Title: Stochastic models for blockchain analysis

Abstract: A blockchain is a distributed ledger maintained by achieving consensus in a P2P network. This talk focuses on the security of Proof-of-Work blockchains, more specifically on an attack called double spending. We first introduce some blockchain concepts along with a description of the Proof-of-Work protocol before setting up a mathematical model to compute the likelihood of a successful double spending attack.

This talk is based on the following paper: https://www.cambridge.org/core/journals/advances-in-applied-probability/article/abs/fraud-risk-assessment-within-blockchain-transactions/DC96574C5098794A8345167F69149A44
