Kohaku represents an important step forward for @ethereum privacy infrastructure. The combination of stealth addresses with ZK proofs addresses real adoption barriers. What's particularly interesting is the explicit focus on compliance-compatible privacy. This acknowledges what

The narrative around blockchain privacy has evolved. First: privacy coins as digital cash alternatives. Then: privacy as a fringe concern for specific use cases. Now: privacy as essential infrastructure for institutional adoption. This shift is fundamental. Because you

$ZEC has maintained its commitment to privacy for years while the broader market chased other narratives. That consistency matters. What's shifted: institutional recognition that privacy is infrastructure, not ideology. The challenge remains: privacy coins served a specific use

The fungibility debate matters more than people realise. Bitcoin's transparency creates tainted coins. Exchanges blacklist addresses. Governments track flows. Your Bitcoin's history can devalue it. Gold works as money because every piece is indistinguishable. Digital assets need
bitcoin is almost digital gold but has one flaw unlike gold, it is not fungible you can not melt one bitcoin for another, its history can be used to nullify its value to make it fungible like gold, you need to add privacy, this is the last missing piece zcash

Privacy that takes 22 hours to compute isn't privacy. It's a research project. Privacy that works in real-time, on any device, with institutional-grade compliance? That's infrastructure. That's what Garbled Circuits enable at @COTInetwork. The future of Web3 isn't about

a hidden snag often goes unnoticed: while ZK conceals information from the verifier, network metadata leaks can still unmask patterns. it's crucial to ensure end to end privacy, not just zero knowledge. End-to-end privacy requires more than cryptographic proofs. It requires

The Ethereum ecosystem recognising that sovereignty requires confidentiality is validation for the entire privacy space. @COTInetwork has been building toward this moment. Our gcEVM is EVM-compatible by design. Developers shouldn't have to relearn their stack to build private

This is the conversation the industry needs. Privacy as an opt-in has failed us. It creates a false sense of security whilst leaving most users exposed. The shift to privacy-by-default isn't just philosophical. It's practical infrastructure. That's what we built @COTInetwork for.

Eli captures the core tension: decentralization requires data sharing, but privacy requires selective disclosure. ZK-STARKs solve verification without revelation. That's powerful for certain use cases. But execution privacy requires different cryptography. Garbled Circuits enable
Privacy -- there's a real challenge to provide it on decentralized blockchains. Why? We all use our smartphones and online apps for our most confidential stuff. We use it daily for payments, managing personal information and files, writing emails about folks we love or hate. We
