Detailed Upgrade Details

Below are the specific upgrade details for ME Network 2.0, ME Pass 3.0, ME Pass Lite, Plugin Wallet, and Meta Earth Blockchain Explorer.

1. ME Network 2.0 Upgrade Details

According to the major on-chain governance proposal (Proposal No. [1]), ME Network has successfully completed its 2.0 upgrade at block height 6,624,500, marking its official entry into a new phase centered on modular architecture. This upgrade further decouples the execution, consensus, and data availability layers, laying a solid technical foundation for Rollup deployments, multi-chain interoperability, and global node expansion. The new architecture enhances ME Network’s scalability, security, and ecosystem compatibility, providing critical support for the long-term growth of the modular blockchain ecosystem.

1.1 Architecture Upgrade: Modular Layering  

   ￮ Three-Layer Decoupled Architecture:  

         ▪ Execution Layer (RollApp): Sovereign Rollup chains support parallel processing and customizable VMs (EVM/WASM), enabling flexible business expansion.  

         ▪ Settlement Layer (ME-Hub): Built on Tendermint BFT consensus, providing global state finality and cross-chain interoperability.  

         ▪ Data Availability Layer (ME-DA): Integrates an improved Celestia scheme (DAS + Erasure Coding), reducing storage costs by over 98%.

   ￮ Core Advantages After the Upgrade:  

         ▪ Increased throughput.  

         ▪ Optimized storage costs.  

         ▪ Enables rapid business iteration.

1.2 Economic Model Reform  

   ￮ Unified Token System:  

       ▪ MEC serves as the base token across all three layers:  

       ▪ RollApp utilizes cross-chain mapped MEC-CI for gas fees and governance.  

       ▪ The data availability layer uses cross-chain mapped MEC-DA.  

       ▪ Native tokens of RollApps and the data availability layer are deprecated; initial temporary tokens are automatically burned.

   ￮ Fee Circulation Mechanism:  

         ▪ Users only pay local gas fees on RollApps, while Sequencers cover cross-layer fees (data availability layer and MEC).  

         ▪ Cross-chain transaction fees are automatically converted to MEC, creating a closed value loop.

1.3 Key Technical Upgrades  

   ￮ Decentralized Sequencer Network (v2.1):  

       ▪ Consensus Mechanism: Integrated with CometBFT (formerly Tendermint), supporting multi-node round-robin block production and dynamic election.  

       ▪ Security Enhancements:  

             • Slashing Mechanism: Malicious nodes forfeit staked MEC.  

             • Fraud Proofs + ZKP Compression: The Groth16 algorithm reduces gas costs by 90%.  

             • Watch Relayer: Monitors anomalies and triggers challenges in real time.

   ￮ Data Availability Layer (ME-DA):  

       ▪ Core Technologies:  

             • Data Availability Sampling (DAS): Light nodes only verify 1–2% of data shards.  

             • 2D Erasure Coding: Enables recovery from up to 50% data loss.

             • Storage Cost: Full node storage requirements reduced by 98%, with near-zero costs for light nodes.

   ￮ Cross-Chain Communication – MBC(eIBC):  

       ▪ Addressing Optimistic Rollup Pain Points:  

          • Instant Withdrawals: Market makers prepay users to bypass dispute periods.  

          • Verification Incentives: Market makers earn fees while assuming fraud detection responsibilities.

   ￮ EVM Compatibility:  

       ▪ Ethermint Integration: Supports Solidity 0.6.0–0.8.17, compatible with Ethereum tools like MetaMask.  

       ▪ Dual VM Coexistence: EVM and WASM contracts can interact across chains, covering both Ethereum and Cosmos ecosystems.

   ￮ DID-Based Unique Identity Authentication System:  

       ▪ On-Chain Lightweight Storage: Only the hashes and URLs of VC certificates are stored on-chain, with encrypted private data stored off-chain.  

       ▪ Cross-Chain Verification: Shared state via the Hub enables issuers to proactively update credentials (e.g., credit scores).

   ￮ 1.4 Other Critical Improvements:  

       ▪ Osmosis Module Adjustments:  

             • Dynamic gas pricing (based on transaction type and network congestion).  

             • Anti-Sybil Measures (exponential gas growth for high-frequency transactions).

   ￮ Relayer Optimization:  

         ▪ Compatible with NMT proofs and Cosmos SDK’s Merkle proof conversion.  

         ▪ Trustless design ensures secure cross-layer communication.

   ￮ Comprehensive Security Enhancements:  

         ▪ Decentralized Sequencer (requires 2/3 honest nodes).  

         ▪ Real-time Hub validation of DA commitments, with shorter fraud challenge response time.

           • 1.5 MEC Staking for First Batch of ME-DA Layer Validators  

   ￮ Initial Allocation for 4 Validator Nodes:  

         ▪ Source of Allocation: The required MEC for the first 4 validator nodes is provided by the top 4 regional treasuries of ME Hub based on staking amounts (IND, CHN, ME_EARTH, USA).  

         ▪ Allocation Ratio: Calculated as 0.01% of the respective regional treasury’s staked amount, cross-chain transferred to the ME-DA Network.  

       ▪ Total Allocation: 552,900 MEC. The specific MEC amount allocated by each region is as follows:  

         • IND: 177,600 MEC  

         • CHN: 177,200 MEC  

         • ME_EARTH: 155,800 MEC  

         • USA: 42,300 MEC

   ￮ Future Principles for DA Layer Deployment and MEC Allocation:  

     ▪ Based on the national/regional treasuries of ME Hub, provide long-term economic support for the ME-DA layer.  

     ▪ In accordance with DAO governance processes, apply for cross-chain allocation of treasury MEC to the ME-DA layer through proposal voting, ensuring transparency of MEC usage and traceable processes.  

     ▪ All allocated MEC is strictly limited to staking for validator nodes of the same name in the ME-DA layer. The tokens cannot be withdrawn, transferred, or redistributed, and are only permitted for block production and data availability services within the DA layer network.  

     ▪ Validator node names in the ME-DA layer remain consistent with the country/region names in ME Hub (e.g., CHN in ME Hub corresponds to CHN in the ME-DA layer).  

     ▪ MEC allocation mechanisms will be dynamically adjusted based on the ME Network’s adoption scale and the actual validation needs of the DA layer, with all adjustments decided through proposals voted on by node communities.
