This document outlines the security requirements and guidelines for DataHive's Core Protocol smart contract interactions and token handling mechanisms.

Security is fundamental to the DataHive protocol infrastructure. These guidelines ensure the safety and integrity of protocol operations, smart contract interactions, and token handling across the entire ecosystem.

// Protocol-Level Security Requirements
stake():
  - Input validation
  - Balance verification
  - Reentrancy guard implementation
  - Event emission verification
  - Gas limit enforcement: <= 120,000 gas

unstake():
  - Lockup period validation
  - Balance verification
  - Reentrancy protection
  - Event emission checks
  - Gas limit enforcement: <= 100,000 gas

claimRewards():
  - Reward calculation verification
  - Double-claim prevention
  - State update validation
  - Event emission checks
  - Gas limit enforcement: <= 150,000 gas
