Known implementations for cross-blockchain token transfer do not provide mechanisms that prevent tokens from getting lost in transit. Ideally, such finalization mechanisms do not rely on a centralized authority in order to avoid undermining the blockchainīs general principle of decentralization.
In this paper, we present extensions for a cross-blockchain token transfer protocol to ensure that tokens in transit are eventually recreated on the destination blockchain and to provide transfer confirmations on both blockchains involved in the transfer in a fully decentralized manner. Further, we evaluate the proposed protocol extensions in terms of transfer cost and duration by transferring ERC20 tokens from Rinkeby to Ropsten.
