Sui is a decentralized, permissionless smart contract network designed for low-latency asset management. It relies on the Move programming language, where assets are modeled as objects that can be held by an address. Move code describes how these strongly typed objects work, including custom logic for creating assets, transferring them to new owners, and performing state-changing operations.

Sui is run by a permissionless group of authorities that function much like validators or miners on other blockchain networks. These authorities use a Byzantine consistent broadcast protocol to keep common asset operations safe, aiming for lower latency and improved scalability relative to full Byzantine agreement. For safety of shared objects, it only needs Byzantine agreement. Governance-related tasks and checkpointing are handled off the critical latency path. Smart contract execution is also naturally parallelized when possible. Sui provides light clients that can verify reads, as well as full clients that can review every transition for integrity. Together, these features support trust-minimized bridges to other blockchains.
