Vara vs Aptos, Monad, Sui, and Sei: A Technical Deep Dive into Data Parallelism

Introduction

After conducting extensive research, it's clear to me how blockchain technology has evolved. Originally developed as the foundation for cryptocurrencies, blockchain has become a highly adaptable platform with applications across various industries such as healthcare, supply chain management, finance, and more. Since its debut with Bitcoin in 2009, the introduction of smart contracts by Ethereum in 2015 was a significant milestone. Smart contracts enable programmable, self-executing agreements and address key limitations including scalability, storage, and interoperability.

Blockchain Technology Advancements

As blockchain technology became more widely adopted, early networks like Bitcoin and Ethereum began to demonstrate their limitations. These networks struggled to keep up with increasing demand, leading to issues with transaction speed, storage capacity, and inter-network communication. In response to these challenges, a new generation of blockchain projects has emerged, each offering a unique approach to overcome past shortcomings. Networks such as Vara, Aptos, Sei, Sui, and Monad have been designed to be faster, more scalable, and more interconnected than their predecessors.

At the time of writing, 20th September, 2024. Monad hasn’t launched it mainnet yet, but plan to do so this year.

Before we dive into the core of this article, we will compare several next-generation networks, specifically the Vara Network, Sui Network, Sei Network, Monad Network, and Aptos Network. We'll analyze these Layer-1 networks in terms of their TPS (transactions per second), throughput, distinctive features, scalability, and programming languages. Additionally, we'll explore the relationship between these Layer-1 networks and Layer-2 solutions, examining how Layer-2 technologies enhance scalability and performance.

However, since there is less publicly available information about Vara Network and its underlying Gear Protocol compared to the mentioned projects, I'll provide a more detailed introduction to both before delving into the technical comparison.

Gear Protocol: A closer look

The Gear Protocol is a big step forward in blockchain technology. It introduces a new way to develop and run smart contracts. At its heart, Gear combines the Actor Model and microservices principles. This allows for the creation of independent, simultaneous programs that communicate through message passing. This approach makes security stronger, simplifies memory management, and sets the stage for a more scalable and adaptable dApp ecosystem. Here are some key core concepts of the Gear Protocol:

1. Built-in Actors (BIAs): are specialized components within the Gear Protocol that execute specific business logic directly in the runtime. These BIAs allow smart contracts to access advanced blockchain features that typically require significant computational resources by managing core blockchain functions through pallets. By integrating these functions into the runtime, BIAs enhance the efficiency and capabilities of smart contracts using Gear.

   
   

2. Private State and Persistent Memory: Gear provides each program with its own private, isolated state (memory space) as opposed to the shared state model used by traditional blockchain platforms. This design improves security and simplifies memory management. Additionally, the introduction of persistent memory allows programs to maintain their intermediate state between function calls, leading to better computational efficiency and enabling more complex functionalities.

   
   

3. Parallel computations: Gear's isolated per-program memory enables message processing to be parallelized on validator nodes. This greatly improves the network's scalability and allows developers to introduce features that were not possible on serially computed smart contract platforms.

   
   

4. Self-Executing Programs and Continuous Automation: Gear enables programs to act as autonomous agents, allowing them to schedule future actions and execute themselves recursively. This self-executing nature drives innovation and facilitates the construction of complex, efficient, and autonomous dApps.

   
   

5. Gasless Transactions: Gear Protocol enables decentralized application (dApp) developers to allow end-users to interact with decentralized applications without needing the network's native tokens to pay gas fees, enhancing user participation and accessibility.

   
   

6. Signless Transactions: Gear's temporary trusted in-app sessions reduce the need for users to manually sign each transaction, streamlining the user experience and aligning it with expectations set by Web2 applications.

Vara Network

Vara Network operates as a decentralized, standalone, layer-1 blockchain network that allows developers to build and launch Web3.0 applications seamlessly. Powered by the Gear Protocol, it offers high speed and scalability, making it an excellent choice for creating and deploying next-generation Web3.0 decentralized applications (dApps).

Vara Network Features

Let's explore how Vara Network manifests the key concepts of Gear Protocol:

1. Actor Model and Microservices: Vara Network fully embraces Gear's actor-based architecture, allowing developers to create independent, concurrent programs that communicate via message passing. This implementation enhances scalability and modularity in decentralized applications (dApps) built on Vara.

   
   

2. Built-in Actors (BIAs): Vara incorporates BIAs as specified by Gear Protocol, enabling smart contracts to access advanced blockchain features directly within the runtime. This integration improves efficiency and expands the capabilities of dApps on the network.

