About Sui
Unlock the freedom to build powerful on-chain assets
Sui is a permissionless layer 1 blockchain designed to be both developer and user-friendly. It can support a wide range of application development with unrivaled speed at low cost.
- Unmatched scalability, instant settlement.
- A safe smart contract language accessible to mainstream developers.
- Ability to define rich and composable on-chain assets.
- Better user experience for web3 apps.
- Narwhal and Bullshark DAG-based mempool and efficient Byzantine Fault Tolerant (BFT) consensus.
Sui uses objects as its basic unit of data storage rather than accounts, as happens on most other blockchains. Developers define, create, and manage these programmable objects that represent user-level assets. An object has distinct attributes, including ownership, whose values can be updated based on the governing logic of the smart contract that created it.
Most assets on Sui are owned by a single address, recorded as a data value for the object. These are referred to as “owned objects.” Transferring ownership simply requires a change of that value. Transactions that are independent of any other action being performed on the network, such as an asset transfer, are considered simple or “single-writer” transactions and can be processed without going through consensus.
Not only can a person own an object, but objects can own objects on Sui, allowing them to combine into a whole new asset, which is often referred to as composable assets.
