Made a draft ZIP for turning Sapling withdraw only: github.com/zcash/zips/pull/1… Stats at a glance: - 1.2% of non-mining pool transactions were Sapling - Of those, they are predominantly withdrawing Lets get everyone into Quantum Recoverable, Formally Verified pools!

Happy 10th anniversary, Zcash! I put together this short documentary to tell the story of the Sprout ceremony from October 2016, which gave birth to the first zero knowledge proof privacy coin! Featuring @peterktodd @zooko @ebfull @EliBenSasson @rel_zeta_tech @Snowden

FWIW, @ZcashCommGrants funded @equilibrium_co's github.com/runziggurat, a network crawler + fuzzer still used today by teams like @ZecHub and tools like @zecblock. During its audits, we discovered a handful of critical bugs that could have taken down Zcash in 20 minutes.

This week, for the first time, starting to question whether Zcash is really going to be the money of the future. We have wallet devs attacking other wallets, people trying to stop proposal discussion before it even starts. Starting to feel like Bitcoin. Not the good parts.

These attacks to ZCG and the Dev fund were simply coordinated during the day that launched a decade of Zcash. Very bad timing of discussion because most voices are out, very bad faith of the organizers. Be cautious of individuals who use tweets only to criticize others, in practice, they resemble the big bad wolf. ⚠️ An “org” is attempting to dismantle the “Zcash community” from within, this “org” offers nothing new and acts as a copycat and is trying to buy the reputation though distracted. It shows the most toxic behavior I have observed. I hold a dossier detailing how harmful this group is to Zcash, perhaps the worst ever created. Be careful with distractions.

It looks like the debate over the Dev Fund and ZCG is heating up again. Seems like a good time to reshare my thoughts on the topic.

they should do The Dropout season 2 going through the trial and after with Amanda Seyfried playing Elizabeth Holmes again and then when they get to You Can See Everything filming Elle Fanning plays Amanda Seyfried

Privacy is free now because people don't understand privacy. It won't be free once everyone understands privacy. zcash:native

this post here is causing unnecessary drama people are somewhat mad because the @Zcash account is educating the community on ongoing R&D by @ShieldedLabs (an independent zcash contributor) -- in a harmless post that clearly categorizes it as "proposed" some more context ⬇️ crosslink is a proposed hybrid pow/pos upgrade for zcash. nothing is decided. both research, development and community discussions are still ongoing. it keeps mining for block production and adds a parallel finality gadget so confirmed blocks become irreversible in practice. shielded labs is the independent swiss organization building it. founded in late 2022 by @aquietinvestor as a donation-funded group outside the development fund and block rewards. @zooko is CPO there. the team has former ECC and equilibrium people plus other protocol engineers. their whole point is to add independent capacity so Zcash is less dependent on any single US-based entity. that's great for decentralization! they published the crosslink roadmap in march 2025 and have been shipping prototype milestones since then (placeholders, disconnected BFT, PoW respecting finality, staking semantics). by early 2026 the prototype phase was done and they moved into incentivized feature nets and productionization. so roughly a year and a half of public implementation work on top of earlier design discussion. it matters because pure pow tends to centralize over time. bitcoin started with many miners of similar size and now two mining pools produce more than half the blocks. that's an inevitable outcome for the game theories behind BTC pow. i've written extensively about that (and others have too). larger operators get more rewards, buy more specialized hardware, and smaller ones get priced out by difficulty and energy costs. capital is tied to equipment that can be pointed at other chains or sold, so the network stake is weak. in a hybrid setup the pos side puts value at stake that is cumulative and locked to the network itself. an attacker has to compromise both layers. staking stays inside the shielded pool with batching and other privacy measures so individual positions are harder to fingerprint. finality also makes deposits, bridges, and everyday payments more predictable without waiting on probabilistic confirmations. transactions become faster and more aligned to real-world payment expectations. it does not replace PoW. it adds a complementary security model and better long-term sustainability as issuance declines, while expanding who can participate beyond a few large miners. that addresses the empirical centralization path pure proof-of-work has shown, without throwing away the base layer $ZEC already has. i support the direction. independent teams building in public and having their year-and-a-half work being recognized by a simple and harmless post that is now being weaponized by governance adversaries.
Crosslink is a proposed hybrid PoW/PoS upgrade for Zcash. By standardizing staking bonds into incremental powers of 10, observers are prevented from easily inferring individual staking patterns, preserving privacy and maintaining accountability among finalizers.

Whats funny is that, in the end, it's Claude's paternalism thats going to get me to go fully open source.

Baby born with a moustache? Viral video sparks laughter online 👶 A video showing a newborn baby with a thick, dark moustache has gone viral on social media, with users joking that the baby was “already tired of his 9-to-5 job” and had “skipped childhood.” However, according to WION, the video appears to have been digitally manipulated, with signs suggesting the moustache was added using an AI filter or editing tool. While newborns can naturally have fine facial hair, experts say a thick, adult-style moustache like the one shown in the clip is highly unusual. The baby's apparent moustache has not been independently verified as genuine.

Hmm... block every number that's not in your phone's contacts and route everything else to Google Voice for async screening?
We made the first AI model you can have a realistic conversation with that was trained entirely on speech! Dessa is a full-duplex speech-to-speech model that you can run on consumer GPUs. This is a GPT3 moment for speech.
