Users transacting over the Polkadot network have customization rights to redesign the network according to their needs.
With the entire internet processed over a chain, Polkadot allows integrating a developer's transaction with another developer's code, benefiting both the unity and growth of the ecosystem.
All projects on the Polkadot network have the right to develop as they wish. These changes will ensure the system remains constantly updated and perfect. Having updates always available and user-implementable keeps the system perpetually current.

Within the Polkadot system, the cryptocurrency DOT serves three purposes and holds an important place for the system's progression and sustainability. DOT tokens grant governance rights within the Polkadot system, are used for staking to ensure the system's operation, and for bonding in transactions.
