A simplified explanation of the Coldcard issue. When you set up your Coldcard it generates a secret - the words it tells you to copy and keep safely. Turns out it was choosing those words in an easily predictable way (instead of randomly), meaning it’s easy to guess which words a Coldcard would choose. Since it’s easy to guess your secret, anyone can know it. This secret is the key to your Bitcoin - meaning anyone who guesses the secret has as much ownership of the Bitcoin as you do, and can steal it to a wallet they control.

AMM design is being rethought from the ground up, and 1inch Aqua is the clearest signal of where on-chain trading infrastructure is heading. Join us for a technical deep-dive into 1inch's next-generation liquidity protocol: how shared liquidity works, and what it unlocks for LPs, DeFi users, and builders. 🎤 Tanner Moore (@tanz0rz), Technical Account Manager at @1inch What we're covering: • Where modern AMM design falls short: fragmented liquidity, idle capital, LP tradeoffs • What Aqua is, and which of those assumptions it challenges • Shared liquidity in practice: capital efficiency and what it means for LPs • What the design unlocks for swappers • Building on top of or integrating with Aqua If you're building DeFi applications, providing liquidity, or want to understand where on-chain trading infrastructure is heading, this session is for you. 📅 Wednesday, July 15th 🕐Time: 10:00 EDT | 16:00 CET | 17:00 Israel 📍Where: Streaming live on X, YouTube & LinkedIn Register NOW: luma.com/7p4xrxd7 Powered by @MasterkeyVC

This was so much fun! 🤩 Scaffold-Agent is super powerful and easy to use. Paired with tools like @1clawAI and @ampersend_ai you can build all sorts of interesting agents.
AI agents are holding keys and signing txns - usually with no guardrails. At the latest edition of the Underground, @cryptomastery_ (@1clawAI / @edgeandnode) showed the fix: keys live in an HSM, signing in a TEE, spend capped before signing. The agent never sees the key.

1/ Quantum computers are usually presented as a threat to cryptocurrencies. Cryptographically relevant quantum computers would break many assumptions used today. But there is also a longer-term, more optimistic possibility: Quantum cryptography may improve cryptocurrencies.

Fun fact: Bitcoin can be as secure as today WITHOUT ANY MINERS! (And no, I'm not talking about forking to PoS. I said "as secure" lol.) In fact, as long as everyone agrees on the hash of the last tip, you don't even need the internet. With quantum computers, it is possible to completely remove the need for Bitcoin mining in the long term while compromising hardly anything! The existing chain remains as a source of initial truth, and everything else remains offline. Double spending is not prevented by a network of verifiers, but by the laws of physics! Learn all about it from Tuesday's lectures about the quantum promise and threat to Bitcoin. @or_sattath (my Ph.D co-advisor and the S in LSZ) presented the promise, while I explained the threat 👿 The lectures are in English, link to the video in the original post.
~20% of Bitcoin's supply could be stolen by a quantum computer tomorrow. This week we hosted Prof. @or_sattath and Dr. @DesheShai in Tel Aviv to break down what's actually at risk, what's already in flight, and what blockchain looks like after a post-quantum migration. Recap 👇

The fine folks at @Web3_Devs invited me to speak about @papervault_xyz next week. Some might say the implementation is just a UX wrapper of @privy_io's twice-audited zero-dependency SSS lib, and frankly, they would be right. But, nonetheless its served me well over the years.

a16z co-founder Ben Horowitz: “Don’t follow your passion” Ben gives this advice to the Columbia University class of 2015: “Don’t follow your passion. Now I know you’re probably thinking: ‘That’s a really dumb idea because if you poll 1,000 people who are successful, they’ll all say they love what they do. And so the broad conclusion of the world is that if you do what you love, then you’ll be successful.’ But we’re engineers, so we know that might be true. It also might be the case that if you’re successful, you love what you do — you just love being successful, everybody loves you, it’s awesome. So which one is it?” He continues: “The first tricky thing about passions is they’re hard to prioritize. Are you more passionate about math or engineering? Are you more passionate about history or literature? Are you more passionate about video games or K-pop? These are tough decisions. How do you even know? On the other hand, what are you good at? Are you better at math or writing? That’s a much easier thing to figure out. The second thing that’s tricky if you’re going forward in time with this ‘follow your passion’ idea is that what you’re passionate about at 21 is not necessarily what you’re going to be passionate about at 40. Now this is true for boyfriends, as well as career choices. The third issue with following your passion is that you’re not necessarily good at your passion. Has anybody ever watched American Idol? So you know what I’m talking about. Just because you love singing doesn’t mean you should be a professional singer. And then finally, and most importantly, following your passion is a very ‘me-centered’ view of the world. And when you go through life, what you’ll find is that what you take out of the world — money, cars, stuff, accolades — is much less important than what you put into the world. And so my recommendation would be to follow your contribution. Find the thing that you’re great at, put that into the world, contribute to others, help the world be better. That is the thing to follow.” Video source: @a16z (2015)
