1// Testnet4 support
2//
3// Testnet4 is the next generation Bitcoin testnet that will replace Testnet3.
4// This module provides configuration and utilities for Testnet4 when it becomes available.
5//
6// Key improvements over Testnet3:
7// - More stable difficulty adjustment
8// - Better protection against mining monopolization
9// - Improved reset mechanisms
