Abstract: The scalability and interoperability of traditional blockchain can hardly meet the value delivery of multiple systems in internet healthcare. Therefore, to enable the interaction of values between heterogeneous blockchains, we propose a cross-chain mechanism based on a generic global relay chain strategy and a scalable heterogeneous multi-chain system. Also, an unused transaction output (UTXO) verification mechanism based on RSA accumulator is proposed to address the shortcomings of using simplified payment verification (SPV) to verify transactions. In this paper, five experimental tests were performed: pressure, stability, response time, throughput, and latency. Experiments show that its computational complexity for cross-chain transaction validation remains constant as the number of transactions increases. Thus, an efficient cross-chain value transfer is achieved.

Keywords: internet healthcare; data silos; cross-chain; relay chain; consensus.