   
   

3. Private State and Persistent Memory: In line with Gear's design, Vara provides each program with its own isolated memory space. This feature enhances security and simplifies state management for developers working on the Vara Network.

   
   

4. Parallel Computations: Vara leverages Gear's isolated memory model to enable parallel message processing, significantly boosting the network's throughput and scalability.

   
   

5. Self-Executing Programs and Automation: Vara implements Gear's concept of autonomous agents, allowing programs to schedule and execute future actions independently. This feature enables the creation of sophisticated, self-sustaining dApps on the network.

   
   

6. Gasless Transactions: Vara Network brings Gear's vision of gasless transactions to life, providing developers with tools to create user-friendly apps where end-users can interact without directly paying gas fees.

   
   

7. Signless Transactions: Vara implements Gear's approach to reducing transaction signing, and streamlining user interactions with dApps on the network.

The Relationship Between Gear Protocol and Vara Network

Vara Network is not an extension of Gear Protocol, but rather a live implementation of it. As a blockchain running the current Gear runtime, Vara Network showcases the practical application of Gear Protocol's features in a production environment with it own distintic features.

Gear Protocol and Vara Network have a close, interconnected relationship. Think of Gear as the architect who designs an innovative new type of building, complete with blueprints and specifications. Vara, on the other hand, is the actual building constructed based on those designs.

Gear provides the underlying technology, concepts, and rules for how a blockchain should work. It's the ideas and the theory. Vara Network takes all of these ideas and puts them into practice. It's a real, functioning blockchain that developers and users can interact with.

While Gear Protocol focuses on innovation and conceptual advancement, Vara is dedicated to real-world application and user experience. The distinction lies in this split between theory and practice, Gear pushes the boundaries of what's possible, and Vara makes these possibilities a reality. As Gear continues to evolve with new ideas, Vara implements them, while Vara's challenges help refine Gear’s future innovations. This dynamic exchange keeps both advancing in their respective roles, pushing blockchain technology forward.

Exploring the Actor Model and Built-in Actors

To further understand how Vara and Gear Protocol achieve scalability, parallel computation, and high transaction throughput, I believe it’s important to explore the Actor Model and the concept of Built-in Actors (BIAs) since each plays a critical role in enabling the modular, efficient, and autonomous behavior of decentralized applications (dApps) on these platforms,

Actor Model in Vara & Gear

An Actor Model is a mathematical model of concurrent computation that is used extensively in Gear Protocol. In this model, "actors" are the fundamental units of computation, which operate independently and interact by sending and receiving messages. This model facilitates parallel computation and scalability by ensuring that each actor handles its tasks in isolation, preventing conflicts and enhancing the efficiency of the system. As the core architecture for the Vara Network, the Actor Model enables Vara to scale effectively, leveraging the concurrency and parallelism inherent in the model to optimize network performance. The way this model achieves scalability and increases TPS is by distributing computational tasks across a network of independent actors.

Where each actor:

• Processes messages independently: By isolating the state and execution of each actor, the system avoids bottlenecks caused by shared memory or resource contention, allowing multiple tasks to be processed concurrently.

  
  

• Utilizes message-passing for communication: Actors interact via asynchronous message-passing, which is inherently non-blocking. This allows for high levels of concurrency, as actors can continue their operations while waiting for messages from other actors, effectively reducing idle time and maximizing system throughput.

  
  

• Enables parallel processing across cores: In a multi-core processing environment, actors are distributed across available cores, ensuring that all available computational resources are utilized efficiently. This division of labour increases the number of operations that can be handled in parallel, thus boosting the network’s transaction throughput.

When these properties of the Actor Model are leveraged, it ensures horizontal scalability as the number of actors (or smart contracts) increases. This allows the system to add more actors without restructuring, maintaining performance even as transaction demand grows.

I’ve written an in-depth article on the Vara/Gear actor model, you can find the link in the reference for more information.

Built-in Actor in Vara & Gear

The Built-in Actor in the Gear Protocol refers to pre-defined, fundamental components within the blockchain network that handle specific functionalities or services. These actors are integral to the operation of the blockchain and can interact with various programs or smart contracts, enabling them to access and utilize certain functionalities seamlessly.

