Sui, the Layer-1 blockchain created by Mysten Labs, is setting the stage for a transformative year in 2025, according to co-founder Adeniyi Abiodun. Following a successful 2024 marked by sub-second transaction finality and significant growth in decentralized finance and gaming, Sui is sharpening its focus on scalability, functionality, and providing developer-friendly tools.
Central to these advancements is the introduction of Mysticeti V2, an upgraded consensus mechanism designed to streamline transaction processing. By reducing cryptographic operations and minimizing communication between validators, Mysticeti V2 aims to achieve faster transactions and increased throughput.
In parallel, Sui is rolling out Remora, a horizontal scaling solution that distributes validator workloads across multiple machines. Testing has shown that Remora can process hundreds of thousands of transactions per second, maintaining low fees as the network expands.
To enhance decentralized applications, Sui is introducing Programmable Peer-to-Peer Tunnels, a system for off-chain transactions that minimizes latency and boosts throughput. This is particularly beneficial for real-time applications such as gaming and payments.
Privacy is another key focus for Sui, with plans to integrate zero-knowledge proofs in collaboration with Carnegie Mellon University, enhancing privacy features for users.
On the storage front, Sui is set to launch Walrus in early 2025. Unlike traditional blockchain storage systems, Walrus will offer programmable, scalable storage directly linked to smart contracts. This will allow decentralized applications (dApps) to store large files such as user-generated content and AI models.
For added security, Sui is introducing SEAL, a framework that enables developers to set specific access conditions for stored data, ensuring privacy and control.
In terms of connectivity, Sui is integrating SCION, a secure routing protocol designed to shield the network from threats such as Distributed Denial of Service (DDoS) attacks and BGP hijacks. This protocol ensures the robustness and reliability of Sui’s validator network, even in high-demand situations.
Sui is also enhancing the developer experience with several new tools. RPC 2.0, powered by GraphQL, simplifies data queries, while Bugdar, an AI-driven tool, identifies vulnerabilities in real time. Additionally, the Sui Move Prover allows developers to verify the safety of smart contracts without requiring deep technical knowledge.
