Short Paper: Accountable Safety Implies Finality
Joachim Neu, Ertem Nusret Tas, David Tse
Motivated by proof-of-stake (PoS) blockchains such as Ethereum, two key desiderata have recently been studied for Byzantine-fault tolerant (BFT) state-machine replication (SMR) con…

Nakamoto Consensus under Bounded Processing Capacity
Lucianna Kiffer, Joachim Neu, Srivatsan Sridhar +2
For Nakamoto's longest-chain consensus protocol, whose proof-of-work (PoW) and proof-of-stake (PoS) variants power major blockchains such as Bitcoin and Cardano, we revisit the cla…
