    Back in ~2012, I sold $30,000 worth of BTC to an anon I met on freenode. I sent him half (!) and he flew out to where I lived with a duffel bag of cash for the other half. I was a teenager, and I felt like a gangster. But it was the dumbest financial mistake I ever made.

    Imagine Bitcoin but 1) it's encrypted, using the most advanced privacy tech in the world built by expert cryptographers, 2) it makes major, continual progress week after week, actually improving and changing. That's Zcash. It's like a wet dream from the old bitcointalk days.

    Building Momentum. Zcash Update.
    Zcash is accelerating. Some are in shock. But not all of us. Many have been preparing. Many have been diligently working on the flywheel of financial freedom for some time. (1, 2, 3) We are far from...

    I've been waiting years for this moment. Zcash has flipped SHIBA INU. But there's much more work to be done. Let's get back to building.

    Zcash already had world-renowned cryptographic expertise (go ask your quant!) but now all our orgs have the resources to hire top notch talent from across the industry. Just a few days ago I hired two more incredible cryptographic engineers for Tachyon. More to come. zillions

    Really excited to have @alex_xiong_ and @colludingnode joining Tachyon full time this week! Our goal is to ship planetary scale to Zcash's encrypted money, starting with the most advanced cryptographic upgrade in Zcash's history next year.

    Zcash has a $1.3 billion dollar anonymity set, built on the best privacy guarantees deployed with existing cryptography. No trusted setup, no obfuscation, and no slowing down. Encrypt your wealth.

    I'm excited to announce that I'm hiring a team focused on shipping Tachyon in Zcash! If you're a Rust engineer who is passionate about privacy, crypto, and high assurance software -- and if you're interested in working on something meaningful -- please get in touch with me.

    I was there for the early bitcoin days and this is just like it. Every time it crashed the IQ distribution of holders shifted rightward immediately. Now we have perps accelerating the process so people like that Wei Zhao guy get liquidated for betting against freedom. Nice.

    Zcash is humanity's first mathematically fungible asset. Much like when time and space switch places in a black hole, when money crosses the event horizon of a shielded pool its history begins an unstoppable, monotonic march toward indistinguishability.

    Turned 32 today. I agreed to join Zcash almost exactly 10 years ago this week. Just like you can't easily replicate ZEC's fair coin distribution, and you can't buy off our principles, you also can't beat the conviction of die-hard Zcash fanatics. Like @zooko said, we're insane!

    Replying to @ebfull
    Today, I could not even imagine selling my ZEC to "take profits." Ironically, it would make my quality of life worse, not better, regardless of the price. The most leverage I have to make the world a better place is by making Zcash successful. And so I simply refuse to sell ZEC.

    Tachyon consolidates the entire Zerocash protocol into a single distributed key-value store with an append-only log of test-and-set operations using recursive SNARKs. Almost everything is stripped from a txn before it is recorded, and *all* that remains is pruned.
