Mining Token Contract (MNT)

A sophisticated ERC20 token implementation with mining rewards functionality built on the Ethereum blockchain.

Features

• Capped Supply: Token has a maximum supply limit defined at deployment
• Mining Rewards: Miners receive automatic token rewards for block validation
• Ownership Control: Contract includes owner-specific functions for parameter management
• Decimal Support: Full decimal support (18 decimals) for token operations
• Initial Supply: 50,000,000 tokens minted to deployer at contract creation
• Adjustable Block Rewards: Owner can modify mining reward amounts

Technical Details

Token Specifications

• Name: MiningToken
• Symbol: MNT
• Decimals: 18
• Initial Supply: 50,000,000 MNT
• Supply Cap: Defined at deployment

Smart Contract Architecture

The contract inherits from:

• ERC20Capped: Implements maximum supply cap functionality
• Ownable: Provides ownership control mechanisms
• ERC20: Base token implementation

Key Functions

1. Constructor

   • Sets token cap and initial mining reward
   • Mints initial supply to contract deployer

2. Mining Reward System

   • Automatic reward distribution to miners
   • Anti-manipulation checks for miner rewards
   • Configurable reward amounts

3. Administrative Functions

   • setBlockReward: Allows owner to adjust mining rewards
   • Protected minting with cap validation

Usage

1. Deploy the contract with parameters:

   • cap_: Maximum token supply
   • reward_: Initial block mining reward

2. Miners automatically receive rewards when processing transactions

3. Contract owner can adjust mining rewards using setBlockReward

Security Features

• Supply cap enforcement
• Protected minting mechanism
• Miner reward validation
• Owner-only administrative functions

Dependencies

• OpenZeppelin Contracts v4.x
  • ERC20
  • ERC20Capped
  • Ownable
