With the small caveat that it will probably get me killed one day, my favorite tactic is blasting this and staring the guy down, expressionless, without breaking eye contact until he gets the hint.

All cops are broadcasting: Obtaining the secret TETRA primitives after decades in the shadows (47:30) (youtu.be)

In this talk we will discuss the radio jailbreaking journey that enabled us to perform the first public disclosure and security analysis of the proprietary cryptography used in TETRA (Terrestrial Trunked Radio): a European standard for trunked radio globally used by government agencies, police, prisons, emergency services and...

Homomorphic encryption solves this…

You bring up some valid points about readability and auditability, and I can see where the confusion might come from. Let’s break it down a bit.

  1. Readability vs. Auditability: With homomorphic encryption, you can perform calculations on encrypted data without needing to decrypt it first. So, yes, the data can be audited without being fully readable. Think of it like checking a locked treasure chest’s contents without actually opening it!
  2. Selling Votes and Security Concerns: Zero-knowledge proofs are like saying, “I know the secret, but I won’t tell you what it is.” They allow the system to verify information without exposing the details. It’s a cool concept that’s been researched for decades, and it has applications in keeping things like medical records secure.
  3. Why Blockchain? Imagine a public ledger that no one person controls and can’t be easily tampered with. That’s what blockchain brings to the table. It creates a system where we can trust the process because the data is transparent and immutable.

Here’s a real-world example: ElectionGuard uses this technology to ensure that electronic records match physical ballots. They encrypt the records in a way that can be verified without exposing individual votes.

what’s the design goal?

To create the capabilities for a direct democracy that is far more secure and auditable than the current system.

I hope this helps make things clearer! Feel free to hit me back with any more questions. It’s a complex subject, but it’s super interesting once you start to get the hang of it.

This Guy Built an Endgame Rocket Espresso Machine | An Engineer's Rocket Appartamento Mods [12:12] (youtu.be)

My first espresso machine, a rocket appartamento, has turned into a testbed for all my ideas of how much technology you can pack into an espresso machine. Let me share what I’ve done, and please ask about what you would like to hear more of!...