Vara Network has implemented two key Built-in Actors (BIAs) to enhance its functionality: the staking BIA and the BLS12-381 cryptographic suite. The latter is noteworthy for its potential to optimize specific operations. BLS12-381 is available as a feature within the network’s architecture, enabling efficient native runtime calculations for complex cryptographic processes if required by dApps. This innovation tackles a common challenge in blockchain technology: the computational demands of certain cryptographic operations that can overwhelm traditional WebAssembly (Wasm) virtual machines. While BLS12-381 is an optional feature, it provides valuable functionality for developers needing enhanced performance for their applications.

By integrating the BLS12-381 BIA, Vara Network has devised a solution that offloads resource-heavy cryptographic tasks from the Wasm VM to a more efficient native runtime environment. This approach allows for the rapid execution of signature aggregation and verification processes. The implementation works by redirecting cryptographic method calls to a dedicated actor address, where the computations are performed off-chain in a native context. This method not only accelerates the processing speed but also substantially reduces the computational burden on the blockchain itself.

The benefits of this architectural decision are multifold. It circumvents the need for extensive on-chain calculations that could potentially consume numerous blocks and inflate gas costs. Moreover, it eliminates the necessity for complex algorithmic optimizations that would otherwise be required to partition these operations across multiple blocks. Consequently, the BLS12-381 BIA significantly enhances the overall efficiency of the Vara Network, enabling it to maintain high-performance standards while keeping operational costs in check.

Synergy Between Actor Model and BIAs For Performance

The combination of the Actor Model and Built-in Actors (BIAs) in the Vara Network creates a robust framework that ensures high scalability, increased transaction throughput (TPS), and optimized performance.

• Distributed workload: The Actor Model ensures that the system's computational workload is distributed across many actors, each operating independently. This modularity reduces the risk of bottlenecks and allows the network to handle increasing numbers of transactions as more actors are added.

  
  

• Efficient resource management: BIAs take on specialized tasks, allowing actors to focus on their core functions. This division of labor ensures that the network’s resources are used efficiently, leading to faster transaction processing and a higher TPS.

Conclusion: How Vara Network Achieves Scalability and Increased TPS

By combining the concurrency and parallelism of the Actor Model with the specialized efficiency of Built-In Actors (BIAs), the Vara Network achieves significant scalability and throughput. The Actor Model allows for distributed, non-blocking computation, while BIAs optimize performance by handling stalking. This synergy ensures that the network can scale horizontally, process more transactions per second, and maintain high-performance standards as it grows.

Great! Now that you understand how Vara Network achieves scalability, security, high transaction throughput, and parallel computations, it’s time to compare Vara, Aptos, Sui, Sei, and Monad networks against each other.

As blockchain technology moves towards mainstream adoption, reducing barriers to entry for end-users will become increasingly important. In this aspect, Vara seems to be ahead of the curve.

I believe that Vara's potential isn't just about its current features. The flexibility of its architecture, built on the Gear Protocol, suggests that Vara has significant room for future optimizations and upgrades. As the network grows and evolves, we might see improvements in areas like finality time, which could further boost its transaction throughput and expand its use cases.While Sei currently leads in total transactions and Monad boasts impressive testnet figures, Vara's balanced approach and room for growth make it a strong contender in the long run. As these networks continue to develop and real-world usage increases, Vara's combination of high performance and user-friendly features make it well-positioned to play a significant role in shaping the future of decentralized applications and blockchain technology as a whole.

In the next part of our discussion, after we explore how some of these layer-2 networks address these limitations, we'll delve deeper into Vara's prospects and developments, exploring how this AI integration could reshape the network's capabilities, its potential impact on the broader blockchain ecosystem, and the new horizons it might open for decentralized applications and services. The fusion of blockchain and AI in Vara's architecture could represent the next evolutionary step in distributed ledger technology.

Exploring Layer-2 Solution on Early Limitations

As we have observed, Layer-1 networks such as Bitcoin and Ethereum are facing significant scalability issues. This has led to the emergence of new Layer-1 solutions. However, efforts to overcome these limitations are not limited to Layer-1 advancements alone. Layer-2 networks have also been developed to improve the scalability and performance of existing blockchain networks while maintaining their security and decentralization. Keeping this in mind, let's explore three pioneering Layer-2 solutions within the Ethereum ecosystem: Lagrange, MegaEth, and RISC0. Similar to the Layer-1 networks discussed earlier, these solutions aim to address these critical challenges.

