Cross-Channel: Scalable Off-Chain Channels Supporting Fair and Atomic Cross-Chain Operations [PDF]
Cross-chain technology facilitates the interoperability among isolated blockchains on which users can freely communicate and transfer values. Existing cross-chain protocols suffer from the scalability problem when processing on-chain transactions.

Interoperability and Cross-Chain Security
The Blockchain protocol has become an essential technology capable of providing decentralization solutions for numerous industries. At the core of its progress, the idea of resembling Blockchains through a concept is known as integration. This review focuses on the underlying concept, technology development, and security issues in the interconnectivity

Cross-Chain State Machine Replication
This paper considers the classical state machine replication (SMR) problem in a distributed system model inspired by cross-chain exchanges. We propose a novel SMR protocol adapted for this model. Each state machine transition takes $O(n)$ message delays, where $n$ is the number of active participants, of which any number may be Byzantine. This protocol

Distributed Runtime Verification of Metric Temporal Properties for Cross-Chain Protocols [PDF]
Transactions involving multiple blockchains are implemented by cross-chain protocols. These protocols are based on smart contracts, programs that run on blockchains, executed by a network of computers. Verifying the runtime correctness of smart contracts

Game Theoretical Analysis of Cross-Chain Swaps [PDF]
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 or Ethers). We present a mathematical framework allowing to characterize blockchain swap protocols as the combination of a publishing and a commitment ...
