Nice calculator
How much BTC do you need to retire?
SO MUCH MORE than some would lead you to believe (IMO).
Assuming:
- retire next year
- live for 50 years
- $100k / annum
- 10% inflation
- spend stack to 0
What's your take?

Instead of watching an hour of Netflix watch this 30 minutes lecture and learn more about bitcoin mining than most people working at top Bitcoin companies learn in their entire careers.

Interesting.
Roland Fryer ran the numbers on millions of police encounters. Low-level force showed some racial bias. People liked that finding.
Police shootings showed none. He expected the opposite. He hired a second team of eight researchers and got the same result.
Colleagues told him not to publish. “You’ll ruin your career.” They wanted the convenient half of the paper and the inconvenient half buried. He published both. Then he bought diapers with an armed guard.

New @mempool feature: BIP54 Compatible Coinbase detection
BIP-54 aka. Consensus Cleanup specifies (among three other rules) that coinbase transactions must set nLockTime = height - 1 and nSequence ≠ 0xffffffff.
Ahead of activation, the BIP encourages mining pools to craft coinbase transactions that are forward-compatible with this rule.
Whitepool was the first to adopt, with block 937,404 in February 2026; a handful of other pools and unknown miners have followed since. Now you can easily see when a block is compatible.
For now it only shows if a block is compatible, signaling incompatibility will be added when support is more widespread.

~90% of ASICs run one vendor's closed-source firmware. Almost nobody has audited it.
We at @256FOUNDATION do.
Introducing the 256 Red Team 🧵 — the 256 Foundation's firmware security program. On hardware we own, in an isolated lab, under coordinated disclosure.

🤓 Our NEW deep dive of the Coldcard disaster is out!
This one covers:
- The ACTUAL entropy level
- The collision risk
- The multiple sources of "entropy", and how each was triggered
It's extremely long, I couldn't review it all yet.

I did my own investigation because I obviously don't trust them.
What I found is that the external dependency of the firmware with the critical vulnerability hidden in it was written by CoinKite's CTO @DocHex pretending to be someone else.
All of the following can be verified:
