moroz, Rithvik Rao +1
Blockchains are intended to be immutable, so an attacker who is able to delete transactions through a chain reorganization (a malicious reorg) can perform a profitable double-spend…
Double-Spend Counterattacks: Threat of Retaliation in Proof-of-Work Systems
Daniel J. Moroz, Daniel J. Aronoff, Neha Narula +1
Proof-of-Work mining is intended to provide blockchains with robustness against double-spend attacks. However, an economic analysis that follows from Budish (2018), which considers…
Selfish Behavior in the Tezos Proof-of-Stake Protocol
Michael Neuder, Daniel J. Moroz, Rithvik Rao +1
Proof-of-Stake consensus protocols give rise to complex modeling challenges. We analyze the recently-updated Tezos Proof-of-Stake protocol and demonstrate that, under certain condi…
