Pros and Cons

It's important to note important positives and negatives for parallel chains and their appropriate use cases.

Pros

• Well-established technology backed by extensive research and design improvements.

• Supports general computation and runs on the Substrate framework, allowing compatibility with Vine-native dApps.

• Enables dApps to expand their ecosystem using Substrate-based parallel chains.

Cons

• Reduces decentralization, as parallel chains trade off trustlessness for scalability.

• Uses a similar consensus mechanism but lacks Peer’s security guarantees.

• Requires higher trust assumptions—a malicious quorum of validators could commit fraud.
