Aptos vs Sui: A Battle Of The New-Generation Layer-1 Blockchain

Aptos vs Sui: A Battle Of The New-Generation Layer-1 Blockchain
Aptos vs Sui

The growth of Layer 1 blockchains over the past year has been undeniable, with numerous new L1 platforms emerging. It can be viewed as an alternate blockchain to Ethereum, the original and most widely used one. The recent Solana and Nomad hacks have made a more secure blockchain more important than ever to investors and developers. Aptos vs Sui, two emerging Layer 1 platforms, attracted the interest of venture capitalists and IT enthusiasts (VC). We'll examine and contrast Aptos vs Sui blockchain in this essay to determine which Layer-1 platform is superior.

What Is Sui Blockchain?

Sui is a permissionless, PoS-powered Layer 1 blockchain that aims to provide instantaneous settlement and high throughput while also enabling a wide range of latency-sensitive, future-proof decentralized applications. Programmers can use it to create Web3 initiatives that will serve the expected massive influx of Web3 users.

Mysten Labs, the Web3 infrastructure company created by former senior executives from Meta's Novi Research, is supporting Sui. It is composed of specialists in distributed systems, programming languages, and cryptography.

What Is Aptos Blockchain?

On October 17th, Aptos Blockchain made its public debut following four years of development and millions of dollars in funding. It is the Layer 1 platform, which seeks to build the ideal blockchain by upholding decentralization, offering the highest level of security, and facilitating scalability, quick transaction times, and low transaction costs.

In order to develop a comprehensive blockchain solution that promotes the widespread usage of web3, it seeks to decentralize the cloud infrastructure that powers web2 in order to do so. The goal of the DApp ecosystem that Aptos Blockchain intends to build is to solve real-world issues.

Aptos vs Sui comparison

Aptos vs Sui Blockchain have some differences you should not miss when comparing.

Aptos vs Sui: Programming Language

Move, Sui programming language is used by both Sui and Aptos. Sui's implementation of Move, however, differs slightly from Aptos', which makes use of a version that is more like the initial iteration.

In essence, the Web3 programming language of the future is Move, a bytecode language used to create smart contracts and customized transactions on the blockchain network. Diem's white paper states that Move concentrates on access restriction and scarcity. In order to prevent double spending, scarcity limits the production of assets, whereas access control controls ownership and privileges.

The model is the primary factor that distinguishes the Move language of the Sui blockchain from the Aptos blockchain. While Aptos uses an address-centric approach, Sui's Move uses an object-centric one. Therefore, tokens, smart contracts, and NFTs will be shown as "things" on the screen. Contrarily, Aptos collaborates closely with the majority of blockchain networks, where the majority of activity included updating address-related data. The network must update with two ledgers in order for this mechanism to work, one for senders and one for recipients. Most transfers only require a single update to the ledger since nearly all on-chain transactions change the data associated with each object. In contrast to Aptos, Sui's version of Move is explicit about whether an object is owned, shared, mutable, or immutable.

Aptos vs Sui: Architecture

Aptos makes use of parallelization by dynamically recognizing dependencies and allocating execution tasks using BlockSTM, a variant of the HotStuff consensus mechanism.

Aptos makes advantage of the improved BFT consensus protocol known as HotStuff. Diem modified it to produce DiemBFT, which Aptos later improved under the name AptosBFT. The key ideas of the Aptos consensus are as follows:

  • AptosBFT: By evaluating on-chain states and automatically updating validators to fix unqualified validators without human intervention, it keeps the network decentralized. The BFT system can continue work even if certain nodes fail.
  • Aptos Block-STM: Aptos is able to process up to 160,000 transactions per second thanks to this mechanism. The dependencies between transactions are also established by Block-STM, so if one cannot be validated, the procedures that depend on it will be repeated.

As its consensus technique for parallelization at the execution layer, Sui implements Narwhal and Tusk. Due to the asynchronous nature of the protocol, it is resistant to DoS (denial of service) assaults.

  • Narwhal: is responsible for ensuring that transaction data is accessible, which is the mempool module.
  • Tusk: is the consensus module that prioritizes the submitted transactions for consensus (for complex transactions).

Aptos vs Sui: Tokenomics

Aptos tokenomics

With a 1 billion token initial supply, APT is the native token of Aptos. 82% of the initial supply is currently staked for Proof of Staking (PoS) participation across all categories below, according to Aptos Labs.

  • 51.02% will be distributed to the community (10-year vesting period)
  • 19.00% will be distributed to core contributors (4-year vesting period)
  • 16.50% will be distributed to the Aptos Foundation (10-year vesting period)
  • 13.48% will be distributed to the project’s investors (4-year vesting period)

Sui tokenomics

On the other side, Mysten Labs produced a comprehensive whitepaper for their native coin, SUI. A fixed supply of 10 billion tokens exists. At the start of each Sui era, holders of Sui delegate their tokens to validators, and a new validation committee is established.

As a result, SUI, the network's native coin, will mostly be used for the following purposes:

  • Gas fees: Gas fees are paid to participants in the Proof of Stake process. Additionally, it can be utilized to defend against spam and denial-of-service assaults.
  • Storage Fund: In order to reimburse future validators for the costs associated with on-chain data storage, Sui's store is utilized to gradually disperse stake incentives to validators.
  • Proof-of-stake Mechanism: Platform operators, also known as validators and delegators, are chosen, motivated, and rewarded using this method.
  • On-chain voting: To cast votes on matters regarding protocol and governance changes.
  • Sui also has a system for calculating gas prices that keeps costs down and is predictable.

Final Thought - Aptos vs Sui: Which Layer1 Platform Is Superior?

Right now, it's difficult to say which Layer1 platform is superior because Aptos and Sui are both two distinctive and ambitious L1 projects created by qualified teams with in-depth technical and product understanding.

Sui's novel approach to blockchains and object-centric architecture provides a novel viewpoint on the L1 space. We'll also monitor Aptos' "upgradability" to see how it functions.
