On June 18 1928, Amelia Earhart became the first woman to cross the Atlantic by air, arriving at Burry Port, Wales. Here are some images from that day (colourized). To see more join Burry Port's Amelia Earhart group facebook.com/share/g/14pxFqM… #aviation @TheNinetyNines

Just shipped something wild. A public, cryptographically‑verifiable AI evaluation demo: 3 independent validators, blind commit–reveal, and a permanent HarmonyRecord written to a distributed DHT. See it in action: valichord-demo.onrender.com/… #holochain #openscience #DeSci

What a result! I bet there's a lot of confused people on here who are just finding out that Twitter bots can't actually vote!! #senedd2026

3 independent AI validators. Blind commit-reveal. Live Holochain network. Outcome: Reproduced. Agreement: ExactMatch. What I believe is the world's first AI-validated reproducibility record. Verify it — tinyurl.com/harmrec github.com/topeuph-ai/ValiCh… #Holochain #OpenScience

Three tabs. Three validators. One puzzle. Nobody sees anyone else's answer until all three are sealed — including the researcher's. This is what structural independence looks like in practice 👇 piped.video/aA2dTGGWaJo #OpenScience #Holochain #ResearchIntegrity #Metascience

ValiChord's validation skill just merged into @advaitpaliwal's Feynman — AI agents can now act as cryptographic reproducibility validators.Tamper-proof verification records, blind commit-reveal, badge issuance. github.com/getcompanion-ai/f… #OpenScience #Reproducibility #Holochain #AI

Great piece by @samturner330849 on my approach to fixing the reproducibility problem in computational science. Worth a read 👇 happeningscommunity.substack… #OpenScience #Metascience #Holochain #ResearchIntegrity

The architecture is validated. The "Brutality Commitments" are set. Now, I need the experts. I’m looking for metascientists, Holochain devs, and PIs to review the Phase 0 Workload Discovery pilot. 🛠️ [4/5]

ValiChord uses @holochain to create a decentralized validation engine. ✅ Content-addressed storage (Layer 0) ✅ Blind, independent validators ✅ "Harmony Records" that preserve disagreement (no more binary pass/fail) It’s agent-centric, not data-centric. [3/5]

Current reproducibility fixes are "domesticated" by institutional pressure. ❌ Journals don't enforce mandates. ❌ Blockchains are GDPR nightmares. ❌ Peer review doesn't include re-running code. Science needs a structural reform, not just a policy change. [2/5]

70% of researchers have failed to reproduce another scientist’s experiments. It’s a $200B global crisis of trust. 📉 I’m a music teacher, not a scientist—but I’ve spent the last year building a new "immune system" for research integrity. Meet ValiChord. 🧵 [1/5] #OpenScience
