The surge of SUI past $3.50 has reignited interest in Move-powered blockchains. As one of the fastest-growing ecosystems in Web3, the so-called “Move chains” — Sui, Aptos, and Movement — are increasingly drawing attention from developers, investors, and crypto enthusiasts alike. While all three support smart contracts written in the Move programming language, their technical designs, user experiences, and ecosystem strategies differ significantly.
In this deep dive, we’ll explore what sets these platforms apart beyond surface-level comparisons, helping you understand which might best align with your development goals or investment thesis.
What Are Move-Based Blockchains?
Move is a programming language originally developed for Facebook’s (now Meta) defunct Libra/Diem project. Designed with security and resource-oriented programming in mind, Move prevents common vulnerabilities like reentrancy attacks by treating digital assets as unique, non-copyable objects.
Today, Sui, Aptos, and Movement have evolved from this foundation into distinct blockchain platforms:
- Sui and Aptos: Layer 1 blockchains developed by former Diem team members.
- Movement: A Layer 2 solution bringing Move to Ethereum.
Despite sharing a common origin, each chain has taken a different path in architecture, consensus, and ecosystem development.

Technical Architecture: DAG vs Linear Chain
One of the most misunderstood aspects of Move chains is their underlying data structure.
Sui and Aptos: Directed Acyclic Graph (DAG)
Contrary to popular belief, Sui and Aptos are not traditional blockchains. Instead, they use a Directed Acyclic Graph (DAG) model where transactions form a web of interdependent nodes rather than being grouped into linear blocks.
This allows for parallel transaction processing, drastically improving throughput. For example:
- Sui uses an object-centric DAG model, enabling high-speed execution when transactions don’t conflict.
- Aptos initially launched as a linear chain but later adopted DAG to enhance scalability.
Note: Some analyses incorrectly label Aptos as a linear blockchain — a misconception that highlights the need for deeper technical literacy in the space.
Movement: Ethereum-Aligned Layer 2
In contrast, Movement follows a more conventional linear blockchain structure built on Ethereum using zk-rollup technology. It leverages the Snowman consensus (from Avalanche) and focuses on integrating Move into the Ethereum ecosystem.
This makes Movement more compatible with existing Ethereum tooling while still benefiting from Move’s safety guarantees.
Consensus & Performance Comparison
Performance metrics like transaction finality time (TTF) and throughput vary across the three chains due to different consensus mechanisms.
| Chain | Consensus Mechanism | TTF (Typical) | Parallel Execution Engine |
|---|---|---|---|
| Sui | Mysticeti (BFT + DAG) | ~0.5 seconds | State access-based sorting |
| Aptos | AptosBFT → RAPTR (upcoming) | ~1 second | Block-STM (optimistic) |
| Movement | Snowman | ~1 second | Block-STM |
- Sui’s Mysticeti currently offers the fastest confirmation times.
- Aptos relies on Block-STM, an optimistic parallel execution engine now adopted by major projects like Starknet and Polygon.
- Movement also uses Block-STM, making it easier for developers familiar with Aptos to transition.

User Experience: Speed, Cost, and Stability
Let’s shift from theory to real-world usage.
Transaction Speed & Fees
All three chains offer near-instant interactions under normal conditions. However, fee structures differ:
- Aptos: Consistently low gas fees across all operations — often less than $0.01.
- Sui: Generally fast, but certain actions (e.g., claiming rewards on Navi) can cost over $0.10 due to computational intensity or suboptimal contract design.
- Movement: Still in testnet; fee model will be influenced by Ethereum L1 costs.
From a cost-efficiency standpoint, Aptos currently leads for frequent users.
Network Stability
Reliability matters — especially for financial applications.
- Sui: No network outages since mainnet launch. Successfully handled high-volume events like NFT mints and memecoin surges.
- Aptos: Experienced a brief halt in block production in October 2023, raising concerns about resilience during stress periods.
