There are mainly two implementation methods for cross-chain technology: sidechains and atomic swaps. A sidechain refers to a branch chain located next to the main chain, which enables asset transfers through specific cross-chain solutions. Atomic swaps refer to atomic operations for on-chain activities (such as asset exchanges) between two chains. The goal of cross-chain technology is to enhance the interoperability of blockchain networks and promote seamless collaboration and communication between  various blockchain platforms."}]}],"pr":"e489511a0259ab2082cd55dce5c109dffae8497ddc9246ed5f38fb71c4deb77c"}
