Core Architecture and Consensus Mechanism

Object-Centric Data Model

Unlike traditional blockchain systems that use account-based models, Sui employs an object-centric data model. This model treats every asset as a distinct, mutable object that can be owned, transferred, or modified independently. Such an approach improves scalability by allowing for parallel processing of transactions that affect different objects concurrently.

Key advantages of the object-centric approach include:

• Parallel Execution: Transactions that affect non-overlapping objects can be processed in parallel, reducing bottlenecks.
• Fine-Grained State Management: Developers can work with discrete objects, leading to better optimization and resource utilization.
• Enhanced Security: Isolated objects reduce the risk of cascading failures, as a fault in one object does not necessarily affect others.

Consensus Protocol

Sui's consensus mechanism is designed to be both fast and secure. It utilizes a combination of techniques tailored to handle the object-centric data model efficiently:

• Byzantine Fault Tolerance (BFT): Sui integrates a Byzantine Fault Tolerant consensus mechanism to ensure that the network remains secure and operational even if some nodes act maliciously or fail.
• Asynchronous Processing: To facilitate rapid confirmation of transactions, Sui allows asynchronous processing of independent transactions, thereby improving overall throughput.
• Scalability through Sharding: Although not sharding in the traditional sense, Sui's architecture allows for horizontal scaling by partitioning the state space into independently manageable objects.

The consensus mechanism is optimized to resolve conflicts and ensure data consistency, even when multiple transactions interact with the same object. This is achieved through rigorous validation rules and conflict resolution strategies that are built into the protocol.
