The blockchain landscape continues to evolve at a rapid pace, with new Layer 1 platforms pushing the boundaries of scalability, security, and developer experience. Among the most talked-about contenders are Sui, Aptos, and Cardano—three networks with distinct technical foundations, philosophies, and growth trajectories. While they all aim to address the limitations of early blockchains like Ethereum, their approaches differ significantly.
This deep dive explores how Sui has recently surged ahead in key metrics such as Total Value Locked (TVL) and transaction throughput, how it compares to Aptos in architecture and performance, and where Cardano stands in this competitive race. We’ll also examine real-world adoption trends, developer activity, and what these indicators mean for the future of decentralized applications.
Sui’s Surge in Adoption and Performance
In December 2023, Sui blockchain achieved a remarkable milestone by reaching a peak of 6,000 transactions per second (TPS)—processing an astonishing 13.8 million blocks in a single day. This level of throughput is rare among Layer 1 networks and positions Sui as one of the fastest-growing ecosystems in Web3.
According to data from DefiLlama, Sui’s Total Value Locked (TVL) now exceeds $593 million**, more than doubling from $211 million at the start of the year. This surge places Sui ahead of established players like Cardano, Near Protocol, and even its close competitor Aptos** in terms of capital inflow and protocol engagement.
One major driver behind this growth is cross-chain liquidity. Over the past 30 days alone, $310 million worth of assets have been bridged from Ethereum to Sui via Wormhole, indicating strong investor confidence and growing demand for high-performance DeFi solutions.

Technical Edge: The Move Language Advantage
Sui shares a foundational trait with Aptos—they both use Move, a programming language originally developed by former Meta (formerly Facebook) engineers for the now-defunct Diem (Libra) project. Move emphasizes resource-oriented programming, enhancing security by treating digital assets as first-class citizens that cannot be duplicated or accidentally deleted.
However, Sui differentiates itself through its object-centric model and parallel execution engine. Unlike traditional account-based models, Sui treats every piece of data as an individual object with its own ownership rules. This allows transactions affecting separate objects to be processed simultaneously, drastically improving speed and efficiency.
In contrast, most blockchains—including Ethereum and even Cardano—process transactions sequentially, creating bottlenecks during high network usage.
Aptos: A Strong Contender with Similar Roots
Aptos also leverages the Move language and targets high scalability, aiming to support thousands of TPS. It too benefits from a team with deep roots in Meta’s Diem project. However, despite technical similarities, Aptos has not seen the same momentum as Sui in recent months.
While Aptos maintains a solid developer base and several active DeFi protocols, its TVL remains below Sui’s. One possible reason lies in ecosystem incentives and timing. Sui gained visibility through a successful launch on Binance Launchpad, which brought immediate exposure and liquidity. Although Aptos had a strong initial reception, sustained user acquisition and protocol innovation have favored Sui lately.
Additionally, Sui’s focus on NFTs and on-chain data inscription—inspired by Bitcoin’s Ordinals movement—has attracted a new wave of creators and speculators. By enabling users to inscribe arbitrary data directly onto the blockchain without requiring smart contracts, Sui opened up novel use cases beyond finance.
Cardano: The Academic Approach in a Speed-Driven Market
Cardano takes a fundamentally different path. Developed by Charles Hoskinson, co-founder of Ethereum, Cardano emphasizes peer-reviewed research, formal verification, and long-term sustainability over raw performance.
Built using Haskell—a highly secure functional programming language—Cardano prioritizes correctness and reliability. Its consensus mechanism, Ouroboros, is mathematically proven secure and energy-efficient. However, these strengths come at a cost: lower transaction speeds and slower development cycles compared to Sui or Aptos.
As of early 2025, Cardano supports smart contracts but lags behind in DeFi adoption. Its TVL remains relatively modest, reflecting challenges in attracting developers and liquidity despite its robust theoretical foundation.
While Cardano excels in identity solutions (e.g., Atala PRISM) and sustainability-focused projects, it struggles to compete with the agility and throughput of newer Layer 1s in fast-moving markets like DeFi and NFTs.

Developer Momentum and Ecosystem Growth
Ecosystem vitality depends not just on technology but on developer engagement. Sui has made significant strides here:
- The two largest protocols on Sui—Scallop Lend and Navi Protocol—have seen their TVL grow fourfold since the beginning of the year.
- Multiple grant programs and hackathons have fueled innovation.
- Tools like Sui Studio and Move Playground lower the barrier to entry for new developers.
In contrast, Cardano’s development environment is often criticized for being complex and slow to iterate. While Plutus Script offers powerful capabilities, it requires specialized knowledge that limits broader participation.
Aptos maintains a healthy SDK ecosystem and strong documentation but hasn’t matched Sui’s recent burst in application-level innovation.
Frequently Asked Questions (FAQ)
Q: Why is Sui faster than other blockchains?
A: Sui uses an object-centric data model and parallel transaction processing powered by its Narwhal & Tusk consensus mechanism. This allows it to scale horizontally and handle thousands of TPS efficiently.
Q: Are Sui and Aptos the same since they both use Move?
A: While both use the Move programming language, their architectural designs differ significantly. Sui focuses on object ownership and parallel execution; Aptos uses a more traditional account model with sequential processing optimizations.
Q: Can Cardano catch up to Sui in DeFi?
A: It’s possible over time, but Cardano would need to accelerate smart contract tooling improvements, attract more developers, and launch compelling incentive programs to boost liquidity.
Q: Is high TPS enough for long-term success?
A: Not alone. While speed is critical for user experience, long-term success also depends on decentralization, security, developer support, and real-world utility beyond speculation.
Q: What risks are associated with newer blockchains like Sui?
A: Newer networks face risks around validator centralization, untested codebases under extreme load, and reliance on short-term hype. However, ongoing audits and community governance help mitigate these concerns.
Looking Ahead: What’s Next for These Platforms?
Sui’s recent performance suggests it's well-positioned to become a leading infrastructure layer for next-generation applications. Its blend of speed, innovative data handling, and growing ecosystem gives it an edge in attracting both users and capital.
Aptos remains technically sound but must accelerate ecosystem development to maintain relevance. Meanwhile, Cardano’s methodical approach may appeal to institutions and regulated environments but risks falling behind in consumer-facing Web3 innovation.
Ultimately, the future may not be about one chain dominating all others—but rather about specialization. High-speed chains like Sui could power real-time applications (gaming, social media), while academically rigorous platforms like Cardano serve identity and compliance needs.

Final Thoughts
The race among Layer 1 blockchains is far from over. Sui, Aptos, and Cardano each represent different visions for the future of decentralized systems:
- Sui: Speed-first innovation with Move-powered parallel execution.
- Aptos: Scalable infrastructure rooted in Diem-era engineering.
- Cardano: Security-through-formality with academic rigor.
For developers and investors alike, understanding these distinctions is crucial. As adoption grows and use cases diversify, the winners will be those platforms that balance performance with sustainability—and deliver real value to end users.
