A closer look at how Sui’s object-centric model and the Move language can improve blockchain scalability and smart contract development.
The traditional account-based model as used by Solidity, on the other hand, requires that developers implement additional checks to prevent such bugs. For example, reentrancy attacks need to be avoided by following apattern. All state-changing operations have to occur after all checks but before any interactions . This pattern, often referred to as optimistic accounting, ensures that state variables are updated before performing any external interactions.
Transactions involving accounts on different shards require inter-shard messaging and coordination, which adds computational overhead and delays transaction finality. In the past, this has led to downtime on such blockchains, as was the case for. Objects can be processed and managed separately without requiring global state synchronization, and multiple transactions can be processed concurrently without the need for synchronization across shards.
Using linear logic and capability-based security ensures robust resource management and access control, potentially lowering the risk of errors and security vulnerabilities. Additionally, Sui’s approach to managing complex assets, such as NFTs, simplifies interactions and improves efficiency compared to traditional account-based models. These features position Sui as a noteworthy advancement in blockchain technology.
