Sui's unique object-based infrastructure and the Move programming language make it a go-to platform ... More for DeFi, gaming and NFTs.
Sui is a Layer-1 blockchain designed to optimize speed, scalability and low transaction costs. Officially launched in 2023, Sui runs decentralized apps and play-to-earn games quickly and smoothly, giving users a streamlined experience.
This guide explains what makes Sui unique, how it works and why it's gaining traction among crypto investors and developers.
Mysten Labs, a team comprised of former Meta engineers, built Sui. The Layer-1 blockchain uses Move, a smart-contract programming language and unique object-based model, to process transactions in parallel. This leads to faster confirmation times and supports high-throughput applications like gaming, NFTs and DeFi.
The network's native token, SUI, is used to pay transaction fees, secure the network through staking and vote on governance decisions. Developers and users are drawn to Sui's ability to run advanced, data-heavy apps quickly and smoothly, making it a promising platform for building next-generation decentralized apps.
Sui was created by former Meta engineers who worked on the Diem blockchain project. Led by CEO Evan Cheng, the team built a faster, more efficient Layer-1 network and developed the Move programming language to simplify building decentralized apps.
By treating each asset as a separate object, Sui speeds up transactions and avoids delays tied to account balances. This design makes it attractive to developers and institutions looking for performance and security.
Unlike traditional blockchains, Sui runs on a unique architecture that allows it to process many transactions simultaneously rather than lining them up in a strict order. It does this by focusing on individual pieces of data, called objects, rather than entire accounts. Two transactions can be processed in parallel if they don't touch the same object. This makes Sui much faster and more scalable than blockchains that rely on every validator reviewing every transaction.
Smart contracts on the network are written in Move, a programming language also developed by Meta. Move allows developers to define how assets are created, transferred, and updated as programmable objects. These objects operate independently, making it easier to process many transactions simultaneously. Validators, also known as authorities, manage the network using a system that ensures speed and security.
SUI is Sui's native token. It is used to pay transaction fees, secure the network through staking and participate in governance. With a total capped supply of 10 billion tokens, SUI was designed to promote long-term economic sustainability, avoiding the rapid inflation or speculation in many other crypto projects. Importantly, no airdrops were offered at launch, prioritizing long-term stability over short-term hype.
As a whole, the network operates on a delegated proof-of-stake model. Users can stake their SUI with validators to help secure the system and earn rewards, which are distributed every 24 hours, including gas fees and protocol subsidies. SUI holders also have governance rights, allowing them to vote on network upgrades and proposals. A unique storage fund collects user fees to cover long-term data costs, reward validators and reduce the circulating supply of SUI, giving the token deflationary traits. Validator rewards are based strictly on stake size, with staking pools using exchange rates to compound earnings over time automatically.
Currently, Sui is working to implement 'SIP-39', which lowers the barrier to becoming a validator by focusing on voting power instead of a fixed token minimum. This opens the network to more participants and strengthens decentralization while maintaining economic security and validator accountability.
Sui differentiates itself from other Layer-1 blockchains with high velocity, low fees, and an object-based data model that allows parallel transactions. Unlike Ethereum's account-based architecture, which processes transactions linearly and can become congested, Sui handles unrelated transactions independently. Because Sui uses the Move programming language instead of Solidity, it offers developers greater control over assets, although Move is still less widely adopted at this time.
Compared to Solana, which is known for speed but has faced reliability issues and high validator hardware demands, Sui offers a more accessible and potentially more stable alternative. Unlike Cardano, which takes a slower, research-driven upgrade approach, Sui focuses on real-time performance and developer usability. These design choices position Sui as a competitive option for building scalable, next-generation applications.
Due to its smaller validator set, Sui is less decentralized than networks like Ethereum or Cardano, but it is actively working to improve this. Initiatives like SIP-39, which base validator eligibility on voting power instead of fixed token amounts, aim to lower entry barriers and encourage broader participation. Sui is expected to support more decentralization and stronger on-chain governance as these features roll out.
Sui is rapidly becoming the go-to platform for bitcoin-based assets and decentralized finance. OKX recently launched xBTC, a new type of bitcoin token, and chose Sui as one of the first blockchains to support it. bitcoin-backed assets make up over 10% of all the value locked in Sui, showing strong growth in this area.
DeFi continues to excel on Sui by moving into real-world asset investing through a new Open Market Group partnership. This lets users create unique tokens called Soulbound Tokens, which give them access to RWAs like property or other assets that earn rewards. Sui is also making waves in gaming. For example, the game XOCIETY teamed up with Adidas to launch limited-edition NFT skins that players can use in the game or trade.
Sui's future is bright as it continues to attract developers, institutions and ecosystem partners. Major initiatives like OKX's xBTC integration, the growth of Bitcoin-backed assets, and partnerships in RWA investing signal growing confidence in the network. Upcoming improvements to decentralization, such as the rollout of SIP-39, aim to make validator participation more accessible and strengthen the network's resilience.
While the recent Cetus exchange hack raised concerns, Sui's rapid response demonstrated its ability to protect users. Validators and ecosystem partners froze $163 million of the $223 million stolen, showing effective crisis coordination and network control. Blockchain security firm Dedaub identified the bug and outlined fixes, helping bolster confidence in future safeguards. Despite the incident, it has led to renewed focus on improving security and transparency, positioning Sui to emerge stronger and more prepared for institutional growth ahead.
Bottom Line
Sui is quickly becoming a key player among emerging Layer-1 blockchains. Its unique object-based infrastructure and the Move programming language make it a go-to platform for DeFi, gaming, and NFTs. The ecosystem is expanding and fueled by RWA integrations and BTC-backed DeFi solutions.
Despite challenges like the Cetus hack, Sui's swift and professional response highlighted its strong coordination and security focus. With upgrades like SIP-39 to improve decentralization and growing institutional partnerships, Sui is well-positioned as a serious contender in the next wave of blockchain innovation.
