Two Attacks On Proof-of-Stake GHOST/Ethereum
Joachim Neu, Ertem Nusret Tas, David Tse
We present two attacks targeting the Proof-of-Stake (PoS) Ethereum consensus protocol. The first attack suggests a fundamental conceptual incompatibility between PoS and the Greedy…
Three Attacks on Proof-of-Stake Ethereum
Caspar Schwarz-Schilling, Joachim Neu, Barnabé Monnot +3
Recently, two attacks were presented against Proof-of-Stake (PoS) Ethereum: one where short-range reorganizations of the underlying consensus chain are used to increase individual…
Snap-and-Chat Protocols: System Aspects
Joachim Neu, Ertem Nusret Tas, David Tse
The availability-finality dilemma says that blockchain protocols cannot be both available under dynamic participation and safe under network partition. Snap-and-chat protocols have…
Ebb-and-Flow Protocols: A Resolution of the Availability-Finality Dilemma
Joachim Neu, Ertem Nusret Tas, David Tse
The CAP theorem says that no blockchain can be live under dynamic participation and safe under temporary network partitions. To resolve this availability-finality dilemma, we formu…
Successive Cancellation Inactivation Decoding for Modified Reed-Muller and eBCH Codes
Mustafa Cemil Coşkun, Joachim Neu, Henry D. Pfister
A successive cancellation (SC) decoder with inactivations is proposed as an efficient implementation of SC list (SCL) decoding over the binary erasure channel. The proposed decoder…
Ternary Quantized Polar Code Decoders: Analysis and Design
Joachim Neu, Mustafa Cemil Coşkun, Gianluigi Liva
The performance of short polar codes under successive cancellation (SC) and SC list (SCL) decoding is analyzed for the case where the decoder messages are coarsely quantized. This…
