Liquid Network: ~4,000 BTC out Sunday; Tuesday wires say ~3,400 returned

liquid bitcoin blockstream
Decrypt
  • Sun: purported white-hats withdrew ~4,000 BTC (~$320M) from Liquid’s federation wallet that backs L-BTC — ~95% of ~4,200 BTC reserves (Cointelegraph / Decrypt).
  • Path: bug-minted unbacked L-BTC pegged out via SideSwap’s PAK; federation keys not compromised; bridge nodes disabled; other Liquid assets (USDT etc.) untouched.
  • On-chain negotiation: actors demand Elements patch on every node before returning most coins; Blockstream exchanged PGP-signed BTC messages (Cointelegraph update).
Why it matters — A federated Bitcoin sidechain lost nearly all reserve BTC without a key theft — mint-then-peg-out — and recovery is still incomplete while the bridge stays paused.

Australia: “My Feed, My Way” — draft duty of care with algorithm opt-out

  • PM Albanese / Comms Minister Wells (Tue): draft Digital Duty of Care for targeted consultation; legislation aimed this year.
  • “My Feed, My Way”: platforms must notify users 16+ and let them opt out of personalized algorithm feeds — follow-only default instead.
Why it matters — After the under-16 social ban, Canberra is exporting a recommender-opt-out model with nine-figure fines — a template Europe will watch.

Buckmaster: forced Euler blowup with LLMs — and an OpenAI pressure story

  • NYU’s Tristan Buckmaster + Anthropic’s Levent Alpöge publish finite-time blowup (smooth forcing) for incompressible porous media, Boussinesq, and 3D Euler; hypo-dissipative Navier–Stokes Lean not ready (statement.pdf).
  • Credit Córdoba / Martínez-Zoroa’s forced-blowup program; heavy Claude / Codex (GPT-5.6 Sol) / Astra use — Euler writeup called “AI slop” under time pressure.
Why it matters — A Clay-adjacent fluid breakthrough collides with lab rivalry and credit politics — the math and the conduct claims both need primary reading, not summary-of-summaries.

PISA 2025: OECD reading freefall; Germany worse again

  • heise on OECD release: OECD reading −28 pts 2015→2025; math −22; science “comparatively stable” over 10y (Cormann).
  • Germany vs 2022: science 486 (was 492), reading 465 (480), math 464 (475) — below PISA 2000 too.
Why it matters — Reading is the load-bearing skill for everything else — and Germany’s slide continues while half of 15-year-olds already use AI chatbots weekly for learning.
