When it comes to choosing the right blockchain technology, a lot of features and factors must be considered.
In this article, we will explore the similarities and differences between Sui and Aptos blockchains, delving into various aspects such as programming language, consensus mechanism, architecture, security, privacy, ecosystem, scalability, tokenomics, and funding. By the end of this article, you will have a clearer understanding of which blockchain suits your needs best.
The Similarities of Aptos and Sui
Both Aptos and Sui blockchains are designed to address the scalability and efficiency issues faced by the current generation of blockchain networks. They both implement one of the most advanced programming languages – Move, utilize parallel execution for high throughput (TPS), and offer low latency. These similarities make them attractive options for businesses looking to build blockchain-based applications.

Aptos vs. Sui: Detailed Comparison
The language used for parallel execution in both Aptos and Sui is Move, which is based on Rust and was initially designed at Meta. The language offers powerful tools and features to build smart contracts and decentralized applications. However, Sui has its own version of the language.
Aptos follows the standard design outlined in Diem’s whitepaper, while Sui has a slightly different object model. Sui’s storage system is object-centric, which means that most things on the blockchain, including addresses and transactions, are represented as objects.
Sui’s version of Move clearly indicates when an object is owned, shared, mutable, or immutable, whereas Aptos does not. Additionally, Sui’s ownership API is cleaner than Aptos’s, as it provides a clearer representation of the blockchain design.
Sui and Aptos have different architectures that affect how they use distributed ledger technology. Aptos uses a blockchain to record its ledger, while Sui’s distributed ledger is a directed acyclic graph. This impacts their consensus mechanisms and scalability.
Aptos utilizes a variant of the Proof of Stake (PoS) consensus mechanism called Byzantine Fault Tolerance (BFT), which ensures high network security and fast transaction confirmations. Sui, on the other hand, employs a novel consensus mechanism called Delegated Proof of Stake (DPoS), which emphasizes energy efficiency and decentralization. Sui uses an asynchronous consensus protocol called Narwhal and Bullshark, which allows for parallel execution of transactions.
Sui and Aptos differ significantly in their architecture, particularly in how they utilize distributed ledger technology. Sui’s ledger is stored as a directed acyclic graph (DAG) rather than a blockchain like Aptos. While both designs are efficient and share similarities with traditional blockchains, their differences are essential to their consensus mechanism and scalability.
Aptos has a modular architecture that enables easy upgrades and customizations, while Sui focuses on a multi-layered architecture to separate the consensus, storage, and computation layers. This allows for improved scalability and flexibility in the network.
Security and Privacy
While it is true that Aptos and Sui have not undergone a formal audit, this does not necessarily mean that they are not secure or reliable. Many blockchain projects have been successfully launched without formal audits, and smaller projects are not uncommon to prioritize other aspects of development before seeking formal auditing.
However, it’s important to acknowledge that potential vulnerabilities or flaws in the code may not be identified without a formal audit. It’s also worth noting that the lack of a formal audit could be a cause for concern for some investors and users who prioritize security and transparency. At Blaize, we provide deep security audit services for blockchains (nodes and consensus).
While Move programming language offers a significant level of security by its design, it doesn’t make contracts secure by default. Secure contract development includes using modern language features while crafting the code and secure and reliable architectural design of the contract with obligatory smart contract security audit.
The ecosystems are very different and extensive in both projects. Every day there is something new to discover at both chains. It’s hard to pick out an outsider and a favorite. Aptos blockchain got its popularity before Sui, but at the moment, judging by the number of followers on Discord, Sui is overtaking Aptos.
After a surge in the popularity of Aptos several months ago, many various projects were created and launched exactly using that blockchain. During the year 2022, over 100 projects were developed using Aptos network.
Aptos boasts a growing ecosystem of tools, libraries, and developer resources, while Sui’s ecosystem is relatively nascent but has the potential to grow rapidly as more developers join the network.
As for Sui, the mainnet of the network will only be launched in Q2 2023 and the testnet was launched in the last days of March 2023. Thus, the majority of the project is now TBA. One of the most remarkable Sui projects so far is Sui wallet. Still, the Sui blockchain has great potential to overtake Aptos due to its scalability level.
Aptos and Sui both focus on achieving high scalability through parallel execution, sharding, and other techniques, aiming to support millions of transactions per second.
Instead of relying on a centralized validator or pursuing large-scale decentralization, both Sui and Aptos prioritize optimizing scalability by maximizing network capacity, similar to the approach taken by Solana. However, the bottleneck in achieving this goal is likely to be the growth of the ecosystem’s state.
To address this bottleneck, Aptos prioritizes using heterogeneous validators with constrained CPU and storage resources, while Sui plans to efficiently shard data storage and scale its resources horizontally.
Aptos and Sui are two blockchain ecosystems with different approaches to their tokenomics. Aptos has released an overview of their tokenomics for their native token APT, but additional information is expected to be published soon. APT is currently used for PoS participation and liquidity incentives, with an initial supply of 1 billion tokens. The majority of the initial supply is currently staked for PoS participation, with the remaining tokens allocated to different categories.
On the other hand, Mysten Labs has published an in-depth whitepaper on the native token of Sui, SUI. SUI will be staked within an epoch to participate in the proof-of-stake mechanism and on-chain voting. Additionally, SUI will be used as the asset denomination to pay for gas fees and other operations on the Sui platform, with a total supply of 10 billion tokens. The exact allocation percentages for the distribution of tokens have not been released, but the presence of the storage fund can create monetary dynamics and reduce the amount of SUI in circulation.
Aptos Labs has amassed a total of about $400 million in funding from a wide array of capital ventures, including Andreessen Horowitz, FTX Ventures, Jump Crypto, a16z, Tiger Global, and Multicoin Capital, among others. At present, Aptos Labs counts 28 investors among its backers.
Meanwhile, Sui is making significant strides with its latest funding round, the Series B, which took place in September 2022. The company behind Sui, Mysten Labs, has received significant support from major investors, such as Lightspeed Venture Partners, Andreessen Horowitz, and Redpoint and managed to secure $300 million in this funding round, bringing Sui’s total funding to $36 million when combined with the $336 million raised in the Series A. Sui has also announced that it currently holds a valuation of over $2 billion.
