- Polkadot staking enables DOT holders to earn rewards by supporting network validators.
- Nominators and pools offer accessible ways to participate with lower risk.
Decentralized networks rely on consensus mechanisms to maintain security and agreement across participants. Polkadot, one of the leading blockchain platforms, uses a variation called nominated proof-of-stake (NPoS), making staking both rewarding and democratic.

How Polkadot Staking Works
Polkadot’s staking process involves two main roles: validators and nominators. Validators are responsible for producing blocks and verifying transactions using the BABE engine. Once blocks are created, GRANDPA confirms their finality through a two-thirds majority of staked DOT.
Nominators, on the other hand, play a more passive role. They vote for up to 16 validators, distributing their stake among those elected. Alternatively, nominators can join staking pools, where an operator manages rewards on a pro-rata basis. Direct nomination requires a minimum of 250 DOT (€818), while pool participation starts with just 1 DOT (€3.62).
Getting Started with DOT Staking
To stake DOT, participants need a digital wallet. Hot wallets like Nova, Subwallet, and Talisman are convenient, while cold wallets such as Ledger offer stronger security. Polkadot uses two accounts: a stash account for holding staked tokens and a staking proxy account for managing rewards and voting.
Staking services and liquid staking platforms, such as Bifrost, simplify participation by issuing representative tokens (vDOT), which can be used in decentralized finance (DeFi) applications. Exchange-traded products (ETPs) like CoinShares Physical Polkadot Staked ETP also provide a liquid way to earn staking rewards.
Rewards and Yields
Validators earn rewards based on era points earned for network participation, with Polkadot averaging 13.08% annual returns as of August 2025. Nominators receive a portion of these rewards, minus validator commission. The network enforces penalties for malicious behavior, ranging from 2% to 100% of a validator’s stake, ensuring network security.
Benefits and Risks of Polkadot Staking
Staking DOT offers potential passive income, especially for validators and informed nominators. Low barriers to entry through pools or services make staking accessible to almost anyone, while supporting network decentralization.
Risks include financial loss from penalties, long withdrawal periods of 28 days, and custodial risk when using third-party services. Proper research on validators and staking strategies is essential for minimizing exposure.
Polkadot Compared to Ethereum and Solana
Polkadot’s staking rewards outperform Ethereum (3.1%) and Solana (5%-7%). While Polkadot requires a lower minimum stake than Ethereum and offers more flexible options than Solana, its withdrawal period is longer. Polkadot also maintains a democratic validator selection process, promoting network security and decentralization.
