The Sui blockchain has emerged as an innovative layer-1 (L1) protocol, integrating advanced technologies to tackle common trade-offs associated with such foundational layers. Cointelegraph Research dives into the specifics of this newcomer in the blockchain arena.
Sui adopts the Move programming language, tailored for asset representation and access control. This piece delves into Sui’s object-centric approach to data storage, its impact on transaction processing, and its comparative advantages over traditional account-based paradigms.
### Object-Oriented Paradigm of Sui
Inspired significantly by the Diem blockchain, Sui leverages the Move programming language, originally designed to enforce asset management and access control through a specialized type system. Building upon this foundation, Sui introduces an object-centric data storage model, treating assets and smart contracts as intricate objects.
In contrast to conventional models where transactions modify balances or follow a UTXO (Unspent Transaction Output) approach with straightforward inputs and outputs, Sui’s object model manipulates objects as inputs, transforming them into output objects. Each object keeps a record of the preceding transaction’s hash, akin to the UTXO model but more expansive and potent. See the comparison below:

### Move’s Linear Logic Integration
Move’s utilization of linear logic underpins the object-oriented model, facilitating secure software development. Linear logic, also known as resource logic, ensures that digital asset representations cannot be duplicated or inadvertently destroyed. During asset-involved transactions, Sui Move guarantees that asset states reflect transaction outcomes, consuming and producing assets in their updated forms.
Objects in Sui can define access controls and permissions, bolstering asset security post-transaction. This mitigates vulnerabilities prevalent in account-based chains, such as reentrancy attacks, where external calls permit repetitive actions, resulting in unauthorized state changes.
### Object-Centric Model Advantages
Sui’s object-centric model proves particularly advantageous in managing complex assets like non-fungible tokens (NFTs). Unlike Ethereum’s address-bound NFTs requiring intricate contract calls and state updates, Sui treats each NFT as a distinct, inherently governed object. This streamlined approach aligns NFT behaviors with Move language primitives, minimizing overhead and potential errors.

### Blockchain Performance and Parallelization
The object-oriented model simplifies sharding and parallelization on the Sui blockchain, complemented by recent consensus mechanism updates achieving a swift time-to-finality of approximately 390 milliseconds. This setup potentially supports over 100,000 transactions per second, surpassing many layer-1 blockchains.

### Database Sharding on Sui vs. Account-Based Chains
Addressing scalability concerns, Sui’s object-centric model handles each object independently, sidestepping global state synchronization requirements across shards. This autonomy minimizes cross-shard communication complexities, facilitating efficient parallel processing without compromising security or decentralization.
