Sui operates through a series of unique features such as horizontal scaling, composability, sparse replay, and on-chain storage. In the Sui network, each group of transactions is processed in parallel, eliminating the bottlenecking that occurs in some earlier blockchains. Sui's object-centric approach allows for more complex data structures and the ability to store assets inside such structures. Sparse replay means that game builders, for example, don't need to track transactions interacting with unrelated dApps, making querying on-chain data less expensive. Lastly, because assets are directly stored as objects on the Sui blockchain, they are never subject to Merkle tree indexing, making it cheaper to directly update assets on-chain.
