Sui
 (SUI)

SUI is a modern Layer-1 blockchain project developed by Mysten Labs, founded by former Diem engineers from Meta (Facebook). Since its official launch in May 2023, SUI has offered a powerful alternative to established blockchains like Ethereum and Solana, thanks to its innovative architecture and its own programming language, “Move,” delivering high transaction speed and low costs.

Sei
 (SEI)

Sei is a Layer-1 blockchain built for maximum speed in trading digital assets. As the first parallelized EVM blockchain, Sei executes transactions simultaneously and achieves block times of around 400 milliseconds through its "Twin-Turbo" consensus mechanism. This lets Sei combine Ethereum's EVM compatibility with significantly higher transaction throughput, while its interoperability with the Cosmos ecosystem provides access to shared liquidity.

Our opinion

Sui Logo
Sui
 (SUI)
SUI relies on innovative technical approaches with its object-oriented data model and the use of the “Move” programming language, addressing many traditional challenges in blockchain networks. Its architecture allows transactions to be processed in parallel, resulting in impressive performance metrics—for instance, transaction finality times of around 0.4 seconds were achieved during testing. At the same time, SUI employs a two-tier consensus mechanism that routes simple transactions through a fast path and handles complex multi-party transactions via a full BFT consensus. This ensures not only high speed but also flexibility and security. Despite these remarkable technical features, SUI is still in its early stages: it faces challenges such as a limited ecosystem and low recognition compared to established networks. Nonetheless, the project offers a promising technology stack that, if successfully adopted, has the potential to set new standards for performance and user experience.
What is Sui?
Sei Logo
Sei
 (SEI)
Sei is built around parallel transaction execution and positions itself as the first parallelized EVM, directly targeting Ethereum's scalability bottlenecks. By processing multiple transactions simultaneously rather than sequentially, the network can theoretically handle up to 12,500 transactions per second with block times of around 400 milliseconds. On top of that, its Twin-Turbo consensus mechanism uses smart block propagation and optimistic processing to keep latency remarkably low — a real advantage for trading and DeFi use cases that depend on fast execution. That said, there's still a gap between theory and practice: real-world network usage currently sits well below this theoretical ceiling, and the "Giga" upgrade, which targets over 200,000 TPS, is still in the process of rolling out. We're keeping a close eye on how smoothly this upgrade lands and whether real network activity actually picks up to match the infrastructure. Overall, we see Sei as a technically ambitious project with a clear focus on trading performance — one that still has to prove it can deliver on that promise at scale.
