Editor's Note: This article explores Sui's core technologies such as object-oriented data model, Sui Move programming language, network structure, and dynamic NFT standards, and introduces its zkLogin that simplifies user experience and DeepBook that provides reliable transaction infrastructure. Although Sui still faces many challenges in the face of mature EVM ecology and other competitors, its unique innovation may help it win a place in the highly competitive crypto market.
Few things generate more buzz in cryptocurrency than Layer1 alts.
While these new chains always promise to be bigger, faster, and better than Ethereum, few can actually deliver on these grand promises. In this cycle, a new group of competitors has emerged, among which venture-backed Sui has received a lot of attention.
Sui, a spinoff of Facebook's terminated Diem project, raised $330 million from institutions such as a16z, Coinbase, and Jump, and went live in May 2023. Since then, its total locked value has exceeded $600 million. Sui also shined in the crypto market this week, leading the alt-layer1 in the past week and month, with an increase of 47% and 13%, respectively.
We’ve discussed Sui before from a project perspective, but haven’t explored its technology in depth.
What’s unique about Sui’s technology?
Sui claims that its blockchain is backed by a number of unique elements. Let’s take a closer look at its object-oriented data model, Sui Move language, network structure, and dynamic NFT standards.
Object-oriented data model
Sui uses a unique object-oriented data model that organizes all data on the chain into unique "objects" that contain ownership, transaction history, and definition details, allowing efficient parallel processing of transactions involving different objects.
Unlike Ethereum, which tracks state through accounts and requires sequential processing, Sui's approach aims to simplify overall state management on the chain, theoretically increasing its scalability. While Solana also supports parallel processing, it also relies on an account model that requires careful conflict management. Sui's object-oriented model aims to avoid these complexities, potentially making it simpler and more scalable.
Sui Move
Sui Move is a modification of Diem's Move language, tailored for Sui's object-oriented model with a focus on security. The language treats resources (such as tokens) as immutable, preventing copying or destruction and eliminating threats such as double spending or reentry attacks. On Sui, the system has built-in security measures such as the Move bytecode verifier, which checks the code before it is allowed on the chain.
Network structure
Sui's object-oriented data model and consensus mechanism are designed to enable it to process large volumes of transactions quickly and efficiently. Instead of batching transactions together, Sui's validator nodes process each transaction individually and in parallel. Different transactions involving different objects can be processed simultaneously without waiting for blocks to fill. Since transactions do not need to wait for each other, this feature theoretically allows Sui to process hundreds of thousands of transactions per second, although its average TPS over the past 30 days is only 36.
Dynamic NFT Standards
Sui developed an NFT standard that supports dynamic usage by default.
Like all Sui data, NFTs are treated as objects, which allows them to change behavior over time. This also supports composability, allowing NFTs to be combined with other assets into more complex assets, or updated with new properties after they are created. For example, an NFT ticket could be updated to show that it has been used, or a work of art could be modified over time. These standards may be attractive to NFT creators, as Sui also supports automatic royalty payments, ensuring that the original creator receives a percentage of future sales directly through the blockchain rather than an external platform.
Other Sui Features
Sui also likes to tout its out-of-the-box solutions, such as zkLogin and DeepBook, which aim to simplify user authentication and lower the barrier to entry for building DeFi on-chain.
zkLogin
zkLogin simplifies on-chain access by allowing users to log in to Sui-based applications using familiar Web2 credentials (such as Google or Twitch), eliminating the need to set up a classic wallet. Although this may seem contrary to the idea of cryptographic privacy, zkLogin uses zero-knowledge proofs to securely link Web2 credentials to Sui addresses.
DeepBook
DeepBook is an open source central limit order book (CLOB) that serves as a shared liquidity layer within the Sui ecosystem. By providing reliable trading infrastructure for DeFi, DeepBook allows developers to focus on building new features without having to manage underlying trading logic or launch their own liquidity pools. With DeepBook, each asset has its own independent liquidity pool, preventing interference between trading pairs and ensuring smoother and faster transaction processing.
Summarize
Although Sui faces challenges in convincing users to abandon EVM or choose it over other alt-L1s with deeper DeFi liquidity (such as Solana), the market is always willing to give a new network a fair chance. However, with the emergence of high-performance EVM chains such as Monad and MegaETH, the competition is becoming more and more fierce, and the road ahead may be more difficult for alt-L1s with a lot of private funding.
Overall, Sui may indeed bring some unique advancements to the crypto space. We’ll leave it to you to judge whether the above features are enough to allow Sui to take a step further in this already very crowded field.
