TLDR:
- Sui finalizes independent transactions in 0.4–0.5 seconds using an object-centric parallel execution model.
- Near’s dynamic sharding allows the network itself to expand capacity as on-chain demand increases over time.
- Stablecoins make up 40–50% of Sui’s DeFi activity, with total DeFi value surpassing $2 billion in 2025.
- Near’s Confidential Intents launched in early 2026, enabling private cross-chain execution and AI-agent automation.
Sui and Near are two blockchain networks that both promise high throughput, low fees, and horizontal scalability. They are often grouped as competitors in the same category.
However, their underlying architectures reflect very different assumptions about how blockchain demand will grow.
Those architectural differences determine what type of activity each network can sustainably support. Understanding these differences helps investors and developers make more informed decisions about where to build or allocate capital.
Architecture and Throughput: Where the Two Networks Diverge
Sui is built around an object-centric model that treats assets as independent objects. When two transactions do not touch the same object, they skip full consensus and execute in parallel.
Only transactions involving shared objects enter the full consensus path. This design allows simple transfers to finalize in the 0.4 to 0.5 second range. As hardware improves, execution capacity on Sui scales accordingly.
Near takes a different structural approach by partitioning the network itself through sharding. State is split across shards, and validators are assigned to specific shard segments.
The protocol can dynamically reshard as demand increases, and finality typically lands between 0.6 and 1.3 seconds.
Developers on Near interact with a protocol that manages scaling internally, reducing the need to handle partition logic manually.
In real-time conditions, neither network is currently constrained by throughput. Observed TPS on Sui ranges around the mid-20s, while Near operates between 30 and 40.
Both chains advertise theoretical ceilings far beyond current usage. The bottleneck today is demand, not execution capacity.
Crypto analyst eye zen hour, who requested a deep dive into both networks, noted that the competitive lens has shifted toward cost efficiency, liquidity depth, and ecosystem traction rather than raw TPS claims. That shift reflects where actual network value accumulates in the current market environment.
Validator design also differs between the two. Sui requires higher hardware specifications and greater stake exposure, creating a performance-oriented validator set.
Near lowers entry barriers through dynamic seat pricing and lighter hardware requirements, distributing workload across shards and broadening validator participation.
Stablecoins and Privacy: Competing Strategies for Institutional Growth
Stablecoins represent a practical stress test for any blockchain network. They simultaneously test settlement speed, liquidity routing, composability, and compliance readiness.
On Sui, stablecoins now account for roughly 40 to 50 percent of DeFi activity, with total DeFi value surpassing $2 billion in 2025.
Assets such as USDsui, suiUSDe, BlackRock-backed USDi, and over-collateralized BUCK reflect a strategy built around high-velocity settlement within a single execution environment. Zero-fee stablecoin transfers are planned for 2026.
Near’s stablecoin strategy focuses on liquidity mobility across multiple environments. USDC and USDT operate under the NEP-141 standard, and the Stablecoin Transport Protocol enables efficient cross-chain routing.
Cross-chain volume through Near Intents surpassed $13 billion in 2025, positioning stablecoins as cross-chain coordination tools rather than purely local settlement assets.
On privacy, Sui currently offers pseudonymity and object-level isolation. Its 2026 roadmap includes protocol-level default privacy through zero-knowledge proofs, homomorphic encryption, and selective disclosure.
Near, on the other hand, already launched Confidential Accounts and Confidential Intents in early 2026, enabling private cross-chain execution and AI-agent automation today.
Near’s active deployment of privacy features contrasts with Sui’s roadmap-based approach. Both paths are coherent, but Near’s execution-layer confidentiality is currently live, while Sui’s embedded privacy remains in development.
Market positioning further separates the two. Sui has established traction in gaming, consumer payments, storage, and institutional products.
Near centers its narrative on AI-native infrastructure, cross-chain coordination, and developer accessibility through JavaScript tooling and intent-based architecture. Both are viable, and adoption distribution over the next cycle will ultimately determine which scaling assumption proves more durable.
