"Deterministic Witnesses for Claim-First Transactions";
Report for White Paper for PANTOS;
Technologies enabling interoperability across blockchains have recently gained much popularity in science and industry. Cross-blockchain asset transfers are one particular use case which has been proposed to foster such interoperability. In previous work, we have presented the concept of claim-first transactions as a method of transferring assets from one blockchain to another in a decentralized way. In this white paper, we address existing challenges of this concept. We present a way of creating cryptographic Proof of Intent for cross-blockchain asset transfers, and propose the concept of deterministic witnesses, a solution for assigning witness rewards in claim-first transactions. This work supports the implementation of cross-blockchain asset transfers using claim-first transactions by providing concrete algorithms.
