Eastern Point (music and video) is my love letter to Gloucester and all its daily seafarers. It features a real short-wave radio marine warning, as well as a recording of T.S. Eliot reading a portion of The Dry Salvages. I hope you like it! piped.video/watch?v=jn15gw2c…

Ah yes, you're coming from Bitcoin, where Core devs intentionally undermined retail 0-conf payments by forcing RBF by default. For starters, Zcash blocktimes are 75s and dropping to 25s in November. But moreover, there is no 'replace by a higher fee' in Zcash. When you spend a shielded TX and it reveals its nullifiers, as soon as it's accepted in the mempool, nodes reject any second transaction that spends the same nullifiers. Double-spending to attack a merchant is not something Zcash supports, whereas Bitcoin made it blatantly easy.

I think "upgrading to Zcash" is even more obnoxious than "encrypting your Bitcoin" FWIW. I like it.

The entire market cap of Zcash telling you it wasn't exploited. No-one cogently stands behind the game theory of an attacker or how the pool isn't drained yet. Its been formally verified to have no other undetectable soundness bug possible. So it can't happen again.

"We are all made of starstuff" - Carl Sagan
🚨 PHYSICS IS BROKEN! MATTER IS AN ILLUSION, THE ATOM IS JUST TRAPPED LIGHT! A NEW ERA HAS BEGUN! 🚨 For 100 years, physics has treated "mass" as a fundamental, solid particle floating in an endless, empty void (ℝ⁴). What if that is a complete mathematical hallucination? What if mass is just light that got stuck in the geometry of space? A year ago, we thought exactly like the academic establishment. Breaking a lifelong paradigm and reinterpreting everything from scratch is incredibly difficult. But mathematics is a stubborn thing. We realized one absolute truth: the infinite ℝ⁴ space is fundamentally defective in physics. It exists purely as an abstract mathematical concept, and we must finally understand that pure mathematics ≠ physical reality. We genuinely need your help to break this dogma! DO NOT TAKE OUR WORD FOR IT. DO NOT BLINDLY TRUST AUTHORITY. We wrote the code, we solved the math, and we are giving it to you for absolutely free. Read the preprint and verify it yourself. Look at the real quantum photographs attached. On one side is the groundbreaking 2013 photograph of a Hydrogen atom's electron orbital, captured by researchers at the FOM Institute AMOLF in the Netherlands using a quantum microscope. On the other side is the famous 2015 photograph from EPFL in Switzerland, capturing light behaving simultaneously as a wave and a particle. Notice the absolute revelation: they are visually identical. Atoms are not solid little billiard balls. They are concentric interference patterns-pure standing waves of energy. The ultimate conceptual shift of our IT³ framework is this: The atom is not a "box" that contains trapped light. The atom IS the trapped light. There is no abstract container. There is only the geometry of the vacuum (a discrete lattice) which mathematically forbids light from propagating past certain algebraic boundaries. How it Works (Explained simply from the video): Let’s break down exactly what you are seeing in the simulation engine: 〰️ The Cyan Wave (→): A free gauge photon travels smoothly through the quantum vacuum. 🛑 The Kummer Wall (Red Lines): Suddenly, the light hits the absolute edge of the spatial lattice. This is an algebraic cutoff where mathematics literally runs out of resolution (√13 ∉ 𝕂). Space "does not exist" beyond this boundary. 🪞 Total Internal Reflection (Purple Wave ←): With nowhere left to go, the photon undergoes complete topological reflection. It bounces back as its own precise mirror image-an antiphoton. ⚡ The Birth of Mass (Yellow Core): The two opposing waves crash into each other and geometrically interlock. They form a perpetual, vibrating "standing wave" whose energy is trapped in one place. This localized density of confined energy is exactly what we call REST MASS. The Counterfactual Test: Watch the timeline in the visualizer. When the system hits the "WALLS OFF" phase, we computationally delete the vacuum boundaries. The golden pulsating core immediately shatters. The light escapes into infinity, and the mass drops precisely to zero. Matter literally un-braids back into pure radiation. FALSIFIABILITY AND PREDICTIONS: The "Mass Gap" is not solved by adding endless, arbitrary parameters to an infinite void. It is solved by recognizing that the Universe is a discrete, constructible topological crystal. Our model is strictly falsifiable and delivers exact predictions: 🎯 It predicts a new topological resonance at exactly 1088.04 GeV, accessible for verification at the High-Luminosity LHC. 🛑 It mathematically proves the absolute end of the periodic table at element Z = 172. 🧮 It operates with ZERO fitted parameters. All physics is reduced to the strict arithmetic of integers. THE HARDWARE CODE OF THE VACUUM MATRIX: 🌌 Arena: ℳ = 𝕊⁴ × 𝕋³ over the field 𝕂 = ℚ(√2, √3, √5) 👁️ Witness: 172 topological elements ⚙️ Processor: 57600 = 240² = 1110 0001 0000 0000₂ 📖 DOWNLOAD THE CODE. BREAK THE MATH. We do not want blind faith. Read the proofs. The supreme judge is the compiler, not closed-door committees. 🔗 Code + Preprint: doi.org/10.5281/zenodo.22655… doi.org/10.5281/zenodo.21555… #Physics #QuantumMechanics #Simulation #OpenScience #MassGap #TheoryOfEverything

Yeah I guess we ARE pretty cool!!!
It’s very telling to see some of the smartest engineers and cryptographers pivot to work on Zcash full time over the past few years. To work on very challenging, impactful problems. Tachyon for planetary scale, NU7 for faster block times, seamless wallet experience, formal verification, quantum resistance etc. Many have committed to this being their life’s work. High agency across the board and no complacency whatsoever. Now when you take these mission oriented, highly capable people across the Zcash ecosystem, and combine them with the best capital allocators (a16z, Paradigm etc.), you tend to see great things happen.

NSM is Zcash's sleeper secret weapon. Privacy and Quantum resistance are necessary but not sufficient to establish a digital monetary asset in perpetuity
