The team behind Zakura, a newer version of the Zcash software, has proposed giving each ZEC swap made through NEAR Intents its own private viewing key. The goal is to ensure that a refund address left on NEAR’s public chain cannot expose a user’s wider payment history, even to a future quantum computer that could reverse-engineer keys. This is not about fear; it is about humility — acknowledging that today’s safe solutions may become tomorrow’s vulnerabilities. The Prophet (peace be upon him) said, “Do not harm and do not reciprocate harm.” Here, the potential harm is the exposure of people’s financial lives by a technology that does not yet exist but likely will. Zakura is patching a hole before anyone provably exploits it, rather than waiting for a crisis. That contrasts with the pattern of transgression warned about in Surah Al-Fajr, where powerful peoples like ʿĀd and Thamūd spread corruption and were destroyed because they were deceived by their own strength. Quantum computing may not be commercially viable yet, but dismissing the risk would be to repeat that arrogance. This fix — per-swap viewing keys — is a small technical detail, but its principle matters for the entire crypto industry: security is not a product you buy once, but a continuous practice of foresight. It also shows that privacy-focused projects like Zcash are not only about secrecy but about protecting ordinary users from systems of surveillance that could outgrow their intended use. Whether this proposal gets adopted and how it interacts with NEAR’s design will be worth watching, but the intent itself is a rare example of proactive conscience in a space often driven by hype.
