The math behind confidential transactions! Two payments of 40 USDT on a confidential chain. Can anyone tell they are equal? hathor:native

Two payments of 40 USDT on a confidential chain. Can anyone tell they are equal? Pedersen Commitments Challenge 1. Proofs in the replies; the first clean one gets credited in the solution.
Pedersen Commitments Challenge 1. Let G generate a group of prime order q, and let H₁, H₂ be the points of their tokens (the same token or two different ones). Fix any amounts v₁, v₂, and pick r₁, r₂ independently and uniformly at random mod q. Commitments: C₁ = v₁·H₁ + r₁·G and C₂ = v₂·H₂ + r₂·G. Prove that P(C₁ = C₂) = 1/q. What it means: unlike a plain hash of the amount, equal amounts do not give equal commitments. Two payments of 40 USDT collide with probability only 1/q, about 2⁻²⁵⁶ on secp256k1. This alone does not prove that a commitment reveals nothing about its amount. That takes a stronger result: perfect hiding. Answer in the replies. @msbrogli

Privacy isn’t on or off. It comes in levels👇
Marcelo Salhab Brogliato
@msbrogliOct 22
On most public chains, every payment shows who paid whom, how much, in which token, and where the coins came from. Analysts follow that trail to real names. Privacy isn't on or off. It comes in levels. Six levels, what each one hides, and what still shows. 🧵

Our privacy testnet is live: try hiding a payment's amount and token in the mobile wallet. Privacy isn't on or off. It comes in levels, and the more you hide, the more work every node does to check it. I'll post about them soon. What would you want hidden next?

Pay for coffee with crypto? Think again. Blockchain Forensics by @msbrogli👇
Marcelo Salhab Brogliato
@msbrogliOct 19
You pay $1 for a coffee with a stablecoin. Your barista can see you hold $100,000 and earn $12,500 a month. If the café uses one address, so can anyone who buys a coffee there. And see when you come in: Mon, Wed and Fri, around 9 am. That's blockchain forensics. Here's how. 🧵

Tokenization is on everyone’s mind. We built it natively into Hathor 6+ years ago. Since then, hathor:native has supported $250M+ in tokenization. Before “RWAs” became the buzzword. The future we built for is finally here.

.@msbrogli talks about the reality of blockchain speed claims
Marcelo Salhab Brogliato
@msbrogliOct 16
In 2018 the BMJ published a randomized trial of parachutes. Jumping from a plane with one was no safer than jumping with an empty backpack. The trial was careful and correct. The planes were parked. Many blockchain speed records are set the same way. Here's how to tell. 🧵 Average altitude 0.6 m. Average speed 0 km/h. Nobody in either group died or was seriously hurt. The trial ran in the BMJ's Christmas issue, and its lesson is serious. The point: a test can be done right and still say nothing about the hard part, if it runs where the hard part can't happen. Tempo's published benchmark is one example. Its methodology page: "two local validators in consensus on a dedicated bare-metal server."
The planes were parked. A randomized trial of parachutes. Two panels. Top, "In the trial": a plane parked on the ground, average altitude 0.6 m, speed 0 km/h, 23 people enrolled. Bottom, "Screened, did not take part": a plane in the sky, 9,146 m, 800 km/h, the other 69 screened. Source: Yeh et al., BMJ 2018;363:k5094.

Magicians hand you the box to inspect. The box is real. That's the trick. The Ledger implant in the news this week works the same way. Genuine Check passes, because the chip it checks really is genuine. The theft happens on three wires right next to it. 🧵

TPS insights by the legend @msbrogli 👇
Marcelo Salhab Brogliato
@msbrogliOct 8
The blockchain industry loves big TPS numbers. 10K. 100K. 1M. Now Sui's 40M. A nerd joke: a farmer asks a physicist how to make his cows give more milk. The physicist finds a perfect solution. There's just one catch: it only works for spherical cows in a vacuum. Many TPS numbers are like that. They are true, but only under conditions that real networks don't have. The joke is about simplifying a real problem so much that the answer only works on paper. 🧵

It’s been really nice watching $HTR price action over the last few weeks. The team, tech, and community deserve this Still one of the most undervalued L1s despite the recent 5-6x though. May the altcoin bullrun take it toward past highs I'll still hang around and follow developments but this will probably be my last tweet about Hathor. Good luck to all🫡
