Polkadot holders have complete control over the protocol. All privileges, which on other platforms are exclusive to miners, will be given to the relay chain participants (Polkadot token holders), including managing exceptional events such as protocol upgrades and fixes. Polkadot can be optimized through making the model into which extensions fit as abstract as possible. The Polkadot token serves 3 distinct purposes: governance over the network, operation, and bonding. DOTs are intended to perform three key functions in Polkadot, namely (i) to facilitate participation by holders of DOTs in protocol governance, (ii) to facilitate participation by holders of DOTs in the relay-chain’s Proof of Stake consensus mechanism and (iii) to serve as a value metric.
