What is Sui?
Sui is a proof-of-stake Layer 1 blockchain that runs smart contracts in the Move language. It uses Mysticeti, a DAG-based consensus that commits blocks in 3 message rounds. SUI pays gas and staking, and total supply is capped at 10 billion. The independent Sui Foundation supports the ecosystem.
How Sui works
Sui runs in epochs.
At the start of each epoch, SUI holders' stake forms a new validator committee, validators submit the lowest gas price they will accept, and the protocol sets the reference gas price at the 2/3 percentile by stake. Validators rate each other during the epoch. Those that fail to honor the reference price get lower stake rewards at the end, set by a stake-weighted median of those ratings.
Every transaction pays computation gas plus a storage fee. Storage fees go into a storage fund that is counted as stake. Its rewards pay validators for holding data written before they joined, and the fund never pays out its principal. Delete stored data and you get back 99% of the storage fee you paid. At the end of each epoch, rewards equal computation fees plus a temporary stake subsidy.
How to start with Sui
- You need a Sui-compatible wallet, and most include staking and unstaking buttons.
- Every transaction carries a gas budget in SUI: the minimum is 2,000 MIST (0.000002 SUI) and the maximum is 50 SUI.
- The budget must cover the worst case, so it is often set well above what you end up paying.
- Staking wraps your SUI in a stake object that you hold yourself and that records the validator pool and activation epoch.
- You only earn for epochs where the stake was active the whole time.
- Unstaking returns principal and rewards together as SUI.
- Rewards compound through each validator pool's exchange rate, which rises at every epoch boundary as rewards come in.
Sui fees and limits
Computation is priced at or near the reference gas price, and you can add a tip when the network is congested. The storage price is fixed by governance and changes rarely, targeting the dollar cost of storing data. If your budget does not cover computation, the whole budget is charged. If it covers computation but not storage, you pay for computation and input object mutation.
Risks to know before using Sui
- Your staking return depends on the validator you pick.
- A validator can change its commission at any time without notice, and a validator punished under the tallying rule gets no rewards for that epoch, so neither do you.
- Initial investors were blocked from transferring their SUI for one year after mainnet, a cliff that ended in May 2024, and the rest of the supply unlocks on a multi-tier vesting schedule.
- Sui states it ran no airdrop for its mainnet launch.
