Sui stores data as individual objects instead of tracking account balances, separating it from Ethereum, Solana, and most other blockchains. Each object carries its own ID, owner, and version history, letting the network process unrelated transactions at once instead of running everything through one shared ledger state.
How Is Sui’s Object Model Different From Account-Based Blockchains?
Ethereum and Solana use an account-based model, where the ledger tracks a balance tied to each wallet address. Every transaction touches that shared state, so the network processes transactions in strict order to avoid conflicts.
Sui, built by Mysten Labs and launched on mainnet in May 2023, treats every asset, from a coin to an NFT to a smart contract package, as a distinct object with its own unique ID. Objects can be owned by one address, shared among multiple users, or marked immutable so no one can change them again.
How Does Sui Enable Parallel Transaction Processing?
Because objects are independent by default, Sui can run transactions touching different objects at the same time instead of lining them up one after another:
- A payment moving one owned object between two addresses does not need network-wide consensus.
- Simple transfers can bypass full consensus and settle in under a second.
- Shared-object transactions, like a DeFi pool multiple users interact with, require Byzantine Fault Tolerant consensus through Sui’s Mysticeti protocol.
- Programmable Transaction Blocks let developers bundle up to 1,024 actions into one atomic transaction.
Sui also uses Move rather than Solidity, a language built around the same asset-representation logic as the object model that removes bug classes causing exploits elsewhere.
Why This Matters For Everyday Users
The practical effect is speed. A wallet-to-wallet transfer clears almost instantly, while an action touching a shared resource still waits for network agreement, similar to other chains.
How Does Sui’s Storage Fund Pay For Data Long-Term?
Sui prices storage differently than chains treating it as a one-time fee. Creating an object costs a fee upfront, split into a refundable deposit and a non-refundable portion, currently 1 percent, permanently removed from circulation.
The refundable share sits in a storage fund until the object is deleted or shrunk, when up to 99 percent returns to whoever performed that transaction, even if they were not the original creator. The rebate exists because today’s validators are not the ones who will store data years from now.
Where Does Walrus Fit Into Sui’s Storage Strategy?
On-chain objects suit account state and application logic, but not large files like images or AI training data. Walrus, a separate storage protocol also built by Mysten Labs, splits large files into encoded pieces distributed across storage nodes and referenced through the Sui ledger for verification.
Where Does $SUI Stand Today?
As of mid-July 2026, $SUI trades near $0.75, with a market cap around $3.0 billion, down roughly 86 percent from its all-time high of $5.35 in January 2025.
A CoinStats analysis from late June 2026 estimated Sui’s annualized network fee revenue at approximately $15 million, well below Ethereum and Solana’s totals above $500 million each, and put monthly active user growth at roughly 10 million to 40 million this year, though that pairing comes from a single research source rather than multiple trackers.
Analyst Michaël van de Poppe recently named $SUI among his top altcoin picks, citing early recovery signs.
The Bottom Line
Sui’s object-centric model processes unrelated transactions in parallel, settles simple transfers in under a second, and charges a storage fee that partially refunds itself when data is deleted.
Shared objects still rely on consensus, and large files route through Walrus instead of staying fully on-chain. Together, these give Sui a genuinely different foundation for on-chain data than account-based blockchains.
