Secure the
Network Through Decentralization
Validators are key to Sui’s operations and performance
Independent validators are the backbone of the Sui network. Validators run unique instances of the Sui software on independent machines and are collectively responsible for securing the network. They process transactions and participate in consensus to ensure Sui is the safest network possible.
As a permissionless network, anyone with the appropriate setup and sufficient stake can become a validator. Sui uses Delegated Proof-of-Stake (DPoS) to determine which validators operate the network and their voting power.
How Delegated Proof-of-Stake (DPoS) Works
Operations are processed by a fixed set of validators, each with a specific amount of stake from SUI token holders. A validator's share of the total stake on the network determines each validator’s voting power for processing transactions. Staking SUI implies that the SUI tokens are locked for a fixed duration, called an epoch. SUI token holders are free to withdraw their SUI or to move their stake to a new validator when an epoch changes.
Staking rewards for good behavior
Validators provide a service to Sui by operating and securing the network. In exchange, they are compensated with commissions from staking rewards. In the early phases of the network, staking rewards are made up of stake subsidies plus gas fees. The subsidies are necessary as gas fees will likely be relatively low. In the long run, the entirety of rewards will be gas fees.

Sui Foundation Stake Support and Terms
Decentralization is at the core of the Sui Foundation’s mission. In order to deliver a fully open, permissionless, and performant network, voting power must be in the hands of many. To that end, the Sui Foundation intends to deploy its SUI treasury to support fair, distributed, and decentralized stake distribution for validators operating the network.
Sui Foundation Staking Principles
In the spirit of openness and equity, the Sui Foundation will initially stake SUI tokens across the entire validator set. Over time, the Sui Foundation will begin routine re-evaluations of its staking decisions and rebalance the distribution, based largely on a validator’s adherence to Sui’s staking best practices. These best practices are drawn from the experience and input of current validators and other community members. New operators interested in becoming a validator will be able to apply for stake from the Sui Foundation through the Foundation's SUI Delegation Program.
The Sui Foundation’s staking decisions aim to assist the community with simultaneously solving global (network) and local (individual) optimization problems. The Sui Foundation will work together with Sui’s validators and is committed to transparency in its decision making.
The Sui Foundation will review the entirety of its stake decisions on a monthly cadence. These decisions will be informed by the data collected on validator performance throughout the previous epochs.
The Sui Foundation aims to launch the SUI Delegation Program in the near future, providing new validators the opportunity to apply for Foundation stake and onboard into Sui operations.
Sui staking best practices
The Sui Foundation believes that these best practices, derived from validator and community member input, are conducive to performant network operations and community success, whether or not a validator receives stake from the Sui Foundation. The Sui Foundation may base its own staking and unstaking decisions on this information in order to help the community ensure that the network performs its best.
Tokenomics Best Practices
Follow maximum commission mandate:
Stake rewards should increase proportionally with a validator’s share of staked SUI meaning validators, with more stake receive relatively more commissions than validators with lower stake. Therefore, receiving a larger amount of Sui Foundation stake should result in a lower validator commission.
The following commission caps represent best practice recommendations and are recommended to apply to the initial amount of SF delegated stake. For example, if the Sui Foundation stakes 10M SUI tokens with a given validator, the best practice maximum commission applies at the 10M SUI token level regardless of whether the original amount compounds into a larger stake as it accrues stake rewards over time.

Participate in Gas Price Survey:
A validator with staked SUI from the Sui Foundation should participate in the gas price survey at least once a week. The validator should send a transaction to update its gas price object at least once every 7 epochs.
No rewards slashing from
Tallying Rule:
A validator who gets a 0 score from two-thirds of its peers will have its rewards slashed. Causes for slashing include low operational performance, malicious behavior, and poor community membership.
