Sui Project Overview
Sui is the first tier-one blockchain with no access rights, designed from the ground up to enable creators and developers to create experiences that will satisfy the next billion web3 users. Sui is horizontally scalable to support the development of a wide range of applications with unparalleled speed at low cost.
It is a smart contract platform supported by a set of non-authorized validators that play a role similar to validators or miners in other blockchain systems.
Sui is written in Rust and supports smart contracts written in the Move programming language to define assets that can have an owner. Move programs define operations on these assets, including: custom rules for creating them, transferring these assets to new owners, and operations that mutate the assets. To learn about the differences between basic Move and Sui Move, see How Sui Move differs from basic Move.
Sui tokens and validators
Sui has its own fixed-stock SUI token. The SUI token is used to pay for gas and is also used as a delegated rate for validators within an epoch. The voting rights of validators within an epoch depend on this delegated rate.
Sui relies on a number of current peer-reviewed works and years of open-source development.
Transactions
A transaction in Sui is a change on the blockchain. It can be a simple transaction affecting only objects with one owner and one address, such as mining an NFT or transferring an NFT or other token. These simple transactions can bypass the consensus protocol in Sui.
More complex transactions involving objects that are shared or owned by multiple addresses, such as asset management and other DeFi use cases, go through the Narwhal and Bullshark DAG-based memepool and effective Byzantine Fault Tolerant (BFT) consensus.
What Sui is good for
Unmatched scalability, instant calculations
Secure smart contract language available to common developers
Ability to identify rich and composite assets on the chain
Improved user experience for web3 applications
Narwhal and Bullshark DAG based on mempool and Byzantine Fault Tolerant (BFT) efficient consensus.
Sui is the only blockchain today that can scale with the growth of web3 while achieving industry-leading performance, cost, programmability and usability. As we move toward the mainnet launch, we will be demonstrating capabilities that surpass the transaction processing capabilities of existing systems — both traditional and blockchain. We see Sui as the first programmable blockchain platform on the scale of the Internet, the foundational layer for web3.
