Payment Networks as Creation Games
Georgia Avarikioti, Rolf Scheuner, Roger Wattenhofer
Payment networks were introduced to address the limitation on the transaction throughput of popular blockchains. To open a payment channel one has to publish a transaction on-chain…
Online Payment Network Design
Georgia Avarikioti, Kenan Besic, Yuyi Wang +1
Payment channels allow transactions between participants of the blockchain to be executed securely off-chain, and thus provide a promising solution for the scalability problem of p…
Bitcoin Security under Temporary Dishonest Majority
Georgia Avarikioti, Lukas Kaeppeli, Yuyi Wang +1
We prove Bitcoin is secure under temporary dishonest majority. We assume the adversary can corrupt a specific fraction of parties and also introduce crash failures, i.e., some hone…
Brick: Asynchronous Payment Channels
Georgia Avarikioti, Eleftherios Kokoris Kogias, Roger Wattenhofer +1
Off-chain protocols (channels) are a promising solution to the scalability and privacy challenges of blockchain payments. Current proposals, however, require synchrony assumptions…
Towards Secure and Efficient Payment Channels
Georgia Avarikioti, Felix Laufenberg, Jakub Sliwinski +2
Micropayment channels are the most prominent solution to the limitation on transaction throughput in current blockchain systems. However, in practice channels are risky because par…
Structure and Content of the Visible Darknet
Georgia Avarikioti, Roman Brunner, Aggelos Kiayias +2
In this paper, we analyze the topology and the content found on the "darknet", the set of websites accessible via Tor. We created a darknet spider and crawled the darknet starting…
High Dimensional Clustering with -nets
Georgia Avarikioti, Alain Ryser, Yuyi Wang +1
Clustering, a fundamental task in data science and machine learning, groups a set of objects in such a way that objects in the same cluster are closer to each other than to those i…
Algorithmic Blockchain Channel Design
Georgia Avarikioti, Yuyi Wang, Roger Wattenhofer
Payment networks, also known as channels, are a most promising solution to the throughput problem of cryptocurrencies. In this paper we study the design of capital-efficient paymen…
Payment Network Design with Fees
Georgia Avarikioti, Gerrit Janssen, Yuyi Wang +1
Payment channels are the most prominent solution to the blockchain scalability problem. We introduce the problem of network design with fees for payment channels from the perspecti…
Practical linear-space Approximate Near Neighbors in high dimension
Georgia Avarikioti, Ioannis Z. Emiris, Ioannis Psarros +1
The -approximate Near Neighbor problem in high dimensional spaces has been mainly addressed by Locality Sensitive Hashing (LSH), which offers polynomial dependence on the dimens…
