We study efficiency in a proof-of-work blockchain with non-zero latencies, focusing in particular on the (inequality in) individual miners’ efficiencies. Prior work attributed differences in miners’ efficiencies mostly to attacks, but we pursue a different question: Can inequality in miners’ efficiencies be explained by delays, even when all miners are honest? Traditionally, such efficiency-related questions were tackled only at the level of the overall system, and in a peer-to-peer (P2P…

An Economic Analysis of Difficulty Adjustment Algorithms in Proof-of-Work Blockchain Systems
TLDR
It is proved that, when the hash supply is elastic, the Bitcoin DAA fails to stabilize the block arrival rate, and the current Bitcoin system might collapse once a sharp price reduction lowers the mining reward.
Impact of Geo-Distribution and Mining Pools on Blockchains: A Study of Ethereum
TLDR
A detailed, one-month study of the Ethereum network from several geographically dispersed observation points, which identifies previously undocumented forms of selfish behavior and shows that the prevalence of powerful mining pools exacerbates the geographical impact on block propagation delays.
Stochastic Models and Wide-Area Network Measurements for Blockchain Design and Analysis
TLDR
Stochastic network models are developed to capture the Blockchain evolution and dynamics and analyze the impact of the block dissemination delay and hashing power of the member nodes on Blockchain performance in terms of the overall block generation rate and required computational power for launching a successful attack.
VIBES: fast blockchain simulations for large-scale peer-to-peer networks: demo
TLDR
VIBES is proposed: a configurable blockchain simulator for large scale peer-to-peer networks and its ability to simulate blockchain systems beyond bitcoin and its support for large-scale simulations with thousands of nodes.
Blockchain Mining Games
TLDR
Two simplified forms of the stochastic game of miners participating in the bitcoin protocol are considered, in which the miners have complete information and when the computational power of a miner is large, he deviates from the expected behavior, and other Nash equilibria arise.
Under the Hood of the Ethereum Gossip Protocol
TLDR
It is found that a node’s location has a significant impact on when it hears about blocks, and that the precise behavior of this has changed over time (e.g., nodes in the US have become less likely to hear about new blocks first).
On the Security and Performance of Proof of Work Blockchains
TLDR
This paper introduces a novel quantitative framework to analyse the security and performance implications of various consensus and network parameters of PoW blockchains and devise optimal adversarial strategies for double-spending and selfish mining while taking into account real world constraints.
SimBlock: A Blockchain Network Simulator
TLDR
This study developed a blockchain network simulator SimBlock that can easily change behavior of nodes, so that it enables to investigate the influence of nodes' behavior on blockchains and compared some simulation results with the measured values in actual blockchains to demonstrate the validity of this simulator.
Analysis of the Blockchain Protocol in Asynchronous Networks
Nakamoto’s famous blockchain protocol enables achieving consensus in a so-called permissionless setting—anyone can join (or leave) the protocol execution, and the protocol instructions do not depend
