AnnouncementDear Meta Earth nodes and community members,
To advance the ME Network upgrade and the decentralization of ecosystem governance, the ME DAO is officially initiating a vote on the ME Network V2.0.16 upgrade proposal. This vote will be jointly decided by all validator nodes of ME Hubs (excluding the Experience Zone), and the results will be made public via the on-chain governance tool. If the proposal is approved, the ME Network will automatically execute the upgrade process upon reaching the specified block height.
I. Basic Proposal and Voting Information
• Proposal Number: Major Event Proposal On-Chain ID: 5
• Proposal Topic: ME Network Upgrade to V2.0.16
• Proposal On-chain Time: August 16, 2026, 00:00:00 (UTC+0)
• Voting Period: August 16, 2026, 00:00 -- August 17, 2026, 23:59:59 (UTC+0)
• Upgrade Schedule:
º Upgrade Block Height: 14,565,500
º Estimated Upgrade Maintenance Time: August 19, 2026, 00:00 (UTC+0) (The exact time depends on the block generation height)
º Estimated Upgrade Maintenance Duration: During the upgrade, the network will suspend services. Node restarts and service recovery are expected to take approximately 8 hours.
• Participation Eligibility: Limited to all running zone validator nodes on the ME mainnet (excluding the Experience Zone).
• Voting Results Inquiry:

II. Core Upgrade Content (V2.0.16)
The core content of this Meta Earth Network V2.0.16 upgrade is as follows:
• New Features: Added support for binding ME ID accounts and their sub-account addresses. Added pagination to the NFT query interface to improve query efficiency and user experience when handling large volumes of data;
• Bug Fixes: Fixed known issues, including issues related to the EVM module, to ensure the proper operation of EVM contract functionality;
• Security Enhancements: Strengthened parameter validation for Meta Earth public chain APIs and added scenario-specific validation rules. For example, NFT minting now validates the minting quantity to prevent it from exceeding the total issuance limit;
• Rule Adjustments: Optimized certain underlying rules of the Meta Earth public chain and completed the EVM Chain ID adjustment to improve network configuration standards and compatibility;
• Performance Optimizations: Restructured the staking reward calculation mechanism and optimized the BeginBlock block reward accounting logic to improve reward calculation accuracy and block processing efficiency.
This update also includes optimizations and fixes for other functions to enhance system stability, security, and user experience.
III. Voting Rules
• Options:
º Support (AGREE): Agree to execute the on-chain V2.0.16 upgrade.
º Oppose (REJECT): Reject this upgrade and retain the current protocol version.
• Weight Calculation: Each zone validator node of an ME Hub (excluding the Experience Zone) holds one vote.
• Passing Criteria: Affirmative votes must account for more than 50% of the total number of running nodes participating in the vote.
IV. Node Upgrade Operation Guide
• Upgrade Preparation:
º Back up node data (e.g., the ~/.mechain directory).
º Download and compile the latest code for version V2.0.16.
• Upgrade Process:
º After the network reaches the specified block height (14,565,500), the node will automatically stop and run the upgrade program.
º Restart the node using version V2.0.16.
º Check the node logs to confirm that block synchronization is proceeding normally.
Thank you for your long-term support and contribution to the Meta Earth ecosystem!
