Can zcash:native actually verify it's own money as privacy coin? We are so far along to the ultimate privacy protocol, but zcash gave it's decent start. But why privacy coin hunters are dumping zcash:native beyond the claude opus 4.8 critical vulnerability expose? 1. The anonymity set is small, which directly weakens the protocol People assume strong proofs equal strong privacy. They do not. Privacy is a function of the math AND the crowd size. zk-SNARKs give you perfect unlinkability inside the shielded pool, but unlinkability only means "you cannot be distinguished from the other people in the pool." If the pool is small or low-activity, the set you are hiding in is small. Concretely: roughly 30% of ZEC supply was shielded as of 2025. But supply shielded is not the relevant number. What matters for privacy is transaction activity, how many shielded-to-shielded transactions are happening in the same time window as yours. A large dormant shielded balance gives you almost no cover, because cover comes from concurrent activity, not stored value. If only a handful of shielded transactions clear in the window around yours, an analyst is correlating across a tiny set. The math says you are anonymous. The usage says you are one of five. ZEC cannot fix the anonymity set by improving the cryptography, because the cryptography is already excellent. It can only fix it by driving real shielded usage up, and it has failed to do that for nearly a decade. The potential weakness is on demand side. 2. Optional privacy poisons as the default When privacy is opt-in, using it becomes a signal. On Monero, everyone is private, so being private tells an observer nothing. On Zcash, choosing to shield marks you as someone who wanted to hide something, within a minority of users who do. The act of opting in is itself information. This produces a perverse dynamic. The more sensitive your reason for wanting privacy, the more your use of the rare feature stands out against the transparent majority. Optional privacy means the privacy-seekers self-select into a smaller, more conspicuous group. Monero's mandatory model dissolves that signal entirely. Zcash's optional model concentrates it. The feature that is supposed to protect you also flags you, because most people around you are not using it. 3. The shielded boundary leaks by design Most ZEC value needs to touch the transparent world. Exchanges deposit and withdraw transparent. Most wallets, most liquidity, most on-ramps are transparent. So value flows in a pattern: transparent, shield, do something private, unshield, transparent again. Every shield and unshield event is visible on-chain with an amount and a timestamp. The shielded middle is private. The two ends are not. This creates correlation attacks. Shield 12.7 ZEC at 14:02, and an unshield of 12.7 ZEC appears at 14:40, a chain analyst has a linkage hypothesis. With low pool activity (see point 1) these hypotheses get strong fast, because there are few other transactions to create ambiguity. This is structural because the protocol cannot close it without forcing all activity shielded, and it deliberately refuses to do that, because mandatory privacy is exactly what triggers delistings. So ZEC keeps the leaky boundary on purpose. The leak is the price of regulatory survival. It is not a bug they will patch. It is a design they chose. 4. The shielded pool sacrifices supply verifiability This is the deepest one and the one this week made it concrete. A transparent chain lets anyone verify total supply matches protocol rules. A shielded pool gives that up. You cannot see the amounts, so you cannot confirm the amounts sum correctly. For years this was a theoretical tradeoff. The Orchard bug converted it into a live liability. A soundness flaw let counterfeit ZEC be minted inside the pool with no on-chain trace, and because the pool hides amounts, there is no cryptographic way to prove after the patch whether it happened. The privacy did not just fail to help here. It is the specific reason the question is unanswerable. On Bitcoin, a counterfeit bug would leave a supply discrepancy anyone could check. On ZEC, the privacy guarantee erases exactly the evidence you would need. So the structural compromise is this: privacy and provable integrity are the same axis pointing opposite directions. You cannot maximize both. Every unit of privacy ZEC provides is a unit of supply-verifiability it gives up. Most of the time nobody notices. When a soundness bug appears, that abandoned verifiability is precisely what you cannot get back. If the team executes on the NU7 roadmap, faster blocks (75 seconds down to 25), and the Zashi and NEAR Intents UX improvements that are already moving real cross-chain volume into shielded ZEC, the set can grow. At this moment, adoption is the only variable that matters, and it is the one thing within their control. They have not cleared it yet, but it is clearable, and unlike the regulatory and verifiability tensions, it does not require them to abandon what makes ZEC, ZEC.

After seeing the news on the overall tech sell-off and @binance’s largest hack, I concluded that X is still a much better place to curate your source. There are a lot of misleading takeaways and hyperbolic perceptions regarding the $BTC pullback, which is likely also factored by broader risk appetite not the hack itself, especially from the developing story by @CNN's tech reporter. $BTC being down only 4% post $6B hack proves it's resistance and being battle tested against scenarios. Still not bearish x

Was advising this early stage security project building signing layer for crypto. It would’ve prevented Binance hack even if device is stolen and compromised. Solid team, one of the co-founders was involved in very high level opsec government project in a country in EU. Managed to launch retail, institutions and even prototype on agent stack and pilot onboarding with on chain protocol with $400M TVL but things have been very slow and they haven’t been able to close their round. It’s crazy how security projects in the space is so underfunded. Seriously what are we doing as an industry in collective? Why we keep funding useless protocols? @_SEAL_Org @zachxbt @binance

This year, I have been thinking and allowing myself to feel a mix of excitement and hope, but at the same time, fear and dread. As someone who's been told as highly perceptive, it's been quite heavy to carry. If you are between the ages of 20 and 28, we are constantly faced with an abundance of intelligence and a world that seems to be rapidly drifting away from the 'old ways.' and I'm certain it hasn't always been easy to navigate. We were taught that mastering predictable, orderly disciplines was the way to go, until recent breakthroughs proved otherwise. I can't even explain how many people don't seem to be aware of this shift, thinking that in the end, economic implications are what matter most. Most importantly, don't lose yourself and hope on what kind of life you wanted to live trying to make sense of everything <3

No amount of fancy dinners or exclusive events can fix this. If you’re expecting allocators, fix this for God’s sake. Why we never learn from the past?

What I like about Kanye concert in Jakarta is how unbelievable the overall experience is. It’s a melting pot of fit and hot people, behaving (no alcohol policy), good crowd control and insanely friendly staffs and cops (Indonesians for you), clean venues, and overall feeling super safe going as girls. We even went home at 5 AM and still felt safe. I couldn’t imagine going to European/ US concert. I feel more safe and respected during concert in so called third world country.
