Polkadot (DOT)

Wat is Polkadot?

Polkadot (DOT) is the native token of the Polkadot network, a protocol designed to enable interoperability between different blockchains. It functions as a layer-0 metaprotocol, providing a foundation for a network of user-created blockchains known as parachains. Launched in 2020, the project was co-founded by Gavin Wood, Robert Habermeier, and Peter Czaban. The network operates on a nominated-proof-of-stake (NPoS) consensus mechanism, which is designed to secure the network and validate transactions efficiently. DOT serves several key functions within its ecosystem, including governance, staking for security and operations, and bonding to connect new parachains.

Hoe werkt Polkadot?

Polkadot utilizes a nominated-proof-of-stake (NPoS) consensus mechanism to secure its network and validate transactions. This system involves two primary roles: validators, who produce blocks, and nominators, who select trustworthy validators by staking their DOT tokens. The NPoS model is designed to distribute stake evenly among active validators, enhancing network security.

Validators are responsible for maintaining the network by running a node, validating proofs from collators on parachains, and participating in consensus with other validators. Nominators play a passive but crucial role by delegating their staked DOT to support specific validators, signaling their trust in those participants. This delegation process is fundamental to the network's security model and the selection of the active validator set.

The network's architecture consists of a central Relay Chain that coordinates security and communication between various parallel blockchains called parachains. Transactions are processed on these parachains, which then submit proofs to the Relay Chain for finalization. This structure allows for parallel transaction processing, enabling the network to handle multiple operations simultaneously across different chains.

Polkadot tokenomics

The tokenomics of Polkadot's native token, DOT, are centered on its roles in network security, governance, and parachain auctions. The token has a circulating supply of approximately 1,689,849,731 DOT out of a maximum supply of 2,100,000,000 DOT. The supply is not fixed, as new tokens are issued as rewards for participants in the nominated-proof-of-stake consensus mechanism. These issuance rewards are distributed to validators and nominators for their role in securing the network and validating transactions. A portion of the supply is also used for bonding, a process where tokens are locked to add a new parachain to the network.
