Sui Architecture
Sui is a layer 1 blockchain. Learn more about the network's architecture.
Components of Sui
Sui is a layer 1 blockchain that performs its own consensus and validation of transaction blocks. Sui is comprised of the blockchain itself, the blockchain's activity such as transactions, and the validator entities that verify this activity.
Networks
Sui operates multiple networks including Mainnet for production, Testnet for staging, Devnet for developing new features, and Localnet for local development.
Storage
Historical data and storage pricing provide insights into the cost of operations on the Sui network.
Consensus
Overview of the Sui consensus mechanism.
Epochs, Equivocation, and Reconfiguration
Epochs define time periods on Sui where the validator set remains unchanged. Equivocation occurs when objects are used incorrectly across transactions. Reconfiguration adjusts network parameters at epoch boundaries.
Security
Assets on Sui, including coins and tokens, are types of objects, and can only be used by their owners unless otherwise defined according to predefined logic in a smart contract.
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.
