One thing this incident reminds us is that protocol upgrades aren't just about adding features—they're about solving real-world problems. For years, many argued Bitcoin should never evolve. Now we're seeing more people discuss vaults, covenants, and safer custody models after experiencing the limitations firsthand. Bitcoin Cash chose a different path: keep the base layer efficient while carefully expanding its capabilities. CashTokens, native covenants, richer scripting, and now even on-chain zk-proof verification all came from that philosophy. Good upgrades aren't about change for the sake of change. They're about giving the protocol the tools it needs to solve tomorrow's problems.
