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…
Detection of Local Mixing in Time-Series Data Using Permutation Entropy
Michael Neuder, Elizabeth Bradley, Edward Dlugokencky +2
While it is tempting in experimental practice to seek as high a data rate as possible, oversampling can become an issue if one takes measurements too densely. These effects can tak…
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…
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…
Anomaly Detection in Paleoclimate Records using Permutation Entropy
Joshua Garland, Tyler R. Jones, Michael Neuder +3
Permutation entropy techniques can be useful in identifying anomalies in paleoclimate data records, including noise, outliers, and post-processing issues. We demonstrate this using…
Climate entropy production recorded in a deep Antarctic ice core
Joshua Garland, Tyler R. Jones, Elizabeth Bradley +2
Paleoclimate records are extremely rich sources of information about the past history of the Earth system. Information theory, the branch of mathematics capable of quantifying the…
