The Sui blockchain has achieved a significant performance milestone after its mainnet surpassed 6 million transactions per second (TPS) following the implementation of programmable lightning tunnels, according to Adeniyi Abiodun, co-founder and chief product officer at Mysten Labs.
The announcement underscores continued efforts by Mysten Labs, the company behind the Sui blockchain, to enhance the network’s scalability and transaction-processing capabilities as competition among high-performance blockchain platforms intensifies. The latest upgrade is intended to strengthen the network’s ability to process large volumes of transactions while maintaining efficient performance for decentralized applications and digital asset services.
The implementation of programmable lightning tunnels has enabled the Sui mainnet to exceed 6 million transactions per second, representing a major scalability milestone for the blockchain network.
The reported increase in throughput reflects ongoing infrastructure improvements designed to support growing demand for decentralized finance (DeFi), gaming applications, tokenized assets, and other blockchain-based services that require rapid transaction execution. High transaction capacity has become an important competitive factor as blockchain developers seek platforms capable of handling enterprise-scale workloads without sacrificing efficiency.
Infrastructure Expansion Continues
The transaction milestone forms part of a broader roadmap through which Mysten Labs is expanding the technical capabilities of the Sui ecosystem. Alongside improvements to network performance, the company has outlined additional features intended to enhance both privacy and financial services on the blockchain.
Abiodun previously indicated that confidential transfers using range proofs are under development for the Sui blockchain. The planned functionality is expected to enable private transactions while maintaining the cryptographic assurances necessary for blockchain verification. If implemented as planned, the feature would provide users with stronger transaction privacy without compromising the integrity of the underlying network.
The introduction of confidential transfers reflects increasing industry interest in privacy-preserving technologies that allow users and enterprises to protect sensitive financial information while continuing to operate within transparent blockchain environments.
Mysten Labs is also developing confidential transfers using range proofs, a feature intended to strengthen transaction privacy while preserving blockchain security and verification.
DeFi Expansion Targets Asian Equities
Beyond network infrastructure and privacy enhancements, Mysten Labs is also preparing to broaden Sui’s decentralized finance ecosystem. Abiodun indicated that the blockchain’s DeFi platform is expected to support continuous, around-the-clock trading of Asian equities, expanding the range of financial products available within the ecosystem.

According to the update, a waitlist has already been opened for prospective users interested in accessing the planned service. Continuous trading of tokenized or blockchain-based financial assets could provide market participants with greater flexibility compared with conventional equity markets that operate during fixed trading hours.

The initiative aligns with a broader trend across the blockchain industry to integrate traditional financial assets with decentralized infrastructure, allowing users to access investment opportunities through blockchain-based platforms while benefiting from continuous market availability.
Focus on Scalability and Product Innovation
The latest announcements illustrate Mysten Labs’ strategy of advancing multiple areas of the Sui ecosystem simultaneously, including network scalability, transaction privacy, and decentralized financial services. By improving the blockchain’s underlying infrastructure while introducing new user-focused capabilities, the company aims to position Sui as a competitive platform for developers, enterprises, and financial applications.
The combination of ultra-high transaction throughput, planned confidential transfers, and continuous DeFi trading for Asian equities demonstrates Mysten Labs’ broader strategy to expand Sui’s infrastructure and application ecosystem.
As blockchain adoption continues to grow across both consumer and enterprise markets, the ability to process millions of transactions per second while supporting privacy-enhancing technologies and expanded financial services could strengthen Sui‘s position among next-generation Layer-1 blockchain networks. Market participants and developers are likely to monitor the rollout of these planned features as the ecosystem continues to evolve.
