The Human Root of Trust – public domain framework for agent accountability

I've spent my career at the intersection of identity, trust, and distributed systems. The thing I keep thinking about: every digital system we've built assumes a human is on the other end. Bank accounts, contracts, API keys — all designed around human singularity. That assumption has already broken. AI agents are transacting, communicating, and signing contracts autonomously — passing identity checks designed for people, with no human visibly in the loop. The Human Root of Trust is my attempt to name the problem and sketch the architecture: three pillars (proof of humanity, hardware-rooted device identity, action attestation), a six-step trust chain from human principal to cryptographic receipt, and two implementation paths. It's dedicated to the public domain. No patent. No product. No ask except that whoever picks this up carries the principle forward. https://humanrootoftrust.org Comments URL: https://news.ycombinator.com/item?id=47100935 Points: 6 # Comments: 1

5 European nations to make drones by tapping Ukraine’s war experience

Five European nations have announced a new programme to produce low-cost air defence systems and autonomous drones using Ukrainian expertise hard-won over the past four years of war against Russia. Friday’s initiative of the E5 nations – France, Poland, Germany, the United Kingdom and Italy – comes as one of many European efforts to bolster defence along their borders, like a “drone wall” with Russia and Ukraine to better detect, track and intercept drones violating Europe’s airspace.

NASA targets March 6 for Artemis 2 launch to take astronauts around the Moon

The Artemis 2 launch is edging closer as NASA has now set a target date for the 10-day mission to get underway. The agency is aiming to launch as soon as March 6 following a successful wet dress rehearsal on Thursday. The first attempt, which took place in early February, failed due to a hydrogen leak. During Thursday's rehearsal, NASA was able to fuel the Space Launch System (SLS) rocket with more than 700,000 gallons of liquid propellant and complete two runs of terminal count — the final step of the launch countdown — at the Kennedy Space Center in Florida. While there was a hiccup due to a loss of ground communications, NASA was able to move to a backup system before the regular comms channels were back in operation. The agency said engineers pinpointed the equipment that caused the problem. "Following that successful wet dress yesterday, we're now targeting March 6 as our earliest launch attempt," Dr. Lori Glaze, NASA's Moon to Mars program manager, said at a press conference on Friday. Glaze added that there's still much that has to be done before launch, including an analysis of the wet dress, a flight-readiness review and work on the launch pad. The four Artemis 2 astronauts are expected to go into quarantine later on Friday in preparation for the launch, which will mark the Orion spacecraft’s first crewed mission. It will be the first time in more than 50 years that a crew will travel around the Moon and it will be humanity’s furthest-ever journey into space. The astronauts will test Orion’s critical life support systems as a precursor to lunar landings.

LA County lawsuit accuses Roblox of exposing children to 'grooming and exploitation'

Los Angeles County has sued Roblox for "unfair and deceptive business practices," claiming the platform's moderation and age-verification systems are inadequate. "Roblox portrays its platform as a safe and appropriate place for children to play," the complaint states. "In reality, and as Roblox well knows, the design of its platform makes children easy prey for pedophiles." Representatives accused Roblox of failing to implement adequate platform safety features to prevent child endangerment. "Specifically, Roblox has not effectively moderated game content or enforced age-appropriate restrictions and warnings established by the creators, allowing the predatory and inappropriate language and interactions between users to persist," the County stated. It also said the platform failed to disclose any danger to children, including sexual content and the risk of predators. Roblox rejected the allegations, saying the platform was built around safety. "We have advanced safeguards that monitor our platform for harmful content and communications, and users cannot send or receive images via chat, avoiding one of the most prevalent opportunities for misuse seen elsewhere online," the company told the AFP. The LA county complaint is the latest in a string of lawsuits from US regions including Florida, Texas and Kentucky. The Attorney General in Louisiana also accused the company of having a "lack of safety protocols" that endanger the safety of children in favor of "growth, revenue and profits." That state's lawsuit cited a specific example of a subject arrested last year that used voice-altering tech to mimic a younger feminine voice to lure and sexually exploit young players. Roblox has said that it has about 144 million daily active users around the world, with over 40 percent of them under the age of 13. However, it has faced repeated accusations that it doesn't do enough to protect young players. In 2024, Roblox banned players under 13 from accessing some types of in-gam

Show HN: Fostrom, an IoT Cloud Platform built for developers

Hey HN! Arjun and Sid here. Fostrom is an IoT Cloud Platform designed for developers to make it really easy to get started and scale fleets. We have Device SDKs (in Python, JS, Elixir, more coming soon), Typed Schemas, Per-Device Mailboxes, Programmable Actions, 4 Global Regions for lower-latency connections, and much more. We've built Fostrom to solve a real need we faced in our previous startup, building a fully automated indoor vertical farm. We spent more time figuring out IoT infrastructure than writing automation logic. Fostrom is the platform we wished existed back then. Over the last few years we've experimented with a lot of interesting tech and architectures, and settled on an architecture that we believe is quite elegant. We wrote a GoElixir bridge to execute JS code in WASM for Actions, implemented a DuckDB library for Elixir, and wrote a Device Agent in Rust that our SDKs run in the background (https://github.com/fostrom/devicekit). The most interesting realization we had was about the data architecture. For years, we tried using distributed databases and built complex layers on top of them, but all approaches had significant limitations specifically around consistency and querying. We want to provide operational correctness, rich insights, and reliability. Finally, we came to the conclusion that to achieve this we really need a SQL database for fleet data. So we built a DuckDB-based replicated multi-tenant data layer. We're still improving it (hence the Technical Preview badge) but we're quite proud of this decision. It simplifies the rest of the codebase, while keeping operational complexity in just a few places. Our vision is to make a powerful IoT platform that enables you to build correct, secure, and reliable connected systems without dealing with any of the plumbing or infrastructure. Next up, we're gonna launch our CLI, add automatic device monitoring to our Device SDKs, and improve the debugging experience. We have some pretty cool ideas to mak

Chinese scientists put quantum chaos in ‘slow motion’

In a landmark achievement, Chinese scientists have directly observed and manipulated prethermalisation – a critical transitional state in quantum systems – using the 78-qubit “Chuang-tzu 2.0” superconducting processor. This allows researchers to “tune” the speed of quantum decoherence, providing a vital tool for managing complex quantum environments. If a quantum system is disturbed, it naturally returns to a balanced state. The energy and information within it spreads out until they are evenly...

Texas is suing TP-Link over its ties to China

Texas Attorney General Ken Paxton is suing TP-Link over claims that the router-maker is misleading customers about its ties to China. In a lawsuit filed this week, Paxton claims TP-Link is "masking its Chinese connections," while serving as "an open window for Chinese-sponsored threat actors and Chinese intelligence agencies." TP-Link was founded in China, but has attempted to distance itself from the country in recent years. In 2018, the company established a manufacturing facility in Vietnam, and then centralized its global headquarters in the US in 2024, forming TP-Link Systems. Though TP-Link markets its routers and other products as " … Read the full story at The Verge.
