Bitcoin Difficulty & The Rise of Avalanche + Proof of Work

How Bitcoin’s Difficulty Adjustment Works

Bitcoin was designed with a clever mechanism to keep block generation consistent: the difficulty adjustment algorithm. Every 2016 blocks (around two weeks), the network recalibrates based on block speed.

• If blocks were too fast → difficulty increases
• If blocks were too slow → difficulty decreases
• Target: 1 block every 10 minutes

The Weaknesses of Pure Proof of Work

• ⚡ High energy use
• 🏭 Centralized mining risk
• ⏳ Slow response to network changes

eCash’s Innovation: Avalanche + Proof of Work

eCash (XEC) adds the Avalanche consensus layer on top of PoW. This hybrid called APoW combines the best of both worlds:

• Near-instant finality
• Stronger pre-consensus
• More intelligent difficulty tuning
• More inclusive mining future

Conclusion

Bitcoin built the foundation. eCash upgrades it. Avalanche + Proof of Work is how we move toward a faster, fairer, and more efficient blockchain ecosystem.
