This is a governance attack. This passed on a technicality despite the fact a majority of MEPs voted against it. They intentionally put it up on the last day of parliament knowing that people would be on holiday and it would pass because not enough people turned out. They literally attacked the frailties of their own governance system. If you needed any further proof that these mass surveillance measures are undemocratic and authoritarian, this is it. They want this so much they're willing to undermine basic democratic legitimacy to get it. Deeply sinister and foolish. Whatever this parliament does from now on, is a joke. They will just vote on policies that incrementally destroy civil liberties until they pass on technicalities. The UK have just given themselves the powers to do this, so they don't even need to vote on it. Genuinely think we could be seeing the last days of democracy here.

zcashd will reach its end-of-life service halt on July 18, as scheduled, completing the Zcash ecosystem's migration to Rust-based, next-generation Zcash client software. zcashd will not support NU6.3 (Ironwood). Node operators will need to complete their transition to Zebra and the ZODL-maintained Zallet wallet prior July 18. Only Zebra nodes will be on the peer-to-peer network from that time onward. We've successfully worked with and continue to assist partners in their migrations to bring the ecosystem forward. Zcash is upgrading.

@mrjamesports hey you win a prize for being the first to notice!

@ebfull Right on theme with the Oct 28 launch 👌

Zcash's Ironwood mainnet activation height has been set and tagged! All of the major organizations are committed to activation of NU6.3 at height 3428143, which is approximately July 28th at 8AM EST.

Ironwood activation height is now in the code! New shielded pool, formally verified from day 0, coming July 28th!

We’re committed at @zodl_co. Good to go!

If you're looking for an active ecosystem building top notch privacy preserving technologies without bullshit, look at @Zcash. The energy within the ecosystem is as good as in the startups shipping products in production to their clients. I've rarely seen a coordination like this, mixed with expertise across multiple teams and skills. Zcash gave me back my motivation of being in crypto, mixed with engineering and research. I believed that I wanted to move back to maths as nothing was exciting anymore, but I was wrong. My love for engineering and code is back. I'm listening to as many as possible conversations in parallel, grabbing all the knowledge I can have, while still working. And I love it. And the people are serious about the vision. It's motivating to be around them.

Awesome news! While specification bugs are possible (and will be seen in many systems) auditing specification is considerably easier than auditing circuits. A specification is like an “intent” or definition which is much more interpretable to humans

Tachyon's Formal Verification project is on the verge of producing a mathematical proof that there are no undetectable counterfeiting bugs in the latest Zcash shielded pools.

A comparison of Bitcoin and Zcash on counterfeit detection. The greatest risk in private money is hidden inflation. Ironwood rules out specification bugs and puts Zcash essentially on par with Bitcoin in supply verifiability. A historic feat for private money.

Zcash's new formal verification efforts eliminate undetectable counterfeiting bugs from the new Ironwood pool.

Zcash's new Ironwood pool is being formally verified to rule out all undetectable counterfeiting bugs, up to the underlying cryptographic assumptions. tachyon.z.cash/blog/detecting…

Zcash testnet has upgraded for Ironwood! Use your freedom, and use shielded digital cash 🛡️🇺🇸

250 years ago, liberty was declared in ink and defended with muskets. Today, it's defended with cryptography. Happy Independence Day. 🇺🇸

Happy Birthday America, Land of the Free. Don’t give up on the First, Second, Fourth, and Ninth Amendments. They’re unique, and your freedom - and the worlds’ - depends on them.

@KeystoneWallet Shoutout to @czarcastic, man has been flashing firmware non-stop and has literally spent hours of life scanning QR codes to fix this for us all. At 100k+ QR codes scanned, easily .01% of human QR code'rs

🚨 Zebra 6.0.0-rc.0 is out! 🌱 NU6.3 "Ironwood" Testnet support (new shielded pool + v6 tx format) 🔐 Multiple security and bug fixes 📦 Reproducible Docker images and signed pre-built binaries for Linux via cargo binstall 🗄️ State DB upgraded in place - no resync needed 🦓 Zebra-mined blocks now tagged with a 🦓 in the coinbase input Testnet operators: please test ahead of 6.0.0 final 👇 zfnd.org/zebra-6-0-0-rc…

1/ Super excited to share a recent @lagrangedev research highlight: ZKPs face challenges with computations involving non-polynomial functions, e.g., sin(x), exp(x) appearing in ML and DeFi applications, for example. We introduce a framework that improves the SOTA on this front.

github.com/zcash/zcash Thank you buddy. You did great. 🥹 It's such a great thing that @ZcashFoundation built Zebra 🦓 a Rust, Memory-Safe, battle-tested, Zcash protocol fully spec compliant node. Congratulations again to the ZF engineering team. If you are running Zcashd and you don't have a Zebra running already, you should start doing so now. GO GO GO! github.com/zcashfoundatio…