While both are robust, Sui’s uptime record gives it an edge for mission-critical dApps.
Wallet & Hardware Support: A Critical Differentiator
Security-conscious users rely on hardware wallets like Ledger.
Here’s where a major gap emerges:
Sui Wallet:
- Poor Ledger integration.
- Requires manual blind signing setup.
- No support in popular mobile wallets (e.g., Ethos, Tao).
Aptos (Petra Wallet):
- Full Ledger support with regular firmware updates.
- Smooth UX with animated confirmations and multi-account management.
The Petra wallet delivers a polished experience that reflects Aptos’ focus on user-centric design.
Sui appears to prioritize mass adoption via social logins (Google, Facebook), targeting Web2 users. In contrast, Aptos caters more directly to crypto-native users, investing heavily in developer and wallet tooling.
Team Philosophy & Ecosystem Strategy
Innovation vs Adoption
- Sui (Mysten Labs): Emphasizes innovation — from DAG architecture to Walrus (decentralized storage) and offline radio-based transactions.
- Aptos: Often seen as following Sui’s lead — adopting object models and later launching similar incentive programs.
- Movement: Focuses on community hype and momentum. Despite no mainnet yet, it boasts over 60 apps and millions of testnet addresses.
Interestingly:
- Sui did not offer testnet airdrops but ran lottery-based token sales.
- Aptos provided generous testnet incentives — many users’ “first crypto win.”
- Movement has built a cult-like following with slogans like “gmove,” despite no token yet.
Ecosystem Maturity & Community Engagement
As of 2025:
- Sui’s ecosystem leads in DeFi TVL and project diversity.
- Aptos’ growth has been fueled largely by foundation-backed lending protocols offering APT incentives.
- Movement’s testnet activity is impressive — over 60 projects deployed and strong community engagement.
Yet both Sui and Aptos face criticism over lack of retail-friendly wealth creation:
- No major memecoins or surprise airdrops like Solana’s BONK or JTO.
- Sui’s Navi protocol promised key role for points in future airdrop — but never delivered after token launch.
Meanwhile:
- Sui’s own projects (e.g., Deepbook, Sui Name Service) have distributed tokens widely.
- Many Aptos dApps remain unfunded — leaving room for future airdrop opportunities.
Frequently Asked Questions (FAQ)
Q: Are Sui and Aptos the same blockchain?
A: No. While both originated from Meta’s Diem project and use variants of the Move language, they differ in data structure (DAG), execution model, and ecosystem strategy.
Q: Can I use my Ledger with Sui?
A: Technically yes, but support is limited. You must enable blind signing manually, and most mobile wallets don’t support hardware integration — unlike Aptos’ Petra wallet.
Q: Which chain has better DeFi yields?
A: Currently, Aptos offers higher yields through foundation-subsidized lending apps. However, many lack long-term sustainability. Sui has more organic growth but fewer high-return opportunities.
Q: Is Movement better than Sui or Aptos?
A: Not yet. Movement is still on testnet. Its strength lies in community momentum and Ethereum compatibility, but real performance won’t be clear until mainnet launch.
Q: Will there be more airdrops on Aptos or Sui?
A: Aptos has higher potential — most major dApps haven’t launched tokens. On Sui, many projects have already issued tokens with minimal or no community airdrops.
Q: Why isn’t there a big memecoin on Sui or Aptos?
A: Both ecosystems lack viral culture seen on Solana. Sui’s largest memecoin is worth ~1/20th of WIF; Aptos’ GUI is even smaller. This could change as communities grow.
Final Thoughts: The Future of Move Chains
Despite differences, all three chains contribute to expanding the reach of the Move language:
- Sui pushes technical boundaries.
- Aptos builds enterprise-grade infrastructure.
- Movement bridges Move to Ethereum’s vast user base.
As modular blockchain design gains traction, these platforms may eventually complement rather than compete with each other.
