As blockchain adoption grows in 2025, platforms like NEAR, Aptos, and Sui stand out for their innovative VMs. These systems handle high throughput, low latency, and enhanced security with ease.
This article compares NEAR vs Aptos vs Sui, focusing on their modern VMs in a battle for superiority. Whether you’re a beginner exploring blockchain basics or a developer seeking insights into performance and scalability, we’ll break it down in simple terms. We use verified facts from reliable sources throughout this comparison.
These three Layer-1 blockchains address common pain points. Specifically, they solve slow transaction speeds and high fees seen in older networks like Ethereum. NEAR uses WebAssembly (WASM) for its VM. Meanwhile, Aptos and Sui leverage the Move VM with unique twists. By examining their architectures, features, and real-world performance, we can see how they stack up. This comparison is based on official documentation, benchmarks, and industry analyses to ensure accuracy.
What is a Blockchain Virtual Machine?
A blockchain virtual machine is essentially the “engine” that runs smart contracts. Think of it as a secure sandbox where programs operate without trusting any single party. VMs translate high-level code into machine-readable instructions. Consequently, transactions are processed consistently across all network nodes.
Traditional VMs, like Ethereum’s EVM, are stack-based and can be slow. This limitation affects scalability negatively. However, modern VMs optimize for speed and parallelism. As a result, multiple operations happen simultaneously. For beginners, imagine a VM as a universal translator. Developers write code in familiar languages, and the VM executes it efficiently on the blockchain.
Key benefits include:
- Security — preventing bugs like reentrancy attacks
- Performance — high transactions per second (TPS)
- Developer-friendliness — support for popular programming languages
In the NEAR vs Aptos vs Sui comparison, each VM brings unique strengths to these areas. Therefore, they’re ideal for DeFi, gaming, and NFTs. To understand how blockchain gaming works in practice, check out our guide on Ethereum gaming and how blockchain games actually work.
NEAR Protocol’s Virtual Machine: WebAssembly Powerhouse
NEAR Protocol, launched in 2020, uses a WebAssembly (WASM)-based VM. This design delivers high performance and accessibility. WASM is a stack-based virtual machine by design. It targets near-native speeds through a compact binary format and efficient JIT compilation pipeline. The WebAssembly specification details these technical aspects.
At its core, NEAR’s runtime compiles smart contracts written in languages like Rust or AssemblyScript into WASM bytecode. The VM enforces a gas model. Users pay for computation, storage, and bandwidth. This prevents spam and ensures fair usage.
Additionally, security is bolstered by WASM’s sandboxing. This isolates code execution and relies on correct implementation of the WASM security model. Features like function calls allow contracts to interact seamlessly. Furthermore, the VM supports dynamic module loading for better modularity.
Performance-wise, NEAR achieves low latency and high throughput through sharding. The Nightshade technology divides the network into smaller shards. Consequently, parallel processing becomes possible. In May 2025, NEAR publicly reported approximately 600 millisecond block times and 1.2 second user finality. These improvements followed Nightshade 2.0 optimizations.
For developers, NEAR offers tools like the NEAR CLI and SDKs. This lowers the entry barrier significantly. In fact, beginners can deploy a simple contract in minutes.
NEAR’s zkWASM capabilities come through an announced partnership with Polygon Labs. Together, they’re building a zkWASM prover for WASM chains. Polygon’s technology blog discusses this collaboration. Moreover, the project’s broader climate positioning includes carbon-neutral certifications. These are purchased via providers like South Pole, though this depends on periodic recertification.
Aptos’ Move Virtual Machine: Security-First Design
Aptos, founded by former Meta engineers, launched in 2022. It employs the Move VM, originally developed for the Diem project. Move is a resource-oriented language that treats digital assets as first-class citizens. Therefore, it prevents common errors like double-spending through static verification.
The Aptos Move VM uses a bytecode interpreter for execution. Its architecture focuses heavily on parallelism. It employs Block-STM (Software Transactional Memory) for optimistic concurrent execution. This detects conflicts dynamically and allows high TPS.
Peer-reviewed research and foundation posts document impressive numbers. Specifically, 110,000 to 170,000 TPS in controlled benchmarks. Additionally, a sustained approximately 20,000 TPS for 30 minutes in standardized setups. ACM Digital Library papers and Aptos Labs documentation detail these findings. Security features include formal verification of critical modules. There’s also a focus on modularity for upgradability.
Recent Aptos materials cite sub-second finality. Block times are well under 130 milliseconds. User finality clocks in at approximately 650 milliseconds. However, numbers depend on network conditions and measurement methods. Messari reports these performance metrics.
For beginners, Move’s syntax is straightforward. A simple token transfer script demonstrates resource ownership. Notably, there are no loops or recursion risks.
Developer experience is strong with tools like the Aptos CLI, Move Analyzer, and integration with Rust. Real-world adoption examples include EXPO 2025 Osaka’s Digital Wallet. Partners reported over 133,000 new accounts and approximately 558,000 transactions during the event period. This showcases consumer-facing throughput effectively. PR Newswire and the Laotian Times covered this deployment.

Sui’s Move Virtual Machine: Object-Centric Innovation
Sui, also stemming from Diem alumni, went live in 2023. It adapts the Move VM with an object-centric data model. Unlike traditional account-based systems, Sui treats everything as objects with unique IDs. Consequently, this enables parallel execution by default. There’s no need for sequential processing unless objects overlap. Sui’s official documentation explains this architecture.
The VM uses Narwhal/Bullshark-family DAG consensus. In 2024–2025, Sui rolled out Mysticeti, a low-latency variant. It demonstrated approximately 500 millisecond commit latency in WAN tests. Additionally, sub-second latency in research results. Meanwhile, it sustains high throughput under load. The Sui Blog documents these achievements. This means strong horizontal scalability rather than literal “infinite TPS.”
On security, Sui leverages Move’s verification and additional tooling. However, 2025 saw several notable third-party protocol exploits on Sui. These included Cetus (approximately $220–223 million in May 2025), Nemo (approximately $2.4 million in September 2025), and Typus (approximately $3.4 million in October 2025).
In response, the Sui Foundation announced an ecosystem-wide $10 million security initiative. This funds monitoring, audits, and shared defenses. The Sui Blog, Cointelegraph, and The Block reported these developments.
For performance, Sui excels in gaming and NFTs. Independent transactions dominate these use cases. The platform offers sub-second finality and low fees. Beginners can grasp the object model through examples like NFT minting. Objects are created and transferred without global state locks. For more on NFT economics, explore our guide on NFT royalties in 2025.
Developer tools include Sui CLI, Move packages, and Rust support. These foster rapid iteration. On adoption metrics, public dashboards and reports show TVL crossing approximately $2 billion in October 2025. It peaked around $2.6 billion per DeFiLlama-based coverage. Meanwhile, daily active addresses have varied widely in 2025. Phemex analysis shows this variability. Point estimates should be treated cautiously due to measurement differences.
