Polkadot is a layer-0 blockchain protocol designed to enable interoperability between multiple purpose-built blockchains, known as parachains, which connect to a central Relay Chain. Founded by Ethereum co-founder Gavin Wood and developed by the Web3 Foundation and Parity Technologies, Polkadot launched its Relay Chain in 2020. Each parachain can be optimised for a specific use case while sharing the security of the Relay Chain through Polkadot’s nominated proof-of-stake consensus mechanism.<\/p>\n
DOT is the native token and serves three primary functions: governance, staking, and bonding. DOT holders vote on protocol upgrades and treasury spending without requiring hard forks. Validators and nominators stake DOT to secure the network and earn rewards. Parachain projects lock DOT via crowdloans or auctions to secure a slot. Polkadot has been transitioning toward a more flexible architecture called Polkadot 2.0, introducing coretime \u2014 a model where blockchains purchase computational time rather than competing in fixed slot auctions \u2014 which is intended to lower barriers to entry.<\/p>\n","protected":false},"excerpt":{"rendered":"

Each can have its own token, governance, and logic while benefiting from Polkadot's validator set. Teams must win a slot auction or purchase coretime, locking DOT in the process.\"},{\"q\":\"How does DOT staking work?\",\"a\":\"DOT holders participate either as validators who produce blocks, or as nominators who back validators with staked DOT. Both earn rewards proportional to their stake. Validators who behave dishonestly risk slashing of staked DOT, meaning nominators share that risk and should evaluate validators carefully.\"},{\"q\":\"What is Polkadot 2.0 and coretime?\",\"a\":\"Polkadot 2.0 replaces fixed parachain slot auctions with a flexible coretime marketplace where teams buy block-production capacity in short increments. This lowers the capital barrier for new projects and increases utilisation of Relay Chain capacity. Coretime can be bought and resold, creating a secondary market for access.\"},{\"q\":\"What are the main risks associated with DOT?\",\"a\":\"DOT faces competition from other interoperability protocols and from Ethereum layer-2s. Parachain or coretime demand affects DOT lock-up and price dynamics. Governance decisions by token holders can alter economics significantly, and staking carries slashing risk.
