Since the launch of the mainnet public testing in April 2024, ME Network has operated with year-long stability. As one of the few public blockchains to pioneer modular chain architecture deployment on mainnet, ME Network has steadily transformed the concept of modular blockchains into reality—validated through real-world testing, ecosystem integration, and continuous architectural refinement.

Today marks a significant milestone: the official release of ME Network 2.0.

This upgrade is not merely about performance—it's a fundamental redefinition of architecture. By fully decoupling the execution, settlement, and data availability layers, the new version delivers a more stable, efficient, and customizable modular foundation. Meanwhile, major components such as the token system, cross-chain communication, identity infrastructure, and security mechanisms have also evolved comprehensively, signaling ME Network's entry into a more mature, autonomous, and open phase.

In the sections that follow, we will outline the core technical highlights and architectural advancements of ME Network 2.0, revealing the design logic behind them—and the critical role they play in enabling the real-world adoption and scalable deployment of modular blockchain networks.

Upgraded Core Architecture: Unlocking a New Paradigm of Three-Layer Decoupled Modularity

ME Network 2.0 has achieved full decoupling across its three foundational layers—Execution (RollApp), Settlement (ME-Hub), and Data Availability (ME-DA):

• Execution Layer – RollApp: Enables parallel execution of sovereign rollups, supporting both EVM and WASM virtual machines to accommodate diverse application needs and enhance the network’s scalability and flexibility.

• Settlement Layer – ME-Hub: Built on Tendermint BFT consensus, it ensures global state finality and robust cross-chain interoperability.

• Data Availability Layer – ME-DA: Integrates Data Availability Sampling (DAS) and 2D erasure coding technology, reducing full-node storage costs by 98% and making light nodes bear almost no burden.

With this layered architectural design, ME Network significantly improves throughput and storage efficiency while providing elastic capacity for rapid business iteration. Each layer focuses on its specialized function, and through standardized protocols, they can be flexibly composed—laying the foundation for a scalable, customizable RollApp application ecosystem.

Optimized Token Model: Unified Value Anchor and Streamlined User Experience

In ME Network 2.0, the token system has undergone a structural overhaul—from fragmented to unified. MEC is now established as the sole native token across all three architectural layers—Execution, Settlement, and Data Availability—serving as the foundation for value transfer, resource metering, and governance:

• RollApp Layer: Utilizes cross-chain mapped MEC-CI for gas payments and governance participation.

• ME-DA Layer: Leverages MEC-DA for validator staking and data availability verification.

• Token Simplification: All legacy test tokens are permanently burned. Native tokens on the RollApp and Meta Earth-DA layers are deprecated, bringing greater clarity and coherence to the token model.

The user interaction experience has been significantly simplified: users only pay local RollApp gas fees, while cross-layer fees are automatically handled by the Sequencer and ultimately settled in MEC—creating a seamless closed-loop token economy.

This unified model enhances overall economic efficiency and significantly lowers the barrier to understanding and using the network—for both developers and users—laying a strong foundation for ecosystem scalability and token interoperability.

Upgraded Core Systems: Comprehensive Enhancements in Performance, Security, and Compatibility

ME Network 2.0 reinforces its technical foundation through full-spectrum upgrades across key system modules, focusing on execution performance, data availability, security architecture, and VM compatibility:

• Sequencer v2.1 Network: Integrates CometBFT consensus with rotating block production and dynamic validator selection. Security is further enhanced with slashing penalties, Groth16-based zk-fraud proof compression, and a Watch Relayer system for anomaly detection and challenge triggering—boosting system robustness and defense capabilities.

• Data Availability Optimization: Combines Data Availability Sampling (DAS) with 2D erasure coding, allowing light clients to validate only 1–2% of data while maintaining integrity. Even with 50% data loss, high recoverability is achievable—significantly reducing node operation requirements.

• Cross-Chain Communication Protocol (MBC/eIBC): Introduces market maker-based instant withdrawal and validator incentive mechanisms to mitigate withdrawal latency and fraud-proof inefficiencies common in optimistic rollups.

• Enhanced VM Compatibility: Built on Ethermint, the execution environment supports Solidity versions 0.6 to 0.8.17, MetaMask integration, and natively adapts to both WASM contracts and Cosmos SDK applications—enabling high composability across virtual machine architectures.

• ME ID Upgrade: The on-chain identity system now supports verifiable credentials (VCs), adopts lightweight on-chain storage with off-chain encrypted privacy, and enables cross-chain state sync and issuer-driven updates—forming a universal base layer for multi-chain identity management.

This technical stack is not just theoretical—it has been continuously iterated in real mainnet operations and real-world applications. It is highly practical, extensible, and forms a critical pillar supporting ME Network’s future-ready modular ecosystem.

System-Level Optimization: Enhanced Network Stability and Attack Resilience

ME Network 2.0 strengthens foundational system stability and security through multidimensional enhancements focused on resource management, defense mechanisms, and inter-module communication protocols:

• Osmosis Module Enhancements:Introduces a dynamic gas fee mechanism that adjusts in real-time based on transaction types and on-chain congestion, improving overall resource utilization efficiency.Strengthens Sybil attack resistance by implementing an exponential gas cost model for high-frequency transactions, effectively curbing system abuse.

• Relayer Optimization:Adds bi-directional compatibility with both NMT (Namespace Merkle Tree) and Cosmos SDK’s Merkle structure, improving cross-module proof verification and interoperability.Adopts a trustless design to ensure data integrity and state consistency during inter-module communication.

• Overall Security Enhancements:Implements a decentralized Sequencer mechanism, requiring at least two-thirds of nodes to operate honestly to maintain consensus stability and censorship resistance.Enables real-time validation by ME-Hub of data availability commitments submitted by the DA layer. Fraud challenges are resolved with significantly reduced latency, boosting verifiability and anti-fraud capabilities across the system.

Initial DA Node Deployment: DAO Governance in Action

With the launch of ME Network 2.0, the first batch of validator nodes for the ME DA layer has been successfully deployed and staked. A total of 552,900 MEC has been allocated for this purpose, sourced from the national/regional treasuries of the top four staking zones within ME Hub—IND, CHN, ME_EARTH, and USA. The allocation was executed based on a 0.01% proportional transfer mechanism.

The Allocation Was Carried Out Strictly in Accordance with DAO Governance Procedures and Adheres to the Following Rules:

• MEC is strictly limited to staking for the corresponding validator node—withdrawals, circulation, or transfers are prohibited.

• Node names are aligned with the original treasury regions.

• Future allocations will be adjusted dynamically based on network demand and subject to community governance decisions.

This mechanism marks a milestone in ME Network’s infrastructure layer, where fund allocation, node deployment, and governance execution are fully integrated on-chain. It not only enhances the economic sustainability of the DA layer but also validates the feasibility and practicality of DAO governance under a modular blockchain architecture.

Conclusion：

For us, ME Network 2.0 is more than just a technical upgrade—it represents a realization of our core values. Modular blockchain should not remain a theoretical concept; it must evolve into infrastructure that is truly usable and scalable.

With ME Network 2.0 now officially live, we will continue collaborating with developers and communities around the world to bring meaningful applications on-chain. We extend our sincere gratitude to the over 1,000,000 ME ID users who have supported us throughout this journey.
