Hawk: The Blockchain Model of Cryptography and Privacy-Preserving Smart Contracts

A. Kosba, A. Miller, E. Shi, Zikai Wen, Charalampos Papamanthou
Computer Science
IEEE Symposium on Security and Privacy (SP)
22 May 2016

We present Hawk, a decentralized smart contract system that does not store financial transactions in the clear on the blockchain, thus retaining transactional privacy from the public's view. Expand

SoK: Research Perspectives and Challenges for Bitcoin and Cryptocurrencies

J. Bonneau, A. Miller, J. Clark, A. Narayanan, Joshua A. Kroll, E. Felten
Computer Science
IEEE Symposium on Security and Privacy
17 May 2015

We provide the first systematic exposition Bit coin and the many related crypto currencies or 'altcoins.' Drawing from a scattered body of knowledge, we identify three key components of Bit coin's design that can be decoupled. Expand

The Honey Badger of BFT Protocols

Bitcoin and Cryptocurrency Technologies provides a comprehensive introduction to the revolutionary yet often misunderstood new technologies of digital currency. Expand

On Scaling Decentralized Blockchains - (A Position Paper)

Kyle Croman, C. Decker, +9 authors Roger Wattenhofer
Computer Science
Financial Cryptography Workshops
22 February 2016

We analyze how fundamental and circumstantial bottlenecks in Bitcoin limit the ability of its current peer-to-peer overlay network to support substantially higher throughputs and lower latencies. Expand

Stubborn Mining: Generalizing Selfish Mining and Combining with an Eclipse Attack

Kartik Nayak, Srijan Kumar, A. Miller, E. Shi
Computer Science
IEEE European Symposium on Security and Privacy…
21 March 2016

We expand the mining strategy space to include novel "stubborn" strategies that, for a large range of parameters, earn the miner more revenue. Expand

J. Bonneau, A. Narayanan, A. Miller, J. Clark, Joshua A. Kroll, E. Felten
Business, Computer Science
Financial Cryptography
3 March 2014

We propose Mixcoin, a protocol to facilitate anonymous payments in Bitcoin and similar cryptocurrencies. Expand

Step by Step Towards Creating a Safe Smart Contract: Lessons and Insights from a Cryptocurrency Lab

Computer Science
Financial Cryptography Workshops
22 February 2016

We document our experiences in teaching smart contract programming to undergraduate students at the University of Maryland, the first pedagogical attempt of its kind. Expand

Permacoin: Repurposing Bitcoin Work for Data Preservation

A. Miller, A. Juels, E. Shi, Bryan Parno, Jonathan Katz
Computer Science
IEEE Symposium on Security and Privacy
18 May 2014

We propose a modification to Bit coin that repurposes its mining resources to achieve a more broadly useful goal: distributed storage of archival data. Expand

Sprites: Payment Channels that Go Faster than Lightning

A. Miller, I. Bentov, R. Kumaresan, Patrick McCorry
Computer Science
ArXiv
19 February 2017

We develop a novel construction for payment channels that reduces the worst-case “collateral cost” for offchain payments. Expand
