Cross-Channel: Scalable Off-Chain Channels Supporting Fair and Atomic Cross-Chain Operations. (arXiv:2212.07265v1 [cs.CR])

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. Off-chain channels, as a promising blockchain scaling
technique, can enable micro-payment transactions without involving on-chain
transaction settlement. However, existing channel schemes can only be applied
to operations within a single blockchain, failing to support cross-chain
services. Therefore in this paper, we propose Cross-Channel, the first
off-chain channel to support cross-chain services. …
