"Towards Efficient Cross-Blockchain Token Transfers";
Report for White Paper for PANTOS;
Interoperability between blockchains remains an open problem, with current interoperability approaches providing very limited means of cross-blockchain interaction, mostly in the form of atomic swaps. More general means of blockchain interoperability such as cross-blockchain data exchange, including cross-blockchain token transfer would contribute to dissolving today´s fragmentation of the research and development field of blockchains. To address this issue, within the TAST research project, a cross-blockchain token was developed. However, the developed solution suffers from high synchronization cost.
In this paper, we discuss requirements for more efficient crossblockchain token transfers, describe open research challenges,
and give an outlook on two approaches aiming to overcome these
