Pricing Security in Proof-of-Work Systems
George Bissias, Rainer Böhme, David Thibodeau +1
A key component of security in decentralized blockchains is proof of opportunity cost among block producers. In the case of proof-of-work (PoW), currently used by the most prominen…
ZipPhone: Protecting user location privacy from cellular service providers
Keen Sung, Brian Levine, Mariya Zheleva
Wireless service providers track the time and location of all user connections. Location inference attacks have been effective in revealing the identity of anonymous users of wirel…
Greedy but Cautious: Conditions for Miner Convergence to Resource Allocation Equilibrium
George Bissias, Brian N. Levine, David Thibodeau
All public blockchains are secured by a proof of opportunity cost among block producers. For example, the security offered by proof-of-work (PoW) systems, like Bitcoin, is due to s…
Bonded Mining: Difficulty Adjustment by Miner Commitment
George Bissias, David Thibodeau, Brian N. Levine
Proof-of-work blockchains must implement a difficulty adjustment algorithm (DAA) in order to maintain a consistent inter-arrival time between blocks. Conventional DAAs are essentia…
Using Economic Risk to Model Miner Hash Rate Allocation in Cryptocurrencies
George Bissias, Brian N. Levine, David Thibodeau
Abrupt changes in the miner hash rate applied to a proof-of-work (PoW) blockchain can adversely affect user experience and security. Because different PoW blockchains often share h…
Bobtail: A Proof-of-Work Target that Minimizes Blockchain Mining Variance (Draft)
George Bissias, Brian Neil Levine
Blockchain systems are designed to produce blocks at a constant average rate. The most popular systems currently employ a Proof of Work (PoW) algorithm as a means of creating these…
