The Sui Foundation recently conducted a series of tests to determine the current peak throughput and time to finality for various workloads on the Sui network. A year after its announcement, the Sui network has made significant strides in performance, becoming a promising decentralized protocol for the future.

Key Findings

  • The Sui network, consisting of 100 globally distributed validators, achieved peak throughput ranging from 10,871 TPS to 297,000 TPS on different workloads.
  • Sui's time to finality is approximately 480 milliseconds, providing rapid transaction confirmations.

Performance Evaluation

To measure the performance of the Sui protocol, the foundation used a globally-distributed setup that closely mirrors the mainnet in terms of hardware configurations, number of validators, geographic distribution, and voting power distribution. The tests were conducted using 100 validators, 24-core AMD hardware, 256GB memory, and 25Gbps NIC.

Measuring Throughput with Programmable Transaction Blocks (PTB)

Sui's core developer primitive, PTB, allows for a complex and composable sequence of transactions. Chained transactions in a PTB can execute and fail atomically, providing increased efficiency and expressivity. Each PTB can support up to 1024 transactions, enabling Sui to handle large workloads and reduce transaction fees for users.

The Challenge of Measuring Throughput

Transactions Per Second (TPS) is a commonly used metric to measure a blockchain protocol's capacity. However, measuring the number of PTBs executed per second doesn't accurately reflect Sui's computational capacity. As the average PTB size increases, Sui's throughput increases, but the PTB/second metric would remain unchanged. Therefore, the foundation has chosen to measure the number of individual transactions within a PTB executed per second as a more consistent and practical metric.

Time to Finality

Finality in blockchain refers to the point where a transaction is considered irrevocable and cannot be modified or reverted. For this performance update, the Time to Finality measures the point in the transaction lifecycle where both the transaction itself and its effects are final and can be used in subsequent transactions. Sui's Time to Finality is approximately 480 milliseconds, with a 95th percentile latency of around 550 milliseconds.

Future Optimization and Scalability

The Sui protocol has made significant progress in its performance, but there are still many opportunities for optimization and scalability. In the near future, the Sui Foundation plans to refine the following aspects:

  • Scalability and coverage of benchmark tooling
  • Horizontal scalability to support intra-validator scaling across multiple machines
  • Resilience to under-performance of individual validators

As the Sui protocol evolves and its performance improves, the Sui Foundation will continue to share updates with the community for feedback and consideration. With its impressive throughput and time to finality, the Sui network is poised to make a significant impact in the world of decentralized systems.

The SUI Network is a high-performance public blockchain developed by former Meta engineers. Built with the Move programming language, it prioritizes security, scalability, and upgradability.

What is POAP?

POAP, or Proof-Of-Attendance Protocol, is a mechanism for distributing encrypted badges to record and commemorate specific events. POAP tokens can serve as proof that a user attended an event or as collectible items, similar to concert tickets or commemorative badges.

Event organizers typically use POAP to distribute tokens to participants, who can then collect unique POAP tokens (NFT badges) to remember their attendance at an event.

Introducing SUIA: The First POAP Application on the SUI Network is the first POAP application on the SUI blockchain, currently launched on SUI's devnet. In the future, Suia will have multiple purposes, such as event tickets, contribution awards, and gaming, providing a new immersive, gamified interaction method between web3 brands and users.

What are the features of SUIA?

Anyone can create POAP events on Suia, with all creation and distribution occurring transparently on the SUI blockchain. Users own their Suia assets, and the unique architecture and parallel performance of the SUI blockchain allow Suia to combine and create more gameplay possibilities, accommodating large-scale user participation, low latency, and low fees, facilitating connections with the web2 application market.

How to use SUIA?

  1. Visit the Suia website at, click "connect wallet" to link a wallet, currently supporting Sui wallet and Suiet Wallet.

  2. After connecting the wallet, click "create Suia" to experience creating a POAP NFT distribution event on the SUI blockchain. Follow the prompts to upload the NFT's type, name, description, amount, and whitelist restrictions if needed. Click "create" to complete the process, which requires a small amount of SUI tokens in the devnet environment.

  3. After creating the event, it will appear on the homepage, allowing other users to discover and claim your POAP.


Suia, developed by the Mynft team (creators of the first vote-to-earn web3 platform on the Flow blockchain), has a mature market and development experience, as well as a solid community foundation. Developing Suia on the SUI blockchain leverages the team's NFT expertise while filling the gap in POAP applications.

With a well-developed product and clear roadmap, strong project collaboration, and community management capabilities, Suia has attracted over 6,000 participants on its first day of testing. SUI World DAO will continue to monitor Suia's future collaborations and user growth as the SUI mainnet launches.

In the world of blockchain, speed and efficiency are vital for the success of any platform. Enter Sui Blockchain, a platform that promises to deliver low latency transaction processing and smart contract execution.

Sui and

One of the unique features of Sui Blockchain is its ability to distinguish between different kinds of object ownership. Unlike other blockchain platforms where every contract and object is mutably shared, Sui allows an object to be owned by an address and can be mutably owned, immutably owned, or mutably shared. This feature is leveraged for parallel execution of smart contracts and asset management.

Sui uses a decentralized permissionless smart contract platform, biased towards low-latency management of assets. It uses the Move programming language to define assets as objects that may be owned by an address. The platform is maintained by a permissionless set of authorities that play a role similar to validators or miners in other blockchain systems.

To achieve low latency, Sui separates transaction processing into two phases: 1) acquiring distributed locks at the granularity of objects and 2) executing the transaction and committing its effects.

Phase one is performed through a reliable broadcast primitive that requires no global synchronization within the authority, allowing for scalability through sharding. For transactions involving shared objects, sequencing is required using a consensus protocol.

Sui aggressively reduces bottlenecks and points of synchronization requiring global locks within authorities, allowing for quasi-linear scaling with increased resources. The platform also allows for parallel execution of smart contracts, with Move virtual machines on multiple cores or physical machines reading versioned input objects, executing, and writing resulting objects from and to stores.

The consistency requirements on stores for objects and transactions are very loose, allowing scalable distributed key-value stores to be used internally by each authority. Sui uses a Byzantine consistent broadcast protocol between authorities to ensure the safety of common operations on assets, ensuring lower latency and better scalability as compared to Byzantine agreement.

Overall, Sui Blockchain's design choices and optimizations make it a promising platform for applications that require fast and efficient processing of transactions. Its ability to 1) distinguish between different kinds of object ownership, 2) acquiring distributed locks at the granularity of objects, and 3) parallel execution of smart contracts are key features that set it apart from other blockchain platforms. With Sui Blockchain, the future of fast and efficient transaction processing is here.
