"Privacy commissioners find TikTok collected sensitive data from Canadian children" https://www.cbc.ca/news/politics/tiktok-privacy-commissioners-1.7640974

My thoughts on this quote: "Youth may be less aware of privacy risks, and susceptible to the techniques used to capture their attention, induce them to disclose certain information or adopt certain purchasing behaviours"

Ugh. I wish it were just youth... I think the more accurate statement is this:
The majority of people of all ages are not aware of privacy risks and are susceptible to techniques used to capture their attention.

Here we go again. Whenever policy makers insist that there’s some “nerd harder” solution to tricky societal problems, actual experts have to spend a ridiculous amount of time explaining basic reali…

Vitalik Buterin suggests that Ethereum
will be ready for the on slot of quantum computing suggesting a quantum machine could break blockchain cryptography between 2030 and 2035. The Ethereum Foundation is working to integrate zkEVM ( Zero-Knowledge Ethereum Virtual Machine) within layer 1, within twelve months.

Zero-Knowledge Proofs are now open source, because letting everyone see your invisible tech is obviously the best way to keep it secret. 🔐🤫 Meanwhile, #Google wants to know how often you use their AI tools, because apparently they haven't been tracking your every swipe and click already. 📈👀

Opening up ‘Zero-Knowledge Proof’ technology to promote privacy in age assurance

Today, we open sourced our Zero-Knowledge Proof (ZKP) libraries, fulfilling a promise and building on our partnership with Sparkasse to support EU age assurance.

Google's making a major move in privacy, and it involves something called "Zero-Knowledge Proofs." 🤔 What's this crypto magic, and how will it change your digital life? https://www.patreon.com/posts/googles-privacy-128185686?utm_medium=clipboard_copy&utm_source=copyLink&utm_campaign=postshare_creator&utm_content=join_link #Google #Privacy #Crypto #Blockchain #ZeroKnowledgeProofs #Tech

Ah yes, the riveting tale of solving #Sudoku with zero-knowledge proofs while speedrunning Mario—because why not combine obscure math with video game nostalgia? 🎮✨ Just what the internet needed: a blog post that’s as clear as a zero-knowledge proof itself—utterly unintelligible. 🤯
