Interoperability

The feature to move assets and data between chains is an important aspect of the parallel chain environment. Applications use parallel chains for inexpensive & fast transactions, but the results of these transactions should be easily transferable cross-chain. This is sometimes referred to as a 2-way peg.

Since chains are independent of one another, assets/data are typically locked on one chain and minted on another. When resources are transferred back, they are burned and unlocked. The Token Bridge application illustrates this architecture. Smart contracts deployed to both networks are connected by a bridge oracle where bridge services confirm and sign cross-network transactions.
