Specifically, firstly, it is necessary to ensure the interoperability between different shard chains, which can be achieved through cross-shard communication protocols. Secondly, to ensure the consistency and reliability of transactions on multiple shard chains, a cross-shard transaction synchronization mechanism is introduced. In addition, to reduce the propagation delay of transactions on shard chains, an optimized transaction routing  algorithm is adopted. Meanwhile, to guarantee the security of cross-shard transactions, transactions are encrypted and tamper-proofed. In summary, cross-shard protocols, technologies, and mechanisms mentioned above all contribute to realizing cross-shard processing in blockchain."}]}],"pr":"44ae4ce77962b349d12b2fadeb05b9b63c7b2cb00ada81c50709a6451b4bfbff"}
