What is Sui Staking?
Sui is a Layer 1 blockchain that uses a Delegated Proof-of-Stake (DPoS) consensus mechanism. Staking is the process of locking your SUI tokens with a validator to help secure the network, and in return you earn staking rewards every epoch.
How Does Staking Work on Sui?
When you stake SUI, you delegate your tokens to a validator of your choice. Validators run the infrastructure that processes transactions and produces blocks. The more SUI staked with a validator, the more voting power they have in consensus.
- Choose a validator — research their APY, commission rate, uptime, and community trust
- Delegate your SUI — send a staking transaction through your wallet
- Earn rewards — rewards are distributed at the end of every epoch (~24 hours)
- Unstake anytime — your SUI and accumulated rewards are returned immediately
What is an Epoch?
An epoch on Sui lasts approximately 24 hours. At the end of each epoch, the network calculates and distributes staking rewards to all delegators based on their staked amount and the validator's performance. New stakes become active at the start of the next epoch.
What are the Benefits of Staking?
- Earn passive income — typical APY ranges from 1.5% to 3% depending on the validator
- Secure the network — staking strengthens Sui's security and decentralization
- No lock-up period — unlike many other chains, Sui allows immediate unstaking
- Low minimum — you can stake as little as 1 SUI
Native Staking vs Protocol Staking
Native staking means delegating directly to a validator through the Sui system contract. Your tokens remain in your control — only the validator can use the voting power, not your tokens.
Protocol staking (liquid staking) goes through protocols like Aftermath, Haedal, or SpringSui. You receive a liquid staking token (LST) in return that represents your staked SUI plus rewards. This lets you use your staked assets in DeFi while still earning staking rewards.