Lagrange

Lagrange is an advanced Layer-2 (L2) solution on Ethereum, leveraging zero-knowledge proofs (zk-SNARKs) to enable scalable and secure smart contract execution. The core concept of Lagrange revolves around decentralizing execution while ensuring verifiable outcomes. This is achieved through zk-SNARKs, which allow for the validation of computations without revealing the underlying data. One of the key advantages of Lagrange is its support for parallel computations, which significantly enhances the throughput and efficiency of the Ethereum network. By distributing the computational load across multiple nodes and verifying results using zk-SNARKs, Lagrange ensures that smart contracts can be executed at a scale far beyond what the Ethereum mainnet can handle. This capability is crucial for applications requiring high throughput, such as decentralized finance (DeFi) platforms and gaming ecosystems. Moreover, Lagrange maintains the security guarantees of Ethereum, as the computations are verifiable on-chain. This combination of scalability and security positions Lagrange as a powerful tool for developers looking to build complex, high-performance applications on Ethereum.

MegaEth

MegaEth is another L2 solution designed to enhance the scalability of Ethereum by using zk-rollups. Zk-rollups aggregate multiple transactions into a single proof, which is then submitted to the Ethereum mainnet. This approach drastically reduces the computational burden on the mainnet while still ensuring that transactions are secure and verifiable. One of the standout features of MegaEth is its ability to support parallel execution of smart contracts. This allows multiple contracts to be processed simultaneously, further boosting the network's throughput. MegaEth’s focus on zk-rollups means that it can handle a large number of transactions efficiently, making it particularly suitable for high-transaction environments like DeFi and decentralized exchanges (DEXs).

Additionally, MegaEth's architecture is designed to minimize gas fees, making it more cost-effective for users. By bundling transactions together and reducing the frequency of on-chain interactions, MegaEth lowers the overall cost of using the Ethereum network, which is a significant advantage in a network where gas fees can be prohibitive.

Risc0

Risc0 offers a unique approach to scaling Ethereum by introducing a zk-SNARK-enabled coprocessor. This system is designed to offload computational tasks from Ethereum to a specialized coprocessor that can handle parallel computations efficiently. The Risc0 coprocessor ensures that the results of these computations are verifiable on-chain, preserving the security and trustless nature of Ethereum. The key strength of Risc0 lies in its ability to handle complex computations that would be too resource-intensive for the Ethereum mainnet. By offloading these tasks to a coprocessor, Risc0 can execute them in parallel, thereby improving the overall throughput of the network. This makes Risc0 particularly valuable for applications that require heavy computational power, such as machine learning or scientific simulations, which can now be executed in a decentralized manner.

Risc0 also integrates seamlessly with existing Ethereum infrastructure, making it easier for developers to adopt without needing to overhaul their current systems. The use of zk-SNARKs ensures that the results from the coprocessor are not only accurate but also confidential, adding an extra layer of privacy to the network.

Connecting These Layer-2 to Vara, Sei, Sui, Monad, and Aptos

While I briefly touched on Lagrange, MegaEth, and Risc0, it's evident that these Layer-2 solutions address similar challenges just like Vara, Sei, Sui, Monad, and Aptos as layer-1 solutions. Lagrange’s use of zk-SNARKs for parallel computations closely parallels Vara's approach to parallel execution. Whereas Vara achieves this at the Layer-1 level through its foundational protocol (Gear Protocol), Lagrange provides advantages similar to Ethereum's as a Layer-2 solution. On the other hand, MegaEth, with its use of zk-rollups for transaction aggregation, draws a parallel to Monad’s strategy for high throughput in its Layer-1 architecture. Both solutions emphasize parallel execution of smart contracts; however, MegaEth does so as a Layer-2 on Ethereum, while Monad implements it natively within its blockchain. The focus on reducing gas fees in MegaEth also mirrors the efficiency objectives of the discussed Layer-1 networks.

Furthermore, Risc0’s zk-SNARK-enabled coprocessor approach is intriguing, and it resonates with Sei Network’s Twin-Turbo Consensus for rapid transaction finality. Though the technologies differ, both Risc0 and Sei share a focus on enhancing performance, where Risc0 offloads intensive computations to specialized components, and Sei achieves efficiency by distributing tasks across multiple parallel chains, enabling effective parallel processing. Now, in terms of security, the integration of privacy features through zk-SNARKs across these Layer-2 solutions also echoes the security focus found in networks like Aptos and Sui, which leverage the Move programming language to enhance smart contract security.

So overall, these Layer-2 and Layer-1 networks use different strategies to solve blockchain scalability and performance issues. Their innovations will shape the future of decentralized applications and blockchain technology. Lastly, talk about their feature from the table below.
