The Sui mainnet has officially gone live on May 3, 2023 — marking a pivotal milestone in the evolution of one of the most anticipated Layer 1 blockchains. Thanks to the relentless efforts of the development team, node operators, and unwavering support from the global community, Sui is now open for decentralized innovation at scale.
This launch signifies more than just a technical achievement; it represents the beginning of a new era for scalable, secure, and user-friendly blockchain applications. With its unique object-centric data model and parallel execution engine, Sui is engineered to deliver instant transaction finality and handle high-throughput workloads — making it ideal for everything from DeFi and NFTs to gaming and social platforms.
As the mainnet goes live, a vibrant ecosystem of projects launches simultaneously, offering users immediate access to core functionalities like staking, asset trading, wallet integration, and on-chain data exploration.

What Makes Sui Different?
Sui stands out in the crowded blockchain landscape through several key innovations:
- Object-Centric Architecture: Unlike traditional account-based models, Sui treats every digital asset as a distinct object with its own ownership and behavior rules. This enables more intuitive smart contract design and efficient state management.
- Parallel Transaction Processing: By leveraging the Narwhal & Tusk consensus mechanism, Sui can process non-overlapping transactions in parallel — achieving theoretical throughput in the hundreds of thousands of transactions per second (TPS).
- Instant Finality: Transactions are finalized in approximately 480 milliseconds, enabling real-time user experiences that rival traditional web2 applications.
- Move Programming Language: Built on a secure-by-design language that prevents common vulnerabilities like reentrancy attacks, Sui enhances smart contract safety.
These features collectively position Sui as a powerful infrastructure layer for the next generation of web3 applications.
Sui Explorer: Your Gateway to On-Chain Activity
With the mainnet launch, Sui Explorer — the official block explorer — is now fully operational at suiexplorer.com. It serves as a transparent, real-time dashboard for monitoring network activity and verifying transactions.
Key capabilities include:
- Viewing real-time metrics such as TPS, active addresses, and transaction volume
- Searching and tracking individual assets, smart contracts (called "packages" in Sui), and wallet activities
- Auditing validator performance and stake rewards
- Locating geographically distributed full nodes across 84 countries
- Debugging and validating smart contract interactions with detailed execution traces
Whether you're a developer testing dApps or a user managing digital assets, Sui Explorer provides the transparency and reliability needed to navigate the network confidently.
Ecosystem Projects Launching at Genesis
A diverse range of projects has launched alongside the mainnet, spanning critical sectors of the web3 economy:
DeFi Platforms
Early decentralized exchanges and liquidity protocols are live, enabling token swaps and yield generation from day one.
NFT Marketplaces & Gaming
NFT platforms allow creators to mint and trade digital collectibles with near-instant confirmation times. Game studios are already deploying on-chain assets and in-game economies powered by Sui’s low-latency infrastructure.
Wallets & Identity Tools
User-friendly wallets support seamless onboarding, private key management, and multi-chain interoperability. Some integrate social recovery features for enhanced security.
Launchpads & Developer Infrastructure
New launchpads offer fair distribution mechanisms for emerging projects, while developer tools provide SDKs, APIs, and testing environments to accelerate dApp deployment.

Public RPC Endpoints and Network Performance
Since the launch of the permanent Sui testnet on March 30, network performance has consistently improved. The system has demonstrated peak throughput approaching 300,000 TPS, with average finality times around 480 milliseconds — among the fastest in the industry.
As of mainnet launch, there are over 41,976 testnet and devnet nodes operated by community members across 84 countries, showcasing strong decentralization and global participation.
Public RPC endpoints are available for developers who want to connect applications without running their own infrastructure. These endpoints enable seamless integration with dApps, wallets, and analytics platforms.
Validators play a crucial role in securing the network. You can view real-time details about validator performance, uptime, commission rates, and APY using Sui Explorer’s validator dashboard.
Sui v1.0.0: Core Protocol Upgrades
The mainnet launch coincides with the release of Sui v1.0.0, a production-grade software version that introduces critical improvements and new API endpoints:
API Behavior Changes
sui_getTransactionBlocknow returns errors in anerrorsfield instead of failing outright when balance changes or object mutations occur — improving debugging clarity.sui_executeTransactionBlockno longer attempts to compute balance or object changes if local execution times out (isExecutedLocally = false), avoiding misleading error messages likeObjectNotFound.
New API Methods
suix_getValidatorsApy: Retrieves annual percentage yield (APY) values for all active validators based on their stake pool exchange rates — essential for stakers evaluating returns.suix_subscribeTransaction: Allows clients to subscribe to transaction streams usingTransactionFilter, enabling real-time event monitoring for wallets and analytics tools.
These updates reflect Sui’s commitment to developer experience, network stability, and long-term scalability.
