# Peg Zones Once the right blockchain is found for the hub, peg zones can be enshrined into the hub chain as smart contracts. Then, they no longer need an independent security and incentive model. \ \ By having smart contract runtime on the hub chain, the other notorious bottleneck on IBC can be eliminated: heterogeneous blockchain extensibility. Now, various types of light clients in the form of smart contracts can run on the hub to facilitate communication with different blockchains. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
