 ## Approach
 
 `Astar` reuses Polkadot’s so-called **v1** governance model due to its practicality. The core idea is to further decentralize the network, but not completely re-invent the wheel.

 Astar Network is transitioning its governance system from off-chain voting through Townhall to on-chain voting. This change empowers Astar stakeholders to directly vote on key network proposals and decisions on-chain. Astar governance allows ASTR token holders to influence and participate in decisions that affect the network, such as protocol improvements, runtime updates, and dApp Staking applications.
 
 To interact with the on-chain governance, users have two primary interfaces to choose from: [Subsquare](https://www.subsquare.io/) or the traditional [Polkadot.js](https://polkadot.js.org/apps/) interface. Subsquare provides a user-friendly interface for governance participation, while Polkadot.js offers a more technical approach.
