Mean Field Analysis of Blockchain Systems
Yanni Georghiades, Takashi Tanaka, Sriram Vishwanath
We present a novel framework for analyzing blockchain consensus mechanisms by modeling blockchain growth as a Partially Observable Stochastic Game (POSG) which we reduce to a set o…
Majority is Not Required: A Rational Analysis of the Private Double-Spend Attack from a Sub-Majority Adversary
Yanni Georghiades, Rajesh Mishra, Karl Kreder +1
We study the incentives behind double-spend attacks on Nakamoto-style Proof-of-Work cryptocurrencies. In these systems, miners are allowed to choose which transactions to reference…
Achieving Almost All Blockchain Functionalities with Polylogarithmic Storage
Parikshit Hegde, Robert Streit, Yanni Georghiades +2
In current blockchain systems, full nodes that perform all of the available functionalities need to store the entire blockchain. In addition to the blockchain, full nodes also stor…
Scalable Multi-Chain Coordination via the Hierarchical Longest Chain Rule
Yanni Georghiades, Karl Kreder, Jonathan Downing +2
This paper introduces BlockReduce, a Proof-of-Work (PoW) based blockchain system which achieves high transaction throughput through a hierarchy of merged mined blockchains, each op…
Who Needs Consensus? A Distributed Monetary System Between Rational Agents via Hearsay
Yanni Georghiades, Robert Streit, Vijay Garg
We propose a novel distributed monetary system called Hearsay that tolerates both Byzantine and rational behavior without the need for agents to reach consensus on executed transac…
HashCore: Proof-of-Work Functions for General Purpose Processors
Yanni Georghiades, Steven Flolid, Sriram Vishwanath
Over the past five years, the rewards associated with mining Proof-of-Work blockchains have increased substantially. As a result, miners are heavily incentivized to design and util…
