Notice(MemeCore Initial Release)

v1.14.0 is the first official release of Go MemeCore implementation for the already launched MemeCore Mainnet, based on Geth v1.13.15. All MemeCore network participants should install v1.14.0 to ensure compatibility with the network. Binary installation is required.

This initial release includes core functionality and essential features:

1. Full implementation of the MemeCore protocol (Ethereum-compatible) based on Geth v1.13.15
2. Implementation of PoSA (Proof of Staked Authority) consensus mechanism with validator and reward contract integration
3. Support for MemeCore Formicarium Testnet with optimized network parameters
4. Health check functionality using HTTP status codes integration with syncing status indicators

ChangeLog

v1.14.0 is the initial release of the MemeCore protocol based on Geth v1.13.15 codebase. The following key changes were made to create the Go MemeCore implementation:

• Refactored codebase for MemeCore, renaming from go-ethereum to go-memecore
• Renamed client from 'geth' to 'gmeme' throughout the codebase
• Added Formicarium network support for testing

Besides code adaptation, there are several important features/improvements in this first MemeCore release:

CONSENSUS

• Implemented PoSA (Proof of Staked Authority) consensus mechanism
• Integrated validator contract for PoSA with dynamic validator set management
• Added configurable event logging for PoSA consensus engine with --posa.enable-event-logging flag
• Added minimum value to delay for signer which is not in turn for improved fairness
• Fixed validator set verification in PoSA for increased security
• Improved snapshot management about recents for better validator rotation
• Enabled Shanghai EVM features with PoSA integration
• Enforced coinbase address to reward contract for proper reward distribution
• Moved validator list check to Finalize() for better protocol compliance

NETWORK

• Added MemeCore Formicarium Testnet support for testing environment
• Updated MemeCore Formicarium testnet and MemeCore mainnet genesis configuration
• Updated MemeCore's bootnodes configuration for stable network connection
• Updated system contract positions and configurations for validator and reward contracts
• Updated genesis setting with appropriate parameters

RPC & FEES

• Added health check (is synced) capability for AWS Load Balancer integration (returns 200 if synced, 503 if not)
• Refactored and enabled debug API with selective method filtering (--http.api.debug)
• Added commenting and improved API method filtering for better security
• Increased default RPCTxFeeCap to 1500 for better transaction handling
• Added specific health check option flag (--health)

PERFORMANCE & FEES

• Fixed block reward settlement and improved validator contract
• Added phase1 static block reward (Phase1BlockReward = 1125 * 10^17 wei)
• Optimized gas estimation for MemeCore transactions
• Increased minimum base fee from 1 Gwei to 1500 Gwei for improved network economics
• Decreased BlobTxMinBlobGasprice from 1500000000000 to 1500 for optimized blob transaction handling
• Changed the amount of block reward for better validator incentives
• Increased default RPCTxFeeCap to 1500
• Increased efficient GasLimit by reducing the gas reserved for systemTx

CORE & VM

• Moved PoSA configuration to ethconfig for better separation of concerns
• Fixed opRandom in core/vm to handle null Context.Random scenarios
• Added support for empty withdrawals in block fetcher
• Updated backend instance usage when importing chain for improved stability
• Avoided panic if validator reward settlement failed
• Added balance overflow check before contract settlement
• Fixed prepare error handling in PoSA consensus
• Moved error check just behind ecrecover for better error handling
• Allows running with possible system contract errors for improved resilience
