With the rapid development of blockchain technology, various architectural designs have emerged in the market, among which modular blockchain and monolithic blockchain are the most representative. The entire industry is seeking to solve the "blockchain trilemma," which is the simultaneous realization of security, scalability, and decentralization. Therefore, understanding the core differences between these two architectural designs is crucial. This article first takes you through the advantages and disadvantages of monolithic blockchains and modular blockchains, as well as the confidence behind ME Network becoming the most widely adopted modular network.

What is a Monolithic Blockchain?

A monolithic blockchain is a blockchain network that operates on a single layer, executing all critical duties (transaction execution, data availability, and consensus) within the same architectural framework. It provides a straightforward approach for blockchain developers. Bitcoin is a typical example of a monolithic blockchain.

Advantages of Monolithic Blockchains:

• Simplicity: Monolithic blockchains can directly implement the blockchain network through single-layer design, making it easier for developers to build and maintain systems. This simplicity also makes it easier for new users to understand its technology and functionality.

• Security and Reliability: Monolithic blockchains like Bitcoin have proven their security and reliability since their inception. Their success has established a solid foundation of trust and credibility for these monolithic blockchain networks.

Disadvantages of Monolithic Blockchains:

• Limited Scalability: The single-layer design of monolithic blockchains may hinder their ability to scale effectively. As transaction volumes increase, these networks may become congested, leading to longer transaction processing times and higher fees.

• Difficult Upgrades: Due to their inflexible design, implementing changes and improvements in monolithic blockchains can be challenging. This rigidity makes it difficult for the network to adapt to emerging demands and technological advancements.

What is a Modular Blockchain?

Modular blockchains adopt a layered architectural design, separating the primary tasks executed by the blockchain network (including executing transactions, ensuring data availability, and achieving consensus on the true state of the blockchain). By distributing these functions across different layers, modular blockchains aim to address the "blockchain trilemma," which is solving the challenge of achieving security, scalability, and decentralization simultaneously.

Advantages of Modular Blockchains:

• Scalability: By separating key processes, modular blockchains can achieve higher transactions per second compared to traditional blockchains. This separation allows each layer to optimize its processes without being constrained by bottlenecks in other layers.

• Specialization: Each layer can be independently optimized to excel in its specific function, potentially leading to better overall performance and more advanced technological development.

• Flexibility: Users and developers can choose different combinations of modules based on their specific needs. For example, they can select a particular consensus mechanism that meets their security and speed requirements while choosing a different execution layer tailored for complex computations.

• Interoperability: Modular design can facilitate better interoperability between different blockchain systems. Since each layer can interact with similar layers on other networks, cross-blockchain interactions are simplified.

• Upgradability: Updating a modular blockchain can be simpler because changes can be made to one module without affecting others. This can lead to faster innovation cycles and easier maintenance.

Disadvantages of Modular Blockchains:

• Security Issues: Unlike monolithic chains, which can enforce their own security, modular chains rely on an independent security layer (handling consensus and data availability) to ensure validity. If this security layer fails, the entire modular chain is at risk of failure.

• Increased Complexity: Implementing a modular design introduces new complexities compared to monolithic chains. Mechanisms such as data availability sampling, fraud proofs, and validity proofs are needed to allow the security layer to verify off-chain computations. This added complexity increases the risk of vulnerabilities and makes development more challenging.

Our Confidence in Modularity

In the field of modular blockchains, although ME Network is not the first, we are confident that we will become the most widely adopted modular network. This confidence stems from our in-depth research into modular technology solutions over the past three years, providing a solid technical theoretical foundation to support the diverse application scenarios of Meta Earth in the future. ME Network adopts an innovative modular blockchain design, decoupling both vertically and horizontally and incorporating Rollup technology to create a layered design for public chain architecture.

Horizontal decoupling mainly divides it into three modules: the execution layer, the settlement layer (including state verification consensus), and the data availability and consensus layer (Txn consensus). The execution layer is responsible for executing transactions and deploying and interacting with application chains or smart contracts; the settlement layer is responsible for finalizing transactions, resolving disputes, and verifying evidence, while also bridging different execution layers; the data availability and consensus layer is responsible for receiving business data from the execution layer, storing it, ensuring the hard security of the execution layer, and reaching consensus. In this way, ME Network separates core consensus maintenance from transaction execution while ensuring stable data availability and efficient resource utilization, greatly enhancing the flexibility of modular architecture.

Vertical decoupling in ME Network classifies business functions within the blockchain into various functional modules, meaning that functions such as transaction broadcasting, account balances, and consensus mechanisms are handled by separate modules rather than being tightly integrated. This makes ME Network easier to maintain and allows it to flexibly respond to evolving technological and market demands. In the future, ME Network will also develop an all-in-one development component, ME SDK, simplifying the development process and providing out-of-the-box functionality, thus offering developers and users a flexible, secure, and efficient blockchain development and usage environment.

Currently, ME Network v1.0 has entered the public beta phase, and the design of the modular chain architecture is still ongoing. To accelerate community growth and lay a solid community foundation for the widespread adoption of ME Network, ME has designed a unique token economic model combining unconditional basic income for users and 100% community output. During the public beta period, generous growth incentives and airdrop activities have been launched.

Conclusion: Although monolithic blockchains are still mainstream and occupy most of the public chain market, modular blockchains, as an emerging design paradigm, undoubtedly expand the application prospects of blockchain technology by improving scalability, flexibility, composability, and maintainability. They provide powerful and flexible infrastructure for the construction of the digital economy and blockchain networks, showing great potential in a broader range of fields. Perhaps in the near future, modular blockchains will bring us even more unexpected surprises!
