The ME Network, developed by Meta Earth’s technical team over three years, is a modular blockchain multi-chain fusion network. One of the main research solutions of the ME (Meta Earth) Network is modular technology. Meta Earth is committed to supporting high-concurrency big data processing needs in diverse scenarios, making it essential to build a high-performance and infinitely scalable underlying network.
In this article, we will take you through how the ME Network decouples its architecture into: the Execution Layer, Settlement Layer, and Data Availability Layer, and what specific roles and functions each core layer performs.
1. Execution Layer: The Key to Efficient Processing
The Execution Layer is responsible for transaction execution, handling ordinary transactions, and smart contract interactions (computations). In the ME Network, the Execution Layer can be considered the top layer of the blockchain technology stack.
In the ME Network, the most common example of an Execution Layer is Rollup, where computations are executed off-chain, and the results (i.e., state roots) are published to the Settlement Layer, while transaction data is compressed and packed into the Data Availability Layer. Since transaction computations are offloaded to off-chain, it significantly reduces the burden on the ME Network’s main chain (ME Hub) and can achieve extremely high TPS and reduced Gas Fee consumption.
Of course, ME Hub (Settlement Layer) itself is also an independent blockchain supporting smart contracts. Users, who do not consider the advantages of lower Gas Fees and execution concurrency, can also choose to execute on ME Hub, similar to deploying contracts on Ethereum. Additionally, ME Network discourages deploying and running heavy applications on the Settlement Layer to maximize space for Rollup.
2. Settlement Layer: The Core of Transaction Finality
The Settlement Layer is responsible for the final confirmation of transactions, including dispute resolution, proof verification, and bridging different Execution Layers. This layer receives the state and results of business processing from the Execution Layer, ensuring the “soft” security of the Execution Layer, preventing fraud, and batch processing, reaching a consensus on all the states and results processed by the Execution Layer.
Generally, the Settlement Layer maintains the registries of deployed Rollup-chains and their corresponding important information, such as status, staking, sequencer list, sequencer management, fraud proof adjudication, etc., so that the Settlement Layer can provide security and settlement services for the Rollup-chain.
In the ME Network, the Settlement Layer can also provide other functions for the Rollup-chain, such as a source of liquidity and a bridging center. Therefore, the Settlement Layer is also called the ME Hub. Additionally, the Settlement Layer of the ME Network has the following uses:
-Proof Verification and Dispute Resolution: The Settlement Layer provides a place for Rollups to post proofs for external verification. This is particularly useful for Optimistic Rollups, which rely on fraud proofs.
- Bridging Center: If multiple Rollups use a common Settlement Layer, they can bridge each other. This eliminates the need for separate bridges between Rollups.
- Source of Liquidity: The liquidity existing in the Settlement Layer can be used by all the Rollups on it. Besides using the token on the main chain, Rollup-chains can also construct their own tokens. Different tokens can naturally cross-chain to the ME Hub Settlement Layer through MBC, achieving free liquidity and exchange.
Clearly, in a modular cross-chain, the Settlement Layer provides underlying consensus and security mechanisms for the Execution Layer. When building their Rollup-chains, there is no need to deploy validation nodes, significantly reducing operational costs.
3. Data Availability Layer: The Key to High Scalability
Data availability is a crucial component for the ME Network to achieve high scalability. It is responsible for receiving business data from the Execution Layer and storage, acting as the storage module for Rollup data, ensuring the availability of transaction data, and ensuring that anyone can access and verify the data, thus guaranteeing the security of the Execution Layer and achieving consensus.
The Data Availability Layer itself does not execute any smart contract protocols and does not involve any computations. Its core function is to ensure the correctness and availability of transaction data, providing materials for “fraud proofs,” or helping users trace assets and reduce losses in case of network attacks. Therefore, even when nodes do not participate in consensus maintenance and do not need to store all transaction data, they can still verify transactions and prove whether a transaction is available. The Data Availability Layer is an important complement to the entire ME Network, providing double insurance for information security.
Additionally, the Data Availability Layer features unique data distribution, data propagation links, and storage space, contributing to the efficient operation of the main chain (ME Hub), thereby maximizing the performance of the ME Network.
In conclusion, through the collaborative operation of the above three core layers, the ME Network not only meets high concurrency and big data processing needs but also achieves infinitely scalable characteristics, providing a solid technical foundation for applications in diverse scenarios. In the future, the ME Network will continue to lead the technological frontier through ingenious architecture design and outstanding technological innovation, creating a broader and better digital ecosystem, bringing a more efficient, safer, and more convenient blockchain experience to every ME user.
