Underlying technology  

Polkadot is built on a unique multi-chain architecture, comprising a relay chain, parachains, and bridges. This architecture enables parallel processing, interoperability, and governance across independent blockchains within the Polkadot network.

• Relay Chain: The relay chain serves as the main blockchain in the Polkadot network, coordinating consensus and governance among parachains. It maintains the overall network security and facilitates cross-chain communication and asset transfers.
• Parachains: Parachains are independent blockchains that connect to the Polkadot network via the relay chain. Each parachain has its own set of validators and consensus mechanism, allowing for customizable governance, token economics, and application logic. Parachains can interact with each other and with external blockchain networks through bridges.
• Bridges: Bridges enable interoperability between Polkadot and other blockchain networks, facilitating the seamless transfer of assets and data across disparate ecosystems. Bridges are implemented as specialized parachains or smart contracts that monitor and relay cross-chain transactions between different networks.
• Consensus Mechanism: Polkadot uses a hybrid consensus mechanism known as nominated proof-of-stake (NPoS) to secure the network and validate transactions. Validators are selected through a stake-weighted nomination process, where token holders delegate their stake to trusted validators who participate in block production and consensus.
• Governance Framework: Polkadot features an on-chain governance framework that allows token holders to propose, vote on, and enact changes to the protocol parameters, upgrades, and network governance rules. This decentralized governance model ensures community participation, transparency, and adaptability in the evolution of the Polkadot network.

How are Polkadot (DOT) tokens created and distributed?  

Polkadot's native token, DOT, was distributed through a series of public and private sales, as well as a genesis block allocation to early contributors and stakeholders. The initial total supply of DOT tokens was capped at 10 million, with a planned inflationary schedule to gradually increase the token supply over time.

• Staking and Governance: DOT tokens play a vital role in the Polkadot network as a means of staking and governance. Token holders can stake their DOT to become validators or nominate validators to participate in block production and consensus. Validators are rewarded with staking rewards and transaction fees for their services, while token holders can participate in on-chain governance by voting on proposals and referenda.
• Inflationary Mechanism: Polkadot employs an inflationary mechanism to incentivize network participation and security. New DOT tokens are minted and distributed as staking rewards to validators and nominators, as well as treasury funds for network development, ecosystem grants, and community initiatives. The inflation rate and distribution schedule are determined by on-chain governance parameters and may be adjusted over time based on network conditions and consensus.
