The "Governance Proposal Voting for ME Network Major Upgrade" concluded on May 16, 2025, at 11:59:59 (UTC+0). According to the final tally, the proposal has been officially approved. On-chain Voting Summary: • Voting Disclosure: ME Network Blockchain Explorer www.explorer.mec.me• Voting Period: May 14, 2025, 12:00:00 – May 16, 2025, 11:59:59 (UTC+0)• Core Proposal Content: Upgrade ME Network to version 2.0 and reallocate MEC from ME Hub to ME DA layer for validator staking.• Voting Result: All 40 validator nodes across different countries (excluding testing nodes) participated and unanimously voted in favor. The proposal has been passed with full support. Next Steps Following approval, Meta Earth Network will automatically implement the 2.0 upgrade as outlined in the proposal.

Upgrade Execution Details Upgrade TimeME Network will automatically execute the upgrade at the specified block height:• Block Height: 6624500• Estimated Time: May 19, 2025, 00:00:00 – May 19, 2025, 23:59:59 (UTC+0)Upgrade Points1.1 Architectural Upgrade: Modular Layering1.1.1 Three-layer Decoupled Architecture:• Execution Layer (RollApp): Sovereign Rollup chains supporting parallel processing and customizable virtual machines (EVM/WASM) for flexible business expansion.• Settlement Layer (ME-Hub): Built on Tendermint BFT consensus, ensuring global state finality and cross-chain interoperability.• Data Availability Layer (ME-DA): Utilizing an enhanced Celestia scheme (Data Availability Sampling + erasure coding), reducing storage costs by over 98%.1.1.2 Core Advantages After Upgrade: &nbsp; &nbsp;a. Increased throughput &nbsp; &nbsp;b. Optimized storage costs &nbsp; &nbsp;c. Support for rapid business iteration1.2 Tokenomic Innovation1.2.1 Token IntegrationMEC serves as the base token across all three layers: &nbsp; &nbsp; a.RollApp uses cross-chain mapped MEC-CI for Gas fees and governance. &nbsp; &nbsp; b.ME DA Layer uses cross-chain mapped MEC-DA. &nbsp; &nbsp; c.Native tokens for RollApp and ME DA Layer are eliminated; initial temporary tokens will be automatically burned.1.2.2 GasFee Flow Mechanism &nbsp; &nbsp; a. Users pay only local Gas fees on RollApp; Sequencers cover cross-layer fees (ME DA and MEC). &nbsp; &nbsp; b. Cross-chain transaction fees are automatically converted to MEC, creating a closed-loop value system.1.3 Key Technical Upgrades1.3.1 Decentralized Sequencer Network (v2.1)• Consensus Mechanism: Integrated CometBFT (formerly Tendermint), enabling multi-node rotation and dynamic election.• Enhanced Security: &nbsp; &nbsp; ￮Staking Slashing mechanism (malicious nodes forfeit staked MEC). &nbsp; &nbsp; ￮Fraud proofs + Zero-Knowledge Proof (ZKP) compression (Groth16 algorithm reduces Gas costs by 90%). &nbsp; &nbsp; ￮Watch Relayer for real-time anomaly monitoring and challenge triggering.1.3.2 Data Availability Layer (Meta Earth-DA)• Core Technologies: &nbsp; &nbsp; ￮ Data Availability Sampling (DAS): Light nodes validate only 1–2% data shards. &nbsp; &nbsp; ￮ 2D Erasure Coding: Light nodes verify only 1-2% of data shards.• Storage Cost: Full node storage reduced by 98%, with near-zero costs for light nodes.1.3.3 Cross-Chain Communication MBC (eIBC)•Solutions for Optimistic Rollup Challenges: &nbsp; &nbsp; ￮Instant Withdrawals: Market makers pre-pay user funds, bypassing the dispute period. &nbsp; &nbsp; ￮Validation Incentives: Market makers earn fees while handling fraud detection.1.3.4 EVM Compatibility•Integrated Ethermint: Supports Solidity versions 0.6.0–0.8.17, compatible with Ethereum tools like MetaMask.