    35% of US employment is spent creating trust. Auditors, notaries, attorneys, courts, custodians, compliance officers. Trust-establishing work is the single largest category in the modern economy. It is also being repriced. The repricing started in financial infrastructure.

    Say blockchains without saying blockchains. Apple: "Publishing ... in an append-only and cryptographically tamper-proof transparency log" which is "publicly available for inspection"

    Of course, knowing that the phone is running a specific piece of software doesn’t help you if you don’t trust the software. So Apple plans to put each binary image into a “transparency log” and publish the software. But here’s a sticky point: not with the full source code. 11/

    1/ Seeing a lot of excitement on FHE recently. Here's my take in a thread: for trust-minimized applications, FHE is a game changer that enables application-level privacy. However, for it to truly shine, FHE needs to be used *alongside* other tools such as MPC and ZKP. 👇

    Unpopular opinion: Solana is repeating Eth's footsteps 4 yrs ago. - Increase in fees signals a start to global congestion (fortunately Solana blocks are mostly <80% full rn) - Global congestion leads to rapid rise in min fees - Rise in min fees leads to exodus of apps and users

    1/ Google announced that Google Wallet will be using "ZKP" to support "fast and private age verification". But wait, what type of ZKPs are they actually using?

    Want to know why ZK is not the (full) end-game solution to privacy on public blockchains and how threshold (F)HE can help? Don't know what ZK/FHE means but want to know more about privacy on public blockchains? Read my post to find out! wdai.us/posts/navigati…

    1/ Why I'm excited about investing in crypto infra 🧵 Crypto and trust-minimizing technologies will transform foundational infrastructures across industries. As an ex-academic and now investor, I strive to find, fund, and partner with 0-to-1 innovators and 10x disruptors.

    As a crypto project, you are building two products: 1. The token (that accrues value) 2. The core product (that generates value) Having a clear mental separation between the two allows you to think clearly about ways to make these two products synergistic.

    We have @VitalikButerin on stage at ETHGlobal Taipei discussing Ethereum in 2025 and addressing a common misconception: that if most activity happens on Layer 2s, we can ignore L1 scalability. He argues that most L2 apps heavily benefit from at least some L1 use: - L1

    1/ Will we see thousands or even millions of L2s? Only if L2s can horizontally scale without compromising trust-minimization. In this short post, I argue in favor of trust-minimized systems that can horizontally scale. mirror.xyz/1kx.eth/gEzEkg… Summary below 👇
