Invited Paper: Failure is (literally) an Option: Atomic Commitment vs Optionality in Decentralized Finance [article]

Daniel Engel and Maurice Herlihy and Yingjie Xue
2021 arXiv   pre-print
A fault-tolerant protocol is one that ensures that the party offering the option cannot renege, and the party purchasing the option provides fair compensation (in the form of a fee) to the offering party  ...  A fault-tolerant protocol is one that responds to such failures by rolling the system back to an earlier consistent state.  ...  These protocols include Han et al. [9] , Eizinger et al. [7] , Liu [16] , the Komodo platform [19] , Eizinger et al. [7] , and the Arwen protocols [10] . Xu et al.  ...

XChange: A Universal Mechanism for Asset Exchange between Permissioned Blockchains

Martijn de Vos, Can Umut Ileri, Johan Pouwelse
2021 World wide web (Bussum)  
We first present a four-phased protocol that coordinates an asset exchange between two traders.  ...  Our mechanism records the specifications and progression of each trade within records on a distributed log.  ...  The Arwen trading protocol is another protocol to securely trade cryptocurrencies through a centralized exchange without giving up ownership of the assets to the exchange [24] .  ...

2006 IEEE Communications Magazine  
The experiments were carried out by streaming a video file between arwen and quickbeam while "arwen" was moving, following a predetermined track.  ...  Each rate corresponds to a different modulation scheme with its own trade-off between data throughput and distance between the stations.  ...

A Game-Theoretic Analysis of Cross-Chain Atomic Swaps with HTLCs [article]

Jiahua Xu and Damien Ackerer and Alevtina Dubovitskaya
2021 arXiv   pre-print
Nonetheless, as an undesired outcome, reoccurring transaction failures prompt a critical and analytical examination of the protocol.  ...  We study the success rate of the transaction as a function of the exchange rate of the swap, the token price and its volatility, among other variables.  ...  Two important conclusions are therefore that cross-ledger atomic swap trustless protocols could benefit from the use of disciplinary mechanisms, such as collateral deposit, and that allowing agents to  ...

Cross-chain Deals and Adversarial Commerce [article]

Maurice Herlihy and Barbara Liskov and Liuba Shrira
2019 arXiv   pre-print
One protocol, based on synchronous communication, is fully decentralized, while the other, based on semi-synchronous communication, requires a globally shared ledger.  ...  Deals are inspired by classical atomic transactions, but are necessarily different, in important ways, to accommodate the decentralized and untrusting nature of the exchange.  ...  Arwen [26] supports multiple off-chain atomic swaps between parties and exchanges, but their protocol is specialized to currency trading and does not seem to support non-fungible assets.  ...

Moving towards shareable metadata

Sarah L. Shreeves, Jenn Riley, Liz Milewicz
2006 First Monday  
A focus of digital libraries, particularly since the advent of the Open Archives Initiative Protocol for Metadata Harvesting, is aggregating from multiple collections metadata describing digital content  ...  However, the quality and interoperability of the metadata often prevents such aggregations from offering much more than very simple search and discovery services.  ...  We would also like to acknowledge the support of the Digital Library Federation and the work of everyone who has contributed to the Best Practices for  ...

Game Theoretical Analysis of Cross-Chain Swaps

Marianna Belotti, Stefano Moretti, Maria Potop-Butucaru, Stefano Secci
2020 2020 IEEE 40th International Conference on Distributed Computing Systems (ICDCS)  
In this paper we address the distributed cross-chain swap problem in the blockchain context where multiple agents exchange assets across multiple blockchain systems (e.g. trading Bitcoins for Litecoins  ...  Furthermore, we prove that for protocols with a sequential publishing and commitment of the assets transfers, following the prescribed protocol is a sub-game perfect equilibrium.  ...  According to Arwen protocol [27] crypto-assets are swapped through centralized exchange services that in no way acquire the assets custody.  ...
