Bitcoin's conception was immaculate and new blockchain projects can't hope to match that, yet alone beat it. But Bitcoin can be challenged on technical aspect. We identify four properties that Bitcoin is lacking:
- throughput scalability (is being fixed)
- programmability (could be fixed)
- privacy (could be fixed)
- post-quantum security (can't be fixed)