•Dual VM Coexistence: EVM and WASM contracts can interact cross-chain, bridging Ethereum and Cosmos ecosystems.1.3.5 DID-Based Unique Identity System &nbsp; &nbsp; •On-Chain Lightweight Storage: Stores only VC certificate hashes and URLs, with privacy data encrypted off-chain. &nbsp; &nbsp; •Cross-Chain Validation: Shared state via ME Hub, enabling proactive updates by Issuers (e.g., credit scores).1.4 Additional Key Improvements1.4.1 Osmosis Module Optimization &nbsp; &nbsp; a. Dynamic Gas Pricing (based on transaction type and network congestion). &nbsp; &nbsp; b. Anti-Sybil Attack Measures (exponential Gas growth for high-frequency trading).1.4.2 Relayer Optimization &nbsp; &nbsp; a. Compatible with NMT proofs and Cosmos SDK’s Merkle proof conversion. &nbsp; &nbsp; b. Trustless design ensuring secure cross-layer communication.1.4.3 Comprehensive Security Enhancements &nbsp; &nbsp; a. Decentralized Sequencer (requiring 2/3 honest nodes). &nbsp; &nbsp; b. ME Hub real-time validation of DA commitments, reducing fraud challenge response time. 2. Details of allocating MEC from ME Hub to ME DA layer for verification node staking <img src="https://public.mehp.world/2025/05/17/69795c6d0bbec6a151392b39c5529687.png" alt="" data-href="" width="" height="" style=""> 2.1 MEC Distribution Plan for First 4 ME DA Validators• Transfer Source: The required MEC for staking the initial 4 validators will be reallocated from the top 4 ME Hub treasuries by stake volume: IND, CHN, ME_EARTH, USA• Transfer Ratio: 0.01% of each treasury’s current stake will be transferred cross-chain to the ME DA Network• The Transfer Amount: 552,900 MEC, with specific allocations as follows:2.2 Future Guidelines for ME DA Layer Setup and MEC TransferTo bolster the security, participation, and decentralized governance of the ME DA Layer validation network, long-term economic support will adhere to the following principles: &nbsp; &nbsp; a.Leverage ME Hub’s zone treasuries across national regions to provide sustained economic support for the ME DA Layer. &nbsp; &nbsp; b.Through DAO governance, proposals will be voted on to request cross-chain MEC transfers from zone treasuries to the ME DA Layer, ensuring transparency and traceability. &nbsp; &nbsp; c.All transferred MEC will be directly moved from ME Hub to the ME DA Layer network. &nbsp; &nbsp; d.MEC usage is strictly limited to staking for identically named ME DA Layer validation nodes, non-withdrawable, non-transferable, non-reallocable, and dedicated solely to block production and data availability services. &nbsp; &nbsp; e.Validation node names on the ME DA Layer will align with ME Hub’s national/regional names (e.g., ME Hub’s “CHN” corresponds to ME DA Layer’s “CHN”). &nbsp; &nbsp; f.Future adjustments to the MEC transfer mechanism will depend on the adoption scale of the ME Network and the actual validation demands of the DA Layer, with all changes to be determined through proposal voting by the node community. This proposal focuses on propelling the ME Network mainnet into its 2.0 phase, with core content covering modular architecture optimization, enhancements to the data availability verification mechanism, and the on-chain allocation and deployment of MEC. During the voting process, node communities responded actively, fully demonstrating the high level of coordination and foundational consensus within ME DAO on major governance decisions. The Meta Earth Association will work closely with all node communities to ensure a smooth upgrade and the effective implementation of the approved proposals. We would like to express our sincere gratitude to all node communities who participated in this vote. Thank you for your continued support and commitment to decentralized governance. It is your active participation that is driving Meta Earth toward a future that is more inclusive, more resilient, and truly community-driven.
