Easy Addition of New features

The addition of sidechains enables blockchain developers to add new features to a network without introducing additional security risks. These added features open up the possibility for developers building on top of the network to explore new use cases.

Also, sidechains can inherit some (or all) features (ledger model, consensus mechanism, etc.) from their parent chain, and pair them with features that might not exist on the main chain. For example, a sidechain can combine different security models, consensus protocols, or governance models to create a brand new blockchain that can interoperate with other blockchain networks.

The EVM sidechain is a Cardano sidechain -which is currently underway- this sidechain will enable Solidity DApps and EVM developers to build on the Cardano platform. In this way, developers can easily expand their community's reach into Cardano and benefit from the blockchain's existing capabilities.
