Today is a great reminder: centralized systems fail. Bitcoin and Nostr don’t.

“A failure to understand proof of work is a failure to understand Bitcoin.” – Jack Mallers, BTC Prague Proof of Work is the mechanism that makes Bitcoin trustworthy. Here’s how it works in simple terms: 🔹 Thousands of computers worldwide race to solve a mathematical puzzle. 🔹 The winner adds the next “block” of transactions to Bitcoin’s ledger. 🔹 This process requires energy, which makes cheating extremely costly. 🔹 The system automatically adjusts so blocks are added about every 10 minutes. The result? A network that no one can control, no government can censor, and no single company can shut down. That’s why Proof of Work isn’t just a feature of Bitcoin — it’s the very reason Bitcoin works.

Happy Bitcoin Infinity Day 🔥 ♾️ / 21M

"Fiat is the bubble, Bitcoin is the pin." – Dominic Frisby Our current fiat monetary system constantly inflates the money supply, creating an ever-growing bubble in asset prices and debt. Bitcoin, with its fixed supply of 21 million, acts as the “pin” – exposing the fragility of fiat and offering a sound, deflationary alternative. In other words, Bitcoin doesn’t create the problem. It reveals it.

Money moves in centuries-long cycles. From the first cash notes in the 1600s to Bitcoin in 2014 — every shift has redefined money. Dominic Frisby argues we’re entering a new era. Full keynote on YouTube 🔥
