Polkadot is a sharded blockchain which allows for autonomous chains, or parachains, to transfer data between each other and operate with a shared security model.Stake Now
Staking requires active participation to earn rewards but also has risks. Active participation creates new requirements for investors such as operating secure infrastructure 24/7/365, staking optimization, rewards claiming and tax reporting
Stakers secure the blockchain by staking, or delegating tokens to validators, who participate in consensus and validate transactions. Rewards are earned for performing network operations and staked funds may be slashed for unavailability or malicious behavior.
Stakers sign a transaction with their private key that bonds, or delegates their tokens to a validator node.
Validators perform network operations such as participating in consensus or signing in distributed signing groups.
Inflation-funded block rewards and network-based transaction fees are earned in return for good validator performance.
Staked funds are placed at risk and can be penalized, or slashed if a validator node is unavailable or acts maliciously.
