TLDR
We introduce a 2-dimensional Markov process to model the behavior of a selfish mining strategy inspired by a Bitcoin mining strategy proposed by Eyal and Sirer. Expand

Analysis of Nakamoto Consensus, Revisited
TLDR
In the Bitcoin white paper[1], Nakamoto proposed a very simple Byzantine fault tolerant consensus algorithm that is also known as Nakamoto consensus. Expand

Eunomia: A Permissionless Parallel Chain Protocol Based on Logical Clock
TLDR
We propose Eunomia, which leverages logical clock and fine-grained UTXO sharding to realize a simple, efficient, secure and permissionless parallel chain protocol. Expand

A fully-distributed directional-to-directional MAC protocol for mobile ad hoc networks
TLDR
We propose a new fully-distributed directional-to-directional MAC protocol for mobile ad hoc networks (MANETs) where all nodes operate in the directional-only mode. Expand

Design and experimental evaluation of long-distance and high-mobility ZigBee transceivers for WSNs
TLDR
We propose a simple and robust ZigBee transceiver design that supports the transmission distance of 1.2km and moving speed of 60km/h. Expand

Fast-HotStuff: A Fast and Resilient HotStuff Protocol
TLDR
The HotStuff protocol is a recent breakthrough inByzantine Fault Tolerant (BFT) consensus that enjoys responsiveness and linear view change. Expand

Incentive Analysis of Bitcoin-NG, Revisited
TLDR
Bitcoin-NG is among the first blockchain protocols to approach the near-optimal throughput by decoupling blockchain operation into two planes: leader election and transaction serialization. Expand

A Secure Consensus Protocol for Sidechains
TLDR
We introduce Cumulus, a low overhead, highly efficient, security provable sidechain protocol for scale-out throughput without sacrificing security. Expand

Leaderless Byzantine Fault Tolerant Consensus
TLDR
We propose a leaderless BFT consensus protocol, in which nodes simply compete to propose blocks (containing a batch of clients' requests) without the need of explicit coordination. Expand
The Hermes BFT for Blockchains
TLDR
We show that in Hermes equivocating by a Byzantine primary is unlikely, expensive and ineffective. Expand
