Sui Architecture

Sui shares some similarities with other blockchains but is unique in many ways. Use the topics in this section to understand the features that define the Sui network.

Understand Sui security

Sui is designed to provide very high security guarantees to asset owners. Assets on Sui can be used only by their owners, according to the logic pre-defined by smart contracts that can be audited, and that the network will be available to process them correctly despite some of the validators operating Sui not following the protocol correctly (fault tolerance).

Life of a Transaction

The life of a transaction on the Sui network has some differences compared to those from other blockchains.

Consensus

Overview of the Sui consensus mechanism.

Sui Indexer

Sui Indexer is an off-full node data service that serves data from the Sui protocol, including both data directly generated from chain and derivative data.

Sui Storage Cost

Historical data and storage pricing provide insights into the cost of operations on the Sui network.

Protocol Upgrades

The Sui protocol, framework, and execution engine are frequently extended to include new functionality and bug fixes. The upgrade process ensures all clients use the same source.
