But first, today’s Top Stories:
🤖 Mythos AI Puts Bitcoin Security On The Clock
🐕 Bark Brings Ark Self-Custody To Mainnet Today
📜 Fed Plan Targets Debanking's Reputation Risk
You've been at this a while. You've read the bitcoin books. You've explained UTXOs at Thanksgiving. But here's the thing: you probably still have blind spots.
Unchained just released Rethink Bitcoin → — a free, interactive course that walks through the bitcoin talking points you're already familiar with—and some you probably aren't yet.
→ 12 lessons spanning the protocol, common misconceptions, bitcoin as savings, multisig and self-custody, network effects, and more.
→ 21 interactive figures that help solidify key concepts: compare bitcoin's cycles to history's famous bubbles, stress-test centralized vs. distributed networks, strip the volatility out of bitcoin's full price history, watch HODL Waves play out, run loss scenarios against singlesig and multisig. The full-spectrum kind of resource you wished existed when you were learning about bitcoin.
→ A clean, easily-sharable three-rule framework — bitcoin is not what you think, bitcoin is long-term thinking, bitcoin is true ownership.

🐕 Bark Brings Ark Self-Custody To Mainnet Today
Second launched Bark, its Ark implementation, on Bitcoin mainnet for users and developers. Bitcoin Magazine says the 11-person team has raised $5.1 million and includes former Blockstream engineers.
Why it matters: Ark does not need to kill Lightning to matter; it can complement it by making self-custody feel less like infrastructure maintenance. The win is sovereign UX that competes with custodians without copying their trust model. Read more→
The UX fight still needs bank access...
📜 Fed Plan Targets Debanking's Reputation Risk
The Federal Reserve's R-1884 proposal would remove reputation risk from bank supervision and has drawn 12,091 listed comments. The comment period closed April 27, and the Fed is reviewing responses before any final rule.
Why it matters: Bitcoin miners, exchanges, treasury firms, and infrastructure providers could get relief from one banking choke point. But regulatory access can swing by administration; Bitcoin remains the escape hatch that does not ask permission. Read more→
