"Cross-Blockchain Technologies: Review, State of the Art, and Outlook";
Report for White Paper for PANTOS;
Interoperability between blockchains remains an open problem, with current approaches providing very limited means of cross-blockchain interaction, mostly in the form of atomic swaps. However, very little means of cross-blockchain data exchange, including cross-blockchain token transfers, are found in literature. To address this issue, within the TAST research project, we aim to create a platform for enabling cross-blockchain interoperability, in order to counter the fragmentation of the research and development field of blockchains. In this paper, we review the current state of the art in the field of cross-blockchain technologies, including our own work within the TAST research project, answer former open questions from today's perspective, and give an outlook of current challenges and possible future work.
