How to Use Bitcoin to Design Fair Protocols
Iddo Bentov,Ranjit Kumaresan +1 more
TL;DR: In this article, the authors study a model of fairness in secure computation in which an adversarial party that aborts on receiving output is forced to pay a mutually predefined monetary penalty.
Proceedings ArticleDOI
Efficient Batched Oblivious PRF with Applications to Private Set Intersection
TL;DR: In this article, Pinkas et al. describe a lightweight protocol for oblivious evaluation of a pseudorandom function (OPRF) in the presence of semihonest adversaries, which is particularly efficient when used to generate a large batch of OPRF instances.
Proceedings ArticleDOI
How to Use Bitcoin to Incentivize Correct Computations
Ranjit Kumaresan,Iddo Bentov +1 more
TL;DR: An efficient secure computation protocol is shown that monetarily penalizes an adversary that attempts to learn one bit of information but gets detected in the process and captures the amount of computational effort required to validate Bitcoin transactions required to implement it in Bitcoin.

Sprites and State Channels: Payment Networks that Go Faster Than Lightning
TL;DR: In this paper, the authors propose an off-chain payment channel, which enables two mutually distrustful parties to send payments between each other and can be linked together to form a payment network, such that payments between any two parties can be routed through the network along a path that connects them.

Sprites: Payment Channels that Go Faster than Lightning.
TL;DR: A novel construction for payment channels is developed that reduces the worst-case “collateral cost” for offchain payments and relies on a general purpose primitive called a “state channel,” which is of independent interest.
