Sui Architecture
Sui is a layer 1 blockchain built on a delegated proof-of-stake consensus model. Learn about the core components that make up Sui, including the object model, transaction processing, consensus mechanisms, network environments, and tokenomics.
Components
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.
Consensus
Overview of the Sui consensus mechanism.
Tokenomics
Sui's tokenomics is designed to support the long-term financial needs of Web3. It uses the native SUI token as the currency of the network and to pay for the network's gas fees.
Object Model
Everything on the Sui blockchain is an object that has metadata, a type of ownership, and a referencing scheme.
Epochs and Reconfiguration
Epochs define time periods on Sui where the validator set remains unchanged. Reconfiguration adjusts network parameters at epoch boundaries.
Checkpoint Verification
On the Sui network, checkpoints define the history of the blockchain. Checkpoint verification is how full nodes and other clients guarantee their state is exactly the same as the Sui network.
Storage
Historical data and storage pricing provide insights into the cost of operations on the Sui network.
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.
